Description

Technical Field

[0001] This utility model relates to the field of toy airplane technology, and in particular to a propeller protection device for a remote-controlled toy airplane. Background Technology

[0002] A remote-controlled toy airplane is a small aircraft primarily intended for entertainment. Its flight is controlled via a radio remote control system. The fuselage (body) is the main structure of a remote-controlled toy airplane, usually made of lightweight materials such as plastic, carbon fiber, or foam. It supports other components of the aircraft, such as the power system, control system, and landing gear. The shape and design of the fuselage vary depending on the type of aircraft (such as fixed-wing, helicopter, or multi-rotor). Its design aims to minimize weight while ensuring strength to facilitate flight.

[0003] Users can remotely control toy airplanes using a corresponding remote control to achieve the corresponding movements. However, when the remote-controlled toy airplanes are not in use, if the propellers are not protected, they are easily damaged by external factors. For example, when the toy airplane is placed in a storage box or cabinet, the propellers, being relatively long and large, are easily squeezed or collided with other items. Squeezing and collisions may cause the propellers to crack, deform, or break. Once the propellers are damaged, it will directly affect the flight performance of the airplane, resulting in uneven power output during flight, increased vibration of the airplane, or even failure to take off normally. Therefore, a propeller protection device for remote-controlled toy airplanes is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a propeller protection device for remote-controlled toy airplanes, which aims to improve the problem that the propellers in the prior art are large and easily damaged by collisions and squeezing with other objects.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a propeller protection device for a remote-controlled toy airplane, comprising a body, a support column fixedly connected to the right end of the body, a rotating column rotatably connected to the inner wall of the support column, and a protection mechanism provided on the outer arc surface of the support column.

[0006] The protective mechanism includes a rotating plate, with a storage base and a fixing base fixedly connected to the right end of the rotating plate. The inner wall of the storage base is elastically connected to a positioning pin via a connecting spring. A support plate is fixedly connected to the top of the rotating column, and a propeller is rotatably connected to the top of the support plate. A fixing member is provided at the right end of the propeller, and a synchronization mechanism is provided on the outer arc surface of the support column.

[0007] As a further description of the above technical solution:

[0008] One end of the connecting spring is fixedly connected to the outer wall of the positioning pin, and the other end of the connecting spring is fixedly connected to the upper side wall of the storage base. The outer wall of the positioning pin is slidably connected to the inner wall of the storage base.

[0009] As a further description of the above technical solution:

[0010] The bottom end of the positioning pin is inserted into the inner wall of the top of the support column, and the inner side wall of the rotating plate is rotatably connected to the outer arc surface of the support column.

[0011] As a further description of the above technical solution:

[0012] The inner walls of the storage base and the fixing base are provided with receiving grooves that can accommodate the propeller, and the rear end of the support column is provided with a connecting groove that can be inserted into the bottom end of the positioning pin.

[0013] As a further description of the above technical solution:

[0014] The fastener includes a bolt, the outer wall of which is threaded onto the inner wall of the propeller.

[0015] As a further description of the above technical solution:

[0016] The bottom end of the bolt is threaded onto the inner wall of the support plate.

[0017] As a further description of the above technical solution:

[0018] The synchronization mechanism includes a rotating ring, the inner sidewall of which is rotatably and slidably connected to the outer arc surface of the support column, and a connecting plate rotatably connected to the outer wall of the rotating ring, the side of which is away from the rotating ring being rotatably connected to the outer wall of the propeller.

[0019] This utility model has the following beneficial effects:

[0020] 1. In this utility model, through the cooperation between the structure of the machine body and its protective mechanism, the propeller can be flipped to a horizontal state when not in use. Then, the rotating plate is rotated so that the storage seat and its fixing seat protect the propeller, thereby reducing the contact between the propeller and other items, and thus making the overall service life longer.

[0021] 2. In this utility model, through the cooperation between the structure such as the synchronization mechanism, when it is necessary to store the propeller, the movement of the rotating ring can drive the movement of multiple sets of connecting plates, thereby enabling the synchronous storage of multiple sets of propellers. The operation is simple and convenient. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1 The present invention provides an embodiment of a propeller protection device for a remote-controlled toy airplane, comprising a body 1, a support column 2 fixedly connected to the right end of the body 1, a rotating column 3 rotatably connected to the inner wall of the support column 2, the body 1 being a remote-controlled toy airplane, and corresponding electronic control components provided on the inner walls of the support column 2 and the rotating column 3 to enable the rotating column 3 to rotate, and a protection mechanism 4 provided on the outer arc surface of the support column 2; the protection mechanism 4 can provide corresponding protection for the propeller 6.

