It typically features constant current and constant voltage charging capabilities to ensure that the battery is not damaged during the charging process.

[0003] There are many types of power tools, such as electric drills, magnetic drills, electric reamers, electric knives, and electric shears. Power tools like handheld drills use a rechargeable portable lithium battery installed at the bottom for convenient use. When the portable lithium battery at the bottom of the handheld drill runs out of power, the battery is removed from the drill and plugged into a charger base to charge. Once the battery is fully charged, it is unplugged from the charger base and reinstalled on the drill for use.

[0004] In the existing technology, the lithium battery power supply is removed from the hand drill and then inserted into the charger base for charging. However, in order to meet the working needs of the hand drill, the movable lithium battery power supply is generally designed to be large. Therefore, when the lithium battery power supply is inserted into the charger base, if the charging position is moved or changed, the lithium battery power supply inserted into the charger base may slip off, causing the lithium battery power supply to be damaged by impact.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 As shown, this utility model is an intelligent lithium battery charger for electric appliances, including a charging compartment 1; a placement slot 14 is provided on the top of the charging compartment 1; a power supply 15 is fixedly connected inside the charging compartment 1; a power supply piece 8 is fixedly connected to the top of the power supply 15; multiple power supply pieces 8 are provided and pass through the placement slot 14; a fixing plate 7 is fixedly connected to one side of the top of the charging compartment 1 located in the placement slot 14; a support plate 13 is fixedly connected to the top of the charging compartment 1 located on the other side of the placement slot 14; a lead screw 12 is rotatably connected to the support plate 13; a moving plate 9 is fixedly connected to one end of the lead screw 12; and a rotating handle 16 is fixedly connected to the other end of the lead screw 12.

[0026] The de-energized lithium battery is removed from the hand drill and inserted into the placement slot 14 of the charging compartment 1. After insertion, the operator rotates the handle 16, causing the lead screw 12 to rotate on the support plate 13. The rotating lead screw 12 moves the moving plate 9, which cooperates with the fixed plate 7 to fix the lithium battery in the placement slot 14. This design prevents the lithium battery from slipping out of the charging compartment 1 when it is moved, thus avoiding damage. After the lithium battery is inserted into the placement slot 14, the power supply plate 8 inputs the power from the power supply transformer 15 to charge the lithium battery. The power supply transformer 15 can change the voltage, thus protecting the lithium battery.

[0027] Please refer to the attached image. Figure 2 , Figure 3 and Figure 4 As shown, specifically, a vertical plate 17 is fixedly connected inside the charging compartment 1; a rotating rod 19 is rotatably connected to the vertical plate 17; a drive motor 18 is fixedly connected to the vertical plate 17; the drive motor 18 is connected to the rotating rod 19; a fan blade 20 is fixedly connected to the rotating rod 19; during operation, the rotating rod 19 is driven by the drive motor 18 on the vertical plate 17 to rotate, and the rotating rod 19 drives the fan blade 20 to rotate, thereby dissipating heat from the power supply 15 inside the charging compartment 1, preventing the power supply 15 inside the charging compartment 1 from overheating and spontaneously combusting or accelerating the aging of the circuit.

[0028] Please refer to the attached image. Figure 1 , Figure 2 and Figure 5 As shown, specifically, the charging compartment 1 is provided with heat dissipation holes 2; there are two heat dissipation holes 2, which are symmetrically arranged on the charging compartment 1; during operation, by providing heat dissipation holes 2 on both sides of the charging compartment 1, the heat generated inside the charging compartment 1 can be smoothly discharged from the charging compartment 1, so that the charging compartment 1 can be cooled down.

[0029] Please refer to the attached image. Figure 1 , Figure 2 and Figure 5 As shown, specifically, a limiting groove 21 is fixedly connected inside the charging compartment 1; a dust cover 3 is slidably connected inside the limiting groove 21; a handle 4 is fixedly connected to the top of the dust cover 3; during operation, by setting the dust cover 3 inside the charging compartment 1, dust in the air or dust generated on the construction site is blocked from entering the charging compartment 1, thus preventing poor heat dissipation caused by dust accumulation in the charging compartment 1. When too much dust accumulates on the dust cover 3, the operator can pull the dust cover 3 out from the limiting groove 21 by holding the handle 4 for cleaning.

[0030] Please refer to the attached image. Figure 1 , Figure 2 and Figure 5 As shown, specifically, there are two dust shields 3, which are symmetrically arranged on the inner side of the charging compartment 1; the dust shields 3 are located on one side of the heat dissipation hole 2; during operation, by setting dust shields 3 on the heat dissipation holes 2 on both sides, the charging compartment 1 can dissipate heat and prevent dust from entering the charging compartment 1.

[0031] Please refer to the attached image. Figure 1 , Figure 4 and Figure 5As shown, specifically, a limiting block 10 is fixedly connected to the top of the charging compartment 1; two limiting blocks 10 are provided and symmetrically arranged on the top of the charging compartment 1; a limiting rod 11 is slidably connected inside the limiting block 10; one end of the limiting rod 11 is fixedly connected to the moving plate 9; during operation, by setting two limiting blocks 10 and limiting rod 11 on the top of the charging compartment 1, the purpose is to prevent the moving plate 9 from deflecting when the lead screw 12 drives the moving plate 9 to move. Therefore, by setting the limiting blocks 10 and limiting rod 11, the moving plate 9 can only move forward or backward and will not rotate with the lead screw 12.

[0032] Please refer to the attached image. Figure 4 and Figure 5 As shown, specifically, a power cord 6 is fixedly connected to the power transmitter 15; the power cord 6 passes through the charging compartment 1; the other end of the power cord 6 is fixedly connected to a power plug 5; during operation, the power plug 5 is inserted into the power socket, and then the power cord 6 transmits power to the power transmitter 15, which then transforms the voltage to transmit electrical energy from the power supply plate 8 to the lithium battery power supply to charge the lithium battery power supply.

[0033] The working principle of this utility model is as follows: A de-energized lithium battery is removed from the hand drill and inserted into the placement slot 14 of the charging compartment 1. After insertion, the operator rotates the handle 16, causing the lead screw 12 to rotate on the support plate 13. The rotating lead screw 12 moves the moving plate 9, which cooperates with the fixed plate 7 to fix the lithium battery in the placement slot 14. This design prevents the lithium battery from slipping out of the charging compartment 1 when it is moved, thus avoiding damage. After the lithium battery is inserted into the placement slot 14, the power supply plate 8 inputs power from the power transmitter 15 to charge the lithium battery. The power transmitter 15 can change the voltage, thus protecting the lithium battery.

[0034] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
