Description

Technical Field

[0001] This application relates to the field of drone battery equipment technology, and in particular to a heat-dissipating aluminum alloy frame for a drone battery compartment. Background Technology

[0002] With the rapid development of technology, drones are gradually entering the public eye in addition to their military applications, such as drone toys, drone photography, and drones spraying pesticides in agriculture. It can be seen that the use of drones is becoming more and more popular, and the low-altitude economy to which drones belong is also an important development route.

[0003] The low-altitude economy is a new and comprehensive economic form. It takes low-altitude flight activities as its core and uses new productive forces composed of manned or unmanned flight, low-altitude intelligent network and other technologies to interact with factors such as airspace and market, driving the development of low-altitude infrastructure, low-altitude aircraft manufacturing, low-altitude operation services and low-altitude flight support.

[0004] The invention patent with application publication number CN109562839A discloses a drone battery compartment and a drone. The invention patent discloses a drone battery compartment and a drone fuselage arranged in an up-down position. The drone battery compartment is used to install the battery, while the drone battery shell is usually a closed shell, which completely encloses the battery cell, thus making it difficult for the battery to dissipate heat. Summary of the Invention

[0005] In order to improve the efficiency of heat dissipation of drone batteries during use, this application provides a heat dissipation aluminum alloy frame for drone battery compartments.

[0006] This application provides a heat-dissipating aluminum alloy frame for a drone battery compartment, employing the following technical solution: A heat-dissipating aluminum alloy frame for a drone battery compartment includes a lower frame, an upper frame, and a battery box. The lower frame and the upper frame are detachably connected, and the battery box is detachably installed between the lower frame and the upper frame. The battery box has a heat dissipation window, and two or more window panels are rotatably installed on the battery box. A control component for controlling the opening and closing of the window panels is installed on the battery box.

[0007] By adopting the above technical solution, the heat dissipation window on the battery box provides a channel for battery heat dissipation. The control component can control the opening and closing of the window. The window can be opened during the battery installation process of the drone, allowing air to enter the battery box through the heat dissipation window when the drone is in flight, achieving efficient heat dissipation. When the drone is not working and the battery is removed, the window can be closed to protect the battery. This approach balances heat dissipation and protection, effectively improving the battery's performance and lifespan.

[0008] In one specific implementation, the control component includes a slide plate mounted on the battery box. The slide plate has a groove, through which a lever is slidably mounted. A first spring is connected to the lever, with the end of the first spring away from the lever connected to the slide plate. A lever plate is mounted on the end of the lever near the window panel, and the lever plate has a movable groove. A swing arm is mounted on the window panel, and a protruding rod is mounted on the swing arm, extending into the movable groove and slidably connected to the lever plate. A guide rod is mounted on the battery box, and a lifting plate is slidably mounted on the guide rod. A second spring is sleeved on the guide rod. A pressure block for controlling the movement of the lever is mounted on the lifting plate, and the upper frame presses down on the lifting plate to control its movement.

[0009] By adopting the above technical solution, when the upper frame is assembled and fixed with the battery box, the upper frame will press the lifting plate to slide down along the guide rod, and the second spring will be compressed; the lifting plate will drive the pressure block to move down synchronously, and the pressure block will push the lever to move along the slide groove of the slide plate, and the first spring will be stretched; when the lever moves, it will drive the lever plate to move, and the lever plate will drive the swing arm to swing through the cooperation of the movable groove and the protruding rod, thereby driving the window panel to rotate and realize the opening of the heat dissipation window; when the upper frame is disassembled, the second spring will restore its deformation and push the lifting plate to reset, the first spring will restore its deformation and pull the lever to reset, the lever plate will drive the swing arm to swing in the opposite direction, and the window panel will close the heat dissipation window, realizing the automatic opening and closing control of the window panel, which is convenient to operate and does not require additional manual operation, and is suitable for the assembly and use process of drones.

[0010] In one specific implementation, the pressure block has an arc-shaped surface on the side near the lever, the pressure block abuts against the lever, and the surface of the lever abutting against the pressure block is a bevel.

[0011] By adopting the above technical solution, the combination of the arc surface and the inclined surface can reduce the friction between the pressure block and the lever, making the process of the pressure block pushing the lever move more smoothly, avoiding jamming, ensuring the stability and reliability of the control component, and also reducing wear between parts and extending service life.

[0012] In one specific implementation, a limiting plate is mounted on the lever, and the limiting plate is disposed on both sides of the slide plate.

[0013] By adopting the above technical solution, the limiting piece can limit the sliding stroke of the lever, prevent the lever from disengaging from the slide groove of the slide plate during sliding, and ensure the stability of the connection between the lever and the slide plate.

