Description

Technical Field

[0001] The present application relates to the field of battery detection technology, and specifically to a high and low temperature detection device and detection method for a UAV battery. Background Art

[0002] UAV, also known as unmanned aircraft, remote-controlled aircraft or flying robot, is an unmanned aircraft controlled by radio remote control equipment and self-contained program control device. Among them, the battery is an important part of the UAV, which provides the energy required for the UAV to fly. UAV batteries are mainly divided into two categories: lithium-ion batteries and lithium polymer batteries;

[0003] In order to ensure the safety and reliability of the batteries used in drones, they need to be subjected to high and low temperature simulation tests;

[0004] For example, the patent with publication number CN207424221U specifically discloses a battery high and low temperature test box, which performs high temperature and low temperature tests on the battery through a high temperature tester in a separate high temperature test area and a low temperature tester in a separate low temperature test area, and timely dissipates heat from the high temperature test area through heat dissipation ports and dustproof nets to prevent excessive heat accumulation in the high temperature test area, which affects the normal use of the high temperature tester. At the same time, the condensed water droplets generated by the low temperature tester during operation are absorbed through a heat preservation pad and a dry fluff head to prevent the liquefied water in the air from damaging the low temperature tester.

[0005] However, in the implementation of the above patent, the battery can only be tested at one angle during the test. Since the drone has different flight states during flight, the angle of the drone battery in the air is also different. For example, in actual flight, the battery may be in a tilted or inverted state, which will affect the distribution of the electrolyte inside the battery and the contact of the electrodes. In the static single-angle test, it is impossible to simulate such complex state changes.

[0056] Meanwhile, a refrigeration component 3 is arranged inside the lower chamber 31, and the refrigeration component 3 is used to simulate a low temperature environment;

[0057] like Figure 4 As shown, the refrigeration assembly 3 includes a refrigeration cabinet 32 ​​fixedly installed inside the lower chamber 31. The refrigeration cabinet 32 ​​is a prior art, such as the refrigeration structure mentioned in the patent with publication number CN214406628U. At the same time, a lower installation cavity 33 is provided on one side of the chassis 1. The lower installation cavity 33 is used to install the equipment used by the refrigeration structure;

[0058] It should be noted that an opening (not shown in the figure) is provided on the top of the refrigerating cabinet 32 ​​so that subsequent equipment can enter the interior of the refrigerating cabinet 32 ​​through the opening;

[0059] Meanwhile, a carrying assembly 4 is arranged inside the chassis 1, and the carrying assembly 4 is used to place the battery to be tested;

[0060] like Figure 1-Figure 3 As shown, the bearing assembly 4 includes two sets of screw rods 42 rotatably mounted inside the chassis 1, and the screw rods 42 penetrate the partition 26 and are located in the upper cavity 21 and the lower cavity 31, and the bottom of the screw rods 42 is connected to a driving device (not shown in the figure), such as a driving motor and a hydraulic motor, and the driving device is installed inside the lower cavity 31, so that the screw rods 42 are driven to rotate by the driving device, and the driving device is connected to the PLC system;

[0061] At the same time, a closing plate 41 is threadedly mounted on the screw rod 42, and a plurality of guide rods 43 are fixedly mounted inside the chassis 1, so that when the screw rod 42 rotates, the closing plate 41 moves up and down on the screw rod 42, and the closing plate 41 is movably sleeved on the guide rod 43, and then when the screw rod 42 drives the closing plate 41 to move up and down, under the action of the guide rod 43, its moving direction is limited;

[0062] At the same time, a plurality of connecting rods 45 are fixedly installed at the bottom of the closing plate 41, and a bottom plate 46 is fixedly installed at the bottom of the connecting rods 45. At the same time, a carrying plate 44 is fixedly installed on the connecting rods 45. The carrying plate 44 is used to place the battery to be tested, and when the closing plate 41 moves up and down, the bottom plate 46 and the carrying plate 44 can be driven to move up and down synchronously through the connecting rods 45;

[0063] At the same time, a through slot 27 adapted to the carrying plate 44 is opened on the partition plate 26, so that the carrying plate 44 can pass through the through slot 27;

