[0031] The following is combined with Figures 1 to 6 The present invention is further described in detail, but is not intended to limit the present invention.

[0032] like Figure 1 and 2 As shown in Figure 3, in one embodiment of the present invention, the battery charging device includes a box body 1 and at least one charging compartment 2; a circulation cavity 101 is provided in the box body 1; the circulation cavity 101 can be communicated with the outside of the box body 1; at least one mounting hole 102 is also provided on the box body 1; the number of the charging compartments 2 corresponds to the number of the mounting holes 102; and the charging compartments 2 are connected to the corresponding mounting holes 102; a placement cavity 201 connected to the circulation cavity 101 is provided in the charging compartment 2; the placement cavity 201 is used to place the battery body 8; a limiting mechanism 200 is provided in the placement cavity 201; the limiting mechanism 200 is used to limit the connection with the battery body 8.

[0033] The technical solution of the present invention can realize independent charging of one or more battery bodies by arranging one or more charging compartments on the same box body, thereby improving the charging speed and stability, and reducing the space occupied by the battery body charging to a certain extent, thereby improving the rationality of use and ensuring the charging stability and efficiency; the corresponding battery body being charged is also limitedly assembled by a limiting mechanism, which can effectively reduce the shaking of the battery body, thereby improving the safety and stability of charging.

[0034] The number of mounting holes 102 is greater than or equal to the number of charging bays 2; preferably, the number of mounting holes 102 is equal to the number of charging bays 2. In other words, this structure can ensure the same installation convenience as the charging bay 2, and can also effectively achieve compactness and rationality of structural assembly.

[0035] Specifically, in some embodiments, Figure 1 and 2 As shown, the box body 1 includes a housing 11 and a mounting plate 12 connected to one side of the housing 11; and the circulation cavity 101 is formed between the housing 11 and the mounting plate 12; all the charging compartments 2 are arranged on the housing 11. This structure can increase the fluid circulation flow rate by removing the mounting plate 12 by assembling all the charging compartments 2 on the housing 11, thereby improving the heat dissipation effect; and improving the safety and stability of charging. Among them, as Figure 1 and 2 As shown, the housing 11 is provided with a mounting groove 111; a handle 112 is fixed in the mounting groove 11. By adding the handle 112 in the recessed mounting groove 111, this structure can effectively ensure the flatness of the surface of the box 1, thereby improving the stability of stacked boxes 1; and the handle 112 can also facilitate the transportation of a single box.

[0036] Specifically, in some embodiments, Figure 2 As shown, at least one smoke sensing component 3 is provided inside the housing 11 (circulation chamber 101). The smoke sensing component 3 can detect whether spontaneous combustion or other phenomena occur during the charging process in real time, thereby improving the safety and stability of charging.

[0037] Specifically, in some embodiments, Figure 1 As shown, the outer surface of the mounting plate 12 is provided with a guide groove 121; at least one circulation hole 122 is provided in the guide groove 121; one end of the circulation hole 122 is connected to the circulation cavity 101; the other end of the circulation hole 122 is connected to the outside of the box 1. Particularly, a (reversible) circulation fan is provided on the inner surface of the mounting plate 12; the circulation fan is connected to the circulation hole 122. Furthermore, the circulation fan is arranged at one side opening of the circulation hole 122. This structure enables the hot fluid generated in the circulation cavity 101 to be discharged through the circulation hole 122 through the circulation fan at the inner end of the circulation hole 122; at the same time, the cold fluid guided by the guide groove 121 is quickly and sufficiently discharged from the circulation hole 122 and the circulation fan to the charging bin to realize a circulating heat exchange operation.

[0038] Specifically, in some embodiments, Figure 1 and2 As shown, a safety switch 6 is provided inside the circulation chamber 101; all the charging compartments 2 are electrically connected in parallel; and the charging compartments 2 are electrically connected to the safety switch 6; the housing 1 (middle housing 11) is provided with at least one through-hole 113; a reset switch 4 and / or a power switch 5 are fixed in the through-hole 113; and the reset switch 4 is electrically connected to the safety switch 6; and the power switch 5 is electrically connected to the safety switch 6.

