Description

Technical Field

[0001] The present invention relates to the technical field of electric energy storage devices, and particularly relates to an inner liner of a modular drone battery charging cabinet. Background Art

[0002] Currently, drone technology has been widely applied in multiple fields. In agriculture, it can be used for pesticide spraying and crop monitoring. In the logistics industry, it can achieve rapid delivery services. In terms of public safety, drones are involved in search and rescue, firefighting, and security patrols. In addition, drones also play an important role in environmental monitoring, infrastructure inspection, etc., greatly improving work efficiency and safety.

[0003] During use, drones need to frequently replace batteries and charge them. At present, the most convenient method is to use a dedicated drone battery charging cabinet, which can ensure that the batteries are quickly fully charged and is convenient for management and storage.

[0004] In the prior art, most patents are provided with sockets in the charging cabinet. When charging, it is necessary to insert and unplug the charging lines in the narrow space of the charging cabinet, which is not convenient and has potential safety hazards.

[0005] The patent with the publication number CN208835814U relates to a plug-and-play lithium battery charging cabinet. Charging output sockets are fixedly arranged on the front surfaces of the socket fixing plates; the input ends of the charging output sockets are all connected to the output ends of the battery charging modules; batteries are arranged on the battery support frames; socket holes matching the charging output sockets are arranged on the batteries; and a battery guiding device for inserting the socket holes into the charging output sockets in a directional manner is arranged on the battery support frames.

[0006] The following problems exist during use: the charging output sockets, the socket holes on the batteries, and the battery support frames are all fixed components, and their positions, shapes, sizes, and other parameters cannot be adjusted quickly and conveniently. In practice, for drones of different brands and models, the sizes, shapes, charging port positions, charging port forms, etc. of the batteries are all different, which results in the fact that this patent cannot meet the charging requirements of various drone batteries; in addition, there are no fire protection measures. Especially for electrical equipment such as drone batteries that have the risk of spontaneous combustion and explosion, special fire protection facilities are required.

[0007] In view of this, research and improvement are carried out on the existing structures and deficiencies, and an inner liner of a modular drone battery charging cabinet is provided to achieve the purpose of enhancing practical value. Summary of the Invention

[0008] Aiming at the deficiencies of the prior art, the present invention provides an inner liner of a modular drone battery charging cabinet, which can quickly and conveniently adjust parameters such as position, shape, and size to meet the rapid charging use of drone batteries of different brands and models.

[0009] The present invention is realized through the following technical solutions: Provide a modular inner liner for a drone battery charging cabinet, including a main frame. The front and back of the main frame are both open. A slide rail adjustment component is installed at the back of the main frame, and a battery plug-in component is installed in the inner cavity of the main frame. The slide rail adjustment component includes two vertically arranged first slide rails and a second slide rail vertically connected between the two first slide rails. The two first slide rails are respectively fixed on the folded edges formed by the vertical edges of the two side plates at the back of the main frame. A first slider is slidably connected to each first slide rail. The plane of the first slider away from the first slide rail is threadedly connected with a locking knob. The screw rod of the locking knob penetrates through the first slider and can abut against the first slide rail. Both ends of the second slide rail are connected to the corresponding first slider through a plug and a bolt. A second slider is slidably connected to the second slide rail. The top of the second slider is threadedly connected with a locking bolt near the edge position. The locking bolt penetrates through the second slider and can abut against the second slide rail. The battery plug-in component includes a charging base installed on the second slider and a plug-in sleeve installed on the inner bottom surface of the main frame and open at the front and back. The surface of the charging base facing the plug-in sleeve is provided with a docking cavity for docking the drone battery. A battery charging interface is arranged in the docking cavity. A charger interface is arranged at the top of the charging base, and the charger is plugged into the socket in the charging cabinet. A plurality of pressing blocks capable of limiting the battery are movably installed on the inner top wall and one inner side wall of the plug-in sleeve.

[0010] Through the slide rail adjustment component in this solution, two-dimensional adjustment of the charging base can be realized, which can conveniently adjust the position of the charging base to adapt to the charging of the drone motor at different charging positions. At the same time, by using the design of the pressing blocks on the inner wall of the battery plug-in component, after the drone battery is inserted into the plug-in sleeve, the pressing blocks can tighten inward to adapt to the shapes and sizes of different drone batteries.