[0031] Reference Figures 2-4The protective mechanism 4 includes a rotating plate 401. A storage seat 402 and a fixing seat 405 are fixedly connected to the right end of the rotating plate 401. The rotating plate 401 is circular, and there are multiple sets of fixing seats 405, while there is only one set of storage seats 402. The inner wall of the storage seat 402 is elastically connected to a positioning pin 404 through a connecting spring 403. The positioning pin 404 can play a limiting and fixing role. A support plate 408 is fixedly connected to the top of the rotating column 3. A propeller 6 is rotatably connected to the top of the support plate 408. The number of support plates 408 and propellers 6 is the same, and the propellers 6 can rotate, thereby protecting them. A fixing member is provided at the right end of the propeller 6. The fixing member can support and fix the propeller 6 when it is unfolded into a vertical state. A synchronization mechanism 5 is provided on the outer arc surface of the support column 2. The synchronization mechanism 5 can make multiple sets of propellers 6 rotate synchronously.

[0032] Reference Figures 3-5 One end of the connecting spring 403 is fixedly connected to the outer wall of the positioning pin 404, and the other end of the connecting spring 403 is fixedly connected to the upper side wall of the storage base 402. The outer wall of the positioning pin 404 is slidably connected to the inner wall of the storage base 402. The elasticity of the connecting spring 403 enables the positioning pin 404 to have the functions of reset and limit. The bottom end of the positioning pin 404 is inserted into the top inner wall of the support column 2. The two are inserted to complete the corresponding limit operation. The inner side wall of the rotating plate 401 is rotatably connected to the outer arc surface of the support column 2. The rotation setting facilitates the storage and protection of the propeller 6. The inner walls of the storage base 402 and the fixed base 405 are provided with receiving grooves that can accommodate the propeller 6. The receiving grooves can then provide corresponding protection for the propeller 6. The rear end of the support column 2 has a connecting groove that is inserted into the bottom end of the positioning pin 404. When the positioning pin 404 is inserted into the connecting groove, the rotating plate 401 is in a rightward rotation state, which facilitates the storage and protection of the propeller 6.

[0033] Reference Figure 4 The fasteners include bolts 406, the outer wall of which is threaded to the inner wall of the propeller 6. A protrusion is provided at the right end of the propeller 6 to accommodate the movement of bolts 406. The bottom end of bolts 406 is threaded to the inner wall of the support plate 408. A cross block is provided at the right end of the support plate 408 to be threaded to the bottom end of bolts 406.

[0034] Reference Figures 2-3 and Figure 5The synchronization mechanism 5 includes a rotating ring 501. The inner sidewall of the rotating ring 501 is rotatably and slidably connected to the outer arc surface of the support column 2. When the propeller 6 rotates, the rotating ring 501 can rotate, so as not to affect the normal operation of the propeller 6. The outer wall of the rotating ring 501 is rotatably connected to a connecting plate 502. The number of connecting plates 502 is the same as that of the propeller 6. The side of the connecting plate 502 away from the rotating ring 501 is rotatably connected to the outer wall of the propeller 6. The rotation setting of the connecting plate 502 avoids motion interference when the rotating ring 501 moves laterally.

[0035] Working principle: When the toy airplane stops flying and the propeller 6 needs to be stored and protected, the operator first releases the limiting bolt 406, then moves the rotating ring 501 to the left. When the rotating ring 501 moves, it will drive multiple sets of connecting plates 502 to rotate, thereby bringing the centers of multiple sets of propeller 6 support columns 2 closer together until the propeller 6 changes from a vertical state to a horizontal state. Then, the positioning pin 404 is moved upward to release the insertion of the positioning pin 404 into the connecting groove, and the rotating plate 401 is manually rotated to the left (the initial position of the rotating plate 401 is rotating to the right, and at this time the positioning pin 404 is inserted into the connecting groove). The rotating plate 401 can smoothly rotate around the support column 2 due to the rotating connection structure between its inner side wall and the outer arc surface of the support column 2. At this time, the connecting spring 403 is in a stretched state, and the positioning pin 404 slides on the inner wall of the storage seat 402 as the rotating plate 401 rotates until the bottom end of the positioning pin 404 is in a vertical state. Figure 5 As shown, under the elastic recoil force of the connecting spring 403, the positioning pin 404 quickly engages with the support column 2, thereby limiting and fixing the rotating plate 401, ensuring it is stably in the storage and protection position. Simultaneously, the propeller 6 is located within the receiving grooves of the storage base 402 and the fixing base 405, providing a physical protective barrier to isolate it from possible external collisions, compression, and other damaging factors, effectively protecting the propeller 6 from damage during idleness, transportation, or storage.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
