Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, and in particular to an integrated composite material unmanned aerial vehicle front equipment cabin structure. Background Art

[0002] The key to drones is the onboard equipment they carry, which can help them achieve various control functions. Usually, drones will have onboard equipment arranged in the nose cover, front equipment compartment and rear equipment compartment, the middle part is used to install the fuel tank, and the tail cover is used to install the engine.

[0003] At present, most UAVs install the equipment mounting plate in the front equipment compartment after the skin is installed. Some configurations also bond a composite material flat plate in the equipment compartment to serve as a support for many airborne equipment. The airborne equipment of the flight control generally has strict installation requirements and needs to ensure its levelness. The bracket installed by fasteners needs to be ensured by the jig to ensure the levelness. In addition to the difficulty in ensuring the levelness, the composite material flat plate bonded afterwards also has the problems of limited operating space and long bonding curing time. At the same time, the front equipment compartment is usually the process separation surface with the UAV nose cover, and generally a metal frame is required to connect the nose cover and the front equipment compartment. The UAV needs to ensure that the outer surface is smooth. The nose cover and the front equipment compartment need to be manufactured using a negative mold, so the quality of the inner surface cannot be guaranteed, and it is difficult to match when connecting with the metal frame, and a large assembly gap needs to be left. Utility Model Content

[0004] The purpose of the utility model is to design an integrated composite material UAV front equipment cabin structure to solve the problem that it is difficult to ensure the horizontality of the existing UAV front equipment cabin when the equipment mounting plate or the composite material flat plate is installed later, and the problem that the existing front equipment cabin is difficult to assemble with the metal frame, thereby solving the above problems.

[0005] In order to achieve the above object, the utility model is realized by the following technical solutions:

[0006] The utility model designs an integrated composite material UAV front equipment cabin structure, which includes:

[0007] A front equipment compartment having a front end surface and a rear end surface opposite to each other, wherein the rear end surface is used to connect with the fuselage structure of the UAV;

[0008] A nose cover connection structure, which is connected to the front end surface, and the nose cover connection structure is sunken relative to the front end surface, and the nose cover connection structure is used to connect to the nose cover of the drone;

[0009] An equipment installation plate is arranged near the lower part of the front equipment compartment so that there is installation space for airborne equipment above and below the equipment installation plate;

[0010] An upper maintenance cover, which is arranged on the upper part of the front equipment compartment;

[0011] And a dimensional cover, which is arranged below the exterior of the front equipment compartment and is used to maintain the body shape of the front equipment compartment.

[0012] Specifically, in order to ensure the integrated molding of the front equipment compartment, a combination mold of a heat shrinkable core mold + a metal outer mold is selected. After the prepreg is laid on the surface of the heat shrinkable core mold, it is placed in the metal outer mold for curing and molding, and the curing pressure is provided by inflating the heat shrinkable core mold.

[0013] Furthermore, an integrated composite material UAV front equipment compartment structure: the nose cover connection structure is integrally formed with the front end face.

[0014] Furthermore, an integrated composite material UAV front equipment compartment structure: the equipment mounting plate and the front equipment compartment are integrally formed.

[0015] Furthermore, an integrated composite material UAV front equipment compartment structure: the equipment mounting plate is locally thickened according to the installation position of the airborne equipment to install more airborne equipment.

[0016] Furthermore, an integrated composite material UAV front equipment cabin structure: an equipment avoidance zone is set on the equipment mounting plate according to the installation position of the airborne equipment, so as to be used for installing more airborne equipment.

[0017] Furthermore, an integrated composite material UAV front equipment compartment structure: the front equipment compartment structure also includes a lower maintenance cover, which is arranged on the dimensional cover.

[0018] Furthermore, an integrated composite material UAV front equipment compartment structure: the nose cover connecting structure is provided with reinforcing ribs for increasing the structural strength of the nose cover connecting structure.

[0019] Beneficial effects of the utility model:

[0020] (1) The front equipment compartment structure designed by the present invention integrates the front equipment compartment and the equipment mounting plate into one piece, thereby eliminating the installation process of the equipment mounting plate. The equipment mounting plate is integrally formed to ensure its horizontality. The integrated forming also avoids the problems of limited operating space and long bonding curing time when bonding the composite material plate in the front equipment compartment at a later stage.

[0021] (2) In the present invention, the dimensional cover is arranged on the outside of the front equipment compartment. Before the dimensional cover is installed, the space below the front equipment compartment is completely open, and there is sufficient installation space, so that the support plate nuts required for the installation of the airborne equipment can be installed on the equipment installation plate in advance.

