This forces users to have multiple independent docks, increasing usage costs and space consumption. 2. Lack of modular design: Charging docks are mostly independent structures, lacking standardized connectors or splicing interfaces. This prevents the cascading expansion of multiple docks through physical connections, limiting the flexibility of application scenarios. These issues result in significant shortcomings in functionality, user experience, and expandability of existing charging docks. Utility Model Content

[0031] like Figures 1 to 5 As shown, a cascaded charging base includes a charging base 1 with a circuit board inside. The charging base 1 has several charging slots 11 spaced apart for charging target components. Each charging slot 11 has at least three shapes, each shape is used to stabilize the target component, and different target components have different shapes.

[0032] Conductive pins 2: Several conductive pins 2 can be detachably provided on the side wall of each of the charging bases 1 to connect two adjacent charging bases 1.

[0033] The charging base 1 of this solution can support the charging of the second target component 4 (handheld microphone), the third target component 5 (waist pack transmitter) and the first target component 3 (such as lithium battery, nickel-metal hydride battery). It is used in public places such as training rooms, conference rooms, banquet halls, and opera houses.

[0034] Specifically, the charging base 1 has a certain installation space inside, and the circuit board is set in this installation space. The circuit board is electrically connected to an external power supply or a built-in power supply. Each charging base 1 includes at least two charging slots 11, each supporting a first target component 3 (such as a battery), a second target component 4 (such as a handheld microphone), or a third target component 5 (a waist-pack transmitter). This structural design allows for simultaneous charging of two devices with a single base, and also enables dual-slot charging for multiple devices. For example, it can simultaneously charge two third target components 5, or simultaneously charge the second target component 4 and the third target component 5. In particular, several conductive pins 2 are provided on the left and right side walls of the charging base 1, allowing adjacent charging bases 1 to be connected and fixed together, achieving electrical cascading of multiple charging bases 1. Specifically, it supports cascading four charging bases 1. Users can increase or decrease the number of cascaded units as needed, such as setting two, three, or four. Thus, a single charging base 1 can support charging two devices, and four cascaded units can simultaneously charge eight devices, adapting to different usage scales / scenarios.

[0035] Furthermore, each of the charging slots 11 includes a first shape 111, a second shape 112 and a third shape 113, and the target component includes a first target component 3, a second target component 4) and a third target component 5. The first shape located at the upper end of the charging slot 11 is used to clamp the first target component 3, and the first shape 111 is provided with a conductive contact 1111 connected to the circuit board.

[0036] The second shape 112 extends through the charging slot 11 so that the second target component 4 can be inserted and locked in the second shape 112. The second shape 112 is provided with a TYPE-C charging terminal 1121 connected to the circuit board.

[0037] The top of the third shape 113 intersects with the first shape 111, and the upper end of the second shape 112 partially overlaps with the third shape 113. The third shape 113 is used to clamp the third target component 5. The third shape 113 is provided with the TYPE-C charging terminal 1121 connected to the circuit board.

[0038] Specifically, the first shape 111 is located at the top of the charging slot 11, and its shape matches that of the first target component 3 to fix the two ends of the first target component 3. Since the first shape 111 and the third shape 113 intersect, the interior of the first shape 111 is not a complete cylinder, but has a hollow structure in the middle. The second shape 112 is vertically arranged and extends through the entire charging slot 11, and its overall shape matches the outer contour of the second target component 4. The upper end of the second shape 112 partially overlaps with the middle part of the third shape 113. The third shape 113 is vertically arranged and extends from the middle of the charging slot 11 to the top, so that the third shape 113 intersects with the first shape 111. Typically, the first shape 111 and the third shape 113 intersect perpendicularly, and the overall shape of the third shape 113 matches the outer contour of the second target component 4.

[0039] Furthermore, the conductive pin 2 includes a mounting base 21, a connecting portion 22, a snap-fit ​​arm 23, and a conductive connector 24. The mounting base 21 is provided with the connecting portion 22, and the snap-fit ​​arm 23 is provided on both sides of the connecting portion 22. The width of the snap-fit ​​arm 23 gradually increases from the side closer to the connecting portion 22 to the side farther away from the connecting portion 22.

[0040] The side wall of the charging base 1 is provided with a plurality of slots 12. The two locking arms 23 are respectively locked into the slots 12 of two adjacent charging bases 1. The mounting base 21 is also provided with the conductive connector 24. The conductive connector 24 includes conductive posts 241, and the two conductive posts 241 are respectively located outside the two locking arms 23. The two conductive posts 241 are respectively connected to the circuit board of the corresponding charging base 1.

