Technical Field
[0001] This utility model relates to the field of electric heating blanket technology, and in particular to a conductive structure for splicing electric heating blankets. Background Technology
[0002] Currently, most electric blankets on the market have a single, fixed structure with limited functionality, making them unsuitable for flexible adjustments based on actual usage scenarios. When users need to expand or shrink the area of the electric blanket to accommodate different sized beds, sofas, or other furniture, existing electric blankets struggle to meet this requirement. While some modular electric blanket designs exist, they suffer from numerous problems in circuit connections. For example, switching circuit connections during assembly and disassembly is not convenient and safe, easily leading to short circuits and open circuits, which not only affect the user experience but also pose certain safety hazards. Therefore, there is an urgent need to design a new type of modular electric blanket structure to solve these problems.
[0003] Therefore, the existing technology of electric blankets needs further improvement. Utility Model Content

Through ingenious circuit design and structural layout, when the electric heating blanket is disassembled, the two ends of the internal heating wire are electrically connected to the positive and negative terminals through a connecting circuit, forming a series connection. When splicing, the connecting circuit at the corresponding position is disconnected, so that the heating wires of the two electric heating blankets are connected in series, thereby achieving stable and safe operation of the electric heating blanket under different conditions and meeting the diverse usage needs of users.
[0005] To achieve the above objectives, this utility model adopts the following solution: a conductive structure for splicing electric heating blankets, comprising multiple electric heating blanket assemblies, wherein positive and negative conductive circuits are spaced apart vertically on each electric heating blanket assembly, a heating wire is disposed within each electric heating blanket assembly, and a connecting circuit is also included.

[0007] Furthermore, the heating wire is arranged in a wavy shape on the surface of the base layer, and the heating wire is made of carbon fiber material.
[0008] Furthermore, the splicing conductive pin assembly includes two conductive positioning rods spaced vertically on one side of the base layer;
[0009] The splicing conductive socket assembly includes two positioning holes spaced apart vertically on the other side of the base layer.
[0010] Furthermore, the circuit switching assembly includes a conductive rotating shaft structure disposed within the positioning hole. The conductive rotating shaft structure is provided with a conductive fan-shaped rotating block. The two planes of the conductive fan-shaped rotating block are respectively provided with a first contact surface and a second contact surface. A telescopic conductive rod assembly is disposed outside the positioning hole. The conductive positioning rod can be electrically connected to a corresponding second contact surface. A coil spring structure for controlling the conductive rotating shaft structure to perform reset rotation is disposed within the positioning hole.
[0011] Furthermore, the telescopic conductive rod assembly includes a transverse guide hole disposed outside the positioning hole, a telescopic conductive rod that can be electrically connected to the first contact surface is movably disposed in the transverse guide hole, and a spring structure for keeping the telescopic conductive rod pressed inward is disposed between the telescopic conductive rod and the transverse guide hole.

[0013] The connection circuit is electrically connected to the upper and lower telescopic conductive rods.

[0015] This invention addresses the shortcomings of existing electric blanket technology. Through its structural design, it offers the following advantages: flexible splicing and circuit switching. It enables flexible splicing of electric blankets. Through a unique circuit switching component, during disassembly, the heating wire is connected in series with the positive and negative terminals via a connecting circuit, ensuring the normal operation of a single electric blanket assembly. During splicing, the connecting circuit is automatically disconnected, allowing the heating wires of adjacent electric blanket assemblies to be connected in series, meeting the needs of large-area heating. The circuit connection is stable and reliable, effectively avoiding short circuits and open circuits, and automatically achieving safe circuit switching, reducing safety hazards and ensuring user safety. The design of the splicing conductive pin assembly and the splicing conductive socket assembly makes splicing the electric blanket simple and convenient. Users can easily complete splicing and disassembly operations without professional knowledge, improving ease of use. The overall structure is compact and reasonable, with close cooperation between components, ensuring the stability of the circuit connection without affecting the softness and comfort of the electric blanket, thus enhancing the user experience.