[0011] Further, a positioning groove is vertically opened in the middle of the surface of the second slider facing the charging base. The upper end of the positioning groove is open and the lower end is closed. A positioning slider that can be slidably matched with the positioning groove is vertically arranged at the back of the charging base.

[0012] A positioning groove is opened on the second slider. The upper part of the positioning groove is open and the lower part is closed, which is used for plugging and matching with the positioning slider at the back of the charging base, facilitating disassembly and installation.

[0013] Further, the length of the plug is longer than the width of the second slide rail. Second counterbores are respectively opened at both ends of the plug on the extension line of the width of the second slide rail, and a third counterbore facing the end face of the second slide rail is opened between the two second counterbores. The directions of the second counterbore and the third counterbore are opposite. The plug is fixed to both ends of the second slide rail through the third counterbore and fixed to the side surface of the first slider through the second counterbore.

[0014] The plug and the second countersunk hole and the third countersunk hole formed on the plug cooperate with bolts to connect and fix the second slide rail and the first slide block, so as to facilitate two-dimensional adjustment of the position of the charging seat.

[0015] Furthermore, the inner wall of the plug-in sleeve is recessed to form a groove for installing a clamping block. The clamping block is wing-shaped, with a raised portion on one side and a straight portion on the other side. The straight portion faces the groove, and one end of the straight portion is rotatably connected to one end of the groove via a rotating shaft. A first spring is connected between the other end of the straight portion and the inner wall of the groove.

[0016] Through the movably arranged clamping block, after the drone battery is inserted into the plug sleeve, the clamping block is squeezed by external force, swings a few angles toward the inner wall of the plug sleeve, and shrinks into the plug sleeve. At this time, the clamping block cooperates with the bottom and the other side wall of the plug sleeve to fix the drone battery around. The wing-shaped structure of the clamping block makes it easier to insert the drone battery into the plug sleeve. However, when the drone battery has a tendency to move out of the plug sleeve in the opposite direction, a certain resistance will be generated to prevent the drone battery from being disconnected from the battery charging interface, thereby ensuring the reliable connection of the charging interface when the drone battery is charging.

[0017] Furthermore, the straight portion is provided with a limiting portion extending from one end of the first spring, and the end surface of the groove is convexly provided with a fixing portion which can abut against the limiting portion and prevent the limiting portion from escaping from the groove.

[0018] The limiting portion provided on the straight portion can cooperate with the fixing portion of the end face of the groove to limit the rotation of the pressing block so that it can be limited to rotate in the groove to ensure the clamping and positioning effect of the drone battery.

[0019] Furthermore, a sliding groove is recessed in the middle of the bottom surface of the plug-in sleeve along the depth direction of the main frame, and a sliding rail that slides with the sliding groove is installed on the inner bottom surface of the main frame. A mounting groove that is vertically connected to the sliding groove is opened on one side of the sliding groove at the front bottom of the plug-in sleeve, and a toggle groove that is connected to the mounting groove is opened in front of the plug-in sleeve. A stop pin is provided in the mounting groove, and the side surface of the stop pin is connected to a toggle column located in the toggle groove. The tail of the stop pin and the end of the mounting groove are connected to a second spring, and the head of the stop pin can abut against the sliding rail to limit the plug-in sleeve.

[0020] By opening an installation groove in the front bottom of the plug-in sleeve, the stop pin head in the installation groove can be used to cooperate with the second spring to abut against the slide rail. The stop pin head can be controlled to abut against different positions of the slide rail by toggling the toggle column, so as to facilitate the adjustment of the position of the plug-in sleeve on the slide rail, so that the plug-in sleeve and the charging seat maintain a suitable distance, which is convenient for the insertion and charging of the drone motor.

[0021] Furthermore, the cross-section of the slide rail is T-shaped. On one side of the upper horizontal part of the slide rail facing the stop pin, stop grooves for plugging and mating with the head of the stop pin are evenly opened along the length direction. A number of first counterbores are evenly opened on the length axis of the upper horizontal part of the slide rail. In the middle of the inner bottom surface of the main frame, a row of central threaded holes corresponding to the first counterbores one by one are opened. The slide rail and the inner bottom surface of the main frame are connected by bolts in the first counterbores and the threaded holes.

[0022] The first counterbores are opened on the upper horizontal part of the slide rail, which can cooperate with bolts to fixedly install the slide rail on the central threaded holes of the inner bottom surface of the main frame. The upper horizontal part of the slide rail is used for sliding cooperation with the plugging sleeve, and can also be in abutting cooperation with the stop pin in the stop groove, so as to position the plugging sleeve.

