Description

Technical Field

[0001] The utility model relates to the field of design and manufacture of model aircraft, in particular to a remote-controlled toy airplane with an airdrop cargo hold. Background Art

[0002] There are two main types of traditional toy airplanes: one is a toy airplane without human intervention control, and the other is a toy airplane with human control. Currently, most toy airplanes with human control only have basic flight functions, and this single-function toy airplane greatly reduces the control pleasure of the operator.

[0003] Therefore, in order to increase the interest of the existing remote control toy airplane, some functions can be added on the basis of the existing remote control toy airplane. Utility Model Content

[0004] In view of the current situation that the existing remote control toy airplanes have only one function, the utility model provides a remote control toy airplane with an airdrop cargo hold, so that the remote control airplane can be loaded with airdrop objects and the airdrop function can be realized during flight, which greatly increases the fun of the toy airplane and improves the operator's interest in flight control.

[0005] The utility model discloses a remote control toy airplane with an airdrop cargo hold, wherein a columnar airdrop cargo hold accommodating area is reserved under the fuselage of an existing remote control airplane, and the airdrop cargo hold is fixedly installed inside the airdrop cargo hold. The airdrop cargo hold comprises a cargo hold frame, a sliding door, a door reset tension spring, a cargo hold end ring cover and a locking mechanism.

[0006] The cargo hold frame is a cylindrical hollow frame with a drop port on the side. The sliding hatch is fitted to the inner wall of the cargo hold frame; the front and rear ends of the left side are respectively fixedly connected to one end of two hatch reset tension springs. The two hatch reset tension springs are fitted to the inner wall of the cargo hold frame, and the other ends are respectively fixedly connected to the bosses designed on the inner walls of the front and rear ends of the cargo hold frame. The positions of the tension springs and the hatch in the axial direction of the cargo hold frame are limited by the cargo hold end ring cover fixedly installed at the front and rear ends of the cargo hold frame. The cargo hold end ring cover is designed with a groove in the circumferential direction, and the two opposite side walls of the groove are the front and rear annular surfaces of the cargo hold end ring cover; and the width of the front annular surface is designed to be smaller than the width of the rear annular surface; and after the cargo hold end cover is installed and fixed, there is a gap between the outer edge of the front annular surface of the cargo hold end cover and the inner wall of the cargo hold frame, and the gap size is smaller than the cross-sectional diameter of the tension spring; the tension spring is placed in the groove through the gap for positioning. Then the cargo hold end ring cover limits the position of the tension spring and the hatch in the axial direction of the cargo hold frame.

[0007] The front annular surface of the annular end cover at the cargo hold end is designed with three recesses in the circumferential direction; the middle and left ends of the inner wall surfaces at the front and rear ends of the sliding hatch are designed with protrusions as sliders. When the sliding hatch is in the closed state, the two sliders on the hatch on one side of the cargo hold frame and the boss on the inner wall of the cargo hold frame enter the groove of the annular end cover at the cargo hold end through the three recesses on the annular end cover at the cargo hold end on the same side. At the same time, the three recesses of the annular end cover at the cargo hold end are staggered from the boss A and the slider in the circumferential direction, and the staggered angle should meet the requirement that the three recesses are not on the moving path of the boss on the sliding hatch.

[0008] Therefore, the hatch can be opened automatically by the hatch reset tension spring; when the hatch moves counterclockwise to the extreme position along the axial direction of the cargo hold frame, the tension spring stretches, and the right side of the sliding hatch contacts and limits the bosses on the front and rear end inner walls of the cargo hold frame; at the same time, the sliding hatch is locked in position by the locking mechanism.

[0009] The priority of this utility model is:

[0010] 1. The utility model remote control toy airplane is designed with an airdrop mechanism, which increases the airdrop operation during the flight and enhances the fun of the airplane flight process;

[0011] 2. The utility model remote control toy airplane is provided with an airdrop mechanism, and the airdrop cabin can be opened with only one micro switch, which has a simple structure, light weight and is easy to implement.

[0023] The utility model discloses a remote-controlled toy airplane with an airdrop cargo hold, which improves the structure of an existing remote-controlled toy airplane. An airdrop cargo hold and an airdrop signal receiving module for receiving airdrop signals are added to the existing remote-controlled toy airplane, thereby realizing the airdrop function of the remote-controlled toy airplane.

[0024] The conventional layout of the existing remote control toy airplane includes a fuselage, wings (including ailerons and flaps), a vertical tail (including a rudder), a horizontal tail (including an elevator), a propulsion device, a signal receiving device, a steering gear, a landing device, etc. In the utility model, a cylindrical area with an axis along the front-rear direction of the fuselage is reserved in the fuselage of the existing remote control toy airplane as an airdrop cabin installation position for accommodating an airdrop cargo hold.

