[0031] In addition, in the description of the specification and appended claims of this application, the terms "first", "second", "third", etc. are only used for differential description and cannot be construed as indicating or implying relative importance.

[0032] As Figures 1-3 shown, a battery charging box provided by an embodiment of this application will now be described. The battery charging box includes a feeding structure 1, a charging structure 2, a discharging structure 3, and a sorting structure 4. The feeding structure 1 is disposed above the charging structure 2, the discharging structure 3 is disposed below the charging structure 2, and the sorting structure 4 is disposed between the charging structure 2 and the discharging structure 3 for classifying batteries of different models. In this embodiment, the discharging structure 3 can be detachably placed on a bracket 5, and the bracket 5 can be fixed on a fixed surface such as a wall, and the bracket 5 can be in a detachable manner such as by screws. It is convenient for the user to install the battery charging box at the required position.

[0033] In this embodiment, it is described that the battery charging box can charge two models of batteries. On this basis, the corresponding structure can be expanded as needed to adapt to three or more models of batteries, which will not be described in detail here.

[0034] As Figure 1 and Figure 2As shown in the figure, the feeding structure 1 includes a housing and an internal feeding frame. The top of the feeding structure 1 is provided with an inlet for two models to be put in. A dust-proof cover that can be opened and closed can be set at the inlet. The dust-proof cover is normally in a closed state, and the battery model identification can be set on the outer surface of the dust-proof cover for users to conveniently determine which corresponding model of battery to put in. Correspondingly, there are at least two corresponding guiding channels inside the feeding structure 1, and the outlet of the guiding channel is docked with the battery inlet of the charging structure 2 below.

[0035] Correspondingly, the charging structure 2 includes a housing and an internal charging frame 20. The top of the charging structure 2 is provided with a battery inlet, and there is a battery discharging port 22 inside. There are two charging components for charging different models of batteries in the charging frame 20. The charging component includes a rotatably arranged battery accommodating member 21 and a driving member for driving the battery accommodating member 21 to rotate. The driving member adopts a motor and gear method or other structures that can drive the battery accommodating member 21 to rotate, which is not limited here. The battery accommodating member 21 is arranged between the battery discharging port 22 and the battery inlet.

[0036] The battery accommodating member 21 is of a cylindrical structure and is provided with at least two accommodating ports at equal arc distances. In this embodiment, three are set, and the accommodating ports have openings. When the accommodating port is docked with the upper battery inlet, the battery rolling down from the feeding structure 1 can automatically roll into the accommodating port. Correspondingly, there are two charging positions in the charging frame 20, and two batteries of the same model can be charged simultaneously. The charging positions are in the 2 o'clock - 5 o'clock direction, avoiding the battery inlet and the battery discharging port 22; Circuit boards are respectively provided on the side walls at the axial two ends of the accommodating port of the charging position, and electrode sheets are provided on each circuit board; When the battery accommodating member 21 rotates to this charging position, the positive and negative electrodes of the battery are respectively in contact with the corresponding electrode sheets, so that charging can be carried out. When the battery accommodating member 21 rotates to make the accommodating port dock with the battery discharging port 22, the fully charged battery automatically falls into the sorting structure 4 through the battery discharging port 22. In this embodiment, a detection circuit is also provided on the circuit board. When a damaged battery rotates to the charging position but cannot be charged, at this time the battery accommodating member 21 continues to rotate and drops it into the sorting structure 4.

[0037] Among them, the discharging structure 3 is used for classifying and collecting fully charged batteries of different models and invalid batteries. Correspondingly, the discharging structure 3 includes a housing and a discharging frame. There are multiple temporary storage bins 32 in the discharging frame. The temporary storage bins 32 include a waste bin, a first model collection bin, and a second model collection bin from top to bottom; The inlets 31 of the waste bin, the first model collection bin, and the second model collection bin are located below the sorting structure 4. Removable drawers are respectively provided in the waste bin, the first model collection bin, and the second model collection bin for the convenience of users to take.

[0038] In this embodiment, as Figures 2-6As shown, the sorting structure 4 is arranged in the charging frame 20 of the charging structure 2 and is located below the battery discharging port 22.

[0039] Specifically, the sorting structure 4 includes: a driving component and a sorting frame 40. The sorting frame 40 is slidably arranged in the charging frame 20 of the charging structure 2. The sorting frame 40 is provided with sorting grooves. The driving component is arranged on the charging frame 20 and is in transmission connection with the sorting frame 40. The driving component drives the sorting frame 40 to reciprocate, so that the sorting grooves communicate with the corresponding discharging port 22 of the charging structure 2 and the feeding port 31 of the discharging structure 3.

[0040] As can be seen from the above description, in this embodiment, two types of batteries can be charged. However, there are cases where the batteries put in by the user are ineffective, which are called waste batteries. Therefore, in this embodiment, there are three sorting grooves arranged side by side, namely a waste battery sorting groove 41, a first model sorting groove 42, and a second model sorting groove 43. Correspondingly, as Figure 2 shown, two battery accommodating members 21 are provided. One is used to charge the first model battery, and the other is used to charge the second model battery. In this embodiment, the waste bin is located below the battery accommodating member 21 for charging the first model battery. In this embodiment, the left battery accommodating member 21 is used to charge No. 7 batteries, and the right battery accommodating member 21 is used to charge No. 5 batteries.

