[0002] Drone technology has developed rapidly in recent years and has become an indispensable high-tech tool in many fields. Drones play an important role in agricultural plant protection, equipment maintenance, disaster relief, environmental monitoring and other fields. Batteries are the energy source of drones. Drones consume a lot of power when working, so batteries need to be replaced and charged frequently when using drones. The fastest and most efficient way is to use a dedicated drone battery charging cabinet.

[0003] In the prior art, the patent with application number 202122781868.8 provides a drone battery charging cabinet, including a charging cabinet, the charging cabinet is provided with a first cabinet door and a second cabinet door through a hinge, and a door lock mechanism is provided on the first cabinet door and the second cabinet door; a plurality of detachable partitions are provided in the charging cabinet, and a drone battery placement area is formed between adjacent partitions, and a charging interface is provided in the drone battery placement area; a plurality of cooling fans are provided on the outer shell of the charging cabinet, and a vent is provided on the top of the charging cabinet; an intelligent protector is provided on the outside of the charging cabinet, and one end of the intelligent protector is connected to the main power cord, and the other end is connected to the charging interface. The detachable multi-partition design in the patent can adaptively set the size of the drone battery placement area to adapt to the placement and charging of drone batteries of different sizes, thereby improving space utilization. At the same time, the charging interface designed for each battery placement area ensures that the charging harness will not be crossed and messy, and unified charging management can be achieved.

[0004] But there are still the following problems:

[0005] In order to adapt to drone batteries of different sizes, it is necessary to disassemble and adjust the spacing between partitions, which is a complicated operation and not conducive to the installation and fixation of fire-fighting equipment. For the battery placement area above or below the charging cabinet, the operator needs to tiptoe, bend over or squat to plug and unplug the charging line in a small space during charging, which is inconvenient to operate and easily creates safety hazards.

[0006] In view of this, the existing UAV charging cabinet structure is studied and improved, and a UAV battery charging cabinet liner that is suitable for multiple devices is provided, in order to achieve a purpose with greater practical value. Summary of the invention

[0007] The present invention provides an inner tank of a battery charging cabinet for a drone that is adaptable to multiple devices, so as to solve the problem that the operation of existing charging cabinets is relatively complicated. When charging in an upper or lower battery placement area, an operator needs to stand on tiptoe, bend over or squat to plug or unplug the charging line in a narrow space, which is inconvenient to operate and easily causes safety hazards.

[0008] The present invention is achieved through the following technical solutions:

[0009] Provided is an inner liner of a drone battery charging cabinet that is adaptable to multiple devices, comprising an inner liner frame and a battery box that is detachably plugged into the inner liner frame;

[0010] The inner shell frame is a rectangular cavity structure with one side open, including a rear cover, side panels, top panel and bottom panel.

[0011] The battery box includes a box body and a box cover hinged to the box body by a hinge. A positioning groove is concavely arranged on the outside of the box body on one side facing the rear cover and facing the positioning boss. A charging concave interface that can be docked with the charging convex interface is arranged in the positioning groove. A charging socket is installed inside the side of the box body facing the rear cover, and the charging socket is electrically connected to the charging concave interface. At least one row of limit rings is arranged on the inner surface of the upper part of the box cover along the width direction of the box cover, and an elastic fixing component is vertically slidably connected in each limit ring. The elastic fixing component includes a bolt, a limit plate, a spring and a resist column. The length of the resist column is greater than the depth of the box cover cavity, and the lower end of the resist column is connected to a square plate. The upper end of the resist column passes through the box cover through the limit ring and is connected to the limit plate by a bolt on the upper outer surface of the box cover. The spring is sleeved on the resist column between the square plate and the limit ring. The square plates at the lower ends of the elastic fixing components in each row of limit rings are connected as a whole by a flexible fixing belt.

[0012] Furthermore, the two side panels of the inner liner frame are hollow in design and symmetrically distributed on both sides of the back cover. A number of top plate heat dissipation grooves are opened on the top plate. The inner wall of the top plate is also connected to a hot aerosol fire extinguishing device, and the thermistor line of the hot aerosol fire extinguishing device hangs on one side of the battery box.