[0039] Specifically, in some embodiments, Figure 1 and 2 As shown, the limiting mechanism 200 includes a limiting protrusion 23; the limiting protrusion 23 is connected to the inner wall of the charging compartment 2 and protrudes from the inner wall of the charging compartment 2 toward the placement cavity 201. The limiting protrusion 23 is configured to abut the battery body 8. This abutment structure improves the assembly stability and convenience of the battery body 8, ensures assembly stability, and improves charging safety.

[0040] Specifically, in some embodiments, Figure 2 and 3 As shown, the top side of the charging compartment 2 is surrounded by a convex edge 21; the convex edge 21 is detachably connected to the box body 1 (the middle housing 11). Figure 4 and 5 As shown, the inner surface of the convex edge 21 is provided with at least one positioning post 211; the positioning post 211 is clamped on the charging compartment 2. This structure can improve the accuracy and convenience of assembly through the positioning post 211, thereby improving the operating efficiency.

[0041] Specifically, in some embodiments, Figure 5 and 6As shown, the charging compartment 2 is provided with an assembly hole 24; a charging connector is fixed in the assembly hole 24; the charging connector is used to connect to the battery body 8. A circuit board 9 is connected to the end of the charging connector away from the placement cavity 201. Furthermore, the charging connector can be a battery charging terminal connector; further, the model can be XT60H-F / M, etc.; the model of the circuit board 9 can be HW-A16; the chip on the HW-A16 can be the AC6956C4 chip; and the circuit boards 9 corresponding to all charging compartments 2 are arranged in parallel and are all electrically connected to the safety switch 6.

[0042] Specifically, in some embodiments, Figure 5 and 6 As shown, the side of the charging compartment 2 is also provided with at least one heat dissipation channel 25; the two sides of the heat dissipation channel 25 are respectively connected to the circulation cavity 101 and the placement cavity 201. This structure can increase the flow rate of the heat dissipation medium, thereby improving the heat dissipation effect and ensuring safety and stability in use.

[0043] Specifically, in some embodiments, Figure 2 and 3 As shown, the limiting mechanism 200 also includes a baffle plate 7; a rotating column 71 is provided at the side end of the baffle plate 7; a limiting channel 22 is provided at the side end of the charging compartment 2; the rotating column 71 is movably connected to the interior of the limiting channel 22 to allow the baffle plate 7 to rotate toward the interior of the placement cavity 201 and / or toward the exterior of the charging compartment 2; and the inner surface of the baffle plate 7 is used to abut the battery body 8. This structure prevents the battery body from falling out of the placement cavity during charging by the limiting and blocking effect of the baffle plate 7, thereby improving charging stability; and the rotatability of the baffle plate 7 can improve the convenience of inserting and removing the battery body.

[0044] Specifically, in some embodiments, Figure 3 and 4 As shown, the limiting channel 22 includes a horizontal section 223, a limiting recessed section 221 and a longitudinal section 222; the limiting recessed section 221 is connected and arranged between the horizontal section 223 and the longitudinal section 222; and the horizontal section 223 is horizontally arranged on the charging compartment 2; the longitudinal section 222 is vertically arranged on the charging compartment 2; and the rotating column 71 can be clamped in the interior of the limiting recessed section 221; the rotating column 71 can be movably connected to the interior of the horizontal section 223; the rotating column 71 can be movably connected to the interior of the longitudinal section 222. Figure 4As shown, the limiting recessed section 221 is an arc-shaped recessed section; the horizontal section 223 is a straight-line channel; and the longitudinal section 222 is a curved channel. In other words, in one method, before inserting the battery body 8, the rotating column 71 is moved from the limiting recessed section 221 to the horizontal section 223, and then the baffle plate is rotated toward the outside of the charging compartment 2; the battery body 8 is then inserted into the placement cavity 201; and finally, the rotating column 71 is restored from the horizontal section 223 to the limiting recessed section 221 to achieve the limiting of the battery body 8. In other methods, before inserting the battery body 8, the rotating column 71 is moved from the limiting recessed section 221 to the bottom of the longitudinal section 222, and then the baffle plate 7 is rotated toward the inside of the placement cavity 201; and the battery body 8 is then inserted into the placement cavity 201 to achieve the limiting assembly function of the baffle plate 7 at the side end and the limiting protrusion 23 on the battery body, preventing it from falling off, thereby ensuring the stability of charging.
