Description

Technical Field

[0001] This utility model relates to the field of model aircraft technology, specifically to a power-mounted bracket and a model aircraft. Background Technology

[0002] With social development and people's pursuit of a better life, consumers have increasingly higher demands for low-altitude and ultra-low-altitude exploration and experimentation. Traditionally, popular science and experimentation on flight have relied heavily on viewing, visiting, and simulation. Model aircraft are an important method for popularizing flight science and experimentation. However, existing pre-built model aircraft, with their fixed drive mechanisms (such as motors and propellers), determined power output, and locked power sources and remote control receivers, fail to provide users with substantial experiences based on the size and shape of different aircraft, thus insufficiently meeting individual user needs. Furthermore, damage to a single component in a pre-built model aircraft renders the entire product unusable, resulting in high operating costs. Moreover, for beginners, insufficient experience and skill often lead to crashes, further increasing the user experience cost.

[0003] In the existing technology, there are also assembled model aircraft products, which usually include the model aircraft body and various mounting components. Multiple mounting components install the power unit, control unit and power supply unit on the model aircraft body to complete the pre-flight preparation work. Not only is the assembly process time-consuming and labor-intensive, but the insufficient installation accuracy of the mounting components often leads to flight failure or deviation, which is not conducive to improving the user experience. Utility Model Content

[0004] This utility model discloses a power-mounted bracket and a model aircraft, which solves the technical problems of high operating costs, complex operation, and insufficient personalization in existing model aircraft products. It features a reasonable structure, flexible use, low operating costs, and a good user experience. The technical solution adopted is as follows:

[0005] A power-mounted bracket includes a bracket body with a first mounting position, a second mounting position and a third mounting position formed on the bracket body. The first mounting position has multiple positions arranged symmetrically for mounting a flight power unit. The second and third mounting positions are used to mount a control unit and a power supply unit. The bracket body can be connected to an upward-mounted model aircraft to provide flight propulsion.

[0006] Based on the above technical solution, the second and third mounting positions are designed such that when the control unit and power supply unit are mounted on them, the symmetrical planes of the plurality of first mounting positions pass through the center of gravity of the bracket body.

[0007] Based on the above technical solution, the bracket body is integrally formed.

[0008] Based on the above technical solution, the bracket body includes a crossbeam, with multiple first mounting positions symmetrically arranged on both sides of the crossbeam, and the second and third mounting positions arranged near the middle section of the crossbeam.

[0009] Based on the above technical solution, the two ends of the crossbeam are bent downward to form a bent section, and the first mounting position is located on the bent section so that the propeller on the power unit avoids the model aircraft.

[0010] Based on the above technical solution, the top surface of the crossbeam extends horizontally outward to form a wing plate, thereby increasing the contact area between the bracket body and the model aircraft. Preferably, the wing plate has at least one through hole to reduce weight.

[0011] Based on the above technical solution, the crossbeam forms a wiring groove with a lateral opening for accommodating the wires used to connect the power unit, control unit, or power supply unit. Preferably, the opening of the wiring groove is provided with a plurality of toothed plates, each toothed plate consisting of two toothed plates arranged opposite each other to prevent the wires from coming out of the wiring groove.

[0012] Based on the above technical solution, it also includes landing gear, and the lower part of the bracket body is further formed with a fourth mounting position for mounting the landing gear.

[0013] Based on the above technical solution, the landing gear includes a support frame and pulleys. The support frame is n-shaped, and the pulleys are rotatably connected to the two free ends of the support frame. The fourth mounting position is provided with a downward-facing, n-shaped mounting groove. The mounting groove is designed such that when the upper end of the support frame is accommodated in the mounting groove, the two support arms of the support frame laterally press against the groove wall to fix the support frame in the fourth mounting position. Preferably, the support frame is formed by bending metal wire, which is low in cost and has good structural strength.

[0014] Based on the above technical solution, a slot is formed on the top surface of the crossbeam, and the slot extends downward to form a long groove, with the second mounting position and the third mounting position respectively located on both sides of the long groove.

[0015] Based on the above technical solution, it also includes an easy-to-remove block, which is embedded in the upper port of the slot and flush with the top surface of the crossbeam. The easy-to-remove block is detachably connected to the slot wall and also includes two ribs. One end of the ribs is connected to the crossbeam, and the other end of the ribs is connected to the lower part of the bracket body.

[0016] Based on the above technical solution, the second mounting position is used to mount the power supply unit, and a plurality of insertion holes are provided on one side plate of the second mounting position. A pin can pass through the insertion holes and extend into the second mounting position to separate the second mounting position so as to adapt to power supply units of different sizes; the third mounting position includes a back plate, and the back plate is provided with a plurality of L-shaped grippers to limit the control unit.

[0017] A model aircraft includes a base plate and a power-mounted bracket as described above, the bracket being connected upward to the base plate, the base plate being used to support the model aircraft body.

[0018] Based on the above technical solution, the base plate is provided with positioning points to ensure that the bracket and the base plate have good positional accuracy.