[0023] Preferably, on both sides of a row of central threaded holes on the inner bottom surface of the main frame, two rows of side threaded holes symmetrically arranged are respectively opened.

[0024] By providing two rows of threaded holes, they can be respectively used to connect the slide rails. When the volume of the drone battery to be charged is small, the charging work of two drone batteries can also be completed simultaneously in the same inner container. At this time, a row of central threaded holes at the midline position of the inner bottom surface of the main frame is not installed with a slide rail. Two slide rails are respectively installed on two rows of side threaded holes that are symmetrically arranged left and right, and a plugging sleeve is installed on each of the two slide rails. At the same time, two second sliders are also installed on the second slide rail, and a charging seat is inserted on each second slider, so as to form two sets of battery plugging components. After adjusting the positions of the respective battery plugging components, the charging work can be started simultaneously.

[0025] Further, a thermo-aerosol fire extinguishing device is installed at the top of the inner cavity of the main frame. A heat-sensitive wire is arranged on one side of the thermo-aerosol fire extinguishing device, and the heat-sensitive wire extends to one side inside the main frame.

[0026] The thermo-aerosol fire extinguishing device cooperates with the heat-sensitive wire. When the drone battery catches fire spontaneously, the thermo-aerosol fire extinguishing device can quickly spray aerosol fire extinguishing agent, so as to isolate the air and quickly reduce the temperature, ensuring the safety of the drone battery charging.

[0027] Further, the main frame is a cuboid cavity structure without covers at the front and back, and is surrounded by bolted and movable connections of a top plate, a bottom plate and two side plates.

[0028] The main frame is an open cuboid cavity structure without covers at the front and back, and is formed by splicing and surrounding the top plate, the bottom plate and the two side plates, which is convenient for assembly and use.

[0029] Preferably, a weight-reducing hole is respectively opened on each side plate.

[0030] Weight-reducing holes are opened on each side plate of the main frame. On the one hand, it can reduce the weight and save costs. On the other hand, the weight-reducing holes can be used to improve the internal air flow and facilitate faster heat dissipation.

[0031] Furthermore, two screws penetrating through each side plate are threadedly connected to the upper part of each side plate. One end of each screw outside the side plate is rotatably connected to a fixed suction cup, and a polygonal blind hole adapted to cooperate with a wrench is formed on the end face of the other end of each screw inside the side plate.

[0032] By inserting the wrench into the polygonal blind hole to rotate the screw, the fixed suction cup at the end of the screw can be driven to extend or retract, so that the main frame can adapt to charging cabinets of different sizes. After the inner container is placed in the charging cabinet, the screw is rotated according to the size of the charging cabinet to adjust its extending length, so that each fixed suction cup tightly presses and adsorbs on the inner walls on both sides of the charging cabinet, ensuring that the inner container is firmly installed in the charging cabinet and ensuring the stability of charging.

[0033] Preferably, strip-shaped heat dissipation holes are uniformly formed on the inner wall of the other side of the insertion sleeve where no pressing block is provided.

[0034] Strip-shaped heat dissipation holes are uniformly formed on the side wall of the insertion sleeve where no pressing block is provided, which can dissipate heat during the charging of the UAV battery. Moreover, when the UAV battery catches fire, it is convenient for the aerosol fire extinguishing agent to quickly surround the outer shell of the UAV battery, ensuring the fire extinguishing effect.

[0035] The beneficial effects of the present invention: The modular inner container of the UAV battery charging cabinet of the present invention adopts a modular design. A plurality of pressing blocks are arranged on the inner wall of the insertion sleeve. After the UAV battery is inserted into the insertion sleeve, the pressing blocks can tighten inward to adapt to the shapes and sizes of different UAV batteries. At the same time, the pressing blocks can clamp and position the UAV motor, ensuring the charging stability.

[0036] The charging seat can be processed by 3D printing. The charging seat form matching the corresponding UAV battery can be quickly manufactured according to the actual situation, forming a modular and serialized inner container design. Moreover, the charging seat and the second slider are in quick-insert connection, which is convenient for quick disassembly and replacement. In addition, the slide rail adjustment assembly can also conveniently adjust the position of the charging seat, enabling it to be arbitrarily adjusted in the two-dimensional plane, so that the charging seat can better dock and insert the UAV battery inserted into the insertion sleeve, thereby meeting the charging requirements of different UAV motors.

