[0033] As shown in Figures 1 to 6 The utility model provides a power supply device based on page turning to realize switch, its structure mainly includes casing assembly 10, battery compartment 111, plug slot 113, page turning linkage pull piece 13, elastic contact piece 20, conductive assembly, conductive connection end assembly and positioning assembly.

[0034] The casing assembly 10 is composed of the base 11 and the upper cover 12, and the two are fixed and protected by fitting arrangement to ensure the internal components. The base 11 and the upper cover 12 can be made of plastic, metal or other suitable materials to ensure the firmness and durability of the device.

[0035] The battery compartment 111 is arranged inside the base 11 and contains a plurality of battery slots 112 for placing batteries 30. The battery slots 112 are designed to fit the size of different models of batteries 30. In this embodiment, the batteries 30 are all button batteries, so the battery slots 112 are all designed as circular battery slots.

[0036] The plug slot 113 is located in the base 11 and is used to install and guide the sliding of the page turning linkage pull piece 13. The plug slot 113 and the corresponding part of the upper cover 12 are provided with a plurality of support blocks 114 evenly spaced, and the page turning linkage pull piece 13 slides on the support blocks 114, which reduces the contact area and ensures smooth sliding of the pull piece, while avoiding excessive friction. An avoidance opening is formed on the base 11, and after the base 11 and the upper cover 12 are installed by buckling, the avoidance opening and the plug slot 113 form a sliding channel for the page turning linkage pull piece 13.

[0037] The page-turning linkage pull-tab 13 is slidingly arranged in the plug slot 113. In the embodiment, one end of the page-turning linkage pull-tab 13 is connected with the movable page 41, and the base 11 is connected with the fixed page 42. When the movable page 41 is turned relative to the fixed page 42, the page-turning linkage pull-tab 13 slides in the plug slot 113.

[0038] It should be noted that the movable page 41 and the fixed page 42 in the embodiment respectively refer to the page-turning part and the non-page-turning part of the sound-emitting greeting card, sound-emitting book, sound-emitting electronic product and the like.

[0039] The elastic contact tab 20 comprises a fixed segment 21 and an elastic contact bending segment 22. The fixed segment 21 is arranged between one of the battery slots 112 and the plug slot 113, and is used to fix the position of the elastic contact tab 20. The elastic contact bending segment 22 abuts against the page-turning linkage pull-tab 13. When the page-turning linkage pull-tab 13 slides, the elastic contact bending segment 22 is deformed under pressure, and finally forms contact with the battery 30 in the battery slot 112, thereby establishing a circuit connection.

[0040] Specifically, the battery slot 112 at the head of the battery sequence and the plug slot 113 are mutually penetrated, and a mounting space is constructed between the two. A hemispherical assembly interference bump 24 is designed on the fixed segment 21 of the elastic contact tab 20. The fixed segment 21 is stably embedded in the mounting space, and the assembly locking bump 24 effectively prevents the fixed segment 21 from being accidentally detached. The movable end of the elastic contact bending segment 22 is clamped on the wall of the battery compartment 111. At this time, the body of the elastic contact bending segment 22 is in a bent state under no external force, and is bent into the plug slot 113, and abuts against the page-turning linkage pull-tab 13.

[0041] Preferably, an arc-shaped slot is opened on the page-turning linkage pull-tab 13. The elastic contact bending segment 22 of the elastic contact tab 20 abuts against the arc-shaped slot. When the page-turning linkage pull-tab 13 slides, the elastic contact bending segment 22 is separated from the arc-shaped slot, and is deformed by being pressed by the page-turning linkage pull-tab 13, and then slides to contact the battery 30 in the battery slot 112.

[0042] More preferably, the page-turning linkage pull-tab 13 is provided with a bendable indentation line 18. The pre-provided bendable indentation line 18 helps the page-turning linkage pull-tab 13 to be more smoothly bent during the page-turning process.

[0043] The conductive assembly includes a clamping block 15 and a connecting spring 16. The clamping block 15 is arranged between two adjacent battery grooves 112 and is used to fix the position of the connecting spring 16. The connecting spring 16 includes a clamping portion 161 and a bridging portion 162. The clamping block 15 is provided with a clamping hole, and the clamping portion 161 is clamped in the clamping hole to fix the connecting spring 16. The bridging portion 162 is symmetrically arranged on both sides of the clamping portion 161 and extends into the battery groove 112 to ensure the conductive connection of the two adjacent batteries 30.

