[0032] like Figure 1-Figure 3 As shown, the battery charging box 1 includes a feeding module 10, a charging module 20 and a discharging module 30.

[0033] The feed module 10 is used to store batteries to be charged. The feed module 10 includes a feed bin 11 (as the outer shell of the feed module 10). The batteries to be charged can flow into the feed bin 11 from the entrance of the feed bin 11.

For example, the outer contour shape of the feed bin 11 can be, but not limited to, a rectangular parallelepiped or a cylindrical shape; the specific preparation material of the feed bin 11 is not limited here, and the designer can reasonably choose it according to actual needs. For example, the preparation material of the feed bin 11 can be, but not limited to, PC (polycarbonate).

[0034] The charging module 20 is used to charge the battery to be charged. The charging module 20 includes a charging compartment 21. The charging compartment 21 serves as the outer shell of the charging module 20. The specific shape of the charging compartment 21 is not limited here. Designers can make reasonable designs according to actual needs. For example, the outer contour shape of the charging compartment 21 can be, but is not limited to, a quasi-rectangular or quasi-cylindrical shape. The specific preparation material of the charging compartment 21 is not limited here. Designers can make reasonable choices according to actual needs. For example, the preparation material of the charging compartment 21 is plastic or one of plastics. By designing the preparation material of the charging compartment 21 to be plastic or plastic, the cost of the battery charging box 1 can be effectively reduced.

[0035] The inlet of the charging bin 21 is connected to the outlet of the feeding bin 11 , so that the batteries to be charged can flow out of the feeding bin 11 from the outlet of the feeding bin 11 and flow into the charging bin 21 from the inlet of the charging bin 21 .

[0036] The charging bin 21 is detachably connected to the feed bin 11, that is, the charging bin 21 and the feed bin 11 are separately arranged; wherein, the charging bin 21 can be but is not limited to being detachably connected to the feed bin 11 by means of snap-in, plug-in, screw connection or magnetic adsorption, and the specific detachable connection method between the charging bin 21 and the feed bin 11 will be introduced in detail below.

[0037] like Figure 1-Figure 3 As shown, the discharge module 30 is used to store fully charged batteries, and the discharge module 30 includes a discharge bin 31 (as the outer shell of the discharge module 30); the specific shape of the discharge bin 31 is not limited here, and the designer can make a reasonable design according to actual needs.

For example, the preparation material of the discharge bin 31 can be but not limited to PC (polycarbonate).

[0038] The inlet of the discharge bin 31 is connected to the outlet of the charging bin 21 , so that fully charged batteries can flow out of the charging bin 21 from the outlet of the charging bin 21 and flow into the discharge bin 31 from the inlet of the discharge bin 31 .

[0039] The discharge bin 31 is detachably connected to the charging bin 21, that is, the discharge bin 31 and the charging bin 21 are separately arranged; wherein, the discharge bin 31 can be but is not limited to being detachably connected to the charging bin 21 by means of snap-in, plug-in, screw connection or magnetic adsorption, and the specific detachable connection method between the discharge bin 31 and the charging bin 21 will be introduced in detail below.

[0040] The charging bin 21 is located between the feed bin 11 and the charging bin 21, that is, the feed bin 11, the charging bin 21 and the discharge bin 31 are arranged in a "straight" shape. By arranging the charging bin 21 between the feed bin 11 and the discharge bin 31, the feed bin 11, the charging bin 21 and the discharge bin 31 are stacked in sequence, so that the battery to be charged flows into the feed bin 11 from the entrance of the feed bin 11, flows out of the feed bin 11 through the outlet of the feed bin 11 and flows into the charging bin 21 from the entrance of the charging bin 21, until the battery to be charged is fully charged, the fully charged battery flows out of the charging bin 21 from the outlet of the charging bin 21 and flows into the discharge bin 31 from the entrance of the discharge bin 31, thereby realizing the charging process of the entire battery to be charged.

[0041] It should be noted that, in addition to the above-mentioned feed bin 11, the feed module 10 may also include a feeding structure (a mechanical structure for delivering the battery to be charged into the feed bin 11, which is not described in detail here); in addition to the above-mentioned charging bin 21, the charging module 20 may also include a charging structure (a mechanical structure for charging the battery to be charged, which is not described in detail here); in addition to the above-mentioned discharging bin 31, the discharging module 30 may also include a discharging structure (a mechanical structure for delivering the fully charged battery out of the discharging bin 31, which is not described in detail here).

Therefore, the feeding bin 11 and the charging bin 21 are detachably connected, which can realize the detachable connection between the whole feeding module 10 and the whole charging module 20; similarly, the charging structure and other structural parts are assembled together with the above-mentioned charging bin 21 to form a whole charging module 20, and the discharging structure and other structural parts are assembled together with the above-mentioned discharging bin 31 to form a whole discharging module 30. Therefore, the charging bin 21 and the discharging bin 31 are detachably connected, which can realize the detachable connection between the whole charging module 20 and the whole discharging module 30.

