Description

Technical Field

[0001] This application relates to the field of drone accessory technology, and in particular to a portable and storable drone propeller. Background Technology

[0002] Most existing civilian drones use propellers to provide lift. However, because propellers are relatively large, they take up a lot of storage space. Moreover, the long blades are prone to bending or even breaking under stress in the storage box. Current technologies often use foam cushioning material with a matching shape in the storage box, which takes up even more space and makes storage inconvenient. Summary of the Invention

[0003] The purpose of this application is to provide a portable drone propeller that is easy to store.

[0004] To achieve the above objectives, this application provides a portable and retractable drone propeller: including a wing mount, the bottom surface of which has an end sleeve adapted to connect to the rotation drive output end of the drone, the top of which has a pair of mounting plates, a configuration slot formed between the two mounting plates, a pair of blades movably connected to the wing mount within the configuration slot, and a pair of clearance slots located between the two mounting plates on the side of the wing mount, adapted to engage with the blades when the blades are parallel to the axis of the end sleeve, so that the retracted blades are in a vertical direction and do not occupy additional horizontal space.

[0005] As a preferred embodiment, a pair of constraint members are connected between the two mounting plates. The main body of the constraint member is an optical axis portion, and one end of the blade has a hook portion. The inner wall of the hook portion is an arc groove, which is suitable for engaging with the optical axis portion to form a rotating pair. The top surface of the blade has a counter-vertical semi-cone located above the hook portion, which is suitable for forming a complete cone with the counter-vertical semi-cone above another parallel blade, preventing the two blades from continuing to tilt upwards.

[0006] As a preferred embodiment, the area between the arc groove of the hook portion and the outer side is a smooth surface. The smooth surface is close to the lower surface of the blade and parallel to the extension direction of the blade, which facilitates the assembly and disassembly of the blade.

[0007] As a preferred embodiment, the two mounting plates are symmetrical to each other, with their opposite sides parallel and adapted to contact the sides of the blades, thereby suppressing blade sway and ensuring the stability of the blades after deployment.

[0008] As a preferred embodiment, each of the mounting plates has two through holes, and the two ends of the optical axis are adapted to be inserted into the two aligned through holes of the mounting plates respectively, thereby restricting the degree of freedom of the optical axis.

[0009] As a preferred embodiment, the outer side of the mounting plate is also provided with a countersunk groove communicating with the through hole, and the two ends of the optical axis are fixedly connected with limit rings, which are suitable for sinking into the countersunk groove to improve the insertion stability of the optical axis in the through hole.

[0010] As a preferred embodiment, the bottom surface of the end sleeve is provided with a pin hole, which is suitable for interference fitting with the output end of the UAV rotation drive, taking into account both ease of disassembly and assembly and connection stability.

[0011] As a preferred embodiment, the wing mount and rotor blades are made of plastic, while the optical axis and limiting ring are made of corrosion-resistant alloy material, thus balancing lightweight and structural stability.

[0012] Compared with the prior art, the beneficial effects of this application are as follows:

[0013] (1) By designing a constraint structure and opening a clearance groove structure on the side of the wing seat, the blades can rotate and change in the horizontal and vertical directions. When stored, the vertical storage space can be utilized. The retracted blades can be close to the cantilever of the UAV, which not only reduces the space occupied in the horizontal direction and reduces the probability of the blades being subjected to force, but also improves the stability of storage.

[0014] (2) By designing a hook at the end of the blade, the blade can be disassembled and overloaded more conveniently. By setting a top-to-top semi-cone structure above the hook, the two blades can abut against each other to maintain stability after being unfolded. Attached Figure Description

[0023] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this application.

[0025] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0026] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0027] like Figure 1-7 The portable and retractable drone propeller shown includes a wing mount 1 molded from a single piece of plastic. The bottom surface of the wing mount 1 has an end sleeve 101 for connecting to the rotary drive output end of the drone. Typically, an upwardly extending pin hole 102 is formed on the bottom surface of the end sleeve 101, which fits precisely with the output end of the drone's rotary drive. Due to the high contact friction between plastic and metal, and the fact that the rotary drive output end and the pin hole 102 are not circular, the rotary drive can stably provide rotational torque to the wing mount 1.

