[0002] With the increasing prevalence of electronic devices and global travel, users often need to use chargers in different countries or regions.

[0003] Traditional chargers typically have fixed plugs that are incompatible with different socket standards. Users often need to carry multiple chargers when traveling internationally, causing inconvenience and increasing costs. Some existing chargers with replaceable plugs have the following problems:

[0004] Unstable connection: The connection between the plug and the charger body is unreliable and prone to loosening, leading to poor contact;

[0005] Complex structure: The disassembly and assembly process is cumbersome and requires the use of tools or multiple steps to complete;

[0006] Therefore, it is necessary to design a modular charger with a simple structure and reliable connection to address the shortcomings of existing technologies. Summary of the Invention

[0007] The purpose of this invention is to provide a charger with modular assembly and disassembly functions, achieving the effects of convenient assembly and disassembly, reliable connection, and simple structure.

[0008] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a charger with modular assembly and disassembly function, comprising a charger body and a detachable plug module;

[0009] The charger body has a recessed notch at one corner for installing a plug module. A conductive contact is disposed within the notch. A power conversion module is disposed inside the charger body. The power conversion module is electrically connected to the conductive contact and the charger output interface, and is used to convert the electrical energy input through the conductive contact and output it through the charger output interface.

[0010] The plug module has a pin on one side and a resilient contact on the other side corresponding to the conductive contact piece. The plug module has a conductive line inside, one end of which is electrically connected to the pin and the other end of which is electrically connected to the resilient contact, for transmitting the electrical energy obtained by the pin to the resilient contact.

[0011] A positioning mechanism and a limiting mechanism are configured between the plug module and the charger body.

[0012] As a preferred technical solution of this utility model, the disassembly notch includes a first notch plate and a second notch plate; the outer shell of the charger body also includes a top plate, a front plate, a rear plate, a left plate, a right plate, and a bottom plate connected accordingly.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Therefore, the following detailed description of the embodiments of this utility model provided in the drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0026] As shown in Figure 1, the purpose of this utility model is to provide a charger with modular assembly and disassembly function, which adapts to different socket standards through a detachable plug module 2, and ensures connection stability and safety through optimized positioning, limiting and conductive structure.

[0027] The charger includes a charger body 1 and a detachable plug module 2. A recessed mounting notch is provided at one corner of the charger body 1 for installing the plug module 2. The mounting notch is formed by a first notch plate 6 and a second notch plate 7, and is fixedly connected to the top plate 8, front plate 21, rear plate 22, left plate 9, right plate 10 and bottom plate 11 of the main body shell to form a stable installation space.

[0028] As shown in Figure 2, to achieve stable electrical conductivity between the plug module 2 and the charger body 1, a conductive contact 3 is provided on the first notch plate 6 of the charger body 1. The internal power conversion module is electrically connected to the conductive contact 3 and the charger output interface 23 through a printed circuit board. The output interface 23 is located on the bottom plate 11 of the casing, so that the electrical energy obtained by the plug module 2 is transmitted to the power conversion module through the elastic contact 5 and the conductive contact 3, and finally stably output to the device, solving the problem of charging interruption caused by unstable connection of existing chargers. A pin 4 is provided on one side of the plug module 2, and an elastic contact 5 is provided on the other side. The pin 4 and the elastic contact 5 are connected through internal conductive lines. The elastic contact 5 consists of an arc-shaped contact head 19, a support spring 20, and an i-shaped support frame 18. The two ends of the i-shaped support frame 18 are fastened to the inside of the housing of the plug module 2 to form an enclosed structure. The support spring 20 provides continuous pressure to the contact head 19 within the enclosed structure, ensuring that the contact head 19 is in close contact with the conductive contact piece 3 and achieving stable conductivity. Compared with the traditional plug-in connection, it ensures stable conductivity even under vibration and shaking conditions, effectively solving the problems of easy loosening and poor contact of existing replaceable plugs.

[0029] The positioning mechanism uses the raised positioning strip 12 on the top surface of the second notch plate 7 to cooperate with the positioning groove 13 at the bottom of the plug module 2 to ensure accurate alignment during installation. The rotating plate 15 of the limiting mechanism is sleeved on the positioning rod 14 through the rotating hole. When the rotating plate 15 rotates to the top of the disassembly notch, it restricts the plug module 2 from coming out, and the anti-dislodgement limiting block 16 at the top of the positioning rod 14 prevents the rotating plate 15 from falling off.

[0030] As shown in Figure 3, it should be noted that there are no disassembly notches on the front panel 21 and the rear panel 22 of the shell. Only the top panel 8 and the right panel 10 of the shell have disassembly notches. Therefore, there is only one installation direction when installing the plug module 2. After installation, the plug module 2 will not come out when the rotating plate 15 is on top of the plug module 2.

[0031] The power conversion module integrates overvoltage protection circuitry, overcurrent protection circuitry, and temperature monitoring circuitry. When abnormal voltage, current, or temperature is detected, the protection circuitry automatically cuts off the output to prevent damage to equipment or safety accidents.

[0032] It should be noted that the power conversion module, overvoltage protection circuit, overcurrent protection circuit, and temperature monitoring circuit of this utility model all adopt existing mature technologies. The power conversion module converts AC power into stable DC power output through a rectifier and filter circuit, a DC-DC conversion circuit, and a control circuit. The relevant circuits and chip selections are widely used in existing chargers.

[0033] Overvoltage and overcurrent protection circuits utilize devices such as voltage comparators and current sampling resistors to monitor voltage and current anomalies and cut off the output accordingly. The temperature monitoring circuit collects temperature data through a thermistor and triggers power-off when the temperature exceeds the limit. These protection circuits are mature applications in the field of electronic equipment, and this utility model only integrates them for compatibility without making any creative improvements. By integrating existing circuit technology with the detachable plug module 2 structure, both functional convenience and circuit safety are balanced.

[0034] In practical applications, align the positioning groove 13 at the bottom of the plug module 2 with the positioning strip on the second notch plate 7, and slide it vertically into the disassembly notch until the elastic contact 5 is in complete contact with the conductive contact 3. Rotate the rotating plate 15 on the positioning rod 14 to cover the top of the plug module 2, completing the vertical limitation, while the horizontal limitation is achieved by the front shell plate 21 and the rear shell plate 22, making the limitation state more stable. At this time, the spring is in a compressed state, providing contact pressure and ensuring conductive stability.

[0035] Rotate the rotating plate 15 in the opposite direction to release the restriction on the plug module 2, and pull the plug module 2 upward to disengage it from the disassembly notch. During disassembly, the spring of the elastic contact 5 gradually returns to its original state, and the contact head 19 retracts into the contact opening 17.

[0036] When the charger output interface 23 is short-circuited, the overcurrent protection circuit can cut off the output; if the temperature is detected to exceed the set threshold, the temperature monitoring circuit will trigger power-off; the overvoltage protection circuit will ensure that the output voltage is stable within the set range.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. For those skilled in the art, the present utility model can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