[0019] Beneficial effects

[0020] The tray structure of this utility model is reasonable, and the tray body includes several mounting positions. On the one hand, it is flexible in use and can easily mount the power unit, control unit and power supply unit. Users can freely select and match according to their needs to better meet their personalized needs. On the other hand, the mounting positions are open, allowing users to add or connect with other equipment according to their own needs to further meet their personalized needs. Furthermore, when any functional unit fails or is damaged, it can be replaced to extend the service life of the whole machine, resulting in low operating costs.

[0021] This utility model has an ingenious design. When multiple functional units are mounted, the symmetrical planes of the multiple first mounting positions pass through the center of gravity of the bracket body, which helps to improve stability during flight. In addition, when the bracket body is connected upward to the model aircraft, it can also better ensure that the center of the bracket and the center of the model aircraft are coplanar, further ensuring stability during flight.

[0022] In this invention, the bracket body is integrally formed, resulting in high production efficiency and avoiding the use of redundant connectors, which helps to simplify the structure. In addition, it also includes a fourth mounting position for mounting the landing gear. The landing gear is plugged into the bracket body, which is convenient for disassembly and assembly and has a simple structure, which helps to reduce production and manufacturing costs.

[0023] In this invention, to avoid interference between the propeller in the power unit and the model aircraft, several first mounting positions are arranged on the bent section, which makes it easier to install and adapt to different models aircraft and makes the use more flexible. In addition, by adding wing plates, the contact area between the bracket and the model aircraft can be increased, and the connection reliability can be improved.

[0024] In this utility model, the crossbeam of the bracket body is also provided with a slot to further improve adaptability and facilitate the accommodation of structures such as the reinforcing plate extending from the bottom of the model aircraft.

[0025] This utility model includes a base plate, which can support various model bodies, making it flexible to use. In addition, the base plate is provided with several positioning points, which can be identifiers or marking holes, so that the connected bracket and base plate have good positional accuracy, ensuring the stability of the flight process, facilitating user operation, and improving the user experience.

[0041] Example 1

[0042] like Figure 1 As shown, a power-mounted bracket includes a bracket body 1, which includes a crossbeam 11 that extends horizontally and has a flat top surface. The bracket body 1 has a first mounting position 10, a second mounting position 20, and a third mounting position 30. In this embodiment, there are two first mounting positions 10 arranged symmetrically for mounting a flight power unit, the second mounting position 20 for mounting a power supply unit, and the third mounting position 30 for mounting a control unit. The bracket body 1 can be connected to an upward-mounted model aircraft to provide flight propulsion.

[0043] like Figure 1 As shown, two first mounting positions 10 are symmetrically arranged at both ends of the crossbeam 11 and are positioned lower. In this embodiment, the bracket body 1 is integrally formed and made of a material with good toughness and sufficient structural strength. The first mounting position 10 includes a ring 101, which is fixedly connected to the crossbeam 11 upwards. The axis of the ring 101 is arranged perpendicular to the axis of the crossbeam 11. A C-shaped member 102 is fixedly connected to one end of the ring 101. Thus, the ring 101 and the C-shaped member 102 together enclose a first cavity for accommodating the power unit. In addition, several protruding ridges 103 are provided on the inner wall surface of the ring 101. The power unit includes a motor and a propeller connected to the output shaft of the motor. The motor can be tightly fitted in the first cavity. Furthermore, the structure of the C-shaped member 102 makes it convenient for the user to push the motor out of the first cavity for easy replacement.

[0044] The second mounting position 20 is used to mount the power supply unit, and the power supply unit can be tightly mounted on the second mounting position. The power supply unit is existing technology, and those skilled in the art can select it according to their needs.

[0045] In this embodiment, the third mounting position 30 includes a back plate 301. The back plate 301 has a frame structure, which is beneficial for weight reduction. Several L-shaped grippers 302 are provided on the three sides of the back plate 301. When the control unit extends into the third cavity formed by the grippers, the control unit can be limited, thus fixing the control unit on the bracket body 1. The control unit is existing technology, and those skilled in the art can select it according to their needs.

[0046] In this embodiment, both the second mounting position 20 and the third mounting position 30 extend horizontally, allowing the power supply unit and control unit to be arranged horizontally on them. This saves space and facilitates the mounting of other equipment on the model aircraft.

[0047] like Figure 1 As shown, the crossbeam 11 has a side-opening wiring groove 111 for accommodating wires used to connect the power unit, control unit, or power supply unit. The opening of the wiring groove 111 is provided with several toothed plate assemblies 112, each comprising two opposing toothed plates arranged vertically to prevent wires from detaching from the wiring groove.

[0048] In addition, the second mounting position 20 and the third mounting position 30 are designed such that when the control unit and the power supply unit are mounted on them, the symmetrical planes of the two first mounting positions 20 pass through the center of gravity of the bracket body 1. This makes the center of gravity of the bracket body 1 easy to identify. When the bracket 1 is connected to the model aircraft upwards, the bracket and the model aircraft can be better positioned so that their center of gravity positions are matched, thereby improving the stability during flight.