[0037] A hot aerosol fire extinguishing device is configured in the main frame, which can use the thermal sensitive wire to monitor the temperature in the warehouse. When a battery catches fire, hot melt adhesive can be sprayed in time for air isolation to achieve efficient fire extinguishing and ensure charging safety. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0049] To clearly illustrate the technical features of this solution, the following elaborates on this solution through specific implementation manners.

[0050] Such as Figures 1 - 8As shown in the figure, a modular inner liner of a drone battery charging cabinet includes a main frame 1. The front and rear of the main frame 1 are both open. The main frame 1 is a cuboid cavity structure without covers at the front and rear, and is enclosed by bolted and movable connections of a top plate 11, a bottom plate 12 and two side plates 13. At the upper part of each side plate 13, two screw rods 132 penetrating the side plate are threadedly connected. One end of the screw rod 132 outside the side plate 13 is rotatably connected with a fixed suction cup 131, and a polygonal blind hole 133 that can cooperate with a wrench is opened at the end surface of one end of the screw rod 132 inside the side plate 13. Weight-reducing holes are respectively opened on each side plate 13. In this embodiment, the end of the screw rod 132 is a regular hexagonal blind hole, which can cooperate with an inner hexagon wrench. Under the action of the inner hexagon wrench, the screw rod 132 rotates. When the screw rod 132 rotates clockwise, the screw rod 132 extends linearly outward relative to the main frame 1. When it rotates counterclockwise, the screw rod 132 contracts inward relative to the main frame 1, thereby driving the fixed suction cup 131 to reciprocate linearly in a direction perpendicular to the side plate 13, so that the main frame 1 can adapt to charging cabinets of different sizes. After the inner liner is placed in the charging cabinet, rotate the screw rod 132 according to the size of the charging cabinet to adjust its extension length, so that each fixed suction cup 131 tightly presses and adsorbs on the inner walls on both sides of the charging cabinet, ensuring that the inner liner is firmly installed in the charging cabinet.

[0051] A heat aerosol fire extinguishing device 111 is installed at the top of the inner cavity of the main frame 1. A thermal sensitive wire 112 is provided on one side of the heat aerosol fire extinguishing device 111, and the thermal sensitive wire 112 extends to one side inside the main frame 1. When a drone battery catches fire spontaneously, the heat aerosol fire extinguishing device 111 can quickly spray out aerosol fire extinguishing agent to achieve the effect of isolating air and quickly reducing the temperature.

[0052] A slide rail adjusting component 2 is installed at the back of the main frame 1, and a battery plugging component 3 is installed in the inner cavity of the main frame 1.

[0053] The slide rail adjusting component 2 includes two vertically arranged first slide rails 21 and a second slide rail 23 vertically connected between the two first slide rails 21. The two first slide rails 21 are respectively fixed on the folded edges 134 formed by bending the vertical edges of the two side plates 13 at the back of the main frame 1. A first slider 22 is slidably connected to each first slide rail 21. A locking knob 221 is threadedly connected to the plane of the first slider 22 away from the first slide rail 21. The screw rod of the locking knob 221 penetrates the first slider 22 and can abut against the first slide rail 21.

[0054] The locking knob 221 penetrates the first slider 22 and can contact the first slide rail 21. When the first slider 22 is moved to the target position on the first slide rail 21, rotating the locking knob 221 clockwise can make it press tightly on the first slide rail 21, thereby realizing the locking of the first slider 22 on the first slide rail 21. When it is necessary to move the first slider 22 again, just rotate the locking knob 221 counterclockwise to loosen the first slide rail 21.

[0055] Both ends of the second slide rail 23 are connected to the corresponding first slider 22 through plugs 25 and bolts. A second slider 24 is slidably connected to the second slide rail 23. A locking bolt 242 is threadedly connected to a position near the edge at the top of the second slider 24. The locking bolt 242 penetrates through the second slider 24 and can abut against the second slide rail 23.

[0056] In this embodiment, the second slider 24 is slidably connected to the second slide rail 23 and can perform horizontal reciprocating linear motion along the second slide rail 23. Through the cooperation of the first slide rail 21 and the first slider 22 and the cooperation of the second slide rail 23 and the second slider 24, the second slider 24 can be arbitrarily adjusted in position within a two-dimensional plane in the horizontal and vertical directions, that is, within the main frame 1. A locking bolt 242 is screwed near the edge in the middle of the top of the second slider 24. The locking bolt 242 penetrates through the second slider 24 and can contact the second slide rail 23. By screwing the locking bolt 242 to press it against the second slide rail 23, the locking of the second slider 24 on the second slide rail 23 can be completed.

