Description
Technical Field
[0001] The utility model relates to the technical field of unmanned aerial vehicles, and particularly relates to a protective cover and an unmanned aerial vehicle.
Background Art
[0002] With the development of technology and the low-altitude economy, unmanned aerial vehicles are more widely used in various industries. Unmanned aerial vehicles have gradually been applied to various industries such as logistics, transportation, and warfare from traditional limited scenarios such as test aircraft and reconnaissance aircraft.
[0003] Most of the existing unmanned aerial vehicles are operated manually by remote control. During the operation process, due to human operation errors or changes in signal strength, the unmanned aerial vehicle may crash, resulting in damage to the unmanned aerial vehicle. Secondly, during the transportation process of the unmanned aerial vehicle, compared with traditional aircraft, its structure is more precise, the fuselage is more compact, and the structural strength of the entire fuselage is not as strong as that of traditional aircraft. Therefore, during the transportation process, it is easy to cause damage to the fuselage under the action of external forces, affecting subsequent use.
[0004] Based on this, it is necessary to provide a protective cover and an unmanned aerial vehicle that can protect the rotors and fuselage of the unmanned aerial vehicle, and the protective cover can be conveniently disassembled at any time to meet different flight requirements. At the same time, based on the flight needs and actual use environment of the unmanned aerial vehicle, this kind of protective cover should also not affect the normal flight process of the unmanned aerial vehicle as much as possible, with small consumables and low cost.
Content of the Utility Model
[0005] In view of the above technical problems in the prior art, the utility model provides a protective cover, which includes: a circular rod;
[0006] A support rod, which is detachably connected to the circular rod;
[0007] A first installation part, which is detachably connected to the support rod;
[0008] One end of the support rod is connected to the circular rod, and the other end of the support rod is connected to the first installation part; the first installation part is provided with an installation groove, the installation groove is semi-open, and the first installation part clamps the fuselage through the installation groove.
[0009] It should be noted that the first mounting part and the fuselage are detachably connected. It can be clamped on the fuselage. If it is necessary to separate the protective cover and the fuselage, the first mounting part can be directly removed from the fuselage; the first mounting part can also be connected to the fuselage and the protective cover in a magnetic adsorption manner. In the application, the specific structure of the first mounting part is not limited. As long as the structure realizes the detachable connection between the fuselage and the first mounting part, it is within the protection scope of this application.
[0010] By designing the first mounting part between the fuselage and the protective cover in this application, on the premise of realizing detachable connection, the appearance structure or internal structure of the fuselage and the protective cover is not damaged, protecting the integrity of the fuselage and the protective cover, which is beneficial for the drone to maintain good flight performance during flight and better meet the requirements of aerodynamics.
[0011] Preferably, the shape of the installation groove is a semi-open U-shaped groove.
[0012] Specifically, the first mounting part can be a U-shaped groove. The U-shaped groove includes an inner side wall, and a recessed groove is provided on the inner side wall. The recessed groove and the fuselage are engaged with each other, and the recessed groove penetrates the surface of the inner side wall of the installation groove.
[0013] It should be noted that the recessed groove and the fuselage are relatively fixed through a concave-convex engagement method, making it difficult for the fuselage and the protective cover to fall off from each other, so that the protective cover can play a role in protecting the propeller blades.
[0014] Specifically, the first mounting part includes a mounting hole, and the mounting hole is designed corresponding to the support rod, and the support rod is inserted into the mounting hole.
[0015] Specifically, the first mounting part includes a hook, and the hook is provided on the outer side wall surface of the installation groove.
[0016] Specifically, the protective cover further includes an elastic member, the elastic member is hung on the hook, and the fuselage is accommodated in the accommodation space surrounded by the elastic member and the installation groove.
[0017] Preferably, the elastic member can be an elastic member such as rubber, silica gel, or spring.
[0018] It should be noted that the mounting hole is installed on the outer side wall of the U-shaped groove.
