Description

Technical Field

[0001] This invention relates to the field of drone battery compartment technology, specifically a drone mechanical battery compartment with shockproof function. Background Technology

[0002] A drone is an aircraft that does not require direct human control and flies through remote control, ground remote controller, preset programs, or artificial intelligence. The drone's battery compartment is a structural component specifically designed to install, fix, and protect the battery pack, directly affecting the drone's endurance, safety, and battery life.

[0003] The endurance and safety of drones depend on the stable operation of the battery. Vibrations during flight, such as rapid acceleration, airflow disturbances, and minor collisions, may cause the battery to loosen, interface to become poorly contacted, or even cause the internal cells of the lithium battery to shift or the separator to break, thus posing a safety hazard.

[0004] Meanwhile, when the drone is moving at high speed, the difference between the external air pressure and the internal air pressure of the drone, as well as the airflow characteristics, make it difficult for air to enter the battery compartment, which in turn leads to insufficient heat dissipation and battery overheating.

[0005] When a drone lands, the airflow below the drone's propellers blows up dust, sand, and moisture from the ground. This dust can easily enter the battery compartment, causing poor contact and oxidation of the battery compartment electrodes, and in severe cases, it may render the battery unusable. Summary of the Invention

[0006] The purpose of this invention is to provide a mechanical battery compartment for drones with shockproof function, so as to solve the problems of battery compartment shaking during drone flight, high battery temperature during high-speed flight, and dust entering the battery compartment when landing.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a mechanical battery compartment for a drone with shockproof function, comprising a shockproof component installed inside the drone body (1), a cooling component installed inside the drone body, and a dustproof component installed inside the drone body.

[0008] The shock-absorbing component includes a gas support rod (3), which is fixedly connected to the inner wall of the UAV body (1). The side of the gas support rod (3) away from the UAV body (1) is fixedly connected to the battery (2). A connecting pipe (301) is provided inside the gas support rod (3), and an air supply pipe (302) is provided inside the gas support rod (3). The side of the air supply pipe (302) away from the gas support rod (3) is provided inside the fixing plate (601).

[0009] The cooling component includes a fixed plate (601), and an air storage box (6) is fixedly connected to the top of the outer surface of the fixed plate (601). An air outlet (603) is provided inside the fixed plate (601).

[0010] The dustproof component includes an air curtain nozzle (602), and the air curtain nozzle (602) is disposed inside the fixed plate (601). The inner wall of the UAV body (1) is fixedly connected to a support column (101), and the side of the support column (101) away from the UAV body (1) is fixedly connected to the fixed plate (601).

[0011] Preferably, a fixed column (402) is fixedly connected to the inner wall of the UAV body (1), and a large rotating frame (401) is rotatably sleeved on the outer surface of the fixed column (402). A second connecting column (406) is rotatably embedded inside the large rotating frame (401), and a large slider (407) is rotatably sleeved on the outer surface of the second connecting column (406).

[0012] Preferably, a slide rod (501) is slidably sleeved on the outer surface of the large slider (407), and a piston (502) is fixedly connected to one side of the outer surface of the slide rod (501).

[0013] Preferably, an air inlet cylinder (5) is fixedly connected to the inner wall of the UAV body (1), the slide rod (501) is slidably embedded inside the air inlet cylinder (5), and the piston (502) is slidably embedded inside the air inlet cylinder (5).

[0014] Preferably, the UAV body (1) is internally fitted with a fan blade (4), and a small rotating frame (403) is fixedly connected to one side of the outer surface of the fan blade (4).

[0015] Preferably, the small rotating frame (403) is rotatably embedded with a first connecting post (404), and the outer surface of the first connecting post (404) is rotatably fitted with a small slider (405), which is slidably embedded inside the large rotating frame (401).

[0016] Preferably, the air inlet cylinder (5) is provided with an air delivery pipe (503), and the side of the air delivery pipe (503) away from the air inlet cylinder (5) is provided inside the connecting pipe (301).

[0017] Preferably, the connecting pipe (301) is inserted into the gap between the battery packs inside the battery (2), and the gas supply pipe (503) is inserted into the gap between the battery packs inside the battery (2).

