According to the top cover structure, the positioning block and the two positioning blocks are arranged at the edge of the bottom surface of the cover body, so that the cover body can be conveniently and rapidly opened and closed.
Description
Technical field
The utility model belongs to agricultural vehicle technology field, specifically, and the particularly cap structure on agricultural unmanned vehicle.
Background technology
Along with social development, the progress of science and technology, the work such as spray insecticide on a large scale in farmland, fertilising are progressively completed by unmanned vehicle.Top cover is the vitals on agricultural unmanned vehicle, plays closed fuselage upper port.Existing top cover is convertible structure, and locks by lockset.In use, top cover not only weight greatly, easily damage; And very inconvenience of folding, not only complex operation, and waste time and energy, the convenience that very impact is used.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of agricultural unmanned vehicle cap structure of folding with convenience.
The technical solution of the utility model is as follows: a kind of agricultural unmanned vehicle cap structure, there is lid (1), described lid (1) is the spherical structure that central high rim is low, and made by carbon fiber composite material, be fixed with a fixture block (2) and two positioning seats (3) at described lid (1) the bottom surface place of keeping to the side, described fixture block (2) and two positioning seats (3) are uniformly distributed at circumferencial direction, interior outer end in each positioning seat (3) bottom is respectively arranged with interior journal stirrup (3a) and outer journal stirrup (3b), in same positioning seat (3), on outer journal stirrup, jointly wear latch (4), the outer end of this latch (4) exceeds the outer of lid (1), at the upper vertical fixing driving lever (5) of described latch (4), the upper end of this driving lever (5) is through positioning seat (3) and the corresponding bar shaped via hole arranging of lid (1), on described latch (4), be set with spring (6), one end of this spring (6) and interior journal stirrup (3a) connect, the other end of spring (6) and driving lever (5) connect.
Lid is designed to spherical structure by the utility model, and not only moulding is simple, and processing and fabricating is easy, elegant in appearance, and height dimension is less, can not increase the height of whole aircraft; Lid is made up of carbon fiber composite material, lightweight on the one hand, can effectively alleviate the weight of aircraft, and on the other hand, structural strength is reliable, is difficult for being damaged.
The utility model is in closing top cover, first the gap between crosspiece under fixture block and lid is snapped in to the edge of fuselage top end opening, lid is carried out on fuselage to Primary Location, then stir two driving levers simultaneously, make the direction motion of two driving levers to lid center, now spring is compressed, when driving lever motion, together with the latch that drive is fixedly connected with driving lever, move, make in the retraction lid edge, outer end of latch, like this lid completely spiral-lock at the opening part on fuselage top, and fuselage top end opening is sealed, finally unclamp driving lever, under the effect of recoil of spring power, driving lever and latch reset, the inwall of the outer end of latch and fuselage top end opening pushes against, under the combined action of two latches and a fixture block, top cover tightly spiral-lock at fuselage top, can not occur loosening or come off.In the time that top cover need to be opened, only need stir driving lever according to above operating mode, make latch retract, then around the fixture block lid that upwards overturns.
Described fixture block (2) is " Z " shape, and the bottom surface of the upper crosspiece of fixture block (2) and lid (1) fits, and fixes by bonding or screw, between the lower crosspiece of fixture block (2) and the bottom surface of lid (1), has gap.Above structure on the one hand between fixture block and lid area of contact large, connect not only firmly but also reliable; On the other hand, the gap under fixture block between crosspiece and lid bottom surface can conveniently be located, and is conducive to lid and fuselage clamping is firm.
For the end face of positioning seat is firmly connected with the bottom surface of lid, the end face of described positioning seat (3) fits fixing by bottom surface bonding or screw and lid (1).
For simplified structure, facilitate processing and fabricating, prevent that latch from coming off, the inner of described latch (4) is bulb, this bulb is spacing by interior journal stirrup (3a).
Beneficial effect: the utility model lid is made up of carbon fiber composite material, not only lightweight, and also structural strength is good; The utility model is by a fixture block and two telescopic latches are set at the edge of lid bottom surface, folding cover quickly and easily, features such as having modern design, simple in structure, processing ease, be easy to transformation, improvement cost is low.
