Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle (UAV) airborne power supplies, in particular to an anti-condensation UAV airborne power supply. Background Art

[0002] The drone's onboard power supply is referred to as a battery. The battery can be portable and replaced. When the drone is flying at high altitude, when the battery surface temperature is lower than the surrounding air temperature, the water vapor will condense into water droplets when it encounters cold, resulting in condensation on the outer surface of the drone's onboard power supply. In spring, summer and autumn, the weather temperature is relatively high. When the drone is flying, its internal onboard battery is prone to heat up in the process of continuously powering the drone. At this time, the outer surface of the heated onboard battery is not easy to condense. In winter, even if the onboard power supply continues to run, it is difficult to heat up, which causes the battery surface temperature to be lower than the surrounding air temperature, thus causing the condensation problem;

[0003] According to experiments, when a drone is flying at high altitude, once condensation occurs on the outside of the onboard battery, the dew droplets can easily penetrate into the inside of the battery, which can easily lead to damage to battery performance, shortened battery life and circuit short circuit. Therefore, it is necessary to provide a condensation-proof drone onboard power supply to solve the above technical problems. Utility Model Content

[0004] The purpose of the utility model is to provide an anti-condensation UAV airborne power supply to solve the problem proposed in the above background technology that when the UAV is flying at high altitude, once condensation occurs on the outside of the airborne battery, the dew droplets can easily penetrate into the inside of the battery, which can easily lead to damage to battery performance, shortened battery life and circuit short circuit. The technical solution of the utility model is aimed at the technical problem that the existing technical solution is too single, and provides a solution that is significantly different from the existing technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-condensation UAV airborne power supply, comprising a power supply housing, a mounting slot, an airborne power supply body, a heating wire and a micro power supply, the airborne power supply body being mounted on the inner side of the power supply housing via an insulating bracket, and heating wires capable of heating the outer side thereof are distributed on the inner wall of the power supply housing, a micro power supply is arranged on one side inside the power supply housing, and a connector is installed on the output end of the micro power supply, a pressure rod is installed above the power supply housing, and telescopic buckles are arranged on both sides of the pressure rod.

[0006] In a further embodiment, a mounting groove is provided on the top of the power supply housing, and the mounting groove and the telescopic buckle form a clamping structure, and a first spring is connected to the inner side of the telescopic buckle.

[0007] In a further embodiment, both ends of the heating wire are connected to the same circuit.

[0008] In a further embodiment, a second spring is clamped on the outer side of the pressure rod, and a pressure block is connected to the outer side below the pressure rod, a conductor is inserted into the inner side of the pressure block, and the pressure block is made of insulating material.

[0009] In a further embodiment, the connector and the conductor form a sealed lifting and sliding structure.

[0010] In a further embodiment, the conductor is connected to one end of the line.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The utility model, when flying a drone in winter, uses the provided pressure rod, second spring, pressure block and conductor to manually press the pressure rod in cooperation with the second spring, so that the telescopic buckle is effectively engaged with the first spring to be clamped into the card slots on both sides, and at the same time, the pressure block and the conductor can be effectively driven to move downward, and then can be inserted into the inner side of the connector, and connected to the micro power supply, so that the heating wire and the circuit form a current loop, at which time the heating wire will be heated by the current and higher than the maximum temperature of the winter dew point. Compared with the existing technology, the power supply housing can be effectively heated to the maximum temperature of the winter dew point, thereby preventing the problem of condensation on the outer surface of the onboard power supply, and at the same time avoiding the phenomenon of damaged battery performance, shortened battery life and circuit short circuit;

[0013] 2. According to the utility model, when the drone is flown in spring, summer and autumn, the pressure rod, the second spring, the pressure block and the conductor are arranged. Before the drone takes off, the pressure rod can be quickly pressed manually. At this time, the pressure rod will cooperate with the second spring to push it upward, so that the telescopic buckle cooperates with the contraction of the first spring to quickly separate from the card slot and move upward. When the pressure rod moves upward, it can also drive the pressure block and the conductor to move upward at the same time. Compared with the existing technology, this makes the conductor separated and disconnected from the connector, so that the current is disconnected and the heating wire cannot be heated.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3 The utility model provides an embodiment: an anti-condensation UAV airborne power supply, including a power supply shell 1, a mounting groove 101, an airborne power supply body 2, a heating wire 3 and a micro power supply 4, the airborne power supply body 2 is installed on the inner side of the power supply shell 1 through an insulating bracket, and the inner wall of the power supply shell 1 is distributed with a heating wire 3 that can heat the outer side thereof, a micro power supply 4 is arranged on one side inside the power supply shell 1, and a connector 5 is installed on the output end of the micro power supply 4, a pressure rod 6 is installed above the power supply shell 1, and telescopic buckles 7 are arranged on both sides of the pressure rod 6. Example 1

[0020] See also Figure 1-3 A mounting groove 101 is provided on the top of the power supply housing 1, and the mounting groove 101 and the telescopic buckle 7 form a clamping structure, a first spring 701 is connected to the inner side of the telescopic buckle 7, both ends of the heating wire 3 are connected to the same line 301, a second spring 601 is clamped on the outer side of the pressure rod 6, and a pressure block 602 is connected to the outer side below the pressure rod 6, a conductor 603 is inserted into the inner side of the pressure block 602, and the pressure block 602 is made of insulating material, the connector 5 and the conductor 603 form a sealed lifting and sliding structure, and the conductor 603 is connected to one end of the line 301;

[0021] When flying a drone in winter, the temperature of the battery shell is lower than the ambient temperature due to the extremely cold weather. This can easily cause condensation on the battery shell, which can seriously affect the battery performance, service life, and circuit failure.