[0064] Continue to refer Figure 3 It should be noted that the closing plate 41 has a flat plate for closing the through groove 27, and a convex plate adapted to the through groove 27 is provided at the bottom of the flat plate to engage and close the through groove 27 to further improve the sealing performance, and the bottom plate 46 has a base plate adapted to the opening of the refrigeration cabinet 32 ​​to block the refrigeration cabinet 32 ​​to prevent most of the cold air from overflowing, and a convex platform adapted to the through groove 27 is provided on the top of the base plate to close the through groove 27;

[0065] Continue to refer Figure 1An air outlet pipe 101 is provided on the top of the chassis 1, and the air outlet pipe 101 passes through the chassis 1, the outer shell 22 and the inner shell 23, and the air outlet pipe 101 is controlled by a solenoid valve (not shown in the figure), so that after the heating component 2 is used, the air outlet pipe 101 is opened by the solenoid valve to dissipate heat from the inner shell 23 in time, and a heat dissipation fan 102 is provided on the chassis 1, and a pipe (not shown in the figure) is provided at the output end of the heat dissipation fan 102, and the pipe passes through the outer shell 22, and a plurality of groups of mesh holes (not shown in the figure) are provided on the inner shell 23, so as to introduce air between the outer shell 22 and the inner shell 23, and allow the air to enter the inner shell 23 through the mesh holes, thereby further improving the heat dissipation effect, so that the temperature in the inner shell 23 is restored to normal temperature;

[0066] In the initial state, the base plate on the bottom plate 46 is located at the opening of the refrigerator 32 to block the cold air in the refrigerator 32 and prevent most of the cold air from escaping. At this time, the boss on the bottom plate 46 is located inside the through groove 27 to further improve the sealing effect. At the same time, the bearing plate 44 is located in the inner shell 23, so that the staff can place the battery to be tested;

[0067] In summary, when testing the battery, the temperature-insulating door of the upper chamber 21 is opened, the battery to be tested is placed on the carrying plate 44, and the heating device is started to heat the inner shell 23, so that the external environment of the battery to be tested can be simulated at high temperature. The battery is then left to stand in the high-temperature environment for a period of time, and the driving device is started to drive the screw rod 42 to rotate, and the screw rod 42 drives the closing plate 41 to move downward, and then synchronously drives the bottom plate 46 and the carrying plate 44 to move downward through the connecting rod 45, thereby driving the battery located on the carrying plate 44 to move toward the inside of the refrigeration cabinet 32;

[0068] During the movement of the closing plate 41, the moving direction is fixed under the action of the guide rod 43 until the convex plate on the closing plate 41 is located in the through groove 27 and the flat plate on the closing plate 41 is in contact with the partition 26. At this time, the supporting plate 44 is located inside the refrigeration cabinet 32 ​​for low-temperature testing. It should be noted that this test can cycle the battery from high temperature to low temperature or from low temperature to high temperature for testing. When the test is completed, the air outlet pipe 101 and the cooling fan 102 are opened to dissipate the heat of the inner shell 23, and the battery is left to stand for a period of time. Then, the supporting assembly 4 is driven to transport the battery to be tested to the inner shell 23, and it is left to stand for a period of time to restore it to normal temperature and taken out. Then, the performance of the battery after high and low temperature thermal shock is measured by measuring equipment.

[0069] Embodiment 2: Although the above embodiment can perform high and low temperature tests on the battery, the battery can only be tested at one angle during the test. Since the drone has different flight states during flight, the angle of the drone's battery in the air is also different. For example, in actual flight, the battery may be in a tilted or inverted state, which will affect the distribution of the electrolyte inside the battery and the contact of the electrodes.

[0070] In order to solve this problem, an adjustment component 5 is provided on the bearing component 4, and the adjustment component 5 is used to adjust the angle of the battery during high and low temperature tests;

[0071] like Figure 2 and Figure 6-Figure 9 As shown, the adjustment assembly 5 includes a cover plate 51 fixedly mounted on the connecting rod 45, and the cover plate 51 is located below the bearing plate 44, and a mounting box 52 is fixedly mounted on the cover plate 51, and a servo motor 53 is fixedly mounted on one side of the mounting box 52, and a screw rod 63 is fixedly mounted on the output end of the servo motor 53, and the bearing of the screw rod 63 is mounted inside the mounting box 52, so that the screw rod 63 rotates inside the mounting box 52 under the drive of the servo motor 53;