[0057] The battery plugging assembly 3 includes a charging base 32 installed on the second slider 24 and a plugging sleeve 31 installed on the inner bottom surface of the main frame 1 and open at the front and rear. On one side of the charging base 32 facing the plugging sleeve 31, a docking cavity 311 for docking the UAV battery is provided. A battery charging interface 312 is provided in the docking cavity 311. A charger interface 313 is provided at the top of the charging base 32, and the charger is plugged into the socket in the charging cabinet; A plurality of pressing blocks 321 capable of limiting the battery are movably installed on the inner top wall and one inner wall of the plugging sleeve 31. Strip-shaped heat dissipation holes 324 are evenly provided on the other inner wall of the plugging sleeve 31 where the pressing blocks 321 are not provided.

[0058] A positioning groove 241 is vertically opened in the middle of the side of the second slider 24 facing the charging base 32. The upper end of the positioning groove 241 is open and the lower end is closed; A positioning slider 314 that can be slidably matched with the positioning groove 241 is vertically provided on the back of the charging base 32. The positioning slider 314 can cooperate with the positioning groove 241 to enable the charging base 32 to be quickly disassembled and assembled on the second slider 24. The charging base 32 is provided with a docking cavity 311 for docking the bottom of the UAV battery. A battery charging interface 312 is provided in the docking cavity 311. After the UAV battery is inserted into the battery plugging assembly 3, the battery charging interface 312 can be directly docked with the corresponding charging port of the UAV battery, which is convenient, fast, safe and reliable. A charger interface 313 is provided at the top of the charging base 32. When the charging base 32 is inserted into the second slider 24, the charger of the charging base 32 is inserted into the socket in the charging cabinet to make the charging base 32 powered on and work. The charging base 32 is processed by 3D and can quickly manufacture a matching structure according to different brands and models of UAV batteries. When it is necessary to charge a certain specific model of UAV battery, only need to quickly replace the corresponding charging base 32.

[0059] The length of the plug 25 is longer than the width of the second slide rail 23. Second countersunk holes 251 are respectively provided at both ends of the plug 25 on the extension line of the width of the second slide rail 23, and a third countersunk hole 252 is provided between the two second countersunk holes 251 to face the end face of the second slide rail 23. The second countersunk holes 251 and the third countersunk holes 252 are in opposite directions. Bolts fix the plug 25 to the two ends of the second slide rail 23 through the third countersunk holes 252, and fix the plug 25 to the side of the first slider 22 through the second countersunk holes 251.

[0060] The inner wall of the plug-in sleeve 31 is recessed to form a groove for installing a clamping block 321. The clamping block 321 is wing-shaped, with a raised portion on one side and a straight portion on the other side. The straight portion faces the groove, and one end of the straight portion is rotatably connected to one end of the groove through a rotating shaft 323. A first spring 322 is connected between the other end of the straight portion and the inner wall of the groove.

[0061] The straight portion is provided with a limiting portion extending from one end of the first spring 322 , and the end surface of the groove is convexly provided with a fixing portion which can abut against the limiting portion and prevent the limiting portion from escaping from the groove.

[0062] A slide groove 325 is recessed in the middle of the bottom surface of the plug-in sleeve 31 along the depth direction of the main frame 1, and a slide rail 121 slidably matched with the slide groove 325 is installed on the inner bottom surface of the main frame 1. A mounting groove vertically connected to the slide groove 325 is opened on one side of the slide groove 325 at the front bottom of the plug-in sleeve 31, and a toggle groove connected to the mounting groove is opened in front of the plug-in sleeve 31. A stop pin 326 is provided in the mounting groove, and the side of the stop pin 326 is connected to a toggle column 327 located in the toggle groove. The tail of the stop pin 326 is connected to the end of the mounting groove with a second spring 328, and the head of the stop pin 326 can abut against the slide rail 121 to limit the plug-in sleeve 31.