[0041] In a preferred embodiment, the first model sorting groove 42 is arranged between the waste battery sorting groove 41 and the second model sorting groove 43, and the width of the first model sorting groove 42 is smaller than the width of the second model sorting groove 43. The waste battery sorting groove 41 and the second model sorting groove 43 have the same size. The first model sorting groove 42 only allows the first model batteries to pass through, the second model sorting groove 43 allows the second model batteries to pass through, and the waste battery sorting groove 41 allows the first model and second model batteries to pass through. Taking specific models as an example, the first model sorting groove 42 is used to carry No. 7 batteries, the second model sorting groove 43 is used to carry No. 5 batteries, and the waste battery sorting groove 41 is used to carry ineffective No. 5 and No. 7 batteries. The plane between the waste bin and the feeding port 31 of the first model collection bin is horizontal. The feeding ports 31 of the first model collection bin and the second model collection bin are separated by a partition block. In this embodiment, the battery discharging ports 22 of the two battery accommodating members 21 are both inclined towards the symmetry line between them.

[0042] In the actual process, the user puts the battery of the corresponding model into the inlet of the feeding structure 1. After being guided by the guiding channel, it falls into the accommodating port of the corresponding battery accommodating member 21. The battery accommodating member 21 rotates to drive the battery to the charging position. First, it is detected whether the battery is a normal battery. If it is a normal battery, charging continues; if it is a defective battery, the battery accommodating member 21 continues to rotate. At the same time, the driving assembly drives the sorting frame 40 to slide, and aligns the waste battery classification slot 41 with the battery discharging port 22 where there is a waste battery. When the battery automatically falls from the accommodating port into the lower waste battery classification slot 41, if the battery is a No. 7 battery, the battery automatically falls into the waste bin under the guiding action of the waste battery classification slot 41. If the battery is a No. 5 battery, the driving member drives the sorting frame 40 to move to the left. Under the action of the above horizontal plane, the battery will not fall out of the waste battery classification slot 41 until the sorting frame 40 moves to the position where the waste battery classification slot 41 is docked with the feeding port of the waste bin, and the waste battery automatically falls into the waste bin.

[0043] Similarly, when the normal battery is fully charged, if the battery is a No. 5 battery, the driving assembly drives the sorting frame 40 to slide and aligns the second model classification slot 43 with the corresponding battery discharging port 22. At this time, the above-mentioned partition block is located below the second model classification slot 43. After the docking is completed, the battery accommodating member 21 rotates and makes the No. 5 battery fall into the second model classification slot 43. Since the size of the first model classification slot 42 is smaller than that of the No. 5 battery and with the cooperation of the partition block, the No. 5 battery will not be stuck at the feeding port 31 of the first model collection bin. The driving assembly drives the sorting frame 40 to slide to the right until the second model classification slot 43 is docked with the feeding port 31 of the second model collection bin, and the fully charged No. 5 battery automatically falls into the second model collection bin for temporary storage. Similarly, if the battery is a No. 7 battery, the driving assembly drives the sorting frame 40 to slide and aligns the first model classification slot 42 with the corresponding battery discharging port 22. At this time, the lower part of the first model classification slot 42 is blocked by the above-mentioned horizontal plane, and when the No. 7 battery falls into the first model classification slot 42, it can roll on the horizontal plane. The driving assembly drives the sorting frame 40 to slide to the right until the first model classification slot 42 is docked with the feeding port 31 of the first model battery collection bin, and the No. 7 battery automatically falls into the first model battery collection bin for collection.

[0044] As Figure 5 and Figure 6 shown, in this embodiment, the length of the first model classification slot 42 gradually decreases from top to bottom, and its purpose is to better adapt to the length of the first model battery. The cross-section of the classification slot is rectangular, and each classification slot is formed by a partition board 44.

[0045] As Figure 5As shown, in a specific embodiment, the driving component includes a motor 45 and a transmission member that is drivingly connected to the output shaft of the motor 45. The transmission member is connected to the sorting frame 40. Among them, the transmission member includes a gear 46 and a rack 47. The gear 46 is arranged on the output shaft of the motor 45, and the rack 47 is arranged on the sorting frame 40. The forward and reverse rotation of the motor 45 can achieve the left and right reciprocating sliding of the sorted ore through the meshing of the gear 46 and the rack 47. In this embodiment, the rack 47 is arranged at the top or bottom of the sorting frame 40. The driving component uses the method of the gear 46 and the rack 47 to drive the sorting frame 40 to reciprocate, which can reduce the occupied space of the driving component, simplify the installation difficulty and ensure the stability of the reciprocating sliding. Of course, in order to ensure the accuracy of the left and right sliding positions of the sorting frame 40, sensors can be arranged at the corresponding positions on the charging frame 20, and the sensors are used to position the position to ensure the progress of the classification slot docking.

[0046] In another embodiment, the transmission member includes a synchronous belt, synchronous pulleys and a clamping member. Two synchronous pulleys are provided, one is arranged on the charging frame 20, and the other is arranged on the output shaft of the motor 45. The synchronous belt is meshingly connected to the two synchronous pulleys. The clamping member is fixed on the sorting frame 40 and is clamped and fixed with the synchronous belt. Of course, the transmission member can also adopt the form of a chain.

[0047] In other embodiments, the driving component is a lead screw assembly, and the lead screw assembly is a conventional structure, which will not be described in detail here.

[0048] The above-described embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be included in the protection scope of the present application.