[0072] Continue to refer Figure 7 A slide rail 68 is fixedly installed inside the installation box 52, and the slide rail 68 is located below the screw rod 63. A slider 6 is slidably arranged on the slide rail 68, and a rotating drum 61 is rotatably installed inside the slider 6, and the rotating drum 61 is threadedly installed on the screw rod 63;

[0073] Continue to refer Figure 8-Figure 9 A vertical groove 601 is provided inside the slider 6, and an insert block 605 is slidably provided inside the vertical groove 601. Two sets of springs 602 are provided between the top of the insert block 605 and the vertical groove 601. A slot (not shown in the figure) adapted to the insert block 605 is provided on the rotating cylinder 61, and part of the insert block 605 is located inside the slot;

[0074] When the screw 63 rotates, the insert block 605 is located inside the slot, so that the slider 6 and the drum 61 are connected to drive the drum 61 and the slider 6 to move along the axis of the screw 63, and under the action of the slide rail 68, the moving directions of the drum 61 and the slider 6 are restricted;

[0075] Continue to refer Figure 6-Figure 7A top plate 510 is fixedly installed on the top of the installation box 52, and a second clamping plate 56 is fixedly installed on the top plate 510, and a rotating rod 57 is rotatably installed on the second clamping plate 56, and the rotating rod 57 passes through the second clamping plate 56, and a disc 571 is fixedly sleeved on one end of the rotating rod 57, and two groups of openings are penetrated on the top plate 510, and the two ends of the slider 6 are located inside the two groups of openings, and the first clamping plate 54 is fixedly installed on both ends of the slider 6, and a rotating disk 55 is rotatably installed on the first clamping plate 54;

[0076] When the slider 6 moves, the first clamping plate 54 and the rotating disk 55 are synchronously driven to move toward the second clamping plate 56, so that the battery to be tested can be placed between the disk 571 and the rotating disk 55 to be clamped.

[0077] Continue to refer Fig. 9 A slide groove 603 is provided inside the slider 6, the slide groove 603 is connected to the vertical groove 601, and a moving block 604 is slidably provided inside the slide groove 603, the moving block 604 is located on one side of the insert block 605, and an oblique groove 607 is penetrated on the moving block 604, and a short rod 606 is connected to one end of the insert block 605, and one end of the short rod 606 penetrates the oblique groove 607;

[0078] For the convenience of explanation, Fig. 9 In the figure, the inclined slot 607 is divided into a left end and a right end from left to right, and the inclined slot 607 gradually rises along the direction from the left end to the right end. In the initial state, the short rod 606 is located at the left end;

[0079] Continue to refer Figure 7 A limit block 64 is fixedly installed at the bottom of the cover plate 51 to limit the moving distance of the slider 6, that is, when the slider 6 abuts against one side of the limit block 64, the disc 571 and the rotating disk 55 complete the clamping operation of the battery. At the same time, a driving gear 62 is sleeved on one end of the rotating cylinder 61, and the bottom of the limit block 64 and the bottom of the moving block 604 are both higher than the top of the driving gear 62, so that when the slider 6 abuts against one side of the limit block 64, the driving gear 62 can pass under the limit block 64, thereby avoiding mechanical interference;

[0080] At the same time, two groups of mounting blocks 66 are fixedly installed at the bottom of the top plate 510, and a round rod 67 is rotatably installed on the mounting block 66, and a driven gear 65 is fixedly sleeved on one end of the round rod 67 close to the limit block 64, and a sprocket 58 is fixedly sleeved on one end of the round rod 67 away from the limit block 64 and the other end of the rotating rod 57, and a chain 59 is transmitted on the two groups of sprockets 58;

[0081] So that under the action of external force, the driven gear 65 drives the round rod 67 to rotate, and then the rotating rod 57 and the disc 571 are driven to rotate through the cooperation of the chain 59 and the sprocket 58;

