Description

Technical Field

[0001] This utility model belongs to the field of unmanned aerial vehicle (UAV) technology, specifically relating to a UAV battery mounting rack. Background Technology

[0002] Rotary-wing drones are characterized by their small size, light weight, low cost, flexible operation, and high safety. They are equipped with multiple propellers, which are controlled by multiple motors to achieve flight. Rotary-wing drones are widely used in various fields such as aerial photography, inspection, search and rescue, resource exploration, and agriculture.

[0003] Existing batteries for rotary-wing drones are generally quite heavy. To ensure stable installation, these batteries are often detachably mounted directly onto the drone's fuselage. To ensure stable installation, existing rotary-wing drones typically have battery compartments and corresponding fastening mechanisms. During battery installation, the battery can be directly pushed into the compartment, making installation convenient. However, removing the battery requires simultaneously unfastening the fastening mechanism and grasping and pulling the battery with fingers. Due to the weight of rotary-wing drone batteries and the small size of the gripping area, this disassembly operation is extremely difficult. Utility Model Content

[0004] This utility model provides a drone battery mounting rack, which uses two arc-shaped fixing plates to be mounted between the drone's arms, making the fixation more secure. The battery is placed in the mounting cavity, making it easy to put in and take out the battery. Furthermore, the arc-shaped fixing plates are easier to disassemble and install, thus solving the shortcomings described in the prior art.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A drone battery mounting bracket includes a mounting bracket body with a loading cavity. Symmetrically arranged on both sides of the loading cavity are arc-shaped fixing plates for assembling the mounting bracket body to an installation station. The mounting bracket body serves as a carrier for the battery and is installed between the drone's arms. Specifically, the arc of the fixing plates conforms to the arm's curvature. The mounting bracket body is fixed to the drone by attaching the arc-shaped fixing plates to the corresponding outer circumferential surfaces of the arms. The arc-shaped fixing plates can be fixed with either the lower or upper arc surface; the upper arc surface is preferred. The upper arc structure also serves as a hanging mechanism, reducing the stress on the fixing components between the arc-shaped fixing plates and the arms, resulting in a more stable assembly.

[0007] In a preferred embodiment of this utility model, the arc-shaped fixing plate is provided with fixing holes and a plurality of first weight-reducing holes. The fixing holes are used to fix the loader to the outer circumferential surface of the arm, and pins or screws can be used; the purpose of the first weight-reducing holes is to reduce the weight of the loading frame body.

[0008] As a preferred embodiment of this utility model, the arc-shaped fixing plate is inclined along the extension direction of the installation station. Because the loading frame body is installed between adjacent arms of the drone, and the arms are arranged radially outward from the center, the arc-shaped fixing plate must be consistent with the extension direction of the arms. This makes the width of the loading frame body smaller closer to the center of the drone and larger further away from the center of the drone, forming an overall trapezoidal shape.

[0009] As a preferred embodiment of this utility model, the cavity wall of the loading cavity is provided with perforated holes. The perforated holes facilitate heat dissipation of the battery and reduce weight.

[0010] In a preferred embodiment of this invention, the arc-shaped fixing plate is connected to the loading cavity via an extension plate. Because the dimensions at the point of contact with the machine arm are limited, the arc-shaped fixing plate only needs to be installed near the machine arm; the portion further away from the machine arm can use the extension plate. This reduces manufacturing difficulty and material consumption. The extension plate serves as the connector between the arc-shaped fixing plate and the loading cavity.

[0011] As a preferred embodiment of this utility model, the extended plate is provided with a second weight-reducing hole, the purpose of which is to reduce weight.

[0012] In a preferred embodiment of this invention, the arc-shaped fixing plate and the extended plate are integrally formed. Two integrally formed arc-shaped fixing plates and extended plate structures can be used to connect to the loading cavity.

[0013] In a preferred embodiment of this utility model, two arc-shaped fixing plates and two extended flat plates are integrally formed on a fixed mounting plate, and a loading cavity clearance hole is pre-reserved in the middle of the fixed mounting plate. The fixed mounting plate directly incorporates the loading cavity clearance hole during its forming process, as well as symmetrical extended flat plates and arc-shaped fixing plates on both sides of the loading cavity clearance hole. The end of the extended flat plate away from the loading cavity clearance hole is connected to the arc-shaped fixing plate, and the arc-shaped fixing plate is assembled onto the outer circumferential surface of the machine arm.

[0014] In a preferred embodiment of this utility model, the loading cavity is a composite cavity. The cross-sectional shape of the loading cavity can be circular, square, triangular, etc., designed according to actual needs, but regardless of the shape, it is assembled using a modular forming method.

[0015] In a preferred embodiment of this invention, the mounting plate is provided with a protective strip at the connection point with the loading cavity. The protective strip serves to shield and protect the top of the loading cavity, facilitating assembly and preventing the loading cavity from tilting.