[0041] In this embodiment, as Figure 5 As shown, the conductive pin 2 mainly achieves the splicing and fixing between adjacent charging bases 1 through the cooperation of the connecting part 22 and the snap-fit ​​arm 23. Both the connecting part 22 and the snap-fit ​​arm 23 are set on the mounting base 21. Since the side wall of the charging base 1 has a slot 12 that fits with the snap-fit ​​arm 23, the two snap-fit ​​arms 23 on both sides of the connecting part 22 can clamp the two adjacent charging bases 1. The electrical cascading of the charging bases 1 is achieved through the conductive connector 24, which is also set on the mounting base 21. The conductive connector 24 includes two conductive posts 241 located on both sides of the snap-fit ​​arm 23. The two conductive posts 241 are respectively connected to the circuit boards in the two adjacent charging bases 1, thereby realizing the electrical cascading of the two adjacent charging bases 1.

[0042] Furthermore, the top of the slot 12 is provided with a circular protrusion 121, and the top of the snap-fit ​​arm 23 is provided with a corresponding recess 231. The protrusion 121 is used to snap into the recess 231 when the snap-fit ​​arm 23 is snapped into the slot 12.

[0043] In this embodiment, in order to allow the user to better confirm whether the conductive pin 2 is properly engaged, a circular protrusion 121 is provided at the top of the slot 12, and a recess 231 is provided at the top of the engagement arm 23. When the two charging bases 1 are put together and the conductive pin 2 is inserted, when the conductive pin 2 is properly engaged, the protrusion 121 in the slot 12 will engage in the recess 231 of the engagement arm 23. Typically, the thickness of the protrusion 121 gradually increases from the edge to the center, which makes it easier for the protrusion 121 to slide into and engage in the recess 231.

[0044] Furthermore, when the two latching arms 23 are respectively latched into the slots 12 of two adjacent charging bases 1, one side of the connecting part 22 is located in the slot 12 of one charging base 1, and the other side of the connecting part 22 is located in the slot 12 of the other charging base 1, so that the edges of the two adjacent charging bases 1 fit together.

[0045] In this embodiment, as Figure 5 As shown, in addition to the snap-fit ​​arm 23 snapping into the slot 12 of the charging base 1, the connecting part 22 also snaps into the slot 12. Specifically, half of the connecting part 22 is located in the slot 12 of one of the charging bases 1, and the other half is located in the slot 12 of the other charging base 1. In this way, the two charging bases 1 that are spliced ​​and fixed can fit tightly together, resulting in better overall integrity. Furthermore, after inserting the conductive pin 2 into the slot 12, the above-mentioned embedded design can eliminate the risk of accidental contact during use.

[0046] Furthermore, along the height direction of the connecting portion 22, a plurality of grooves 221 are provided at intervals on the connecting portion 22. In this way, when multiple grooves 221 are provided, the strength of the conductive pin 2 can be guaranteed, while the raw materials can be saved when manufacturing the conductive pin 2, and the resulting conductive pin 2 is lighter in weight.

[0047] Furthermore, the conductive connector 24 is a U-shaped copper pin. In actual production, a pin header socket is soldered onto the circuit board, and holes for inserting the conductive post 241 are provided on the charging base 1 at positions corresponding to the pin header socket. The mounting base 21, connecting part 22, and snap-fit ​​arm 23 of the conductive pin 2 are usually made of plastic. A U-shaped copper pin is integrally formed on the mounting base 21, which has the characteristics of high conductivity and low resistance, and is suitable for electrical cascading of multiple charging bases 1.

[0048] Furthermore, adjacent charging bases 1 are interconnected by at least two conductive pins 2. Conductive pins 2 are respectively provided at the front and rear positions on both sides of the charging base 1, and the two conductive pins 2 can achieve a stable fixation between adjacent charging bases 1. Of course, when splicing and fixing larger charging bases 1, three or four conductive pins 2 can also be used for fixation.

[0049] Furthermore, the front side of the charging base 1 is also provided with an OLED display screen 13, which is connected to the circuit board. Figures 1 to 4 As shown, the existing charging dock 1 only uses simple LED indicator lights to reflect the charging status, lacking an intuitive screen display, making it difficult for users to grasp accurate charging information in real time. Therefore, the charging dock 1 of this embodiment is also equipped with an OLED display screen 13, which allows users to easily obtain current charging information. For example, the OLED display screen 13 can display information such as charging progress, battery compartment, cascade icons, and network icons.

[0050] Furthermore, the charging base 1 is also provided with charging indicator lights 14. In this embodiment, each charging base 1 may also be provided with 6 charging indicator lights 14 at its upper end for charging contact indication and full charge display.

[0051] Furthermore, the first shape 111 includes at least two (battery) slots 1112. Each first shape 111 has two (battery) slots 1112, and each (battery) slot 1112 is provided with positive and negative springs connected to conductive contacts 1111, and then connected to the circuit board through the conductive contacts 1111.

[0052] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