[0082] In summary, during the test, the battery to be tested is placed between the disc 571 and the rotating disc 55, and the servo motor 53 is started to drive the screw 63 to rotate. At this time, due to the restriction of the plug block 605, the rotating drum 61 drives the slider 6 and the moving block 604 to move on the slide rail 68 in the direction close to the second clamping plate 56, thereby driving the first clamping plate 54 and the rotating disc 55 to move in the direction of the second clamping plate 56 until the moving block 604 first contacts the limit block 64. At this time, since the plug block 605 and the rotating drum 61 have not yet separated, the slider 6 will continue to move, thereby driving the moving block 60 4 continues to move, and due to the restriction of the limit block 64, the moving block 604 will slide into the inside of the slide groove 603, driving the short rod 606 to move from the left end to the right end, and then driving the plug block 605 to move upward in the vertical groove 601. At this time, the spring 602 is compressed. When the short rod 606 moves to the right end, the slider 6 abuts against the limit block 64, and the driving gear 62 and the driven gear 65 are engaged. At the same time, the plug block 605 is separated from the slot of the rotating drum 61. At this time, the rotating drum 61 loses its restriction, and the battery to be tested is clamped by the rotating disk 55 and the disk 571.

[0083] When the angle of the battery needs to be adjusted, the servo motor 53 is continued to be started, thereby driving the screw 63 to rotate. At this time, since the insert block 605 of the rotating drum 61 is separated from the slot of the rotating drum 61, the rotating drum 61 can idle on the screw 63, thereby driving the driving gear 62 to rotate, and driving the round rod 67 to rotate through the driven gear 65, and then driving the rotating rod 57 and the disc 571 to rotate through the cooperation of the chain 59 and the sprocket 58, so as to drive the battery to rotate, thereby adjusting the angle of the battery, and then simulating the test of the battery at different angles;

[0084] It should be noted that a detection instrument is provided inside the turntable 55, and a test interface 511 is provided on the turntable 55, the test interface 511 is electrically connected to the detection instrument, and the detection instrument is connected to the PLC system, so as to connect the output end of the battery to the test interface 511, so as to upload and record the data change of the battery in real time when the angle of the battery changes during the test process, so as to facilitate the subsequent evaluation of the battery performance, and a temperature insulation cover (not shown in the figure) is provided outside the servo motor 53 to reduce the influence of high temperature and low temperature on it;

[0085] After the test is completed, when the battery needs to be removed, the staff holds the battery and rotates the servo motor 53 in the opposite direction to drive the screw 63 to rotate in the opposite direction, thereby driving the rotating drum 61 and the slider 6 to move in the opposite direction and separate from the limit block 64. At this time, under the action of the spring 602, the plug block 605 drives the short rod 606 to move from the right end to the left end of the inclined slot 607, thereby driving the moving block 604 to move to the right until the plug block 605 enters the slot of the rotating drum 61. At this time, the short rod 606 is located at the left end of the inclined slot 607, and the turntable 55 is away from the disc 571 to release the clamping of the battery.

[0086] Embodiment 3: Although the above process can achieve the angle adjustment of the battery, since the battery quickly enters the low temperature environment from the high temperature, the surface temperature of the battery drops rapidly, and the water vapor in the surrounding air is cooled, the water vapor will condense into small water droplets on the surface of the battery. If the water droplets penetrate into the battery, it will further disrupt the composition and distribution of the electrolyte.

[0087] In order to solve this problem, a transition component 7 is provided on the partition 26, and the transition component 7 is used for transition processing when the battery enters a low temperature environment from a high temperature, so as to prevent the battery from entering a low temperature environment quickly from a high temperature, so as to reduce the generation of water droplets;

[0088] like Figure 10-12 As shown, the transition assembly 7 includes a transition plate 71 fixedly mounted on the top of the partition 26, and in this embodiment, the housing 22 is mounted on the transition plate 71;

[0089] At the same time, an extension plate 74 is fixedly installed at the bottom of the partition plate 26, and a transition groove 72 with the same structure as the through groove 27 is provided on both the transition plate 71 and the extension plate 74. It should be noted that the transition groove 72 is connected to the through groove 27. For the convenience of description, the space formed by the two groups of transition grooves 72 and the through groove 27 is defined as a transition cavity. At the same time, an air intake grille 73 is provided on the inner wall of the transition groove 72 on the transition plate 71;

[0090] Continue to refer Fig.12 A blower 75 is fixedly installed inside the lower installation cavity 33, and a connecting pipe 76 is provided at the output end of the blower 75. The end of the connecting pipe 76 away from the blower 75 extends into the extension plate 74, the partition plate 26 and the transition plate 71 and is connected to the air intake grille 73. Then, driven by the blower 75, the air at room temperature inside the lower installation cavity 33 is sent into the connecting pipe 76 and sprayed out through the air intake grille 73, thereby cooling the battery entering the transition cavity and drying the water droplets generated on the surface of the battery during the cooling, so as to restore it to a normal temperature state;

