Technical Field

[0001] This utility model relates to the field of drone power technology, specifically to a drone battery compartment structure. Background Technology

[0002] Unmanned aerial vehicles (UAVs), also known as drones, are unmanned aircraft controlled by radio remote control equipment and onboard program control devices. They have no cockpit but are equipped with autopilots, program control devices, and other equipment. The power supply for UAVs during flight mainly comes from their internal batteries, which have a limited lifespan and therefore need to be replaced periodically. Current UAV batteries and the battery compartments used to install them are too simple in structure, generally fixed with bolts, which makes battery replacement inconvenient, reduces replacement efficiency, and provides poor protection, exposing the batteries directly to the outside and increasing safety risks.

[0003] Therefore, it is necessary to design a drone battery compartment structure that can be easily disassembled, securely connected, facilitates quick power connection, and effectively protects the battery. Utility Model Content

[0004] To address the shortcomings of the aforementioned technologies, this invention provides a battery compartment structure for unmanned aerial vehicles (UAVs).

[0005] The technical solution of this utility model is as follows: A drone battery compartment structure includes a battery housing, a guide rail, and a drone battery. The guide rail includes a mounting groove, a limiting part, a locking groove, and a sliding rail part that are detachably and fixedly connected to the drone frame. The battery housing includes a locking tongue device, a storage cavity for accommodating the drone battery, and an upper guide cover. The storage cavity has a door that can be opened and closed. The upper guide cover has a slot that matches the contour of the sliding rail part. The guide rail enters the upper guide cover along the slot. The limit part stops when it comes into contact with the battery casing. The upper guide cover is provided with a locking groove at the end of the moving path of the locking groove. The locking tongue device is provided in the locking groove and includes a locking tongue, an unlocking button and a transmission mechanism that are mutually driven and cooperated. The locking tongue can elastically extend out of or retract into the locking groove. The locking tongue is elastically retracted into the locking groove when it is abutted by the guide rail. When the locking groove and the locking groove are aligned, the locking tongue elastically extends out into the locking groove, preventing the guide rail from exiting the slot. The unlocking button drives the locking tongue to retract into the locking groove.

[0006] The battery housing also includes a battery plug and a male connector. The battery plug is disposed on the outer surface of the battery housing and is disposed in the storage cavity with the male connector of the drone and is electrically connected to the battery plug. The drone battery is provided with a female connector, and when the drone battery is housed in the storage cavity, the female connector is electrically connected to the male connector.

[0007] Further features of this utility model: The locking groove is L-shaped, including a first opening facing one side of the locking groove and a second opening on the other side. The transmission mechanism includes a fixed seat, a connecting rod, a torsion spring and several pins. One end of the fixed seat is provided with a mounting hole for fixed connection with the upper guide cover, and the other end is provided with a hinge groove for hinge connection with the locking tongue.

[0008] The latch includes a protruding end near the first opening, a first hinge hole near the second opening, and a second hinge hole away from the first and second openings. The second hinge hole is hinged to the hinge groove. The torsion spring is disposed in the hinge groove and works in conjunction with the latch to drive the protruding end to rotate around the second hinge hole toward the direction of protruding from the first opening. The profile of the protruding end is adapted to the profile of the first opening and the latch groove, and the end face facing the insertion direction of the guide rail is a bevel or an arc surface.

[0009] The unlock button is located at the second opening and slides in place. The unlock button has a third hinge hole on the side facing the latch. The two ends of the connecting rod are hinged to the first hinge hole and the third hinge hole, respectively. The unlock button slides towards the latch, driving the latch to flip away from the first opening.

[0010] A further feature of this invention is that the battery housing also includes a rotary lock. The end of the compartment door away from the upper guide cover is hinged to the opening of the storage cavity. The rotary lock includes a rotating part and a locking arm. The rotating part rotates with the upper guide cover, and the locking arm rotates around the rotating part into one side of the opening of the storage cavity and prevents the compartment door from leaving the opening of the storage cavity.

[0011] A further feature of this invention is that the knob lock and the unlock button are located on the same end face.

[0012] A further feature of this invention is that the battery housing also includes a frame component and several carbon plate components. The frame component includes a top surface, a bottom surface, and four side surfaces. The top surface is provided with several first screw holes for connection to the upper guide cover. The bottom surface and the four side surfaces are provided with several second screw holes for connection to the carbon plate components. The several carbon plate components are screwed together with the frame component to form a closed battery housing.

[0013] A further feature of this invention is that the limiting portion of the guide rail extends in an L-shape, the guide rail is provided with a weight-reducing groove, and the insertion slide rail portion is located on both sides of the guide rail in the width direction.

[0014] The beneficial effects of this utility model are as follows: the guide rail is pre-installed on the drone frame, and the battery housing can be quickly plugged in. When the battery needs to be replaced, press the unlock button, slide it towards the side of the locking tongue, drive the locking tongue to flip away from the first opening, so that the locking tongue leaves the locking groove and retracts into the locking groove. The upper guide cover can then be separated from the guide rail, the battery housing can be removed, and the knob lock can be rotated so that the locking arm no longer obstructs the opening of the compartment door.

[0015] Conversely, when installing the battery housing onto the guide rail, directly align it with the slide rail part and insert it into the slot. The lock slot moves to coincide with the locking groove position. The contact of the front end first presses the lock tongue into the first opening of the locking groove. Then, under the action of the torsion spring, the lock tongue will automatically flip into the lock slot, preventing the guide rail from leaving the slot.

[0016] Further design modifications include a battery plug, male connector, and female connector to facilitate connection between the battery inside the battery housing and the drone's power motherboard wiring, allowing the battery housing to completely enclose and protect the battery. Existing technologies such as the XT90 model can be used for the connector module. Attached Figure Description
