Technical Field

[0001] This utility model relates to the technical field of battery fixing, and in particular to a lithium battery fixing device for model aircraft. Background Technology

[0002] With the continuous development of society and the advancement of science, model aircraft are a rapidly developing new concept of aircraft. They are widely used due to their characteristics such as maneuverability, fast response speed, no need for manual piloting, low operational requirements, and ability to carry various small devices or objects. Most small model aircraft use batteries as their power source, and the battery plays a crucial role. Existing technology announcement CN207116536U proposes a UAV battery fixing device, including a battery fixing box. The bottom of the battery fixing box has a heat dissipation base plate covering the bottom of the battery fixing box. Inside the battery fixing box is a support column embedded in the battery fixing box and fixedly connected to the battery fixing box by bolts. A battery fixing crossbeam is provided on one side of the support column and embedded in the battery fixing box. This UAV battery fixing device is flexible in use, has low manufacturing cost, and has broad application prospects. However, its fixing effect on lithium batteries is poor, making it inconvenient to disassemble and replace lithium batteries. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a lithium battery fixing device for model aircraft that clamps and fixes lithium batteries to ensure stability during use and facilitates disassembly and replacement.

[0004] This utility model discloses a lithium battery fixing device for model aircraft, comprising a battery compartment, a mounting plate, an ejector component, a locking component, and a clamping component. The mounting plate is installed inside the battery compartment via the ejector component. A locking component is installed at the bottom of the mounting plate, and a clamping component is installed at the top of the mounting plate. The battery compartment is installed inside the model aircraft, and the lithium battery is clamped and fixed by the clamping component. The ejector component can eject the mounting plate from the battery compartment when replacing the lithium battery, facilitating disassembly and replacement. At the same time, the locking component can fix the mounting plate inside the battery compartment, ensuring stability during use.

[0005] Preferably, the ejection component includes two sets of guide rods, two sets of push sliders, and two sets of springs. Multiple ejection grooves are formed on the inner walls of the left and right ends of the battery compartment. Guide rods are installed in the ejection grooves, and push sliders are slidably mounted on the outer walls of the guide rods. The left and right ends of the mounting plate are respectively connected to the push sliders. Springs are fitted on the outer walls of the guide rods, with the top of the springs connected to the top of the ejection grooves and the bottom of the springs connected to the top of the push sliders. The spring force pulls the push sliders to slide on the guide rods, thereby pushing the mounting plate upwards in the battery compartment and ejecting the lithium battery from the battery compartment, facilitating disassembly and replacement and enhancing practicality.

[0006] Preferably, the locking components include a mounting post, a locking head, a sliding ring, two sliding rods, two push plates, two locking springs, and two limiting pins. The mounting post is installed at the bottom of the mounting plate, and a locking head is installed at the bottom of the mounting post. A sliding ring is slidably fitted onto the upper part of the locking head. The sliding ring is frustoconical in shape. A recessed groove is provided at the top of the locking head that connects to the bottom of the sliding ring. A locking groove matching the locking head is provided at the bottom of the battery compartment. Storage cavities are provided on the left and right sides of the locking groove. Push plates are slidably installed in the storage cavities, and a sliding rod is coaxially installed at one end of the push plate. The sliding rod slides through the storage cavity and is fitted with a limit locking pin. A locking spring is fitted on the outside of the sliding rod, with one end of the locking spring connected to the push plate and the other end connected to the inner wall of the storage cavity. When the mounting plate is pushed downward, the mounting plate drives the locking head into the locking groove through the mounting post. The locking spring pushes the two limit locking pins to limit and lock the locking head, ensuring stability during use. Pressing the mounting plate again moves the sliding ring below the limit locking pins, and the sliding ring releases the limit locking pins from limiting the locking head, allowing the mounting plate to move upward.

[0007] Preferably, the clamping component includes two transverse slide rods, two clamping sliders, two clamping springs, and two clamping seats. The top of the mounting plate has symmetrically arranged clamping grooves. The transverse slide rods are installed within the clamping grooves, and the clamping sliders are slidably mounted on the outer wall of the transverse slide rods. A clamping seat is installed on the top of the clamping slider, and a positioning groove is formed on the inner wall of the clamping seat. The clamping springs are fitted onto the outer wall of the transverse slide rods, with one end connected to the clamping slider and the other end connected to the inner wall of the clamping groove. Pulling the two clamping seats places the lithium battery into the positioning groove between the two clamping seats. The clamping springs pull the clamping sliders to slide on the transverse slide rods, thus fixing and clamping the lithium battery in place.

[0008] Preferably, it also includes two sets of guide sliders. Guide grooves are symmetrically opened on the left and right sides of the top of the mounting plate about the clamping groove. Guide sliders are symmetrically installed at the front and rear ends of the bottom of the clamping seat. The guide sliders are slidably installed in the guide grooves. When the clamping seat moves, it drives the guide sliders to slide in the guide grooves, which limits and guides them, enhances the connection strength, and ensures stability.

[0009] Preferably, it also includes a strapping strap, which is installed on the top of the mounting plate and has Velcro on the upper part; after the lithium battery is placed between the two clamps, the strapping strap is wrapped around the middle of the lithium battery, and the lithium battery is fixed by the Velcro and the strapping strap to further ensure stability.

[0010] Compared with the prior art, the advantages of this utility model are as follows: the battery compartment is installed inside the model aircraft, the lithium battery is clamped and fixed by the clamping component, the ejection component can push the mounting plate out of the battery compartment when replacing the lithium battery, which is convenient for disassembly and replacement, and the locking component can fix the mounting plate inside the battery compartment to ensure stability during use.