[0091] At the same time, an exhaust pipe (not shown in the figure) is arranged on the inner wall of the transition groove 72 on the transition plate 71, one end of the exhaust pipe is arranged opposite to the air intake grille 73, and the other end of the exhaust pipe passes through the chassis 1, and a fan is arranged inside the exhaust pipe to facilitate the exhaust of the dried gas;

[0092] In summary, after the adjustment component 5 clamps and adjusts the angle of the battery, when the carrying component 4 transports the battery from a high temperature to a low temperature environment, when the cover plate 51 enters the transition chamber, the cover plate 51 seals the bottom of the transition chamber, and when the carrying plate 44 enters the transition chamber, the carrying plate 44 seals the top of the transition chamber. At this time, the battery between the cover plate 51 and the carrying plate 44 is in a relatively closed space. The PLC system can control the driving device of the carrying component 4 to rotate slowly to extend the process of sending the battery into the low temperature, start the blower 75 to supply air, and pass the air at normal temperature through the air intake grille 73. At the same time, the angle adjustment component 5 can rotate the battery a certain number of times, so that the wind ejected by the blower 75 through the air intake grille 73 can be fully blown to the outer surface of the battery, so as to cool the high-temperature battery and restore it to a normal temperature state. At the same time, the moisture generated by condensation on the battery surface when the high temperature changes to the low temperature can be fully dried, and the dried gas can be discharged through the exhaust pipe to realize the battery to return to normal temperature and dry it before entering the refrigeration cabinet 32, so as to avoid the high-temperature battery quickly entering the low-temperature environment. A large number of water droplets are generated on the surface of the battery due to condensation, which affects the battery;

[0093] It should be noted that when the battery is subjected to high and low temperature tests, the battery can also be tested from low temperature to high temperature first, such as clamping the battery through the adjustment component 5 and connecting it to the test instrument through the test interface 511, and then sending it to the refrigeration component 3 through the carrier component 4 to stand for a period of time for low temperature testing. At the same time, the adjustment component 5 can continue to be started to adjust its angle during the standing process. After the low temperature test is completed, the carrier component 4 sends the battery to the transition component 7, and the transition component 7 restores the low-temperature battery to normal temperature and then sends it to the heating component 2 for high temperature testing. When the battery returns to normal temperature, the gas generated by evaporation is discharged through the exhaust pipe to avoid excessive water droplets accumulating at the bottom of the carrier plate 44 and dripping on the battery surface;

[0094] The present application also provides a detection method for a high and low temperature detection device for a drone battery, which specifically comprises the following steps:

[0095] Step 1: The refrigeration component 3 is normally open, the box door is opened, the battery is placed in the adjustment component 5 for clamping, the battery output end is connected to the test interface 511 of the detection instrument, and the box door is closed;

[0096] Step 2: Start the heating component 2 to heat the outside of the battery, start the adjustment component 5 to adjust the battery angle, and wait for a period of time. At the same time, the detection instrument uploads and records the data changes of the battery;

[0097] Step 3, start the carrier assembly 4, send the battery into the refrigeration assembly 3, and run it slowly at the transition assembly 7, start the heat dissipation fan 102 and the air outlet pipe 101 to dissipate heat from the heating assembly 2;

[0098] Step 4: the transition component 7 is started, and the regulating component 5 drives the battery to rotate a certain number of times to fully dry the battery and restore it to normal temperature, while discharging the dried gas;

[0099] Step 5: The load-bearing component 4 puts the room temperature battery into the refrigeration component 3 and waits for a period of time, while the detection instrument uploads and records the data changes of the battery;

[0100] Step 6: The carrier assembly 4 returns the battery to the heating assembly 2 and runs slowly at the transition assembly 7. The transition assembly 7 starts to restore the battery to normal temperature and discharge the evaporated gas at the same time;

[0101] Step seven, the carrier component 4 delivers the battery into the heating component 2, starts the cooling fan 102 and the air outlet pipe 101 to dissipate heat, then opens the box door, starts the adjustment component 5 to release the clamping, and takes out the battery.

For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