[0022] (3) The front equipment compartment structure designed by the utility model can reduce the installation work of the front equipment compartment and the I-shaped metal frame by setting a sunken nose cover connection structure on the front end surface of the front equipment compartment and using it as the connection area with the drone nose cover. The existing method is to connect the nose cover and the front equipment compartment through an I-shaped metal frame, but this application does not need it.

[0023] (4) The outer surface of the front equipment compartment of the utility model is a mold surface, which has good surface quality and can ensure its accuracy, and is used to connect the nose cover of the drone. The airborne equipment can be installed above and below the equipment mounting plate, so that the utilization rate of the equipment mounting plate is high and there is an installation passage.

[0024] (5) The utility model sets partial reinforcing ribs on the nose cover connection structure, and at the same time retains a certain opening in the nose cover connection structure, which can improve the structural rigidity. The opening retained on the nose cover connection structure can also be used for equipment transfer during the installation of airborne equipment, and the reinforcing ribs can also be used for the installation of small equipment.

[0031] Example 1

[0032] like Figures 1-2 As shown, this embodiment 1 designs an integrated composite material UAV front equipment cabin structure, and the front equipment cabin structure includes:

[0033] A front equipment compartment 1 having a front face 11 and a rear face 12 opposite to each other, wherein the rear face 12 is used to connect to the fuselage structure of the drone;

[0034] A nose cover connecting structure 2, which is connected to the front end face 11, and the nose cover connecting structure 2 and the front equipment compartment 1 are integrally formed, the nose cover connecting structure 2 is sunken relative to the front end face 11, and a reinforcing rib 21 is further provided on the nose cover connecting structure 2, the nose cover connecting structure 2 is used to connect to the nose cover of the drone, and the reinforcing rib 21 is used to increase the structural strength of the nose cover connecting structure 2;

[0035] An equipment installation plate 3 is arranged near the lower part of the front equipment compartment 1 so that there is installation space for airborne equipment above and below the equipment installation plate 3. The equipment installation plate 3 and the front equipment compartment 1 are integrally formed, and an equipment avoidance area 31 can be arranged on the equipment installation plate 3 according to the installation position of the airborne equipment, so as to be used for installing more airborne equipment;

[0036] An upper maintenance cover 4, which is arranged on the upper part of the front equipment compartment 1;

[0037] A dimensional cover 5, which is arranged at the lower part of the front equipment compartment 1 and is used to maintain the body shape of the front equipment compartment 1, but it does not participate in the transmission of the main load;

[0038] And a lower maintenance cover 6, which is arranged on the dimensional cover 5.

[0039] Specifically, in order to ensure that the front equipment compartment 1 of the integrated composite material UAV is formed in one piece, it is necessary to use a combination mold of a heat shrinkable core mold + a metal outer mold. After the prepreg is laid on the surface of the heat shrinkable core mold, it is placed in the metal outer mold for curing and molding (to ensure good surface quality and high precision, and can be used to connect the nose cover), and the curing pressure is provided by inflating the heat shrinkable core mold.

[0040] The device mounting plate 3 in the utility model has designability, and can be partially thickened or designed with corresponding device avoidance areas according to the installation position of the airborne equipment, so that as many airborne equipment as possible can be installed on the device mounting plate 3. When installing the airborne equipment, the support plate nut needs to be installed on the device mounting plate 3 in advance. Before the dimensional cover 5 is installed, the space below the device mounting plate 3 is completely open, and there is sufficient installation space.

[0041] An upper maintenance cover 4 is installed on the upper part of the front equipment compartment 1 by means of screws and support plate nuts. The maintenance cover 4 can be opened to connect the airborne equipment or to connect equipment on the cover.

[0042] Equipment can be installed above and below the equipment mounting plate 3, and there are sufficient installation passages. The space below the equipment mounting plate 3 is relatively small, and relatively flat airborne equipment can be arranged. A corresponding lower maintenance cover 6 can also be arranged on the dimensional cover 5. The dimensional cover 5 is relatively thin and is used to maintain the shape of the body. It does not participate in the main load transfer.

[0043] The front end face 11 of the front equipment compartment 1 is designed to be sunken to form a nose cover connection structure 2 for connecting the nose cover of the drone. Since the outer surface of the front equipment compartment 1 is formed by a metal mold, its surface quality is good and the molding accuracy is high. At the same time, reinforcing ribs 21 are designed on the nose cover connection structure 2 of the front equipment compartment 1, thereby forming a structure with a certain opening. On the one hand, the rigidity of the overall structure is improved, and on the other hand, the opening part can be used to insert the airborne equipment into the front equipment compartment 1. At the same time, the retained reinforcing ribs 21 can also be used to install small equipment such as wiring boards.

[0044] The above preferred embodiments of the utility model are only used to explain the utility model, and are not used to limit the utility model. Any obvious changes or modifications derived from the technical solution of the utility model are still within the protection scope of the utility model.