[0044] The conductive connecting end assembly includes a first spring end 14 and a second spring end 23. The first spring end 14 is arranged at the bottom of the battery groove 112 at the end of the battery 30 sequence and is convenient for connecting with the battery 30 in the battery groove 112. The second spring end 23 is arranged on the elastic contact piece 20. The first spring end 14 and the second spring end 23 are used to connect with the external circuit. When the elastic contact piece 20 is deformed by the turning page linkage pull piece 13 and contacts the battery 30, a conductive loop is formed through the first spring end 14, the battery 30, and the second spring end 23 to realize the switching function. In this embodiment, the second spring end 23 is designed in one piece with the elastic contact piece 20. In this embodiment, the first spring end 14 includes a conductive contact section 141, a mounting section 142, and a welding section 143. The conductive contact section 141 is mounted at the bottom of the battery groove 112 at the end of the battery 30 sequence and is conductive with the battery 30. A mounting fixing hole 144 is pre-set on the mounting section 142 to facilitate mounting. A wire welding hole 145 is opened on the welding section 143, and the second spring end 23 is also provided with a wire welding hole 145. Through the wire welding holes 145 on the first spring end 14 and the second spring end 23, the first spring end 14 and the second spring end 23 can be conveniently welded with the wires of the external circuit, thereby completing the conduction work of the entire circuit.

[0045] The positioning assembly includes a plurality of positioning rods 116 and a plurality of positioning blocks 122 corresponding to the positioning rods 116. The positioning rods 116 are arranged on the base 11, and the positioning blocks 122 are arranged on the upper cover 12. The positioning blocks 122 are provided with positioning holes corresponding to the positioning rods 116, which are used to ensure that the base 11 and the upper cover 12 of the shell assembly 10 can be accurately positioned and fixed together during assembly. In this embodiment, the first spring end 14 can be fixed in the base 11 by cooperating with the mounting fixing hole.

[0046] In addition, a plurality of protrusions 115 can be arranged on the base 11, and the upper cover 12 is provided with a plurality of grooves 121 corresponding to the protrusions 115. The protrusions 115 and the grooves 121 can be matched with each other during assembly, further improving the stability and sealing performance of the shell assembly 10.

[0047] The base 11 is provided with a wire hole 17, which is used for connecting the connecting wire of the external circuit with the first elastic sheet end 14 and the second elastic sheet end 23 in the base 11, so as to supply power to the external circuit.

[0048] The specific implementation steps are as follows:

[0049] The base of the shell assembly of the power supply device is fixed on the fixed page of the sound-producing product. This is usually done through adhesives, screws, or other fastening methods, ensuring that the base is stable and not easily detached.

[0050] One end of the page-turning linkage pull tab is connected to the movable page (i.e., the part that turns) of the sound-producing product. This can be achieved through adhesives, riveting, screws, or other mechanical connection methods, ensuring that the pull tab can slide smoothly when turning the page.

[0051] Before turning the page, the page-turning linkage pull tab is in the initial position, and the elastic contact bend of the elastic contact sheet is in abutment with the arc-shaped slot of the page-turning linkage pull tab, but does not form contact with the battery, at which time the circuit is in an open state.

[0052] When the user turns the page, the movable page drives the page-turning linkage pull tab to slide in the tab slot. Because the pull tab has an arc-shaped slot, the elastic contact bend of the elastic contact sheet is disengaged from the arc-shaped slot and is deformed by being pressed by the pull tab.

[0053] After the elastic contact bend of the elastic contact sheet is deformed, it slides into the battery slot and forms contact with the battery, thereby establishing a circuit connection. At this time, through the conductive assembly and the conductive connection end assembly, current flows from the battery through the entire circuit and ultimately reaches the external circuit (such as the speaker of the sound-producing device).

[0054] When the circuit is closed, the external circuit (such as the speaker of the sound-producing device) obtains electrical energy and begins to work, emitting sound. The content and duration of the sound are determined by the design of the external circuit.

[0055] In summary, the power supply device based on page turning to realize switching provided by the present application achieves the automatic power supply function of the sound-producing product during the page turning process through ingenious structural design and working principle. This not only improves the interest and interactivity of the product, but also brings users a more convenient and comfortable user experience.

[0056] The above embodiments only exemplarily illustrate the principle and effect of the present application, and are not used to limit the present application. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of the present application. Therefore, all equivalent modifications or changes completed by those skilled in the art without departing from the spirit and technical thought disclosed by the present application should be covered by the claims of the present application.
