[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0025] Embodiment 1:

[0026] like Figure 1-Figure 4 As shown, the battery pack charging seat structure described in this embodiment includes a seat body, and charging slots 11 are provided on two or three sides of the seat body 1. One end of the charging slot 11 has an opening, and the battery pack is inserted through the opening and positioned in the charging slot; the bottom surface of the charging slot 11 is provided with a buckle slot 4 corresponding to the elastic buckle block 100 on the bottom surface of the battery pack, and the outer edges of the corresponding two side walls are provided with limit blocks 22; a limit sliding channel 3 is formed between the limit block 22 and the bottom surface of the charging slot 11; the positive and negative electrode sheets 8 of the power supply that are plugged into the battery pack are installed on the side wall at one end of the charging slot 11. Refer to Figure 1 It can be seen that a charging slot is arranged on the two corresponding longitudinal sides of the base body, so that the base body can be placed vertically on the platform for charging, and two battery packs can be charged in the vertical state (if the base body is a hexagonal body, six battery packs can be charged vertically at the same time, if the base body is a rectangular parallelepiped or a cube, four battery packs can be charged vertically at the same time), which saves more space, is smaller in size, and is more convenient to carry.

[0027] When charging, insert the battery pack into the charging slot, insert the positioning strip on the battery pack into the limiting sliding through slot, snap the elastic buckle on the battery pack into the buckle slot, and insert the positive and negative power electrode plates into the long slot with copper sheets on the battery pack. The positive and negative power electrode plates are lapped with the copper sheets. The positive and negative power electrode plates are a positive copper sheet and a negative copper sheet, and a charging circuit board is inside the seat body.

[0028] In this embodiment, it further includes two or three U-shaped positioning blocks 2. The two or three U-shaped positioning blocks 2 are respectively fixed on two side surfaces or three side surfaces of the seat body 1. The inner cavity of the U-shaped positioning block 2 and the side surface of the seat body 1 form a charging slot 11. Limiting blocks 22 are arranged at the outer edges of the inner side walls of the two longitudinal parts of the U-shaped positioning block 2. Positive and negative power electrode plates 8 inserted into the battery pack are arranged on the inner side wall of the transverse block of the U-shaped positioning block 2. The buckle slot 4 is arranged on the side surface of the seat body 1 where the U-shaped positioning block 2 is fixed. Both the seat body and the U-shaped positioning block are made of plastic material to reduce weight and facilitate carrying out. Moreover, the U-shaped positioning block and the limiting block are combined with each other to form an integral structure. The U-shaped positioning block is fixed on the side surface of the seat body by screws, that is to say, the charging slot is formed immediately by fixing the U-shaped positioning block on the side surface of the seat body by screws.

[0029] In this embodiment, a U-shaped rib 9 protrudes from the side surface of the seat body 1 where the U-shaped positioning block 2 is fixed. The inner sides of the two longitudinal parts of the U-shaped rib 9 are closely attached to the outer sides of the two longitudinal parts of the U-shaped positioning block 2, and the inner side of the transverse part of the U-shaped rib 9 is closely attached to the outer side of the transverse part of the U-shaped positioning block 2 to position the U-shaped positioning block 2. The U-shaped rib and the seat body are combined with each other to form an integral structure. If the structure of the seat body is composed of a front shell and a rear shell, the front shell and the rear shell are symmetrically spliced and fixed. U-shaped ribs are formed on the peripheries of the outer side surfaces of the front shell, and U-shaped ribs are formed on the peripheries of the outer side surfaces of the rear shell. Moreover, the front shell and the U-shaped rib are combined with each other to form an integral structure, and the rear shell and the U-shaped rib are combined with each other to form an integral structure.

[0030] In this embodiment, it further includes a base 7, and the seat body 2 is arranged on the upper side surface of the base 7. This implementation method can combine the seat body and the base to form an integral structure, or the bottom end of the seat body can be fixed on the upper side surface of the base by screws or welding (ultrasonic welding).

[0031] In this embodiment, the upper side of the base 7 is provided with a positioning groove 73 corresponding to the bottom end of the base body 2, and the side wall of the positioning groove 73 has a plurality of plug-in blocks 1 71 and a plurality of slots 1 72. The side wall of the bottom end of the base body 1 has a plurality of slots 2 14 corresponding to the positions of the plug-in blocks 1 71 and a plurality of plug-in blocks 2 15 corresponding to the positions of the slots 1 72. After the bottom end of the base body 1 is correspondingly inserted into the positioning groove 73, the plug-in block 1 is correspondingly inserted into the slot 2, and the plug-in block 2 is correspondingly inserted into the slot 1. The base body is vertically inserted into the positioning groove, so that the battery pack is placed vertically for charging, and the positive and negative electrode sheets are at the lower end. Since the battery pack itself has a certain weight, the battery pack is more reliably in contact with the charger and is not easily affected by external vibration and other factors; at the same time, the base and the base body are two independent components, and the base can be quickly disassembled for easy storage.

[0032] In this embodiment, a plurality of heat dissipation holes 6 are respectively arranged on the sides, upper side and lower side of the seat body 1, and a through hole 731 corresponding to the heat dissipation holes 6 can be arranged at the bottom of the positioning groove 73 of the base 7, so that the seat body 7 has a sufficient height difference in the vertical direction, which is more conducive to air convection and reduces the temperature rise of the internal components of the charger; if the structure of the seat body is composed of a front shell and a rear shell, and the front shell and the rear shell are symmetrically assembled and fixed to each other, then a plurality of heat dissipation holes are arranged on the sides, upper side and lower side of the front shell and the sides, upper side and lower side of the rear shell.

[0033] In this embodiment, a charging indicator light 5 is provided beside each charging slot 11, and the charging indicator light 5 is provided on the base body. The charging indicator light is an LED charging indicator light, which is controlled by a circuit board for charging inside the base body and gives a user a prompt through different light colors when in standby, charging, and fully charged.

[0034] In this embodiment, a slope 221 is provided on the inner side surface of the limiting block 22 at the opening position facing the charging slot, and the slope 221 enlarges the insertion opening size of the limiting sliding channel, making it easier for the positioning bar of the battery pack to be inserted into the limiting sliding channel.

[0035] In addition, the side wall of the charging slot 11 at the position of the limit block 22 has a locking groove 23. The locking groove is used for a battery pack with an elastic buckle on the side. When the battery pack is inserted into the charging slot, the side elastic buckle is buckled into the locking groove.

[0036] In addition, when the structure of the base 1 is composed of a front shell 12 and a rear shell 13 that are symmetrically assembled and fixed to each other, so as to facilitate the installation of a circuit board for charging, the circuit board selected in this embodiment is a conventionally used circuit board (composed of a charging circuit and a discharging circuit), and a cable with a plug can be connected to the circuit board, and the cable can be positioned on the base 1; and based on the fact that grooves are provided on the sides of each charging slot 11 on the base 1, the charging indicator light 5 is installed in the groove 16, and the notch of the groove 16 is covered with a light-transmitting plate 10, so charging slots are provided on both the front shell and the rear shell, thereby concluding that grooves are provided on the sides of the charging slot of the front shell and the sides of the charging slot of the rear shell.

[0037] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone can derive other various forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, all technical solutions that are the same or similar to those of the present application fall within the protection scope of the present invention.