[0014] In one specific implementation, a lower support plate supporting the battery box is installed on the lower frame, and an upper support plate pressing down on the battery box is installed on the upper frame.

[0015] By adopting the above technical solutions, the lower support plate can provide stable support for the battery box, ensuring the installation stability of the battery box during use; the upper support plate can apply downward pressure to the battery box during assembly, making the connection between the battery box and the lower frame tighter, preventing the battery box from loosening due to vibration during drone flight, and also increasing the gap between the lower frame, the upper frame and the battery box, enhancing the heat dissipation of the battery box.

[0016] In one specific implementation, a lower slot is provided on the lower frame, and a lower locking block is installed on the bottom surface of the battery box to engage with the lower slot; an upper slot is provided on the upper frame, and an upper locking block is installed on the top surface of the battery box to engage with the upper slot.

[0017] By adopting the above technical solution, the cooperation between the lower locking block and the lower locking slot can realize the lateral positioning of the battery box and the lower frame, and the cooperation between the upper locking block and the upper locking slot can realize the lateral positioning of the battery box and the upper frame, effectively preventing the battery box from shifting in the horizontal direction, further improving the stability and firmness of the battery box installation, and avoiding the battery box shaking during the drone's flight, which would affect the heat dissipation effect and the safety of use.

[0018] In one specific implementation, a lower fitting piece is provided on the lower frame, and the lower fitting piece forms a positioning step with the lower frame; an upper fitting piece is provided on the upper frame to be assembled with the lower fitting piece.

[0019] By adopting the above technical solution, the splicing and matching of the lower and upper panels can achieve precise positioning and connection between the lower and upper frames. The positioning steps can limit the installation position of the upper panel, ensuring the coaxiality and fit of the upper and lower frames after assembly, making the assembly process more convenient and efficient. At the same time, it can also improve the sealing and stability of the overall structure and reduce the vibration and noise between the frames during the flight of the drone.

[0020] In one specific implementation, a locking assembly for engaging the battery box is installed on the lower frame. The locking assembly includes a fixing plate, which is mounted on the lower frame. A spherical cover is installed on the fixing plate. A connecting rod is installed on the battery box, and a ball that engages with the spherical cover is installed on the connecting rod.

[0021] By adopting the above technical solution, the engagement of the ball and the spherical cover can achieve quick connection and initial fixation between the battery box and the lower frame. The battery box can be limited before assembling the upper frame, which facilitates the subsequent installation of the upper frame. The spherical structure has good elastic deformation space, which facilitates the insertion and release of the ball. This not only ensures the reliability of the connection, but also facilitates the disassembly and maintenance of the battery box, thus improving the overall ease of assembly and disassembly.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. Through the cooperation of heat dissipation windows, window panels and control components, the battery achieves efficient heat dissipation and protection functions, improves battery performance and lifespan, and balances practicality and safety.

[0023] 2. Through the automated design of the control components, the window panel can be automatically opened and closed by assembling and disassembling the upper frame, without the need for additional manual operation. This is suitable for drone usage scenarios and is convenient and efficient to operate.

[0024] 3. The lower frame, upper frame and battery box are connected by multiple positioning and connection structures such as slots, blocks, plates and components, which ensure the installation stability and firmness of the overall structure, effectively cope with the vibration and impact during the flight of the drone and improve the reliability of the product.

[0033] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0034] This application discloses a heat-dissipating aluminum alloy frame for a drone battery compartment, referring to... Figure 1 and Figure 2 It includes a lower frame 1 and an upper frame 2, which are detachably connected to the lower frame 1. Both the upper frame 2 and the lower frame 1 are aluminum alloy frames. A battery box 3 is detachably installed between the upper frame 2 and the lower frame 1. The battery box 3 is also made of aluminum alloy.

[0035] Reference Figure 2 and Figure 3 A lower support plate 11 for placing the battery box 3 is fixedly installed on the lower frame 1. A lower slot 12 is provided on the lower frame 1. A lower fitting piece 13 for connecting with the upper frame 2 is provided on the lower frame 1. The lower fitting piece 13 and the lower frame 1 form a positioning step 14.

[0036] An upper support plate 21 for pressing the battery box 3 is fixedly installed on the upper frame 2. An upper slot 22 is provided on the upper frame 2. An upper fitting piece 23 connected to the lower frame 1 is fixedly installed on the upper frame 2.