[0013] The hollow design of the inner liner frame is used to accommodate the battery box. The top plate heat dissipation groove can be used to dissipate the heat generated by charging. At the same time, a hot aerosol fire extinguishing device is configured, which can be fixed by gluing or threading. The thermistor is used to detect the status of the battery below. When the drone battery spontaneously ignites in the charging cabinet, the thermistor will sense it and activate the hot aerosol fire extinguishing device to spray aerosol fire extinguishing agent, quickly isolate the air and quickly cool down, and kill the fire in the early stage.

[0014] Furthermore, two sliding bars with L-shaped cross-sections are symmetrically arranged on both sides of the width center line of the bottom plate of the inner liner frame, and a slideway is formed between the two sliding bars and the bottom plate; the box cover and the box body are both provided with sliding blocks with L-shaped cross-sections on the outer wall of one side where the two are hinged, and the two sliding blocks are arranged in parallel and slide in conjunction with the slideway.

[0015] A slide bar is arranged on the bottom plate of the inner shell frame to form a slideway, a slider is arranged on the box cover and the box body, and the battery box is slidably plugged into the slideway on the bottom surface of the inner shell frame through the slider, so that the battery box can be conveniently positioned and installed.

[0016] Furthermore, a plurality of heat dissipation grooves are provided at intervals on the top surface of the box cover, two hooks are installed near the lower edge on the outside of the switch surface of the box cover facing the hinge, and a buckle cooperating with the hooks is installed near the upper edge on the outside of the side surface of the box body located directly below the switch surface of the box cover.

[0017] A heat dissipation slot is provided on the top surface of the box cover for heat dissipation during battery charging. The box cover and the box body cooperate with each other at the opening surface through hooks and buckles, so that the box cover and the box body can be locked to ensure stability.

[0018] Furthermore, a handle is installed on one side of the box body in the width direction, a mounting groove is opened at one end of the front side of the handle and a locking block is movably installed in the mounting groove through an elastic mechanism, a clamping block which can extend out of the mounting groove is connected to the locking block, and a block is provided at the edge of the bottom plate of the inner liner frame at the open end, which is located between the two slide bars and is engaged with the clamping block, the height of the block is lower than the height of the slider on the box body, and the length of the block is smaller than the width of the slideway on the bottom plate.

[0019] A handle is installed on one side of the box body, and the handle is connected to a locking block by opening an installation groove and cooperating with an elastic mechanism. A card block is fixed on the exposed edge of one side of the locking block, and the card block is used to cooperate with the stopper to realize the locking and fixation of the battery box after it is inserted into the inner liner frame. An elastic mechanism is provided inside the locking block, and the locking block can slide inside the handle. Under the action of the elastic force of the elastic mechanism, the locking block is at the edge of the handle when there is no external force, so that the card block is exposed outside the handle. When the battery box needs to be removed, the locking block only needs to be slid toward the inside of the handle to shrink the card block into the handle, and the battery box can be taken out.

[0020] Furthermore, a plurality of box body heat dissipation grooves facing the box cover heat dissipation grooves are spaced apart on the inner bottom surface of the box body, and support edges facing and cooperating with the elastic fixing assembly are protruded between adjacent box body heat dissipation grooves.

[0021] The cross-section of the supporting edge is trapezoidal, and its position corresponds to the elastic fixing component in sequence. It is used to cooperate with the elastic fixing component to press the drone battery to ensure the reliable fixation of the drone battery.

[0022] Furthermore, a cooling fan is installed at the upper edge of the rear cover.

[0023] The cooling fan can be connected to the ventilation system of the drone battery charging cabinet, or can be directly connected to the external environment according to the design of the drone battery charging cabinet. The cooling fan can speed up the air flow inside the inner liner frame, thereby speeding up the heat dissipation.

[0024] Beneficial effects of the present invention:

[0025] 1. An elastic fixing component is arranged in the battery box of the present invention to cooperate with an elastic fixing strip.

