Description

Technical Field

[0001] The present invention relates to the field of practical UAV landing technology, specifically to an anti-dumping landing bracket for UAV. Background Art

[0002] At present, the anti-fall brackets of most four-wing UAVs are for landing up and down. This setting does not work for dive landing and easily causes the UAV to tip over. During the landing process, the UAV is prone to tipping forward due to inertia. Once tipping occurs, its wings are easily damaged, causing irreparable losses. In addition, the bracket is not convenient to install on the UAV body and is easy to fall off or loose. Therefore, in view of the above problems, a fall-proof bracket for UAV protection is proposed. Summary of the invention

[0003] The purpose of the present invention is to provide an anti-dumping landing bracket for a UAV to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an anti-dump landing bracket for unmanned aerial vehicles, comprising a drone body, a bracket installed at the bottom of the drone body, a wheel frame connected to the bottom of the bracket, a wheel mounted on the bottom of the wheel frame, the drone body and the bracket are fixedly connected via a fixing frame, the end where the bracket is connected to the wheel frame is semicircular, a fixing lug is provided at the connecting end of the wheel frame and the bracket, the fixing lug is rotatably connected to the end of the bracket via a fixed shaft, a plurality of wheel frame lugs are provided on both sides of the wheel frame, a bracket lug is provided on each of the two sides of the bottom of the bracket, the bracket lug is connected to the wheel frame lug via a spring, four connecting grooves are provided at the upper end of the bracket, and the four corners of the fixing frame are fixedly connected to the four connecting grooves respectively.

[0005] Preferably, a wheel frame bracket is provided at the bottom of the wheel frame, and the wheel is rotatably connected to the wheel frame bracket.

[0006] Preferably, the wheel frame is in the shape of a quadrangular pyramid.

[0007] Preferably, the connecting grooves are provided with circular recessed holes and square recessed holes, the four corners of the fixing frame are provided with corresponding circular protrusions and square protrusions, the square recessed holes and square protrusions are provided with pin holes, and pins are provided in the pin holes to achieve the fixation of the bracket, the fixing frame and the drone fuselage.

[0008] Preferably, the fixing frame comprises two parallel longitudinal rods and a transverse rod arranged between the longitudinal rods, and both ends of the longitudinal rods are provided with a round convex head and a square convex head.

[0009] Preferably, at least two wheel frame lifting ears are equidistantly arranged in the height direction of the same side surface of the wheel frame.

[0010] Preferably, the semicircle at the end of the bracket and the center of the wheel are on the same straight line, and the center line of the wheel frame ear coincides with the center line of the wheel.

[0016] In the present invention, the connection between the bracket and the drone fuselage is connected by a fixing frame, and four connecting grooves are arranged on the upper end of the bracket. The four corners of the fixing frame are respectively fixedly connected with the four connecting grooves. The circular convex head of the fixing frame is assembled in the circular concave hole of the bracket. Due to the circular snap connection, the fixing frame can be effectively prevented from falling off. The square convex head of the fixing frame is assembled in the square concave hole of the bracket, and then the pin holes on the square concave hole are aligned for pin fixing, so as to more effectively prevent the fixing frame and the bracket from falling off.

[0025] like Figure 2 As shown, a wheel frame bracket 4 is provided at the bottom of the wheel frame 5, the wheel 3 is rotatably connected to the wheel frame bracket 4, and the wheel frame 5 is in the shape of a quadrangular pyramid.

[0026] like Figure 3-5 As shown, the connecting groove 11 is provided with a circular concave hole 13 and a square concave hole 14, the four corners of the fixing frame 12 are provided with corresponding circular convex heads 15 and square convex heads 16, the square concave holes 14 and the square convex heads 16 are provided with pin holes 17, and pins are provided in the pin holes 17 to achieve the fixation of the bracket 2, the fixing frame 12 and the UAV fuselage 1, the fixing frame 12 includes two parallel longitudinal rods and a cross bar arranged between the longitudinal rods, and the circular convex heads 15 and the square convex heads 16 are arranged at both ends of the longitudinal rods.

[0027] The wheel frame hanging ears 6 of the present invention are arranged at least two at equal distances along the same side surface of the wheel frame 5 in the height direction, so as to adjust the tightness of the spring 7.

[0028] In the present invention, the semicircle at the end of the bracket 2 and the center of the wheel 3 are on the same straight line, and the center line of the wheel frame hanging ear 6 coincides with the center line of the wheel 3.

[0029] The end of the bracket 2 connected to the wheel frame 5 in the present invention is in a vertical position, ensuring that the wheel 3 is in a vertical position, thereby supporting the UAV fuselage 1.

[0030] The fixing lifting ear 9 of the present invention is provided with a circular interface, and the semicircle at the end of the bracket 2 is arranged in the circular interface. The center of the semicircle at the end of the bracket 2 is higher than the center of the circular interface, so that the bracket 2 can rotate in the circular interface, thereby ensuring the stability of the device and having a certain shock-absorbing effect, effectively reducing the dive impact force of the landing of the drone.

[0031] The working principle of the present invention is as follows: when the UAV is landing, the wheels 3 first contact the ground. When the UAV tends to tip forward due to inertia, the bracket 2 is hinged to the wheel frame 5. At the same time, the connecting end of the bracket 2 and the wheel frame is circular, which effectively reduces the diving impact force of the UAV landing; the spring 7 connected with the wheel frame ear 6 through the bracket ear 8 can play an effective shock-absorbing role, so that the damage to the UAV fuselage 1 is reduced to a minimum; the multiple wheel frame ears 6 on the wheel frame 5 can adjust the tightness of the spring 7, thereby more effectively controlling the landing of the UAV fuselage 1.

[0032] The fixing frame 12 of the present invention can better match the bracket 2 on the drone body 1, so that the bracket 2 can be better utilized. The function of the circular protrusion 12 on the fixing frame 12 is to ensure that the bracket 2 and the fixing frame 12 are not loose. After the square protrusion 16 is aligned with the pin hole 17, the pin is inserted from the pin hole 17 to fix the bracket 2 to the drone body 1, thereby improving the stability of the connection of the bracket 2, avoiding the bracket 2 from falling off, and enabling the bracket 2 to better play the role of connection and fixing.
