Description

Technical Field

[0001] This application relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a UAV pitot tube storage structure and a UAV. Background Technology

[0002] Existing drones are generally equipped with pitot tubes to measure the total pressure and static pressure of the airflow during drone flight in order to determine the gas velocity.

[0003] Pitot tubes are typically mounted on the nose of a drone, and in current technology, they are generally simply fixed to the drone. However, due to their length, pitot tubes are easily broken during packaging and transportation, and they also take up a considerable amount of packaging space.

[0004] Therefore, it is particularly important to provide a storage structure for the pitot tube of a drone that can be stored for easy packaging and transportation, as well as the drone itself. Utility Model Content

[0005] To address the aforementioned technical problems, this application provides a drone pitot tube storage structure and a drone.

[0006] According to the first aspect of this application, a storage structure for an unmanned aerial vehicle (UAV) pitot tube is proposed, comprising:

[0007] Pitot tube, the first end of which is connected to the UAV body via a mounting bracket;

[0008] A first flexible hose, the first end of which is connected to the first end of the airspeed tube, and the second end of which is connected to the UAV body;

[0009] The first end of the pitot tube is movably inserted into the fixed base, thus having a working position and a storage position. When the pitot tube is in the working position, the first end of the pitot tube is interference-fitted with the fixed base and is horizontal. When the pitot tube is in the storage position, the pitot tube is detached from the fixed base and bends downward.

[0010] Preferably, the first end of the airspeed tube is provided with a first limiting protrusion, and the first end of the first elastic hose is tightened and connected to the first limiting protrusion.

[0011] Preferably, the inner peripheral sidewall of the fixing seat is provided with a first guide slope, and the first limiting protrusion is provided with a first mating surface that mates with the first guide slope.

[0012] Preferably, a limiting boss is provided on the inner peripheral side wall of the fixed seat, and the airspeed tube is limited and engaged with the limiting boss.

[0013] Preferably, it also includes an adapter socket and an adapter pipe;

[0014] The adapter is used for fixed connection with the UAV body;

[0015] The first end of the adapter tube is inserted into the adapter seat, and the second end of the first elastic hose is connected to the first end of the adapter tube.

[0016] Preferably, the first end of the adapter tube is provided with a second limiting protrusion, and the second end of the second elastic hose is tightened and connected to the second limiting protrusion.

[0017] Preferably, a second guide slope is provided on the inner peripheral sidewall of the adapter, and a second mating surface that mates with the second guide slope is provided on the second limiting protrusion.

[0018] The first guide slope and the second guide slope have opposite inclination directions.

[0019] Preferably, it also includes a second flexible hose;

[0020] The first end of the second flexible hose is connected to the second end of the adapter tube, and the second end of the second flexible hose is used to connect to the airspeed tube plate on the UAV body.

[0021] Preferably, the second end of the adapter tube is provided with a third limiting protrusion, and the first end of the second elastic hose is tightened and connected to the third limiting protrusion.

[0022] According to a second aspect of this application, a drone is proposed, including the drone pitot tube housing structure as described above.

[0023] Compared with the prior art, the beneficial results of this application are as follows:

[0024] A first flexible hose is added to the pitot tube, and the pitot tube is fixed by a mounting bracket. When the drone is in use, the pitot tube is interference-fitted with the mounting bracket, and the pitot tube measures the gas flow rate in the working position. When the drone needs to be stored or packaged for transportation, the pitot tube is pulled outward, causing it to detach from the mounting bracket and be placed in the storage position by the elasticity of the first flexible hose. This allows the pitot tube to retract into the area close to the drone body, reducing the space occupied by the pitot tube itself and reducing the volume of the drone during storage or transportation.

[0043] In the following detailed description, reference is made to the accompanying drawings, which form part of the detailed description and illustrate illustrative specific embodiments in which the present application may be practiced. In this regard, directional terms such as “top,” “bottom,” “left,” “right,” “up,” “down,” etc., are used with reference to the orientation of the described figures. Because components of the embodiments can be positioned in several different orientations, directional terms are used for illustrative purposes and are by no means limiting. It should be understood that other embodiments may be utilized or logical changes may be made without departing from the scope of the present application. Therefore, the following detailed description should not be taken in a limiting sense, and the scope of the present application is defined by the appended claims.