[0018] Compared with the prior art, the beneficial effects of the present invention are: This invention utilizes multiple air support rods to dynamically adapt to vibration intensity, reducing battery stress damage. When the drone is flying at high speed, the airflow speed increases, the air pressure inside the air support rods rises, and the support force is enhanced. Rigid constraints limit the lateral and longitudinal swaying of the battery, and the support of multiple air support rods prevents the battery from hard colliding with the inner wall of the drone body. When the drone is flying at low speed or hovering, the air pressure in the air support rods decreases, and the support force weakens, avoiding excessive constraint on the battery. The elastic buffer of the air support rods replaces rigid fixation, preventing the battery from accumulating fatigue stress due to long-term hard constraints.

[0019] This invention uses multiple metal corrugated pipes inserted into the gaps between the battery packs inside the battery to directly contact the surface of the battery cells. The airflow directly removes the heat generated by the battery during operation, and the external temperature of the battery is cooled by multiple air outlets. The external cooling and internal cooling work together to prevent the battery temperature from becoming too high.

[0020] When the drone is about to land after completing its work, the invention discharges all the remaining gas in the gas storage tank through the air curtain nozzle and the air outlet. The gas discharged through multiple air curtain nozzles forms an air curtain, which blocks the drone's propeller from blowing dust and impurities from the ground, preventing impurities from entering the battery and adhering to the battery electrode plates.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0024] The present invention provides a mechanical battery compartment for a drone with shockproof function, including a shockproof component installed inside the drone body 1, a cooling component installed inside the drone body 1, and a dustproof component installed inside the drone body 1.

[0025] The shock-absorbing component includes multiple gas struts 3, all of which are fixedly connected to the inner wall of the drone body 1. The side of each gas strut 3 away from the drone body 1 is fixedly connected to a battery 2. Each gas strut 3 has a connecting pipe 301 inside. Multiple fixing posts 402 are fixedly connected to the inner wall of the drone body 1. Large rotating frames 401 are rotatably fitted onto the outer surfaces of each fixing post 402. Second connecting posts 406 are rotatably embedded inside each large rotating frame 401. Large sliders 407 are rotatably fitted onto the outer surfaces of each second connecting post 406. Sliding rods 501 are slidably fitted onto the outer surfaces of each large slider 407. Pistons 50 are fixedly connected to one side of the outer surface of each sliding rod 501. 2; Multiple air inlets 5 are fixedly connected to the inner wall of the UAV body 1, multiple slide rods 501 are slidably embedded inside the air inlets 5, and multiple pistons 502 are slidably embedded inside the air inlets 5; Multiple fan blades 4 are rotatably embedded inside the UAV body 1, and a small rotating frame 403 is fixedly connected to one side of the outer surface of each of the multiple fan blades 4; a first connecting post 404 is rotatably embedded inside each of the multiple small rotating frames 403, and a small slider 405 is rotatably sleeved on the outer surface of each of the multiple first connecting posts 404, and multiple small sliders 405 are slidably embedded inside the large rotating frame 401; an air supply pipe 503 is provided inside each of the multiple air inlets 5, and the side of each air supply pipe 503 away from the air inlets 5 is located inside the connecting pipe 301.

[0026] See Figures 2 to 9 As shown, when the UAV body 1 moves at high speed in the high altitude, the UAV body 1 blows the fan blade 4 to rotate. The rotation of the fan blade 4 drives the small slider 405 to slide inside the large rotating frame 401. The sliding of the small slider 405 drives the large rotating frame 401 to rotate around the fixed column 402. When the large rotating frame 401 rotates around the fixed column 402, it drives the large slider 407 to move. The movement of the large slider 407 drives the slide rod 501 to reciprocate inside the air intake cylinder 5. The reciprocating movement of the piston 502 allows air to enter. The gas is delivered to multiple connecting pipes 301 through the air supply pipe 503 connected to the air intake cylinder 5. The connecting pipes 301 are connected to the air support rod 3. The air support rod 3 is connected to the fixed plate 601 through the air supply pipe 302. The gas is stored in the air storage box 6 through the air intake cylinder 5.