[0016] This utility model features symmetrical arc-shaped fixing plates that are hung and fixed to adjacent machine arms in a two-point symmetrical manner, ensuring high stability. It also facilitates the assembly of the loading frame body, making battery loading and unloading convenient. Furthermore, the loading frame body is easy to install and disassemble, and the entire loading frame body is equipped with weight-reduction holes to reduce overall weight.

Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0018] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0019] 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.

[0020] Example:

[0021] A type of drone battery mounting rack, such as Figure 1 As shown, the device includes a loading frame body 1, which has a loading cavity 11. The loading frame body serves as a carrier for the battery and is installed between the arms of the drone. To ensure a close fit with the arms, symmetrical arc-shaped fixing plates 12 are arranged on both sides of the loading cavity 11. The curvature of the arc-shaped fixing plates conforms to the arm. The loading frame body is fixed to the drone by attaching the arc-shaped fixing plates to the corresponding outer circumferential surfaces of the arms. Furthermore, the arc-shaped fixing plates can be fixed with either the lower or upper arc surface. This embodiment uses the upper arc surface fixing. The upper arc structure also serves as a hanging mechanism, reducing the stress on the fixing components between the arc-shaped fixing plates and the arms, making the assembly more stable.

[0022] Each arc-shaped fixing plate 12 is provided with a fixing mounting hole 13 and several first weight reduction holes 14. The fixing mounting hole is used to fix it to the outer circumferential surface of the arm, and can be made of pins or screws, preferably screws. Accordingly, the fixing mounting hole is a threaded hole. The purpose of the first weight reduction holes is to reduce the weight of the loading frame body.

[0023] Since the loading rack body is installed between adjacent arms of the drone, and the arms are arranged radially outward from the center, the arc-shaped fixing plate 12 is inclined along the extension direction of the installation station. That is to say, the arc-shaped fixing plate must be consistent with the extension direction of the arms. This makes the width of the loading rack body smaller as it gets closer to the center of the drone, and wider as it gets further away from the center of the drone, forming an overall trapezoidal shape.

[0024] Because the dimensions at the point where it contacts the machine arm are limited, the arc-shaped fixing plate 12 only needs to be installed near the machine arm, while the portion further away from the machine arm can use an extension plate. This reduces manufacturing difficulty and material consumption. The extension plate serves as a connector between the arc-shaped fixing plate and the loading cavity. Therefore, the arc-shaped fixing plate 12 is connected to the loading cavity 11 via the extension plate 15. To reduce weight, the extension plate 15 is provided with a second weight-reducing hole 16. Furthermore, the extension plate 15 and the arc-shaped fixing plate 12 can be assembled together or directly formed as a single piece. That is, the extension plate 15 and the arc-shaped fixing plate 12 on both sides of the loading cavity 11 can be two integrally formed structures or a single integrally formed structure.

[0025] When two integrally molded structures are used, the extended plates on each side are fixedly connected to the loading cavity 11. This embodiment demonstrates an integrally molded structure as an example. Two arc-shaped fixing plates 12 and two extended plates 15 are integrally molded on the fixed mounting plate 17. To accommodate the loading cavity 11, a loading cavity clearance hole is pre-drilled in the middle of the fixed mounting plate 17. The fixed mounting plate is directly formed with the loading cavity clearance hole, as well as symmetrical extended plates and arc-shaped fixing plates on both sides of the loading cavity clearance hole. The end of the extended plate away from the loading cavity clearance hole is connected to the arc-shaped fixing plate, and the arc-shaped fixing plate is assembled onto the outer circumferential surface of the arm.

[0026] The top of the loading cavity 11 is open and fixedly connected to the periphery of the loading cavity clearance hole.

[0027] The cavity wall of the loading chamber 11 is provided with perforated holes. The perforated holes facilitate heat dissipation of the battery and reduce weight. Furthermore, the loading cavity 11 used can be an integral structure or a combined cavity, that is, an assembled structure. This embodiment uses an assembled structure as an example for demonstration. Since the cross-sectional shape of the loading cavity can be circular, square, triangular, etc., it is designed according to actual needs. Taking a square shape as an example, it includes a loading base plate 121, a first loading side plate 122, a second loading side plate 123, a third loading side plate 124, and a fourth loading side plate 125. The loading base plate 121 has an upper stop edge on its four sides. The first loading side plate 122, the second loading side plate 123, the third loading side plate 124, and the fourth loading side plate 125 are connected end to end to form a square. The bottom of the four loading side plates is located inside the upper stop edge. The contact edges of adjacent loading side plates are fixedly connected with L-shaped reinforcing plates. The tops of the four loading side plates are fixedly connected to the wall of the loading cavity clearance hole, and a reinforcing fixing rod is installed through the fixed mounting plate 17 and the loading base plate 121. Correspondingly, protective strips are installed around the perimeter of the loading cavity clearance hole. These protective strips correspond one-to-one with the loading side plates, limiting the top of the loading side plates. The protective strips serve to shield and protect the top of the loading cavity, facilitating assembly and preventing the loading cavity from tilting.

[0028] Of course, the entire loading rack can also be molded as a single piece, using 3D printing or injection molding.