[0044] According to a first aspect of this application, a pitot tube storage structure for a drone is proposed. The following description, in conjunction with the accompanying drawings, will illustrate an embodiment of the drone pitot tube storage structure of this application.

[0045] Reference Figure 1 and Figure 2 The UAV pitot tube storage structure 100 of this application includes: pitot tube 10, mounting base 20, and first flexible hose 30. The mounting base 20 has a hollow interior and a first connecting lug 21, which can be fixed to the UAV body by screws. The first end of the first flexible hose 30 is detachably connected to the first end of the pitot tube 10, and the second end of the first flexible hose 30 is connected to the UAV body. The first end of the pitot tube 10 is movably inserted into the mounting base 20 and can move the first flexible hose 30, while the second end of the pitot tube 10 moves away from the mounting base 20.

[0046] Therefore, the pitot tube 10 has both a working position and a storage position when installed on the UAV body. Specifically, the first end of the pitot tube 10 is horizontally inserted into the mounting base 20, with an interference fit between them. At this time, the pitot tube 10 is in the working position, which can measure the gas flow rate during UAV flight. When the second end of the pitot tube 10 is pulled, the first end of the pitot tube 10 causes the first elastic hose 30 to detach from the mounting base 20 and bend downwards due to the elasticity of the first elastic hose 30. At this time, the pitot tube 10 is in the storage position, retracting to the area close to the UAV body. This reduces the space occupied by the pitot tube 10 itself and lowers the volume of the UAV during storage or transportation.

[0047] In this embodiment, the first elastic hose 30 is made of rubber.

[0048] Reference Figure 3 and Figure 4 In one specific embodiment, the first end of the airspeed tube 10 is provided with a first limiting protrusion 11. When the first end of the first elastic hose 30 is inserted into the first end of the airspeed tube 10, the first end of the first elastic hose 30 is tightened to the first limiting protrusion 11, so that the first elastic hose 30 will not detach from the airspeed tube 10 when it is pulled by the airspeed tube 10.

[0049] In one specific embodiment, a first guide slope 22 is provided on the inner peripheral sidewall of the fixing base 20, and a first mating surface 111 that mates with the first guide slope 22 is provided on the outer peripheral surface of the first limiting protrusion 11. When the airspeed tube 10 is inserted into the fixing base 20, the first guide slope 22 and the first mating surface 111 mate with each other, and the airspeed tube 10 can be more stably fixed in the fixing base 20.

[0050] In one specific embodiment, a limiting boss 23 is provided on the inner peripheral sidewall of the mounting base 20, and the pitot tube 10 is limited and engaged with the limiting boss 23. When the pitot tube 10 is inserted into the mounting base 20, when the pitot tube 10 abuts against the limiting boss 23, it indicates that it has been installed in place. This also prevents the operator from continuing to use brute force to insert the pitot tube 10, which could damage the structure of the pitot tube 10.

[0051] Since the pitot tube 10 needs to be electrically connected to the pitot tube board (i.e., circuit board, not shown in the figure) on the drone body, wiring is required inside the pitot tube 10 and the first flexible hose 30. If the second end of the first flexible hose 30 is directly connected to the pitot tube board, when the drone needs to be packaged and transported, during the process of pulling the pitot tube 10 to store it, on the one hand, the second end of the first flexible hose 30 can easily detach from the pitot tube board, affecting the wiring or exposing the wires; on the other hand, the first flexible hose 30 can easily cause vibration on the pitot tube board, damaging other electronic components on the pitot tube board.

[0052] Therefore, refer to Figure 5 The UAV pitot tube storage structure 100 of this application further includes: an adapter 40, an adapter tube 50, and a second flexible hose 60. The adapter 40 has a hollow interior and a second connecting ear 41, which can be fixed to the UAV body with screws. The first end of the adapter tube 50 is connected to the second end of the first flexible hose 30, and the first end of the adapter tube 50 is detachably inserted into the adapter 40. The first end of the second flexible hose 60 is connected to the second end of the adapter tube 50, and the second end of the second flexible hose 60 is used to connect to the pitot tube plate on the UAV body.