[0027] During the movement of the drone body 1, the battery 2 is buffered by multiple air support rods 3. When the drone body 1 is flying at high speed, the airflow speed increases, the air pressure inside the air support rods 3 increases, and the support force is enhanced. The rigid constraint restricts the lateral and longitudinal swaying of the battery 2. The support of multiple air support rods 3 prevents the battery 2 from having a hard collision with the inner wall of the drone body 1. When the drone body 1 is at low speed or hovering, the air pressure of the air support rods 3 decreases and the support force weakens, avoiding excessive constraint on the battery 2. The elastic buffer of the air support rods 3 replaces rigid fixation, avoiding the accumulation of fatigue stress in the battery 2 due to long-term hard constraint, such as shell cracking and electrode deformation. The above technical solution dynamically adapts to the vibration intensity and reduces stress damage to the battery 2.

[0028] The cooling component includes a fixed plate 601, and an air storage box 6 is fixedly connected to the top of the outer surface of the fixed plate 601. Multiple air outlets 603 are provided inside the fixed plate 601. Multiple air support rods 3 are each provided with an air supply pipe 302 inside, and the side of the multiple air supply pipes 302 away from the air support rods 3 is located inside the fixed plate 601. Multiple connecting pipes 301 are inserted into the gaps between the battery packs inside the battery 2, and multiple air supply pipes 503 are inserted into the gaps between the battery packs inside the battery 2.

[0029] See Figures 3 to 7As shown, when the drone body 1 is under high load, such as during heavy-duty or high-speed maneuvers, the battery 2 has a high temperature. Furthermore, when the drone body 1 is moving at high speed, the air pressure difference and airflow characteristics make it difficult for air to enter the drone body 1 and the battery 2, resulting in insufficient heat dissipation and battery overheating. The gas is controlled by the air storage tank 6 to spray gas through multiple air outlets 603, which cools the outer surface of the battery 2. When the gas is transported from the air inlet 5 to the air storage tank 6, it is transmitted through multiple connecting pipes 301 and air supply pipes 503. The multiple connecting pipes 301 and air supply pipes 503 are all metal corrugated pipes, and they are all inserted in the gaps between the battery packs inside the battery 2, directly contacting the surface of the battery cells. The airflow directly removes the heat generated by the operation of the battery 2. The combination of external and internal cooling prevents the battery 2 from overheating.

[0030] The cooling component includes a fixed plate 601, and an air storage box 6 is fixedly connected to the top of the outer surface of the fixed plate 601. Multiple air outlets 603 are provided inside the fixed plate 601. Air supply pipes 302 are provided inside the multiple air support rods 3, and the side of the multiple air supply pipes 302 away from the air support rods 3 is provided inside the fixed plate 601. See Figures 2 to 4 As shown, when the drone body 1 is about to land after completing its work, all the remaining gas inside the gas storage tank 6 is discharged through the air curtain nozzle 602 and the air outlet 603. The gas discharged through multiple air curtain nozzles 602 forms an air curtain, which blocks dust and impurities blown by the propeller of the drone body 1, preventing impurities from entering the battery 2 and adhering to the battery electrode plates. At the same time, the gas sprayed from the air outlet 603 can also form a second protective air curtain. Through multiple protective air curtains, impurities are blocked. Meanwhile, the fixing plate 601 can also assist in cooling the surface of the battery 2.