[0042] Based on the battery charging box 1 in the embodiment of the present application, by designing a detachable connection between the feed bin 11 and the charging bin 21, a detachable connection between the entire feed module 10 and the entire charging module 20 can be achieved, so that the user can replace the damaged feed module 10 or the charging module 20 in time, without having to scrap the entire battery charging box 1 due to damage to the feed module 10 or the charging module 20, effectively avoiding waste of resources; by designing a detachable connection between the charging bin 21 and the discharging bin 31, a detachable connection between the entire charging module 20 and the entire discharging module 30 can be achieved, so that the user can replace the damaged charging module 20 or the discharging module 30 in time, without having to scrap the entire battery charging box 1 due to damage to the charging module 20 or the discharging module 30, effectively avoiding waste of resources; by designing the charging bin 21 between the feed bin 11 and the discharging bin 31, the feed bin 11, the charging bin 21 and the discharging bin 31 are arranged in a "single-line" shape, simplifying the spatial structural layout of the entire battery charging box 1.

[0043] Furthermore, if Figure 2-Figure 3 As shown, the feed bin 11 and the charging bin 21 are detachably connected by means of snap-on and / or screw-on connections. For example, the feed bin 11 and the charging bin 21 can be detachably connected only by snap-on connections; the feed bin 11 and the charging bin 21 can be detachably connected only by screw-on connections; the feed bin 11 and the charging bin 21 can be detachably connected by means of a combination of snap-on and screw-on connections. In this design, the feed bin 11 and the charging bin 21 are detachably connected by means of snap-on and / or screw-on connections, which facilitates users to replace damaged feed modules 10 or charging modules 20 in a timely manner.

[0045] Among them, the first clamping structure 40 is equivalent to the intermediate connecting structure between the feeding bin 11 and the charging bin 21. The specific form of the first clamping structure 40 is not limited here, and designers can make reasonable designs according to actual needs; for example, the first clamping structure 40 may include a first spring and a first wedge block. A first slide groove is provided at the edge of the feeding bin 11, one end of the first spring is fixedly connected to the bottom wall of the first slide groove, the first wedge block is slidably connected to the first slide groove and fixedly connected to the other end of the first spring, and the charging bin 21 is provided with a first clamping groove, and the first wedge block is clamped and connected to the first clamping groove to achieve relative fixation of the position between the feeding bin 11 and the charging bin 21.

[0046] Specifically, Figure 4 and Figure 5 As shown, the first clamping structure 40 includes a first clamping flange 41 and a first clamping groove 42. The first clamping flange 41 is provided on at least one of the feed bin 11 and the charging bin 21, and the first clamping groove 42 is provided on at least the other of the feed bin 11 and the charging bin 21. The first clamping flange 41 is clamped with the first clamping groove 42.

The first groove 211 can form a continuous annular groove around the entrance of the charging bin 21.

The second groove can form a continuous annular groove around the outlet of the charging bin 21. The second connection structure is an intermediate connection structure between the discharge bin 31 and the charging bin 21. The specific form of the second connection structure is not limited here, and the designer can make a reasonable design according to actual needs; for example, the second connection structure can include a second pin, the second connection part 312 is provided with a third socket corresponding to the second hole 213, the charging bin 21 is provided with a fourth socket corresponding to the second hole 213, and the second pin passes through the third socket and is plugged into the fourth socket (the outer surface of the second pin is interference fit with the hole wall of the third socket and the hole wall of the fourth socket).

[0059] Specifically, Fig. 9 and Fig.10 As shown, the second connecting portion 312 is provided with a second through hole 313 corresponding to the second hole 213, and the charging bin 21 is provided with a second threaded hole 215 corresponding to the second hole 213; the second connecting structure includes a second screw, and the second screw passes through the second through hole 313 and is connected to the second threaded hole 215. In this way, the second screw is threadedly connected with the second threaded hole 215 to realize the threaded connection between the discharge bin 31 and the charging bin 21, so that the position between the discharge bin 31 and the charging bin 21 is relatively fixed, which facilitates the assembly and disassembly between the discharge module 30 and the charging module 20.

[0060] Furthermore, if Figure 2and Figure 3 As shown, the discharge bin 31 is located on the side of the front of the battery charging box 1 and the charging bin 21 is located on the side of the front of the battery charging box 1 to achieve a detachable connection by means of a snap connection; the discharge bin 31 is located on the side of the back of the battery charging box 1 and the charging bin 21 is located on the side of the back of the battery charging box 1 to achieve a detachable connection by means of a screw connection. By designing the battery charging box 1 in the direction where the front of the battery charging box points to the back, the detachable connection between the discharge bin 31 and the charging bin 21 is achieved by means of a snap connection and a screw connection. On the one hand, the connection stability between the discharge module 30 and the charging module 20 can be ensured, and on the other hand, it is easy to achieve the installation and disassembly between the discharge module 30 and the charging module 20.
