[0030] Combine the following Figure 1-Figure 5 A charger of the utility model includes a housing 100 , a battery compartment 200 and a locking structure 300 .

[0031] The battery compartment 200 is recessed on the side wall of the housing 100; in this embodiment, the housing 100 is a cubic structure, and the battery compartment 200 is arranged on the four side walls of the housing 100, and each battery compartment 200 corresponds to a locking structure 300. The battery compartment 200 and the housing 100 can be an integrally formed structure or a split connection structure. The battery compartment 200 is used to place the battery to be charged, and a charging terminal 201 for the battery to be docked is arranged in the battery compartment 200;

[0032] The locking structure 300 is arranged in the outer shell 100 and is located on one side of the battery compartment 200. The locking structure 300 includes a pressing portion 301, a connecting portion 302 and a locking portion 303. The pressing portion 301 is connected to the locking portion 303 through the connecting portion 302. One end of the locking portion 303 is movably penetrated through a side wall of the battery compartment 200. One end of the pressing portion 301 is movably penetrated through a side wall of the outer shell 100. When the pressing portion 301 is pressed, the locking portion 303 moves toward one side of the inner shell 100, and the movement directions of the pressing portion 301 and the locking portion 303 are parallel.

[0033] In this embodiment, the top of the outer shell 100 is recessed inward to form an installation groove 101, the installation groove 101 is located above the battery compartment 200, the locking structure 300 is located in the installation groove 101, and a surface cover 102 is provided on the top end surface of the installation groove 101; wherein, the outer shell 100, the battery compartment 200 and the installation groove 101 can be an integrally molded structure.

[0034] Furthermore, in this embodiment, the locking portion 303 movably penetrates the top side wall of the battery compartment 200 , and the pressing portion 301 movably penetrates the surface cover 102 and extends to the outside of the housing 100 .

[0035] In the embodiment, the connection part 302 includes a press-fit bracket 304 and a rocker plate 305. The press-fit bracket 304 is fixed in the installation slot 101. Furthermore, the press-fit bracket 304 is fixed in the installation slot 101 by screws, and a screw mounting hole for the screw to pass through is provided on the press-fit bracket 304. A sliding groove 306 with an opening facing downward is provided on one side of the pressing bracket 304, and a pressing portion 307 is provided downward on the other side. The rocker 305 is located at the lower side of the pressing bracket 304, and a rotating shaft 308 is provided on the side wall of the rocker 305. A supporting portion 103 is provided in the mounting groove 101. The pressing portion 307 abuts against the supporting portion 103 and the contact surfaces of the two are respectively provided with recessed portions. The two recessed portions together constitute a mounting hole. The rotating shaft 308 is movably sleeved in the mounting hole, so that the rocker 305 can rotate with the rotating shaft 308 as a fulcrum; specifically, the pressing portion 307 includes two pressing plates, and the supporting portion 103 includes two supporting rods. The pressing plates correspond to the supporting rods one by one, and the contact surfaces of the pressing plates and the supporting rods are provided with mounting holes for the rotating shaft 308 to rotate. The rocker 305 is located at the two The two side walls of the seesaw 305 are respectively provided with a rotating shaft 308 between the mounting holes, and the rotating shafts 308 on both sides are respectively located in the two mounting holes, thereby forming a stable rotating shaft 308 mounting structure, which is convenient for the seesaw 305 to realize the rotation function; the separable connection between the pressing part 307 and the support part 103 is convenient for the disassembly and assembly of the locking structure 300. During installation, the rotating shaft 308 of the seesaw 305 is first placed on the recessed part of the support part 103, and then the pressing bracket 304 is fixed in the mounting groove 101 by screws. At this time, the pressing part 307 is abutted against the support part 103, and the recessed part of the pressing part 307 and the recessed part of the support part 103 form a mounting hole for the rotating shaft 308 to rotate, and at the same time ensure that the seesaw 305 can rotate smoothly;

[0036] In the embodiment, the locking portion 303 includes a locking tongue 309 and a compression spring 310. The first end of the locking tongue 309 is located in the slide slot 306 and is connected to the top wall of the slide slot 306 through the compression spring 310. The second end of the locking tongue 309 movably penetrates the top side wall of the battery compartment 200 and extends into the battery compartment 200. The locking tongue 309 is slidably connected to the slide slot 306. A through slot 311 is provided on the locking tongue 309. The first end of the rocker 305 is located in the through slot 311 and abuts against the through slot 311. The second end of the rocker 305 abuts against the pressing portion 301.

[0037] In the embodiment, the pressing portion 301 includes a button 312, the first end of the button 312 abuts against the second end of the rocker 305, the second end of the button 312 movably passes through the surface cover 102 and extends to the outside of the shell 100, when the second end of the button 312 is pressed, under the conduction action of the rocker 305, the second end of the lock tongue 309 moves toward the inside of the installation groove 101, and a limit plate 313 is sleeved on the middle peripheral wall of the button 312, and the limit plate 313 is located inside the shell 100 to prevent the button 312 from completely extending out of the shell 100.

[0038] In the initial state, the second end of the lock tongue 309 extends into the battery compartment 200 under the action of the compression spring 310, and a limit portion is formed on the outer walls on both sides of the first end of the lock tongue 309 to limit the lock tongue 309 from fully extending into the battery compartment 200; when the second end of the lock tongue 309 is located in the battery compartment 200, if a battery is placed in the battery compartment 200, the lock tongue 309 forms a buckle limit structure for the battery to fix the battery in the battery compartment 200.

[0039] The seesaw 305 acts as a lever, and the length from the first end of the seesaw 305 to the rotating shaft 308 (i.e., the fulcrum) can be limited to be shorter than the length from the second end of the seesaw 305 to the rotating shaft 308. At the same time, the second end of the seesaw 305 is bent upward and abuts against the first end of the button 312. This design helps to reduce the pressing force on the button 312 to perform the unlocking operation. When unlocking, the second end of the button 312 is pressed to move the button 312 downward, and the second end of the seesaw 305 is pressed downward by the button 312. At the same time, under the action of the lever principle, the first end of the seesaw 305 moves upward and presses the lock tongue 309, so that the lock tongue 309 overcomes the force of the compression spring 310 and moves upward along the slide groove 306, thereby causing the second end of the lock tongue 309 to move upward to complete the unlocking action. In this process, the movement directions of the button 312 and the lock tongue 309 are parallel. Further, the first end and the second end of the seesaw 305 are both arc-shaped. This lock structure 300 design breaks through the application scenario limitations of traditional locks, and cleverly uses the lever principle to achieve motion control of the lock structure 300. The conductive contact surfaces at both ends of the rocker 305 adopt an arc-shaped structure, which makes the button 312 feel smooth and free of jamming, enhancing the user experience.