[0053] Therefore, when the drone needs to be packaged and transported, during the process of pulling the pitot tube 10 to store it, the first end of the first flexible hose 30 is pulled along with the pitot tube 10, but the second end of the first flexible hose 30 is fixed in the adapter 40 by the adapter tube 50 and will not detach. By adding a second flexible hose 60 to connect to the pitot tube plate, during the process of pulling the pitot tube 10, only the pitot tube 10 and the first flexible hose 30 are subjected to force, while the second flexible hose 60 is not subjected to force and will not be affected, thus not affecting the pitot tube plate.

[0054] In this embodiment, the second flexible hose 60 is also made of rubber.

[0055] In one specific embodiment, the first end of the adapter 50 is provided with a second limiting protrusion 51. When the second end of the first elastic hose 30 is inserted into the first end of the adapter 50, the second end of the first elastic hose 30 is tightened to the second limiting protrusion 51, so that the first elastic hose 30 will not detach from the adapter 50 when it is pulled by the airspeed tube 10.

[0056] In one specific embodiment, a second guide slope 42 is provided on the inner peripheral sidewall of the adapter 40, and a second mating surface 511 that mates with the second guide slope 42 is provided on the outer peripheral surface of the second limiting protrusion 51. The first guide slope 22 and the second guide slope 42 have opposite inclination directions. With this structure, the adapter tube 50 is more stably inserted into the adapter 40, and the first elastic hose 30 will not easily detach from the adapter tube 50 when pulled by the pneumatic tube 10.

[0057] In one specific embodiment, the second end of the adapter 50 is provided with a third limiting protrusion 52. When the first end of the second elastic hose 60 is inserted into the second end of the adapter 50, the first end of the second elastic hose 60 is tightened to the third limiting protrusion 52, thereby achieving a detachable connection.

[0058] In summary, the UAV pitot tube storage structure 100 proposed in this application achieves the following beneficial effects:

[0059] A first flexible hose 30 is added to the pitot tube 10, and the pitot tube 10 is fixed by the mounting base 20. When the drone is in operation, the pitot tube 10 is made to be interference-fitted with the mounting base 20. The pitot tube 10 measures the gas flow rate in the working position. When the drone needs to be stored or packaged for transportation, the pitot tube 10 is pulled outward, so that the pitot tube 10 is detached from the mounting base 20 and is placed in the storage position under the action of the first flexible hose 30. This allows the pitot tube 10 to be retracted to the area close to the drone body, reducing the space occupied by the pitot tube 10 itself and reducing the volume of the drone during storage or transportation.

[0060] Furthermore, the second end of the first flexible hose 30 is fixed by the adapter 40 and the adapter tube 50, ensuring that the first flexible hose 30 will not detach from the adapter tube 50 when pulled by the pitot tube 10. Additionally, by adding a connection between the second flexible hose 60 and the pitot tube sheet, only the pitot tube 10 and the first flexible hose 30 are subjected to force during the pulling of the pitot tube 10; the second flexible hose 60 is not subjected to force and will not be affected, thus preventing any impact on the pitot tube sheet.

[0061] According to a second aspect of this application, an unmanned aerial vehicle (UAV) is also proposed.

[0062] Reference Figure 6 and Figure 7 The drone 1000 of this application includes: a drone body 200 and a drone pitot tube storage structure 100 as described in the first aspect. When the pitot tube 10 is in the working position, the pitot tube 10 is parallel to the drone body 200. When the pitot tube 10 is in the storage position, the pitot tube 10 is bent downward and close to the drone body 200.

[0063] In one specific embodiment, the UAV pitot tube housing structure 100 is disposed at the nose of the UAV 1000.

[0064] It is obvious that those skilled in the art can make various modifications and alterations to the embodiments of this application without departing from the spirit and scope of this application. In this way, this application also aims to cover such modifications and alterations if they fall within the scope of the claims and their equivalents. The word "comprising" does not exclude the presence of other elements or steps not listed in the claims. The simple fact that certain measures are described in mutually different dependent claims does not indicate that a combination of these measures cannot be used for profit. Any reference numerals in the claims should not be considered limiting in scope.
