[0020] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0021] Please refer to Figures 1-2 As shown, in the first aspect, this application proposes a feeding module 10, which is applied to a battery charging box 1. It can provide a space for batteries to be charged, so as to accommodate more batteries to be charged. The feeding module 10 has high overall structural strength and low assembly and processing difficulty.

[0022] The feeding module 10 is applied to the battery charging box 1, which also includes a charging module 20 for charging the battery to be charged. The feeding module 10 includes a feeding chamber 11; the feeding chamber 11 includes an outer feeding chamber 111 and an inner feeding chamber 112 for storing the battery to be charged; the feeding port of the outer feeding chamber 111 is correspondingly set with the feeding port of the inner feeding chamber 112, and the outer feeding chamber 111 covers the inner feeding chamber 112 and is engaged with the charging chamber 21 of the charging module 20 to press and position the inner feeding chamber 112 against the charging chamber 21 of the charging module 20.

[0023] The following combination Figures 1-10 The specific structure of the feeding module 10 will be described in detail.

[0024] like Figures 1-2 As shown, the feeding module 10 includes a feeding bin 11.

[0025] The feeding hopper 11 serves as the housing of the feeding module 10, and includes an outer feeding hopper 111 and an inner feeding hopper 112.

[0026] The outer feed chamber 111 serves as the outer shell of the feed hopper 11. The specific shape of the outer feed chamber 111 is not limited here; designers can design it reasonably according to actual needs. For example, the outer contour shape of the outer feed chamber 111 can be, but is not limited to, a cuboid or a cylinder. The specific material used to prepare the outer feed chamber 111 is also not limited here; designers can choose reasonably according to actual needs. For example, the material used to prepare the outer feed chamber 111 can be, but is not limited to, PC (polycarbonate).

[0027] The inner feeding chamber 112 serves as the inner shell of the feeding chamber 11 and is used to store batteries to be charged. The specific shape of the inner feeding chamber 112 is not limited here, and designers can make reasonable designs according to actual needs. For example, the outer contour shape of the inner feeding chamber 112 can be, but is not limited to, a cuboid or a cylinder. The specific material used to make the inner feeding chamber 112 is also not limited here, and designers can make reasonable choices according to actual needs. For example, the material used to make the inner feeding chamber 112 can be, but is not limited to, PC (polycarbonate).

[0028] The inlet of the outer feed chamber 111 is set to correspond to the inlet of the inner feed chamber 112, so that the batteries to be charged flow into the chamber of the inner feed chamber 112 sequentially from the inlet of the outer feed chamber 111 and the inlet of the inner feed chamber 112.

[0029] The outer feed chamber 111 covers the inner feed chamber 112 and engages with the charging chamber 21 of the charging module 20 (which serves as the housing of the charging module 20) to press and position the inner feed chamber 112 against the charging chamber 21 of the charging module 20. In other words, the outer feed chamber 111 clamps and fixes the inner feed chamber 112, which is embedded in its cavity, between itself and the charging chamber 21 of the charging module 20 by engaging with the charging chamber 21 of the charging module 20. Under the pressing force of the outer feed chamber 111, the inner feed chamber 112 can achieve a relatively fixed position with the charging chamber 21 of the charging module 20.

[0030] Specifically, such as Figures 2-5As shown, the outer feed compartment 111 has at least one of a locking block 1111 and a slot (not shown in the figure) on its edge near the charging compartment 21 of the charging module 20. The charging compartment 21 of the charging module 20 has at least another of a locking block 1111 and a slot on its edge near the outer feed compartment 111. The outer feed compartment 111 and the charging compartment 21 of the charging module 20 are relatively fixed in position by the locking block 1111 and the slot engaging. For example, the locking block 1111 can be set on both sides of the outer feed compartment 111 along the width direction YY' of the battery charging box 1, and the corresponding slot can be set on both sides of the charging compartment 21 of the charging module 20 along the width direction YY' of the battery charging box 1. In this case, the outer feed compartment 111 and the charging compartment 21 of the charging module 20 are engaged in the same direction along the width direction YY' of the battery charging box 1. For example, the card block 1111 can also be set on both sides of the outer feed chamber 111 along the length direction XX' of the battery charging box 1, and the corresponding card slot is set on both sides of the charging chamber 21 of the charging module 20 along the length direction XX' of the battery charging box 1. In this case, the outer feed chamber 111 and the charging chamber 21 of the charging module 20 are connected by a card along the length direction XX' of the battery charging box 1. For example, the card block 1111 can be set on both sides of the outer feeding chamber 111 along the width direction YY' of the battery charging box 1, or on both sides of the outer feeding chamber 111 along the length direction XX' of the battery charging box 1. The corresponding card slots are set on both sides of the charging chamber 21 of the charging module 20 along the width direction YY' of the battery charging box 1, and on both sides of the charging chamber 21 of the charging module 20 along the length direction XX' of the battery charging box 1. In this case, the outer feeding chamber 111 and the charging chamber 21 of the charging module 20 are engaged and connected along both the width direction YY' and the length direction XX' of the battery charging box 1. It should be noted that the card block 1111 can, but is not limited to, form an integral structure with the outer feeding chamber 111 and the charging chamber 21 of the charging module 20 by injection molding or 3D printing.