[0022] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figures 1-6 This utility model provides a conductive structure for splicing electric heating blankets, including multiple electric heating blanket assemblies 1. Each electric heating blanket assembly 1 is provided with a positive conductive circuit 2 and a negative conductive circuit 3 spaced vertically. Each electric heating blanket assembly 1 contains a heating wire 4 and a connecting circuit 5. Each electric heating blanket assembly 1 has a splicing conductive pin assembly 6 and a splicing conductive socket assembly 7 on both sides. The splicing conductive socket assembly 7 contains a circuit switching assembly 8. One end of the heating wire 4 is electrically connected to the positive conductive circuit 2, and the other end is electrically connected to the circuit switching assembly 8. The circuit switching assembly 8 is connected to one end of the connecting circuit 5, and the other end of the connecting circuit 5 is connected to the negative conductive circuit 3.
[0024] In the split state: each electric blanket component is independent. The conductive fan-shaped rotating block in the circuit switching component is in the initial position. One end of the heating wire is connected to the positive conductive circuit 2, and the other end is connected to the negative conductive circuit 3 through the first contact surface 803, the telescopic conductive rod 8052, and the connecting circuit 5, forming a series connection, so that the heating wire 4 can heat up and work.
[0025] In the splicing state: the conductive positioning rod 601 of one component is inserted into the positioning hole 701 of another component. The conductive positioning rod 601 presses against the second contact surface 804, causing the conductive fan-shaped rotating block 802 to rotate 90°, so that the second contact surface 804 and the conductive positioning rod 601 make parallel contact to achieve electrical connection. At the same time, the first contact surface 803 disengages from the telescopic conductive rod 8052 and disconnects from the connection circuit 5, so that the heating wires 4 of adjacent components are connected in series through the conductive positioning rod 601 and the second contact surface 804 to meet the large-area heating requirements.
[0026] Disassembly and restoration: Pull out the conductive positioning rod 601, the coil spring structure 806 resets the conductive fan-shaped rotating block 802, the first contact surface 803 re-contacts the telescopic conductive rod 8052, and each component returns to the series circuit state of independent operation.
[0027] The electric heating blanket assembly 1 of this utility model includes a base layer 101, and a blanket 102 is wrapped around the base layer 101.
[0028] The heating wire 4 of this invention is arranged in a wavy shape on the surface of the base layer 101, and the heating wire 4 is made of carbon fiber material.
[0029] The splicing conductive pin assembly 6 of this utility model includes two conductive positioning rods 601 that are spaced apart vertically on one side of the base layer 101;
[0030] The splicing conductive socket assembly 7 includes two positioning holes 701 that are spaced apart vertically on the other side of the base layer 101.

The conductive positioning rod 601 can be electrically connected to a corresponding second contact surface 804. A coil spring structure 806 for controlling the reset rotation of the conductive rotating shaft structure 801 is disposed in the positioning hole 701. When the conductive positioning rod 601 is inserted into the corresponding positioning hole 701, it will press the second contact surface 804 and cause the conductive fan-shaped rotating block 802 to rotate 90°, so that the second contact surface 804, which was originally perpendicular to the conductive positioning rod 601, is parallel to the conductive positioning rod 601 and in contact with it. At this time, the first contact surface 803, which has rotated 90°, disengages from the contact of the telescopic conductive rod 8052 and completes the disconnection.
[0032] The telescopic conductive rod assembly 805 of this utility model includes a transverse guide hole 8051 disposed outside the positioning hole 701, a telescopic conductive rod 8052 that can be electrically connected to the first contact surface 803 is movably disposed in the transverse guide hole 8051, and a spring structure 8053 for keeping the telescopic conductive rod 8052 pressed inward is disposed between the telescopic conductive rod 8052 and the transverse guide hole 8051.