[0049] It also includes landing gear 2, such as Figure 2 As shown, the landing gear 2 includes a support frame 21 and pulleys 22. The support frame 21 is n-shaped, and the two free ends of the support frame 22 extend downwards and outwards. The pulleys 22 are rotatably connected to the two free ends of the support frame 21. In this way, during the takeoff and landing of the model aircraft, the landing gear 2 does not come into contact with the ground, avoiding damage to the support frame, which helps to reduce operating costs and increase the service life of the support frame. The support frame 21 is made of bent metal wire, which is low in cost and has good structural strength.

[0050] Correspondingly, the lower part of the bracket body 1 is formed with a fourth mounting position 40 for mounting the landing gear 2, such as... Figure 1 As shown, the component forming the fourth mounting position 40 is n-shaped and has a mounting groove that extends downwards in an n-shape. The mounting groove is designed such that when the upper end of the support frame 21 is accommodated in the mounting groove, the two support arms of the support frame 21 laterally press against the groove wall of the mounting groove to fix the support frame 21 in the fourth mounting position 40. In this embodiment, the support frame that abuts against the groove wall of the mounting groove has an outward expansion tendency, so that the support frame 21 and the groove wall of the mounting groove have a set clamping force. In other embodiments of this utility model, the component forming the fourth mounting position 40 can also be detachably connected to the bracket body upwards, which can guide the user to assemble it manually, improving interactivity and fun.

[0051] A type of model airplane, such as Figure 2 As shown, the device includes a base plate 7 and a power-mounting bracket. An upper upright plate 100 is fixed to the base plate 7. The crossbeam 11 of the bracket is attached upwards to the base plate 7. In this embodiment, the crossbeam 11 is connected to the base plate 7 upwards by adhesive bonding, such as with tape. In other embodiments of this application, other connection methods such as screwing or snap-fitting can also be used. Furthermore, the base plate 7 has elongated holes to avoid obstructing the propeller of the power unit.

[0052] like Figure 9As shown, the base plate 7 supports the model aircraft body. Positioning points 71 are provided on the base plate 7 to facilitate the positioning of the bracket and ensure good positional accuracy between the bracket and the base plate 7. In this embodiment, the positioning point 71 is an identifier printed on the base plate 7. In other embodiments of this application, the positioning point 71 may be a marking hole, guiding the user to fix the bracket to a predetermined position on the base plate 7, ensuring good positional accuracy between the connected bracket and the base plate 7, guaranteeing stability during flight, facilitating user operation, and improving the user experience.

[0053] In other embodiments of this application, such as Figure 3 As shown, a tail fin 300 can also be installed on the base plate 7 to improve the stability of the model aircraft during flight.

[0054] Example 2

[0055] The difference between this embodiment and Embodiment 1 is that, as Figure 4 As shown, two insertion holes 201 are provided on one side plate forming the second mounting position 20. A pin can pass through the insertion holes 201 and extend into the second mounting position 20 to separate the second mounting position 20, so as to adapt to power supply units of different sizes; it has good adaptability and is more flexible in use.

[0056] Example 3

[0057] The difference between this embodiment and Embodiment 1 or 2 is that, as Figure 5 and 6 As shown, the two ends of the crossbeam 11 are bent downwards to form bent sections 13. The first mounting position 10 is located at the end of the bent section 13 to allow the propeller on the power unit to avoid the model aircraft. In addition, the top surface of the crossbeam 11 extends horizontally outwards to form a wing plate 12 to increase the contact area between the bracket body 1 and the model aircraft. The wing plate 12 has two through holes to reduce weight.

[0058] Example 4

[0059] The difference between this embodiment and embodiment 3 is that, as Figure 8 As shown, the base plate 7 is provided with an upper upright plate 100, and other components, such as creative drawing boards, can also be mounted on the upper upright plate 100. The model aircraft base plate is also provided with a lower upright plate 200.

[0060] A slot is formed on the top surface of the crossbeam 11, which extends downward to form a long groove 5. The second mounting position 20 and the third mounting position 30 are respectively located on both sides of the long groove 5. Specifically, the components forming the second mounting position 20 and the third mounting position 30 enclose the long groove 5, resulting in a compact structure. When the bracket is fixed on the base plate 7, the lower upright plate 200 is accommodated in the slot.

[0061] like Figure 7As shown, it also includes an easy-removable block 6, which is embedded in the upper port of the slot and flush with the top surface of the crossbeam. The easy-removable block 6 is detachably connected to the slot wall. Specifically, the easy-removable block 6 is connected to the slot wall by several connecting columns spaced apart. The connection strength is low. When the lower upright plate 200 needs to be arranged, the user can remove the easy-removable block 6.

[0062] In other embodiments of this application, two ribs are also included, which are symmetrically arranged. One end of the ribs is connected to the bottom surface of the crossbeam 11, and the other end of the ribs is connected to the components forming the fourth mounting position 40, thereby improving the structural strength of the bracket.

[0063] The present invention has been described above by way of example, but the present invention is not limited to the specific embodiments described above. Any modifications or variations made based on the present invention shall fall within the scope of protection claimed by the present invention.