[0063] The wing-shaped structure of the clamping block 321 makes it easier to insert the drone battery into the plug sleeve 31, but when the drone battery has a tendency to move out of the plug sleeve 31 in the opposite direction, a certain resistance will be generated to prevent the drone battery from being disconnected from the battery charging interface 312, thereby ensuring the reliable connection of the charging interface when the drone battery is charged. A strip heat dissipation hole 324 is provided on the side of the plug sleeve where the clamping block 321 is not installed. The strip heat dissipation hole 324 can be used for heat dissipation when the drone battery is charging, and when the drone battery spontaneously combusts, it can also facilitate the aerosol fire extinguishing agent to quickly surround the drone battery shell.

[0064] The bottom of the socket 31 is provided with a sliding groove 325 which can cooperate with the sliding rail 121 to enable the socket 31 to be slidably connected to the bottom plate 12. At the lower part of the socket 31 on one side of the sliding groove 325, a stop pin 326 is provided. A toggle column 327 is connected to the side of the stop pin 326 and a second spring 328 is provided at the tail. When there is no external force, under the action of the second spring 328, the stop pin 326 is inserted into the sliding rail 121 to relatively fix the socket 31 and the bottom plate 12. In this embodiment, in order to facilitate the insertion and cooperation of the sliding rail 121 and the stop pin 326, the sliding rail 121 is evenly provided with slots along the length direction, as Figure 7 shown. When it is necessary to adjust the position of the socket 31 on the bottom plate 12 according to the length of the UAV battery, it is necessary to pull the toggle column 327 to move the head of the stop pin 326 out of the sliding groove 325, and then the position of the socket 31 can be adjusted axially along the sliding rail 121.

[0065] The cross section of the sliding rail 121 is in a T shape. On the side of the upper horizontal part of the sliding rail 121 facing the stop pin 326, stop grooves which are inserted and matched with the head of the stop pin 326 are evenly provided along the length direction. On the length axis of the upper horizontal part of the sliding rail 121, a number of first counterbores 122 are evenly provided. In the middle of the inner bottom surface of the main frame 1, a row of central threaded holes corresponding to the first counterbores 122 one by one are provided. The sliding rail 121 and the inner bottom surface of the main frame 1 are connected by bolts in the first counterbores 122 and the central threaded holes.

[0066] On both sides of a row of central threaded holes on the inner bottom surface of the main frame 1, two rows of symmetrically arranged side threaded holes 123 are respectively provided.

[0067] In this embodiment, the bottom plate 12 is provided with a number of threaded holes. The threaded holes are linearly distributed in three rows. The middle row is the central threaded hole, which is located at the middle line position of the bottom plate 12. The other two rows are symmetrically distributed on both sides of the middle line of the bottom plate 12 and are the side threaded holes 123. The sliding rail 121 is provided with a number of first counterbores 122. The first counterbores 122 are linearly distributed along the axial direction of the sliding rail 121 and correspond to the positions of the central threaded holes, so that the sliding rail 121 can be movably installed on the bottom plate 12 through bolts. If adjustment is needed during actual work, by cooperating the sliding rail 121 with different rows of central threaded holes or side threaded holes 123, the position of the sliding rail 121 on the bottom plate 12 can be changed.

[0068] When the drone battery of the present invention is charged for the first time, according to the model of the drone battery to be charged, the corresponding charging base 32 is inserted on the second slider 24, and its position is adjusted according to the size and structure of the charging base 32. After aligning the charging base 32 with the socket sleeve 31, the first slider 22 and the second slider 24 are locked. Subsequently, the position of the socket sleeve 31 on the bottom plate 12 is adjusted to keep a proper distance between the socket sleeve 31 and the charging base 32. After the above operations are completed, the drone battery is inserted into the inner container. The socket sleeve 31 fixedly supports the outer shell of the drone battery, and the charging base 32 docks with the bottom of the drone battery to achieve docking charging. After charging is completed, the drone battery is directly pulled out. For subsequent charging, the drone battery can be directly inserted and pulled out until it is necessary to charge the drone battery of other models and then readjust.

[0069] When the volume of the drone battery to be charged is small, the charging of two drone batteries can also be completed simultaneously in the same inner container. At this time, a row of central threaded holes at the midline position of the bottom plate 12 does not install the slide rail 121. Two slide rails 121 are respectively installed on two rows of side threaded holes 123 symmetrically arranged on the left and right of the bottom plate 12, and a socket sleeve 31 is installed on each of the two slide rails 121. At the same time, two second sliders 24 are also installed on the second slide rail 23, and a charging base 32 is inserted on each second slider 24, thus forming two sets of battery socket assemblies 3. After adjusting the positions of the respective battery socket assemblies 3, the charging work can be started simultaneously.
