Description
Technical Field
[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to a lithium battery for an induction aircraft. Background Art
[0002] Sensor-based remote-controlled drone aircraft are widely used in various fields, including agricultural monitoring, environmental testing, film and television shooting, logistics and transportation, etc., and the power source of these aircraft mainly relies on lithium batteries. As the core power system of drones, lithium batteries provide the required electrical energy for the electric motor to ensure that the drone can take off, fly and land smoothly. The flight time, range and load capacity of the drone are directly related to the performance of the battery. The working principle of this type of lithium battery is mainly based on the embedding and de-embedding process of lithium ions. When charging, the external power supply applies voltage to the battery, and the lithium ions are separated from the positive electrode material, move to the negative electrode through the electrolyte, and embed in the negative electrode material. This process is accompanied by the flow of electrons from the external circuit to the negative electrode. During the discharge process, the lithium ions are separated from the negative electrode, return to the positive electrode through the electrolyte, and release energy for use by the drone's motor. At the same time, electrons flow from the negative electrode through the external circuit to the positive electrode, forming an electric current, which provides power for the drone;
[0003] For example, the shockproof and explosion-proof lithium battery pack for drones disclosed in authorization publication number CN220544101U includes a housing and lithium batteries. The housing has an opening on one side, and lithium batteries are inserted and installed inside the housing. Vertical shock absorbers are fixedly installed on the upper and lower sides of the housing, and horizontal shock absorbers are fixedly installed on the left and right sides of the housing. Buffer devices are fixedly installed between the multiple lithium batteries. The buffer devices prevent the multiple lithium batteries from colliding with each other. The vertical and horizontal shock absorbers cushion the impact, thereby preventing the lithium battery pack from vibrating violently when the drone hits the ground, thereby extending the service life of the lithium battery pack. However, during the implementation of the above technical solution, the lithium battery still uses a plug to connect to the socket on the drone to form an electrical connection. However, during flight, the drone may experience rapid acceleration, deceleration, and turning movements. At this time, the lithium battery, under the action of inertia, moves with the drone's battery socket, resulting in an unstable connection and intermittent power supply interruptions. This is particularly dangerous during flight and can easily cause the drone to lose power at high altitude and crash. Utility Model Content

DETAILED DESCRIPTION
[0020] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0021] See also Figure 1-7 The utility model provides an embodiment: a lithium battery for an induction aircraft, comprising a drone body 1 and a power socket 3 installed on one side of the bottom end of the drone body 1, two mirror-symmetrical trapezoidal hollow shells 5 are installed at the bottom end of the drone body 1, a lithium battery cell 2 for plugging into and maintaining electrical connection with the power socket 3 is installed between the two trapezoidal hollow shells 5, and an embedded groove 4 is provided on the left and right outer walls of the lithium battery cell 2, an annular hollow sleeve 6 is rotatably installed at the center position of the bottom of the trapezoidal hollow shell 5, the bottom end of the annular hollow sleeve 6 passes through the outside of the trapezoidal hollow shell 5 and is installed with a fan-shaped clamping plate 7, the fan-shaped clamping plate 7 is screwed into the embedded groove 4, an I-shaped sliding arm 8 is slidably installed on one side of the interior of the trapezoidal hollow shell 5, and a baffle 801 is fixed at one end of the I-shaped sliding arm 8, and the baffle 801 is made of a rubber component;
[0022] A gear rack rotating structure 11 is provided on one side outer wall of the I-shaped slide arm 8 for driving the annular hollow sleeve 6 to rotate, and an elastic reset structure 9 is provided on one side inner wall of the trapezoidal hollow shell 5 for forcing the I-shaped slide arm 8 to move out of the trapezoidal hollow shell 5;
[0023] The gear rack rotating structure 11 includes a hollow gear ring 1102 rotatably mounted at the bottom end of the drone body 1 and a tooth groove 1101 provided on the outer wall of one side of the I-shaped sliding arm 8. The tooth groove 1101 and the hollow gear ring 1102 are meshed with each other. The bottom end of the hollow gear ring 1102 is fixedly connected to the top end of the annular hollow sleeve 6. Vertical rods 1103 are fixed on both sides of the bottom end of the hollow gear ring 1102. The bottom end of the vertical rod 1103 is fixedly connected to the top edge of the annular hollow sleeve 6.
