[0032] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] Please refer to Figures 1-4 The retractable battery holder disclosed in this utility model will now be described. This utility model consists of three parts, as follows: Figure 1 , Figure 2As shown, it includes a carbon plate 1, an adjusting bracket 2, and a strap 3. The carbon plate 1 is used to place the battery pack. Several strap holes 11 are opened through the top of the carbon plate 1. The adjusting bracket 2 is installed on the top of the carbon plate 1 and is used to limit the position of the battery pack. The strap 3 is set in the strap holes 11 and is used to fix the battery pack.

[0034] In this embodiment, the specific shapes of the carbon plate 1 and the adjusting bracket 2 are as follows: Figure 1 As shown. Figure 2 This is the state of the battery pack when installed in this application. The adjustment bracket 2 provides support by pushing the battery pack from three directions. Combined with the straps 3, it can securely fix the battery pack. The battery pack is a smart battery, and its status can be intelligently monitored via a mobile app. The carbon plate 1 is made of carbon fiber material, and the adjustment bracket 2 is manufactured using 3D printing, which reduces the overall weight while ensuring strength and improving the drone's endurance. By setting up the adjustment bracket 2 and working in conjunction with the straps 3, it is ensured that the battery pack will not loosen due to vibration or external forces during flight, improving flight safety. Furthermore, the adjustment bracket 2 adopts a telescopic adjustment design, which can adapt to battery packs of different sizes without replacing the bracket, greatly reducing installation and adjustment time.

[0035] Preferably, two strap holes 11 form a group, and the two strap holes 11 are respectively opened at the top of the carbon plate 1 near the edge. At least three sets of strap holes 11 are opened at the top of the carbon plate 1, and the three sets of strap holes 11 are distributed in an array along the edge of the carbon plate 1. Multiple sets of strap holes 11 can provide flexible fixing points for the straps 3, adapting to different battery pack layouts. The design of multiple sets of strap holes 11 can provide flexible binding methods for the straps 3. In addition to the binding method shown in the figure, cross binding can also be achieved through different strap holes 11, adapting to different battery pack layouts and providing a more flexible battery pack arrangement for the UAV.

[0036] like Figure 3 As shown, the adjustment bracket 2 includes a main bracket 21, a sliding groove 24, a horizontal extension bracket 25, a vertical extension bracket 26, and a hand-tightening knob 27. The main bracket 21 is installed on the top of the carbon plate 1. A first slide rail 22 is opened horizontally on the side wall of the main bracket 21, and a second slide rail 23 is opened vertically on the top of the main bracket 21. The sliding groove 24 is arranged in pairs and passes through the top of the carbon plate 1. The horizontal extension brackets 25 are arranged in pairs, with one end slidably connected to the first slide rail 22 and the other end slidably connected to the sliding groove 24. The vertical extension bracket 26 is slidably connected to the top of the main bracket 21 through the second slide rail 23. Several hand-tightening knobs 27 are respectively arranged on the side walls of the first slide rail 22 and the second slide rail 23, and the hand-tightening knobs 27 are threadedly connected to the first slide rail 22 and the second slide rail 23.

[0037] In this embodiment, the shapes and positions of the main support 21, the horizontal expansion support 25, and the vertical expansion support 26 are as follows: Figure 3 As shown, the main support 21 is composed of two cross-shaped connections, with its bottom fixed to the carbon plate 1 via bolts. There are two first slide rails 22, arranged horizontally, through which the main support 21 slidably connects to the horizontal expansion support 25. There are also two second slide rails 23, arranged vertically, through which the main support 21 slidably connects to the vertical expansion support 26. The main support 21 can be arbitrarily adjusted in length and height within a certain range via the horizontal and vertical expansion supports 25 and 26, with a length adjustment range of 169.4-209.4 mm and a height adjustment range of 123-166 mm. The end of the hand-tightening knob 27 can extend into the first and second slide rails 22 and abut against the side walls of the horizontal and vertical expansion supports 25 and 26. By using the hand-tightening knob 27, the positions of the horizontal and vertical expansion supports 25 and 26 are locked, reducing operational complexity and improving installation efficiency. The sliding adjustment of the horizontal extension bracket 25 and the vertical extension bracket 26 allows for compatibility with various battery specifications, meeting the diverse needs of non-standard drones.

[0038] like Figure 3 As shown, the vertical extension bracket 26 includes a connecting portion 261 and a top plate portion 262. The connecting portions 261 are arranged in pairs and slidably connected within the second slide rail 23. The top plate portion 262 is integrally formed with the two connecting portions 261 and is used to limit the battery pack from above. In this embodiment, the shapes of the connecting portion 261 and the top plate portion 262 are as follows: Figure 3 As shown, the connecting part 261 and the top plate part 262 are L-shaped as a whole, and the top plate part 262 can press down on the top of the battery pack to limit the battery pack.

[0039] like Figure 4 As shown, a limiting plate 251 is bolted to one end of the lateral expansion bracket 25 located inside the sliding groove 24. The limiting plate 251 is positioned below the carbon plate 1. In this embodiment, the limiting plate 251 has the following shape: Figure 4 As shown, the limiting plate 251 is connected to the transverse expansion bracket 25 by bolts. By setting the limiting plate 251, the transverse expansion bracket 25 is further prevented from slipping accidentally, thereby enhancing the stability of the overall structure.

[0040] like Figure 1 As shown, the top of the carbon plate 1 has several through holes 12 for heat dissipation. In this embodiment, the heat dissipation through holes 12 on the carbon plate 1 can effectively reduce the battery operating temperature and extend the battery life.

[0041] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