DETAILED DESCRIPTION

[0038] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0039] like Figure 1 As shown, an inner liner of a drone battery charging cabinet that is suitable for multiple devices includes an inner liner frame 100 and a battery box 200 that can be detachably inserted into the inner liner frame 100; the inner liner frame 100 can be installed in the drone battery charging cabinet, and the battery box 200 is inserted into the inner liner frame 100, which is used for placing and fixing drone batteries of different brands and sizes.

[0040] like Figure 2 As shown, the inner liner frame 100 is a rectangular cavity structure with one side open, including a rear cover 110, a side panel 120, a top panel 130 and a bottom panel 140. The connection method can be welding or bolt connection. According to different drone charging cabinets, the size of the inner liner frame 200 can be adjusted and changed. A cooling fan 111 is installed at the edge of the upper part of the rear cover 110. The cooling fan 111 can be connected to the ventilation system of the drone battery charging cabinet, and can also be directly connected to the external environment according to the design of the drone battery charging cabinet. A positioning boss 112 is provided at the center of the lower edge of the rear cover 110, and a charging convex interface 113 connected to the main power supply of the drone charging cabinet is provided on the positioning boss 112.

[0041] The two side panels 120 of the liner frame 100 are hollow and symmetrically distributed on both sides of the rear cover 110. The top plate 130 is provided with a plurality of top plate heat dissipation slots 131 for discharging rising hot air. The inner wall of the top plate 130 is also connected to a hot aerosol fire extinguishing device 132, and the thermistor line 133 of the hot aerosol fire extinguishing device 132 is hung on one side of the battery box 200. When the drone battery starts to spontaneously combust and catch fire in the charging cabinet, the hot aerosol fire extinguishing device 132 is activated to spray aerosol fire extinguishing agent, quickly isolate the air and quickly cool down, and kill the fire in the early stage.

[0042] Two slide bars 141 with L-shaped cross sections are symmetrically arranged on the bottom plate 140 of the liner frame 100 on both sides of the width center line thereof, and a slideway is formed between the two slide bars 141 and the bottom plate 140 .

[0043] like Figure 3 As shown, the battery box 200 includes a box body 220 and a box cover 210 hinged to the box body 220 by a hinge, so that the box cover 210 can rotate on the box body 220. The box cover 210 and the box body 220 are both provided with a slider 214 with an L-shaped cross-section on the outer wall of a hinged side of the box cover 210 and the box body 220, and the two sliders 214 are arranged in parallel and slide with the slide. A positioning groove 222 is recessed on the outside of the box body 220 facing the rear cover 110, and the positioning groove 222 is provided with a charging concave interface 223 that can be docked with the charging convex interface 113. A charging socket 225 is installed on the side of the box body 220 facing the rear cover 110, and the charging socket 225 is electrically connected to the charging concave interface 223; at least one row of limit rings 215 is provided on the upper inner surface of the box cover 210 along the width direction of the box cover 210, as shown in FIG. Figure 4 and Figure 8As shown, in the embodiment, three rows of limiting rings 215 are arranged on the top of the box cover 210, and three limiting rings 215 are arranged in each row. Each limiting ring 215 is vertically slidably connected with an elastic fixing component 213, and the elastic fixing component 213 includes a bolt 2131, a limiting piece 2132, a spring 2133 and a support column 2134. The length of the support column 2134 is greater than the depth of the cavity of the box cover 210, and the lower end thereof is connected to a square piece 2136. The upper end of the support column 2134 passes through the box cover 210 through the limiting ring 215 and is connected to the limiting piece 2132 on the upper outer surface of the box cover 210 through the bolt 2131. The spring 2133 is sleeved on the square piece 2136 and the limiting ring 215. On the abutment column 2134 between, the outer diameter of the limiting ring 215 is larger than the spring 2133, so the upper part of the spring 2133 abuts against the lower part of the limiting ring 215, and the bolt 2133 fixes the limiting piece 2132 to the upper end of the abutment column 2134, and the length of the limiting piece 2132 is larger than the inner diameter of the limiting ring 215 to ensure that the upper height of the elastic fixing component 213 is always greater than or equal to the upper surface height of the box cover 210. When the battery box 200 is not placed or fixed with the drone battery, under the action of the elastic force of the spring 2133, the elastic fixing component 213 is in the lowest position. At this time, the upper end of the abutment column 2134 is flush with the upper surface of the box cover 210, and the limiting piece 2132 is in contact with the upper surface of the box cover 210.