[0028] The top of the wing mount 1 has a pair of symmetrical mounting plates 103, with a mounting groove 104 formed between the two mounting plates 103. A pair of blades 2 are movably connected to the wing mount 1 within the mounting groove 104. The blades 2 are also integrally molded from plastic. A pair of constraint members 3 are connected between the two mounting plates 103. The two constraint members 3 are of the same specification, and their main body is an optical axis portion 301. The axes of the two optical axis portions 301 are parallel. One end of the blade 2 has a hook portion 201, the inner wall of which is a circular arc groove 203 for engaging with the optical axis portion 301 to form a rotating pair. The top surface of the blade 2 has a section located at the hook portion 201. The opposing semi-cone 202 above 01 can form a complete cone with the opposing semi-cone 202 above another parallel blade 2. The two opposing semi-cones 202 abut against each other, which can prevent the end of the blade 2 away from the optical axis 301 from continuing to tilt upward. The arc groove 203 of the hook part 201 and the outer side are connected by a smooth surface 204, which can be made at a position tangent to the lowest point of the arc groove 203. The smooth surface 204 is close to the lower surface of the blade 2 and parallel to the extension direction of the blade 2. When the blade 2 rotates to be parallel to the axis of the end sleeve 101, the optical axis 301 can slide out from the arc groove 203 along the smooth surface 204.

[0029] The two mounting plates 103 have parallel sides that can contact the sides of the blade 2, thereby suppressing the blade 2 from moving along the axis of the optical shaft 301. Each mounting plate 103 has two through holes 105, and the positions of the through holes 105 on the two mounting plates 103 are corresponding. The two ends of the optical shaft 301 are inserted into the aligned through holes 105 of the two mounting plates 103 respectively. The outer side of the mounting plate 103 also has a countersunk groove 106 communicating with the through holes 105. The two ends of each optical shaft 301 are fixedly connected to a limiting ring 302, which is recessed into the countersunk groove 106, which can improve the flatness of the outer side of the mounting plate 103, thereby reducing the ineffective wind resistance when the propeller rotates. The optical shaft 301 and the limiting ring 302 are actually separate parts, which are screwed together by a threaded structure. However, both are made of corrosion-resistant alloy material, so that the optical shaft 301 is not easily deformed and can well ensure the connection stability of the blade 2 on the wing mount 1.

[0030] The side of the wing mount 1 has a pair of clearance slots 107 located between the two mounting plates 103. These slots can engage with the blades 2 when the blades 2 are parallel to the axis of the end sleeve 101. This allows the two blades 2 to be retracted in a direction that is parallel to the axis of the end sleeve 101 and clamped on the outside of the UAV cantilever configured with rotation drive, thereby limiting the continued rotation of the propeller and facilitating the storage process.

[0031] Installation method: First, assemble the propeller. Insert the optical shaft 301 into the through holes 105 of the two mounting plates 103, then secure it with the limiting ring 302. Next, position the hook portion 201 of the blade 2 upwards, with the main body of the blade 2 against the relief groove 107 and slide downwards, allowing the optical shaft 301 to slide along the smooth surface 204 into the arc groove 203. The other blade 2 is then engaged with the other optical shaft 301 in the same manner. Finally, simultaneously rotate both blades 2 upwards around their respective optical shafts 301 in a direction away from each other until both... The top half-cones 202 abut against each other, at which point the extension directions of the two blades 2 are parallel. Then, the end sleeve 101 at the bottom of the assembled propeller can be put on the output end of the drone arm rotation drive. When the drone is finished and needs to be stored, downward pressure is applied to the two blades 2 at the same time, causing the two blades 2 to rotate downward around their respective optical axis 301 until they are parallel to the axis of the end sleeve 101 again and clamp the drone arm. At this time, the propeller is restricted by the drone arm and can no longer rotate, which not only reduces the storage space but also improves the storage stability.