[0019] It should be noted that the first mounting portion is used to connect the support rod and the fuselage. Among them, the U-shaped groove clamps the fuselage, the mounting hole is used to insert the support rod, and the hook is used to connect with the elastic member. Further, the elastic member and the U-shaped groove fix the fuselage. During actual use, the operator only needs to remove the elastic member from the hook, and then separate the fuselage from the U-shaped groove, so as to realize the separation of the fuselage and the protective cover. This operation method is simple and efficient, not easy to make mistakes, and at the same time, it is not easy to damage the fuselage during the operation.
[0020] Specifically, the protective cover further includes: a second mounting portion, which is mounted between the annular rod and the support rod. The second mounting portion includes:
[0021] A transverse connection end;
[0022] A longitudinal connection end, which is integrally designed with the transverse connection end; wherein the transverse connection end engages with the annular rod, and the longitudinal connection end engages with the support rod.
[0023] Preferably, the longitudinal connection end and the transverse connection end are both provided with mounting holes, and both the annular rod and the support rod can be inserted into the mounting holes.
[0024] It should be noted that the second mounting portion and the annular rod can be detachably connected or integrally designed. The support rod provides a supporting force for the annular rod and fixes the positions of the annular rod and the fuselage.
[0025] Preferably, the second mounting portion and the annular rod are detachably connected, so that the annular rod and the support rod can be disassembled.
[0026] Specifically, the material of the annular rod and / or the support rod is carbon fiber material.
[0027] Preferably, the material of the first mounting portion and / or the second mounting portion is plastic material.
[0028] It should be noted that by setting the material of the annular rod and / or the support rod to be a carbon fiber material with a relatively light weight and a relatively hard material, and setting the material of the first mounting portion and / or the second mounting portion to be plastic material, the overall protective cover reduces the cost without losing the strength requirements.
[0029] Preferably, the support rod is a telescopic rod.
[0030] It should be noted that when the support rod is a telescopic rod, the overall shape and structure of the protective cover can be further accommodated, facilitating the reduction of its volume and making it convenient to carry and install.
[0031] Preferably, the number of the support rods and the curved rods of the annular rod is greater than or equal to two.
[0032] Specifically, the annular rod encloses a protection area that extends from the head of the fuselage to the tail of the fuselage. The cross-sectional width of the protection area first increases and then decreases, and the distance by which the width of the protection area increases is less than the distance by which the width of the protection area decreases.
[0033] Preferably, extending from the head of the fuselage to the tail of the fuselage, the shape of the protective cover is in the shape of a light bulb or a water droplet. The shape of the water droplet or the light bulb here is not regarded as a limitation on the shape of the protective cover.
[0034] It should be noted that from an overlooking perspective, the overall outer shape of the protective cover meets the requirements of aerodynamics. Under this design, the resistance encountered by the drone during flight can be minimized as much as possible.

[0035] Specifically, the annular rod includes a plurality of curved rods, and the plurality of curved rods are assembled and connected at the second installation part to form the annular rod.
[0036] Preferably, the protective cover further includes a housing that covers the annular rod. The annular rod and the housing together enclose a semi-enclosed receiving space with an edge, and the fuselage and the propeller blades are received in the semi-enclosed receiving space.
[0037] It should be noted that due to the different environments in which the drone is used, especially during outdoor use, in order to facilitate the storage and preservation of the drone, a housing is provided on the protective cover to function as waterproofing and rainproofing for the drone.
[0038] The present utility model further provides a drone, which includes: the fuselage; propeller blades that are arranged above the fuselage and are detachably connected to the fuselage; and the protective cover that is arranged outside the fuselage and the propeller blades.
[0039] By providing a protective cover for the drone, while meeting the flight requirements of the drone, it is protected, and first, the protection function is realized. On this basis, the protective cover can achieve a quick-release structure and reduce the cost of the protective cover while meeting the strength requirements.