[0044] like Figure 6 As shown, the square pieces 2136 at the lower ends of the elastic fixing components 213 in each row of limiting rings 215 are connected into one body by a flexible fixing belt 216, and the connection method is gluing. The width of the flexible fixing belt 216 is the same as the lower part of the support column 2134, and the length is the width of a row of elastic fixing components 213. The fixing belt 216 is made of flexible material. When the heights of the elastic fixing components 213 in a row are inconsistent, the flexible fixing belt 216 can be bent appropriately to adapt to the current position of the elastic fixing component 213. After the battery box 200 is placed with the drone battery, the elastic fixing components 213 on each row are squeezed by the shape of the drone battery and slide up to different heights, so that the flexible fixing belt 216 is bent into a shape that fits the shape of the drone battery. Finally, the drone battery is fixed under the action of the elastic force of the spring 2133. The above method can enable the battery box 200 to place and fix drone batteries of different shapes and sizes.

[0045] A plurality of heat dissipation grooves 212 are provided at intervals on the top surface of the box cover 210, two hooks 211 are installed on the outside of the switch surface of the box cover 210 facing the hinge near the lower edge, and a buckle 221 cooperating with the hook 211 is installed on the outside of the side surface of the box body 220 located directly below the switch surface of the box cover 210 near the upper edge.

[0046] like Figure 3As shown, a handle 226 is installed on one side of the box body 220 in the width direction, a mounting groove is provided at one end of the front side of the handle 226, and a locking block 2261 is movably installed in the mounting groove through an elastic mechanism, and a clamping block 2262 is connected to the locking block 2261 and can be extended out of the mounting groove. The bottom plate 140 of the inner liner frame 100 is provided with a block 142 located between the two slide bars 141 and engaged with the block 2262 at the edge of the open portion, and the height of the block 142 is lower than the height of the slider 214 on the box body 220, and the length of the block 142 is smaller than the width of the slideway on the bottom plate 140. Under the action of the elastic force of the elastic mechanism, when there is no external force, the locking block 2261 is at the edge of the handle 226, so that the card block 2262 is exposed outside the handle 226. When the battery box 200 needs to be removed, the locking block 2261 only needs to be slid toward the inside of the handle 226 to shrink the card block 2262 into the handle 226, and the battery box 200 can be taken out.

[0047] The inner bottom surface of the box body 220 is spaced apart with a plurality of box body heat dissipation grooves 227 which are opposite to the box cover heat dissipation grooves 212. Support ridges 224 which are opposite to the elastic fixing components 213 are convexly provided between adjacent box body heat dissipation grooves 227. The support ridges 224 have a trapezoidal cross-section and their positions correspond to the three rows of elastic fixing components 213 in sequence. They are used to cooperate with the elastic fixing components 213 to press the drone battery to ensure the reliable fixation of the drone battery.

[0048] The present invention provides an elastic fixing component 213 in the battery box 200. After drone batteries of different shapes and sizes are loaded into the battery box 200, the elastic fixing component 213 can slide up and down on the limit ring 216 using the support column 2134 according to the shape of the corresponding drone battery. With the deformation of the flexible fixing belt 216, it can adapt to the shape and size of various drone batteries, thereby realizing the placement and fixation of various drone batteries. After the battery is placed in the battery box 200, the battery charging line is plugged into the charging socket 225, and the battery box 200 is slidably plugged into the inner liner frame 100 using the slide bar 141 and the slideway, and charging can be started. There is no need to plug and unplug the charging line in a small space or in an uncomfortable posture. It is easy to use and safe and reliable. At the same time, it is convenient to set a hot aerosol fire extinguishing device in the inner liner to effectively reduce the fire hazard.

[0049] Of course, the above description is not limited to the above examples. Technical features not described in the present invention can be achieved by or by using existing technologies, which will not be described here. The above embodiments and drawings are only used to illustrate the technical scheme of the present invention and are not limitations of the present invention.