[0038] When assembling the lower frame 1, battery box 3 and upper frame 2, first place the battery box 3 on the lower support plate 11 of the lower frame 1 and make the lower locking block 31 snap into the lower locking groove 12. Then press the upper frame 2 on the battery box 3 so that the lower connecting piece 13 covers the upper connecting piece 23 and the upper locking block 32 snaps into the upper locking groove 22. When the upper connecting piece 23 abuts against the positioning step 14, tighten the upper connecting piece 23 and the lower connecting piece 13 with bolts.

[0039] A locking assembly 15 for locking the battery box 3 is installed on the lower frame 1. The locking assembly 15 includes a fixing plate 151, which is fixedly installed on the lower support plate 11. A locking cover 152 is fixedly installed on the fixing plate 151. The locking cover 152 is a spherical cover. A connecting rod 153 is fixedly installed on the side wall of the battery box 3. A locking ball 154 that locks into the locking cover 152 is fixedly installed on the connecting rod 153.

[0040] When the battery box 3 is placed on the lower frame 1, pressing the battery box 3 will press the locking ball 154 into the locking cover 152, so that the locking ball 154 is locked in the locking cover 152, thereby connecting the battery box 3 to the lower frame 1, and the lower frame 1 can also be used to initially limit the battery box 3.

[0041] Reference Figure 4 The battery box 3 has a heat dissipation window 33. Two or more window panels 34 are rotatably mounted on the battery box 3. When the heat dissipation window 33 is closed, the window panels 34 are tilted and adjacent window panels 34 are in close contact. The battery box 3 is equipped with a control component 35 that controls the opening and closing of the window panels 34. (Refer to...) Figure 5 , Figure 6 and Figure 7 The control component 35 includes a slide plate 351, which is fixedly mounted on the battery box 3. A groove 3511 is provided on the slide plate 351, through which a lever 352 is slidably mounted. A first spring 353 is fixedly mounted on the slide plate 351 and is also fixedly connected to the lever 352. A limiting piece 3521 is fixedly mounted on the lever 352, and the limiting piece 3521 is located on the upper and lower sides of the slide plate 351. A lever plate 354 is fixedly connected to the bottom end of the lever 352, and a movable groove 3541 is provided on the lever plate 354. A swing arm 341 is fixedly mounted on the window panel 34, and a protruding rod 342 is fixedly mounted on the swing arm 341. The protruding rod 342 extends into the movable groove 3541 and is slidably connected to the swing arm lever plate 354.

[0042] A guide rod 355 is fixedly installed on the upper locking block 32. A lifting plate 356 is slidably installed on the guide rod 355. Both ends of the lifting plate 356 extend out of the upper locking block 32. A second spring 357 is sleeved on the guide rod 355. One end of the second spring 357 is fixedly connected to the lifting plate 356, and the other end is fixedly connected to the upper locking block 32. A pressure block 358 is fixedly installed on the bottom surface of the lifting plate 356. The side of the pressure block 358 near the lever 352 is opened into an arc-shaped surface. The lever 352 abuts against the pressure block 358. The surface where the lever 352 abuts against the pressure block 358 is opened into a slope.

[0043] When the upper frame 2 presses against the battery box 3, the upper frame 2 will press the lifting plate 356 to slide downward on the guide rod 355. Figure 7The lifting plate 356 shown is in the state after the upper frame 2 presses down the lifting plate 356 to descend. When the lifting plate 356 descends, it will drive the pressure block 358 to descend. Through the action of the arc surface of the pressure block 358, the pressure block 358 will push the lever 352 to move. The lever 352 will drive the lever 354 to move. The lever 354 will push the swing arm 341 to swing. The swing arm 341 will drive the window panel 34 to rotate, thereby making the window panel 34 rotate and creating a gap between two adjacent window panels 34. This facilitates ventilation into the battery box 3 during the flight of the UAV and facilitates heat dissipation inside the battery box 3.

[0044] The implementation principle of this embodiment is as follows: During assembly, the battery box 3 is first initially fixed to the lower frame 1 by the snap-fit ​​component 15. Then, precise positioning is achieved through the cooperation of the lower snap-fit ​​block 31 and the lower snap-fit ​​slot 12, and the upper snap-fit ​​block 32 and the upper snap-fit ​​slot 22. Finally, the overall assembly is completed by the splicing of the upper fitting piece 23 and the lower fitting piece 13 and the tightening of bolts. During assembly, the upper frame 2 presses the lifting plate 356, and the window panel is driven to open by the control component 35 to achieve heat dissipation. During disassembly, the control component 35 automatically resets, the window panel closes, and the battery is protected. This structure takes into account both high heat dissipation efficiency and protection, is stable and reliable in installation, and is convenient to assemble and disassemble, making it suitable for the use of drones.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