[0022] To solve the above problem, before the UAV is flown, the pressure rod 6 is manually pressed in cooperation with the second spring 601, so that the telescopic buckle 7 is engaged with the first spring 701 and is inserted into the slots on both sides. When the pressure rod 6 moves downward, it can also drive the pressure block 602 and the conductor 603 to move downward. By moving the conductor 603 downward, it can be inserted into the inner side of the connector 5 and connected to the micro power supply 4, so that the heating wire 3 and the line 301 form a current loop. At this time, the heating wire 3 will be heated by the current and higher than the maximum dew point temperature in winter, so that the temperature of the power supply housing 1 is increased. After searching, the maximum dew point temperature in winter is usually below 25°C, so the heating temperature of the heating wire is between 26°C and 30°C, so that the temperature of the power supply housing 1 is maintained between 26°C and 30°C. This temperature is below the normal temperature of the human body and is not enough to affect the normal operation of the onboard power supply body 2. Example 2

[0023] See also Figure 1-3 , which is different from the first embodiment: a first spring 701 is connected to the inner side of the telescopic buckle 7, two ends of the heating wire 3 are connected to the same line 301, a second spring 601 is clamped on the outer side of the pressure rod 6, and a pressure block 602 is connected to the outer side below the pressure rod 6, a conductor 603 is inserted into the inner side of the pressure block 602, and the pressure block 602 is made of insulating material, the connector 5 and the conductor 603 form a sealed lifting and sliding structure, and the conductor 603 is connected to one end of the line 301;

[0024] When flying the drone in spring, summer and autumn, the onboard battery will generate heat when powered, and the heat will also be conducted to the power supply housing 1, which makes the temperature of the outer surface of the power supply housing 1 necessarily higher than the temperature of the surrounding environment. Therefore, there is no need to heat the heating wire 3. Here, the method of disconnecting the current of the heating wire 3 is as follows:

[0025] Before the drone takes off, the pressure rod 6 can be pressed quickly and manually. At this time, the pressure rod 6 will cooperate with the second spring 601 to push it upward, so that the telescopic buckle 7 cooperates with the contraction of the first spring 701 to quickly separate from the card slot and move upward. When the pressure rod 6 moves upward, it can also drive the pressure block 602 and the conductor 603 to move upward at the same time, so that the conductor 603 is separated and disconnected from the connector 5, so that the current is disconnected and the heating wire 3 cannot be heated.

[0026] Working principle: Figure 1-3 As shown, when flying a drone in winter, the temperature of the battery shell is lower than the ambient temperature due to the extremely cold weather, which causes condensation on the battery shell, seriously affecting the battery performance, service life and circuit failure.

[0027] In order to solve the above problem, before the UAV is flown, the pressure rod 6 is first manually pressed in cooperation with the second spring 601, so that the telescopic buckle 7 is engaged with the first spring 701 and is inserted into the card slots on both sides. When the pressure rod 6 moves downward, it can also drive the pressure block 602 and the conductor 603 to move downward. By moving the conductor 603 downward, it can be inserted into the inner side of the connector 5 and connected to the micro power supply 4, so that the heating wire 3 and the line 301 form a current loop. At this time, the heating wire 3 will be heated by the current and higher than the maximum temperature of the winter dew point, so that the temperature of the power supply housing 1 is increased. After searching, the maximum temperature of the winter dew point is usually below 25°C, so the heating temperature of the heating wire is between 26°C and 30°C, so that the temperature of the power supply housing 1 is maintained between 26°C and 30°C. This temperature is below the normal temperature of the human body and is not enough to affect the normal operation of the airborne power supply body 2.

[0028] When flying the drone in spring, summer and autumn, the onboard battery will generate heat when powered, and the heat will also be conducted to the power supply housing 1, which makes the temperature of the outer surface of the power supply housing 1 necessarily higher than the temperature of the surrounding environment. Therefore, there is no need to heat the heating wire 3. Here, the method of disconnecting the current of the heating wire 3 is as follows:

[0029] Before the drone takes off, the pressure rod 6 can be pressed quickly and manually. At this time, the pressure rod 6 will cooperate with the second spring 601 to push it upward, so that the telescopic buckle 7 cooperates with the contraction of the first spring 701 to quickly separate from the card slot and move upward. When the pressure rod 6 moves upward, it can also drive the pressure block 602 and the conductor 603 to move upward at the same time, so that the conductor 603 is separated and disconnected from the connector 5, so that the current is disconnected and the heating wire 3 cannot be heated.
