Embodiment

The utility model is described in further detail below in conjunction with the accompanying drawings：

As depicted in figs. 1 and 2, a kind of multi-rotor aerocraft horizontal tilt folding frame, including frame 1, frame 1 set more Individual folding horn 2, the axle center of horn 2 and the angle of horizontal plane after folding are 0~30 degree.

Wherein, described horizontal plane refers to that residing plane is normally placed and used to frame 1；Under normal circumstances, institute After having the stretching, extension of horn 2, the plane residing for wing is also horizontal plane.

Wherein, in a kind of feasible implementation, the axle center of horn 2 and the angle of horizontal plane after the folding are 15 Degree.Relative to vertical jackknife method, after the folding of horn 2 of the folding frame, a larger sky will not be formed between each horn 2 Chamber, the horn 2 after it is folded will not also take big quantity space, and therefore, occupancy volume is smaller after it is folded, and largely saves Space, is convenient for carrying.

Wherein, in a kind of feasible implementation, in adjacent two horns 2, one of horn 2 is on horizontal plane Side folds, and another horn 2 folds to horizontal plane lower section.In this way, the inclination up or down that two adjacent horns 2 interlock, Avoid two neighboring horn 2 while the up or down interference and competition on locus caused by folding.

Wherein, in a kind of feasible implementation, the two neighboring horn 2 in the same side of frame 1, horn 2 is distinguished Fold over to horizontal plane and folded to horizontal plane lower section.In this way, the inclination up or down that two adjacent horns 2 interlock, Avoid two neighboring horn 2 while the up or down interference and competition on locus caused by folding.

Wherein, in a kind of feasible implementation, the root of the horn 2 sets connecting shaft component, connecting shaft component Connecting shaft and frame 1 it is be hinged, the axle center of connecting shaft and the angle of horizontal plane are 90~65 degree.In this way, can direct whirler Arm 2 realizes the folding and stretching, extension of horn 2.

As more specifically embodiment, horn root fixings 3, horn root fixings 3 are set in the frame 1 With locating groove 31；The root of horn 2 sets locating piece 21, and when horn 2 stretches, locating piece 21 is matched somebody with somebody with locating groove 31 Close, and connected by fastener.The cooperation of horn root fixings 3 and locating piece 21 so that horn 2 stretch it is more stable, Durable.

As more specifically embodiment, the horn root fixings 3 are cylinder of the axle center along the direction of extension of horn 2 Body, the locating groove 31 along axis direction is opened up on cylinder；When horn 2 stretches, horn root fixings 3 are common with horn 2 Axle center.More specifically, the diameter of horn root fixings 3 is not less than the diameter of horn 2；The outside of horn root fixings 3 is set Put screw thread；The fastener includes the pipe sleeve 4 being set on horn 2, is threaded on the inside of the end of pipe sleeve 4；When horn 2 is stretched Zhan Shi, the end of pipe sleeve 4 can be connected through a screw thread with horn root fixings 3.In this way, pipe sleeve 4 is to be enclosed on living on horn 2 Dynamic component, when horn 2 stretches, horn 2 is pivoted in the locating groove 31 of horn root fixings 3, then pass through pipe Set 4 and the external screw thread of the front end of horn root fixings 3 are coordinated, fixed horn 2.And when folding horn 2, it is only necessary to back out Pipe sleeve 4, horn 2 is folded all right.

As more specifically embodiment, the pipe sleeve 4 includes pipe sleeve thread segment 41 and pipe sleeve horn section 42；Pipe sleeve spiral shell The inner side of line section 41 is threaded, and it can be threadedly coupled with horn root fixings 3；Pipe sleeve horn section is set on horn 2, its Internal diameter is more than the 0~0.5mm of external diameter of horn 2.In this way, the end of pipe sleeve 4 can be fixedly connected with horn root fixings 3, before it End can be fitted close with horn 2, realize the fixation to horn 2, and then realize the fastening of horn root fixings 3 and horn 2 Connection.

As a kind of actual implementation, as depicted in figs. 1 and 2, four horns 2 of setting, horn 2 are right in the frame 1 It is arranged on the both sides of frame 1 with claiming；When horn 2 stretches, each horn 2 is outwards distributed in divergent shape；When horn 2 folds, Horn 2 positioned at the same side to interior folding, wherein, one to inner side lower section fold, another folds over to inner side, Two just adjacent horns 2 mutually stagger, and the shared space of horn 2 in the plane are so reduced, relative to vertical Folding also reduces the space-consuming of horn 2 in the height direction, and does not have Position disturbance between two horns 2.

Multi-rotor aerocraft horizontal tilt folding frame provided by the utility model, it has the advantages that：

(1) high degree improves the folding efficiency of body.

(2) simply, operation readiness.

(3) durable.

(4) it is convenient for carrying, adapts to Environmental strong.