[0031] Based on the feeding module 10 in this embodiment, the inner feeding chamber 112 is designed to provide space for the batteries to be charged, thus accommodating more batteries. The outer feeding chamber 111 and the inner feeding chamber 112 are designed such that the outer feeding chamber 111 is nested within the inner feeding chamber 112, forming a nested double-shell structure. This effectively increases the structural strength of the feeding chamber 11, thereby enhancing the overall structural strength of the feeding module 10. By designing the outer feeding chamber 111 to engage with the charging chamber 21 of the charging module 20, the inner feeding chamber 112 embedded in its cavity is clamped and fixed between it and the charging chamber 21 of the charging module 20. Under the action of the clamping force of the outer feeding chamber 111, the inner feeding chamber 112 can achieve a relatively fixed position with the charging chamber 21 of the charging module 20. In this way, there is no need to design other structures to connect the inner feeding chamber 112 and the outer feeding chamber 111, which can effectively reduce the assembly difficulty and processing difficulty of the various components of the feeding module 10.

[0032] Furthermore, such as Figures 6-7 As shown, the inner feeding chamber 112 has a bottom surface 112a with a feeding port facing away from the outer feeding chamber 111. The bottom surface 112a includes a first surface 112b and a second surface 112c. The feeding port of the first surface 112b is further away from the outer feeding layer than the second surface 112c, so as to form a step at the bottom of the inner feeding chamber 112. The discharge port of the inner feeding chamber 112 is located on the first surface 112b. When the outer feeding chamber 111 is engaged with the charging chamber 21 of the charging module 20, the part where the discharge port of the inner feeding chamber 112 is located extends into the feeding port of the charging chamber 21 of the charging module 20, and the second surface 112c is used to abut against the outer surface of the charging chamber 21 of the charging module 20.

[0033] The first surface 112b and / or the second surface 112c can be a plane, a curved surface, or a combination of a plane and a curved surface. A height difference is formed between the first surface 112b and the second surface 112c, creating a stepped structure at the bottom of the inner feed chamber 112. Both the first surface 112b and the second surface 112c serve as stepped surfaces. When the outer feed chamber 111 engages with the charging chamber 21 of the charging module 20, the inner feed chamber 112 is positioned within the charging chamber 21 of the charging module 20 under the pressure of the outer feed chamber 111. The outlet portion of the inner feed chamber 112 protrudes beyond the plane of the second surface 112c to embed into the inlet of the charging chamber 21 of the charging module 20, allowing the battery to be charged to flow out of the inner feed chamber 112 from its outlet and into the charging chamber 21 from its inlet. When the outer feed chamber 111 is engaged with the charging chamber 21 of the charging module 20, the inner feed chamber 112 is positioned in the charging chamber 21 of the charging module 20 under the action of the outer feed chamber 111. The second surface 112c abuts against the outer surface of the charging chamber 21 of the charging module 20. Point contact, line contact or surface contact can be formed between the second surface 112c and the outer surface of the charging chamber 21 of the charging module 20.

[0034] When the outer feed chamber 111 engages with the charging chamber 21 of the charging module 20, the inner feed chamber 112 is positioned on the charging chamber 21 of the charging module 20 under the pressing force of the outer feed chamber 111. By designing the second surface 112c to abut against the outer surface of the charging chamber 21 of the charging module 20, the charging chamber 21 of the charging module 20 provides support for the inner feed chamber 112. In this way, the inner feed chamber 112 can better abut against the charging chamber 21 of the charging module 20 under the pressing force of the outer feed chamber 111, thereby effectively enhancing the stability of the inner feed chamber 112 placed on the charging chamber 21 of the charging module 20.