[0025] like Figure 1 , Figure 2 As shown, the airdrop cargo hold is a storage structure for airdropped items, and the overall structure is a cylindrical structure, which mainly includes a cargo hold frame 101, an arc-shaped sliding door 102, a door reset spring 103, a cargo hold end ring cover 104 and a locking mechanism 105.

[0026] The cargo hold frame 101 is a mounting base for other airdropped components. It is a cylindrical hollow frame, which is formed by a front circular ring frame 101a, a terminal circular ring frame 101b, and a circumferential connecting beam 101c. The front circular ring frame 101a is coaxially arranged with the terminal circular ring frame 101b, and three connecting beams 101c are arranged at equal angles in the circumferential direction. The front and rear ends of the three connecting beams 101c are respectively connected to the front circular ring frame 101a and the terminal circular ring frame 101b to form an integral cargo hold frame. The space between any two of the three connecting beams 101c is used as an airdrop port.

[0027] The cargo hold frame 101 is provided with cargo hold end ring covers 104 at both ends. The cargo hold end ring covers 104 serve as limiting components for the arc-shaped sliding door 102 and the door return spring 103. Figure 3 , Figure 4 As shown, the specific structure is as follows:

[0028] The cargo hold end annular end cover 104 is an annular structure as a whole, and is designed with a groove 104a in the circumferential direction. The two opposite side walls of the groove 104a are the front and rear annular surfaces of the cargo hold end annular end cover 104; and the width of the front annular surface is designed to be smaller than the width of the rear annular surface. At the same time, three lugs A104b are designed at equal angles in the circumferential direction on the rear annular surface of the cargo hold end annular end cover 104, which are respectively used to cooperate with three lugs B101d designed at equal angles in the circumferential direction on the outer wall of the end of the cargo hold frame 101, and are fixed by bolts to achieve the fixation between the cargo hold frame 101 and the cargo hold end annular end cover 104.

[0029] Before installing the annular end cover 104 at the cargo hold end, the arc-shaped sliding door 102 and the door return spring 103 need to be installed first, as follows:

[0030] like Figure 5 As shown, the arc-shaped sliding door 102 is an arc-shaped plate-like structure, which is placed inside the front circular frame 101a and the rear circular frame 101b, and the outer walls are respectively fitted with the inner walls of the front circular frame 101a and the rear circular frame 101b; at the same time, the front and rear ends of the arc-shaped sliding door 102 are respectively flush with the front and rear ends of the cargo hold frame 101.

[0031] Described hatch reset tension spring 103 is two, one end is respectively fixedly installed on the boss A101e of the inner side wall design of the connecting beam 101c at both ends on the right side of the airdrop port by screws, and is bent in an arc shape, respectively counterclockwise along the front end circular ring frame 101a and the rear end circular ring frame 101b inner wall surface setting, circumferentially fits with the front end circular ring frame 101a and the rear end circular ring frame 101b inner wall. The other ends of two hatch reset tension springs 103 are respectively fixed on the boss B102a designed at the position of the left side ends of the sliding door 102 by screws. After the above-mentioned hatch reset tension spring 103 is connected with the sliding door 102, the hatch reset tension spring 103 applies counterclockwise pulling force to the sliding door 102, so that the sliding door 102 is located on the left side of the airdrop port as a whole, and the airdrop port will not be blocked. At this time, the sliding door 102 is in an open state. When the hand pulls the sliding door 102 to move clockwise, the door return spring 103 stretches to store energy until the right side of the sliding door 102 contacts the boss A, and the sliding door 102 is limited by the boss A101e, and the sliding door 102 covers the airdrop port, closing the airdrop port, and the sliding door 102 is in a closed state. At this time, the sliding door 102 is released, and the sliding door 102 is affected by the rebound force of the door return spring 103, and moves counterclockwise to return to the open state.

[0032] In order to ensure the positioning of the door return spring 103 and the sliding door 102 in the front-to-back direction during the opening and closing process of the above-mentioned sliding door 102, an annular end cover 104 is installed at both ends of the cargo hold frame 101, and protrusions are designed at the middle of the inner wall surface at the front and rear ends and the left end of the sliding door 102 as a slider 102b; the sliders 102b at the front and rear ends of the sliding door 102 are combined with the bosses A101e at both ends of the connecting beam 101c on the right side of the airdrop port to achieve directional sliding of the sliding door 102 after the annular end cover 104 at the cargo hold is installed. The specific installation method is as follows:

[0033] Three recesses 104c are designed on the outer edge of the front annular surface of the cargo hold end annular end cover 104 in the circumferential direction; when the sliding hatch 102 is in the closed state, the three recesses 104c respectively cooperate with the boss A101e and the two sliders on the same side of the connecting beam 101 and the sliding hatch 102, so that the boss A101e and the two sliders enter the circumferential groove of the cargo hold end annular end cover 104 through the recesses 104c; because the outer diameter of the front annular surface of the cargo hold end annular end cover 104 is smaller than the rear annular surface, when the cargo hold end annular end cover 104 is installed, there is a certain gap between the outer edge of its front annular surface and the inner wall surface of the cargo hold frame 101, and the width of the gap is slightly smaller than the diameter of the hatch door reset tension spring 103. Therefore, when the cargo hold end annular end cover 104 is installed, the hatch door reset spring 103 can be squeezed through the gap to insert the hatch door reset spring 103 into the circumferential recess 104c of the cargo hold end annular end cover 104. At this time, tighten the annular end cover 104 at the cargo hold end, so that the inner wall of the outer annular surface of the annular end cover 104 at the cargo hold end fits with the end surface of the cargo hold frame 101; further, by rotating the annular end cover 104 at the cargo hold end, the boss A101e and the slider 102b are staggered with the three recesses 104c, and the staggered angle should be such that the three recesses are not on the moving path of the boss on the sliding door 102. At the same time, the three lugs A104b on the annular end cover 104 at the cargo hold end are matched with the three lugs B101d on the circumference of the annular end cover 104 at the cargo hold end, and fixed by screws. In the above manner, after installing the annular end cover 104 at the cargo hold end, the door return spring 103, the boss A101e and the two sliders 102b are all positioned in the groove 104a.

[0034] The airdrop cargo hold of the above structure is placed in the airdrop cabin installation position and fixed. The fixing method can be through the outer end surface of the cargo hold end ring cover 104 at the front and rear ends and the front and rear side walls of the airdrop cabin installation position through gluing, or on the outer wall of at least two connecting beams 101c, a boss is designed along the axial direction of the cargo hold frame 101, and it is respectively plugged and fixed with the recess designed on the circumference of the airdrop cabin body. When the sliding door 102 is in the open state, airdrops can be placed in the airdrop cargo hold, and then the sliding door is manually closed, and the locking mechanism 105 is used to realize the locking of the sliding door 102 after closing.

[0035] The locking mechanism 105 includes a micro unlocking motor 105a (a suction-type micro frame electromagnet) and a lock hook 105b. Figure 2 As shown. Among them, the micro unlocking motor 105a is fixedly installed on the inner wall surface of the middle part of the connecting beam 101c on the right side of the airdrop port, and the output direction of the lock tongue is set along the long direction of the connecting beam 101c. The lock hook 105b is an L-shaped structure, one side of which is fixedly installed on the sliding door 102 and is located in the middle of the right side of the sliding door 102, and is perpendicular to the right side of the sliding door 102. The other side of the hook lock is used as the lock tongue matching side, and its inner side surface is used to match with the lock tongue to achieve locking. At the same time, the outer side surface of the lock tongue matching side is designed as an inclined surface, which is used to match with the lock tongue to achieve lock tongue retraction. Therefore, during the closing process of the sliding door 102, the outer inclined surface of the lock tongue matching side contacts the lock tongue, and the sliding door 102 is further closed to retract the lock tongue until the inclined surface is separated from the lock tongue, and the lock tongue pops out at this time. At this time, the lock tongue cooperates with the inner side of the lock tongue matching side to achieve locking after the sliding door 102 is closed. When it is necessary to open the sliding door 102, an airdrop signal is sent to the airdrop signal receiving module, which sends the airdrop signal to the micro unlocking motor 105a to control the retraction of the lock tongue. At this time, the lock tongue disengages from the lock tongue mating side, and the sliding door 102 is automatically opened by the door reset spring 103.

[0036] The opening control of the sliding door 102 can be achieved by adding a control channel in the flight controller of the existing toy airplane to control the micro unlocking motor 107 .

[0037] The airdrop control process of the utility model is as follows:

[0038] On the ground, first turn on the power of the aircraft and the remote control, and the remote control is matched with the airdrop signal receiving module. After the matching is completed, the remote control can be used for control. Press the airdrop button of the remote control, the flight controller receives the signal, and sends a command to the micro unlocking motor 105a, and then the lock tongue of the micro unlocking motor 105a retracts, and the lock hook 105b loses the lock tongue constraint at this time, and slides counterclockwise to open under the pull of the door reset tension spring 103. At this time, the user can place the airdrop in the cargo hold. Then pull the door handle to close the arc sliding door 102. When the sliding door 102 is closed in place, the lock hook 105b also reaches the specified position, and the lock hook is just caught by the lock tongue. At this time, the sliding door 102 is locked, and the airdrop loading is completed.

[0039] When the plane is flying in the air and the user decides to airdrop cargo, the user presses the airdrop button on the remote control, the receiver receives the signal, and sends a command to the micro unlocking motor 105a, and then the lock tongue of the micro unlocking motor 105a retracts, the lock hook 105b loses the lock tongue constraint, and the sliding door 102 opens under the action of the door reset spring 103, and the airdrop is released under the action of gravity.