[0031] When the drone body 1 moves at high speed in the high altitude, the drone body 1 drives the fan blades 4 to rotate. The rotation of the fan blades 4 drives the slider 501 to reciprocate within the air intake 5 via the crank slider. The reciprocating movement of the slider 501 delivers gas through the air supply pipe 503 to the connecting pipe 301. Both the air supply pipe 503 and the connecting pipe 301 are metal corrugated pipes, and they are inserted into the gaps between the battery packs within the battery 2. The gas flow cools the battery 2. The gas enters multiple air support rods 3 and the air storage tank 6, where it is stored. When the drone body 1 flies at high speed, the air pressure inside the air support rods 3 increases, the support force is enhanced, and the constraint on the battery 2 is strengthened, preventing the battery 2 from swaying laterally and longitudinally. When the drone body 1 is at low speed or hovering, the air pressure in the air support rods 3 decreases, the support force is weakened, and the battery 2 is not over-constrained. The elastic buffer of the air support rods 3 replaces rigid fixation, preventing the battery 2 from being over-constrained. During the high-speed flight of the drone body 1, the gas stored inside the air tank 6 is ejected through multiple air outlets 603. The ejected gas cools the surface of the battery 2. The combination of external and internal cooling through the flow of gas inside and on the surface of the battery 2 prevents insufficient heat dissipation and overheating of the battery 2 due to air pressure differences and airflow characteristics when the drone body 1 moves at high speed. When the drone body 1 is about to land after completing its work, the multiple air support rods 3 are no longer needed to support the battery 2. All the remaining gas inside the air tank 6 is discharged through the air curtain nozzle 602 and the air outlets 603. The gas ejected by the air curtain nozzle 602 forms an air curtain, and the gas ejected by the air outlets 603 also forms an air curtain. At the same time, the air curtain nozzle 602 also cools the battery 2. The two layers of air curtains prevent dust and impurities stirred up by the propeller of the drone body 1 from entering the battery 2, thus protecting the battery 2.

[0032] Working principle: When the UAV body 1 moves at high speed in the high air, the fan blades 4 rotate as the UAV body 1 moves. The rotation of the fan blades 4 drives the small slider 405 to slide inside the large rotating frame 401. The sliding of the small slider 405 drives the large rotating frame 401 to rotate around the fixed column 402. When the large rotating frame 401 rotates around the fixed column 402, it drives the large slider 407 to move. The movement of the large slider 407 drives the slide rod 501 to reciprocate inside the air intake cylinder 5. The reciprocating movement of the piston 502 allows air to enter. The gas is delivered to multiple connecting pipes 301 through the air supply pipe 503 connected to the air intake cylinder 5. The connecting pipes 301 are connected to the air support rod 3. The air support rod 3 is connected to the fixed plate 601 through the air supply pipe 302. The gas is stored in the air storage box 6 through the air intake cylinder 5. During the movement of the drone body 1, the battery 2 is buffered by multiple air support rods 3. When the drone body 1 is flying at high speed, the airflow speed increases, the air pressure inside the air support rods 3 increases, and the support force is enhanced. The rigid constraint restricts the lateral and longitudinal swaying of the battery 2. The support of multiple air support rods 3 prevents the battery 2 from colliding hard with the inner wall of the drone body 1. When the drone body 1 is at low speed or hovering, the air pressure of the air support rods 3 decreases and the support force weakens, avoiding excessive constraint on the battery 2. The elastic buffer of the air support rods 3 replaces the rigid fixation. When the drone body 1 is flying under high load, such as carrying a heavy load or maneuvering at high speed, the battery 2 has a high temperature. When the drone body 1 is moving at high speed, the air pressure difference and airflow characteristics make it difficult for air to enter the drone body 1 and the battery 2, which leads to insufficient heat dissipation and battery overheating. The gas is controlled by the air storage box 6 to spray out through multiple air outlets 603 to cool the outer surface of the battery 2. When the gas is transported from the air inlet 5 to the air storage box 6, it is transmitted through multiple connecting pipes 301 and air supply pipes 503. The multiple connecting pipes 301 and air supply pipes 503 are all metal corrugated pipes, and the multiple connecting pipes 301 and air supply pipes 503 are all inserted in the gaps between the battery packs in the battery 2, directly contacting the surface of the battery cells. The heat generated by the operation of the battery 2 is directly carried away by the airflow. When the drone body 1 is about to land after completing its work, all the remaining gas inside the gas storage tank 6 is discharged through the air curtain nozzle 602 and the air outlet 603. The gas discharged by multiple air curtain nozzles 602 forms an air curtain, which blocks dust and impurities blown by the propeller of the drone body 1 from entering the battery 2 and adhering to the battery electrode plates. At the same time, the gas sprayed by the air outlet 603 can also form a second protective air curtain. Through multiple layers of protective air curtains, impurities are blocked, and the air curtain nozzles 602 can also assist in cooling the surface of the battery 2.