[0035] Furthermore, such as Figure 7As shown, there are two second surfaces 112c, which are located on opposite sides of the first surface 112b along the width direction YY' of the battery charging box 1. By distributing two second surfaces 112c on both sides of the first surface 112b along the width direction YY' of the battery charging box 1, when the outer feed chamber 111 is engaged with the charging chamber 21 of the charging module 20, the inner feed chamber 112 is positioned on the charging chamber 21 of the charging module 20 under the action of the pressing force of the outer feed chamber 111. At this time, both second surfaces 112c abut against the outer surface of the charging chamber 21 of the charging module 20, increasing the contact area between the inner feed chamber 112 and the charging chamber 21 of the charging module 20, so that the charging chamber 21 of the charging module 20 provides more effective support for the inner feed chamber 112. Thus, the inner feed chamber 112 can better abut against the charging chamber 21 of the charging module 20 under the action of the pressing force of the outer feed chamber 111, thereby further enhancing the stability of the inner feed chamber 112 placed on the charging chamber 21 of the charging module 20.

[0036] Furthermore, such as Figure 7 As shown, the second surface 112c is a plane, and the second surface 112c is provided with a hollow groove 112d. By designing the second surface 112c as a plane, when the outer feeding chamber 111 is engaged with the charging chamber 21 of the charging module 20, the inner feeding chamber 112 is positioned on the charging chamber 21 of the charging module 20 under the action of the pressing force of the outer feeding chamber 111. At this time, the second surface 112c abuts against the outer surface of the charging chamber 21 of the charging module 20 and forms a surface contact, so that the charging chamber 21 of the charging module 20 provides support for the inner feeding chamber 112, and the inner feeding chamber 112 can better press against the charging chamber 21 of the charging module 20 under the action of the pressing force of the outer feeding chamber 111, thereby further and effectively enhancing the stability of the inner feeding chamber 112 placed on the charging chamber 21 of the charging module 20. By designing a hollow groove 112d on the second surface 112c, the stability of the inner feed chamber 112 placed on the charging chamber 21 of the charging module 20 is ensured. At the same time, the hollow groove 112d also acts as a reinforcing rib to strengthen the structural strength of the bottom of the inner feed chamber 112, thereby enhancing the overall structural strength of the inner feed chamber 112. In addition, the design of the hollow groove 112d has the purpose of saving materials and reducing costs to a certain extent.

[0037] Furthermore, such as Figures 8-9As shown, the storage body 1121 includes a storage body 1121 and an abutment flange 1122; the storage body 1121 is used to store batteries to be charged; the abutment flange 1122 is bent and connected to the edge of the storage body 1121 where the feed inlet is located, and the end of the abutment flange 1122 away from the storage body 1121 abuts against the inner surface of the feed outer storage compartment 111, and a gap is formed between the inner surface of the abutment flange 1122 and the inner surface of the feed outer storage compartment 111. The feeding module 10 also includes a baffle (not shown in the figure), which is located within the gap and can move within the gap to open or close the feed inlet of the storage body 1121.

[0038] The abutment flange 1122 extends along the width direction YY' of the battery charging box 1. The abutment flange 1122 can be, but is not limited to, forming an integral structure with the box body 1121 by injection molding or 3D printing. Along the width direction YY' perpendicular to the battery charging box 1, the cross-section of the abutment flange 1122 can be, but is not limited to, being L-shaped or C-shaped.

[0039] The partition, serving as a cover for the feeding module 10, can be used to block the feed inlet of the chamber body 1121 to prevent uncharged batteries flowing into the chamber of the chamber body 1121 from flowing back out of the chamber of the chamber body 1121 through the feed inlet. The partition can move relative to the chamber body 1121 within the gap, allowing the feed inlet of the chamber body 1121 to switch between an open and closed state. It should be noted that, since the inlet of the outer feed chamber 111 corresponds to the inlet of the main body 1121, when the partition moves within the gap to open the inlet of the main body 1121, it also opens the inlet of the outer feed chamber 111. At this time, the battery to be charged can flow into the cavity of the main body 1121 sequentially from the inlet of the outer feed chamber 111 and the inlet of the main body 1121. Similarly, when the partition moves within the gap to close the inlet of the main body 1121, it also closes the inlet of the outer feed chamber 111. At this time, the battery to be charged cannot flow into the cavity of the main body 1121 sequentially from the inlet of the outer feed chamber 111 and the inlet of the main body 1121. For example, when the abutment flange 1122 extends along the width direction YY' of the battery charging box 1, the gap formed between the inner side of the abutment flange 1122 and the inner surface of the feed chamber 111 also extends along the width direction YY' of the battery charging box 1. At this time, the baffle moves within the gap along the width direction YY' of the battery charging box 1 to open or close the feed port of the chamber body 1121. It is worth mentioning that the baffle can, on the one hand, prevent the batteries to be charged that have flowed into the chamber of the chamber body 1121 from flowing back out of the chamber body 1121 from the feed port of the chamber body 1121, and on the other hand, prevent impurities such as dust from falling into the chamber of the chamber body 1121.

