[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0024] As Figures 1-8 shown in a kind of unmanned aerial vehicle rack with tenon and mortise structure, including bottom plate 100, main plate 200, a pair of side longitudinal beam 300 and four arms 400;Side longitudinal beam 300 includes the cross bar part 301 connecting front arch part 302 and rear arch part 303, the area of cross bar part 301 and main plate 200 assembly is used to assemble battery, cross bar part 301 and the front part of main plate 200, the rear part mortise connection of bottom plate 100, the front end of front arch part 302 and the front end mortise connection of bottom plate 100, the rear end of rear arch part 303 and the rear end mortise connection of main plate 200, form wiring cavity between main plate 200 and bottom plate 100, four arms 400 are inserted from the front and rear ends of wiring cavity respectively, and are mortise connected with the cross bar part 301 of two longitudinal beams, main plate 200, arm 400, bottom plate 100 are connected together by fastener (four bolts can be used).

[0025] Specifically, the top surface of the crossbar part 301 is provided with a pair of mortise slots corresponding to the two tenons A on the main plate 200; the connection part between the crossbar part 301 and the front arch part 302 and the rear arch part 303 is processed into two pairs of tenons A, which correspond to a pair of mortise slots B on the main plate 200 and a pair of mortise slots B on the bottom plate 100, and the connection part between the two pairs of tenons A also serves as the tenon A corresponding to the mortise slot B of the arm 400; the front end of the front arch part 302 is processed into a tenon A corresponding to the mortise slot B at the front end of the bottom plate 100; the rear end of the rear arch part 303 is processed into a tenon A corresponding to the mortise slot B at the rear end of the top plate; a plurality of weight-reducing holes are processed on the main plate 200 and the bottom plate 100, and the whole presents a hollow structure; the fastener adopts a bolt connection.

[0026] It should be noted that the riveting assembly method strengthens the overall strength, reduces the number of fasteners, and reduces the weight of the machine body. At the same time, the mortise and tenon assembly method can independently disassemble the arm 400, which is convenient for replacement, reduces the difficulty of maintenance, and reduces the cost of blowing up the machine; when installing, the battery is installed on the main plate 200, considering the mortise and tenon assembly of the arm 400, the height of the crossbar part 301 is relatively low (for the insertion of the arm 400), the gap between the main plate 200 and the bottom plate 100 is small, and the area between the two can only be used for wiring. Such installation reduces the installation gravity center of the battery, so that the unmanned aerial vehicle responds faster when doing extreme actions; the cage structure formed between the front arch part 302 of the two side longitudinal beams 300 and the bottom plate 100 and between the rear arch part 303 of the two side longitudinal beams 300 and the main plate 200 facilitates the installation of electronic components and is safe and reliable; the assembly process is as shown in Figures 6-8 , and the assembly is carried out in order.

[0027] Further, the front arch part 302 of the two side longitudinal beams 300 is connected through the front connecting rod 500, and the rear arch part 303 of the two side longitudinal beams 300 is connected through the rear connecting rod 600.

[0028] It should be noted that the design of the front connecting rod 500 and the rear connecting rod 600 strengthens the overall strength, and also serves as a hinge seat for the reinforcing crossbar 700.

[0029] Further, the front connecting rod 500 and the rear connecting rod 600 are connected through the reinforcing crossbar 700, the reinforcing connecting rod is used to press the battery on the main plate 200, the front end of the reinforcing crossbar 700 is hingedly connected to the front connecting rod 500, the rear end of the reinforcing connecting rod is provided with a slot cooperating with the rear connecting rod 600, and the rear end of the reinforcing connecting rod is hingedly connected with a locking hook 701 for locking the rear connecting rod 600.

[0030] It should be noted that the reinforced crossbar 700 eliminates the operation of binding with a cable tie, and the battery replacement can be completed with one hand, and the pressure bar can effectively protect the battery body when the machine is exploded; the use process is: opening the lock hook 701, rotating the reinforced crossbar 700 around the front connecting rod 500, opening the battery compartment, putting in the battery, and then turning over the reinforced crossbar 700, so that the rear end of the reinforced crossbar 700 abuts against the rear connecting rod 600, and then rotating the lock hook 701 to hook the bottom of the rear connecting rod 600, to complete the fixation of the battery.

[0031] Further, the reinforced connecting rod is sleeved with a battery pressure pad 702.

[0032] It should be noted that the design of the battery pressure pad 702 can protect the surface of the battery.

[0033] The above embodiments are only used to help understand the method and its core idea of the utility model. It should be pointed out that for ordinary skilled persons in the art, without departing from the principles of the utility model, the utility model can be improved and modified in several ways, and these improvements and modifications also fall within the protection scope of the utility model claims.