[0024] When the lithium battery cell 2 needs to be removed from the drone body 1, the user manually pushes the I-shaped sliding arm 8 toward the inner side of the trapezoidal hollow shell 5, and the I-shaped sliding arm 8 drives the hollow gear ring 1102 to rotate through the tooth groove 1101, and then the hollow gear ring 1102 drives the annular hollow sleeve 6 and the fan-shaped clamping plate 7 to rotate through the vertical rod 1103, and then the fan-shaped clamping plate 7 is screwed out of the outside of the embedded groove 4, thereby disconnecting the embedded connection between the fan-shaped clamping plate 7 and the lithium battery cell 2, and the user can normally pull out the lithium battery cell 2 from the power socket 3. The operator only needs to screw in or out the fan-shaped clamping plate 7 to easily take out or put in the lithium battery. This design not only improves the efficiency of battery replacement, but also reduces the risk of damage caused by frequent operations;
[0025] A triangular arm 10 is fixed to the bottom of the trapezoidal hollow shell 5, and the upper surface of the triangular arm 10 is slidably fitted with the lower surface of the I-shaped sliding arm 8;
[0026] The elastic reset structure 9 includes a triangular seat installed on the inner wall of one side of the trapezoidal hollow shell 5, a coil spring installed on the outer wall of one side of the triangular seat, and a sink cavity arranged inside the I-shaped slide arm 8. One end of the coil spring extends to the inside of the sink cavity and is fixedly connected to the inner wall of one side of the sink cavity. When the I-shaped slide arm 8 is no longer subjected to external force, the coil spring in the elastic reset structure 9 forces the I-shaped slide arm 8 to move outward, thereby causing the gear rack rotation structure 11, the annular hollow sleeve 6, and the sector clamping plate 7 to move in the opposite direction, causing the sector clamping plate 7 to reset and wait for the next battery connection.
[0027] When the embodiment of the present application is in use, first, the lithium battery cell 2 is accurately placed in a predetermined position between the two trapezoidal hollow shells 5. The shape of the trapezoidal hollow shell 5 enables it to firmly wrap the two sides of the battery cell, providing a solid support structure. Its trapezoidal design helps to withstand lateral forces from all directions during flight, ensuring that the lithium battery cell 2 will not be displaced due to inertia during flight. After the lithium battery cell 2 is placed between the two trapezoidal hollow shells 5, the tail end plug of the lithium battery cell 2 is connected to the power socket 3 of the drone body 1. The electrical connection between the plug and the socket is the key to battery power supply and can transmit the battery's electrical energy to various systems of the drone. Before this, the user needs to manually push the I-shaped slide arm 8 toward the inside of the trapezoidal hollow shell 5 so that the I-shaped slide arm 8 gradually sinks into the trapezoidal hollow shell 5. The linear motion of the I-shaped slide arm 8 is converted into the annular hollow sleeve 6 through the gear rack rotating structure 11. The rotation of the fan-shaped card plate 7 causes the two fan-shaped card plates 7 to swing toward each other until the large end of the fan-shaped card plate 7 swings to the outside of the drone to avoid the fan-shaped card plate 7 blocking the connection of the trapezoidal hollow shell 5 and the lithium battery cell 2. When the battery plug is connected to the socket, the user releases the I-shaped slide arm 8, and the elastic action of the elastic reset structure 9 forces the I-shaped slide arm 8 to move out of the trapezoidal hollow shell 5, and the gear rack rotation structure 11 forces the annular hollow sleeve 6 and the fan-shaped card plate 7 to reset. At this time, the fan-shaped card plate 7 is screwed in and engaged with the embedded groove 4 on the outer wall of the lithium battery cell 2. The embedded structure can effectively prevent the lithium battery cell 2 from moving back and forth, ensuring the stable position of the battery during flight. At this time, the connection between the lithium battery cell 2 and the drone body 1 can work stably and reliably, improving the connection stability between the battery and the drone body, reducing the risk of power connection interruption, and ensuring that the drone can fly stably.