[0040] By designing a baffle, the baffle can be used to block the feed inlet of the chamber body 1121 to prevent the batteries waiting to be charged from flowing into the chamber of the chamber body 1121 from flowing back out of the chamber of the chamber body 1121 from the feed inlet; by designing the baffle in the gap formed between the inner side of the abutting flange 1122 and the inner surface of the feed outer chamber 111, the internal space of the feed outer chamber 111 is fully utilized, so that the components of the feed module 10 are arranged more compactly in space.

[0041] Furthermore, such as Figures 8-9 As shown, the partition includes a flexible baffle plate that can move within the gap to open or close the feed inlet of the bin body 1121. By designing the partition as a flexible baffle plate, the flexible baffle plate can be supported on the inner side of the abutment flange 1122. The user can open or close the feed inlet of the bin body 1121 by pushing or pulling the flexible baffle plate, which is simple, convenient and quick to operate. Of course, in other embodiments, the partition may also include a rigid baffle plate, which is located within the gap and can be slidably connected to the bin body 1121 to open or close the feed inlet of the bin body 1121.

[0042] Furthermore, such as Figure 6 and Figure 8 As shown, the feeding module 10 also includes a support structure 14 for supporting the flexible baffle. The support structure 14 is connected to the bin body 1121 and is located at least one of the feed inlets of the bin body 1121 along the movement direction of the flexible baffle.

[0043] The supporting structure 14 is used to support the flexible partition plate and provide support for it. The specific form of the supporting structure 14 is not limited here, and the designer can make a reasonable design according to the actual needs. For example, the supporting structure 14 may include a supporting roller, which is fixedly connected to the bin body 1121. The flexible partition plate is placed on the outer surface of the supporting roller. When the flexible partition plate moves in the gap, rolling friction is generated between the flexible partition plate and the supporting roller. It is understood that the flexible baffle can open and close the feed inlet of the silo body 1121 in a single-opening manner or in a double-opening manner. For example, when the flexible baffle opens and closes the feed inlet of the silo body 1121 in a single-opening manner, there is one flexible baffle and one supporting structure 14. In this case, the supporting structure 14 is located on one side of the silo body 1121 along the movement direction of the flexible baffle. As another example, when the flexible baffle opens and closes the feed inlet of the silo body 1121 in a double-opening manner, there are two flexible baffles and two supporting structures 14. In this case, the two supporting structures 14 are located on both sides of the silo body 1121 along the movement direction of the flexible baffle.

[0044] Specifically, such as Figure 6and Figure 8 As shown, the supporting structure 14 includes a supporting plate 141. One end of the supporting plate 141 is connected to the edge of the hopper body 1121 near the feed inlet of the outer feed hopper 111, and the supporting plate 141 is bent away from the feed inlet of the hopper body 1121. The supporting plate 141 can, but is not limited to, be integrally formed with the inner feed hopper 112 by injection molding or 3D printing. In this design, by designing the supporting plate 141 as a curved panel, the flexible baffle can fit more closely to the supporting plate 141, increasing the contact area between the flexible baffle and the supporting plate 141, thereby effectively improving the stability of the flexible baffle's movement within the gap.

[0045] Furthermore, such as Figure 6 , Figure 7 and Figure 10 As shown, the feeding module 10 also includes a guide structure 13, which is located in the cavity of the inner feeding chamber 112 and is detachably connected to the inner feeding chamber 112. The guide structure 13 is used to change the movement trajectory of the battery to be charged in the cavity of the inner feeding chamber 112 so that the battery to be charged is evenly distributed in the cavity of the inner feeding chamber 112.

[0046] The guide structure 13 guides the batteries to be charged as they flow into the inner feed chamber 112. When the batteries come into contact with the guide structure 13, their direction of movement changes, altering their trajectory within the inner feed chamber 112 and resulting in a more uniform arrangement of the batteries within the chamber. The guide structure 13 can be detachably connected to the inner feed chamber 112 via at least one of the following methods: screwing, snap-fitting, or plugging. It is understood that the guiding structure 13 can provide either dynamic or static guidance for the batteries to be charged. For example, when the guiding structure 13 provides dynamic guidance, it may include a conveyor belt. The direction of movement of the batteries to be charged changes under the guidance of the conveyor belt, thus altering their trajectory within the feed chamber 112. Alternatively, when the guiding structure 13 provides static guidance, it may include a guide groove. The direction of movement of the batteries to be charged changes under the guidance of the guide groove, thus altering their trajectory within the feed chamber 112. It should be noted that when the guiding structure 13 includes the aforementioned conveyor belt, there may be multiple conveyor belts with different conveying directions, pre-designed to guide different batteries to different positions under the action of different conveyor belts, thereby achieving a uniform arrangement of the batteries to be charged within the feed chamber 112. When the guide structure 13 includes the above-mentioned guide groove, there can be multiple guide grooves. The multiple guide grooves have different extension directions and are pre-designed so that different batteries to be charged are guided to different positions under the action of different guide grooves, thereby achieving uniform arrangement of batteries to be charged in the chamber of the inner feed hopper 112.

[0047] Furthermore, such as Figure 6 , Figure 7 and Figure 10 As shown, the first and second sides of the inner feeding chamber 112, which are arranged opposite each other along the length direction XX' of the battery charging box 1, are provided with multiple through holes. The guide structure 13 includes multiple guide rollers 131 and multiple fastening units 132; the guide rollers 131, fastening units 132, through holes on the first side and through holes on the second side are arranged in a one-to-one correspondence, and each fastening unit 132 passes through the corresponding through hole on the first side and the corresponding through hole on the second side and is connected to the corresponding guide roller 131, so that all guide rollers 131 are positioned in the inner feeding chamber 112 according to a preset arrangement.

[0048] The guide rollers 131 are arranged according to a preset layout, which is pre-designed by the designers. For example, the preset layout can be a regular matrix arrangement of multiple guide rollers 131 in an M-row * N-column configuration; or it can be an irregular arrangement of multiple guide rollers 131 in an M-row configuration, with the number of guide rollers 131 in each row decreasing compared to the previous row. It is worth noting that the guide rollers 131 can change the direction of movement of the battery to be charged, and they also act as reinforcing ribs, strengthening the structural strength of the feed chamber 112.

[0049] Specifically, such as Figure 10 As shown, each guide roller 131 has a locking hole 131a on both ends; each fastening unit 132 includes two locking pins 1321, one locking pin 1321 passing through the through hole on the first side and engaging with the locking hole 131a on one end face of the guide roller 131, and the other locking pin 1321 passing through the through hole on the second side and engaging with the locking hole 131a on the other end face of the guide roller 131, so as to position the guide roller 131 in the feeding chamber 112. By designing locking holes 131a on both ends of the guide roller 131, and the two locking pins 1321 passing through the through holes on the first and second sides and engaging with the locking holes 131a on both ends of the guide roller 131, the installation between the guide roller 131 and the feeding chamber 112 is realized, which is simple, convenient and quick to operate. Conversely, it also facilitates the disassembly between the guide roller 131 and the feeding chamber 112.

[0050] Please refer to Figure 2 As shown, the second aspect of this application proposes a battery charging box 1, which includes a charging module 20, a discharging module (not shown in the figure), and the aforementioned feeding module 10. The charging module 20 is used to charge the battery to be charged. The feeding port of the charging module 20 is connected to the discharging port of the feeding inner chamber 112. The discharging module is used to store fully charged batteries. The feeding port of the discharging module is connected to the discharging port of the charging module 20.

[0051] Based on the battery charging box 1 in this embodiment, the inner feeding compartment 112 is designed to provide space for the batteries to be charged, enabling the battery charging box 1 to accommodate more batteries. The outer feeding compartment 111 and the inner feeding compartment 112 are designed such that the outer feeding compartment 111 is nested within the inner feeding compartment 112, forming a nested double-shell structure. This effectively increases the structural strength of the feeding compartment 11, thereby enhancing the overall structural strength of the feeding module 10 and ultimately strengthening the overall structural strength of the battery charging box 1. By designing the outer feeding chamber 111 to engage with the charging chamber 21 of the charging module 20, the inner feeding chamber 112 embedded in its cavity is clamped and fixed between it and the charging chamber 21 of the charging module 20. Under the action of the clamping force of the outer feeding chamber 111, the inner feeding chamber 112 can achieve a relatively fixed position with the charging chamber 21 of the charging module 20. In this way, no additional structure needs to be designed to connect the inner feeding chamber 112 and the outer feeding chamber 111, which can effectively reduce the assembly difficulty and processing difficulty between the components of the feeding module 10, thereby reducing the overall assembly and processing difficulty of the battery charging box 1.
