[0020] The following description, in conjunction with the accompanying drawings, details specific embodiments of the present invention. The detailed description and drawings below are provided to exemplify the principles of the invention; however, the invention is not limited to the described preferred embodiments, and the scope of protection of the invention is defined by the claims.

[0021] like Figure 1-3 As shown, this embodiment of the invention provides a heating belt. The heating belt includes a heating belt body and a heating component. The heating component is disposed on the heating belt body. The heating component can heat the heating belt body, thereby forming a heating belt with heating function.

[0022] The heating band body comprises connected single-layer sections 110 and double-layer sections 120, with the double-layer section 120 having a sandwich 121. The single-layer section 110 and the double-layer section are two parts along the length of the heating band body. The majority of the heating band body is composed of single-layer sections 110, and a smaller portion is composed of double-layer sections 120. The double-layer section 120 primarily provides location and shielding for the connection of the heating wire 210.

[0023] The heating assembly includes a heating wire 210 and a power source. The power source provides energy to the heating wire 210, which heats the main body of the heating band. The power source is located at the end of the single-layer segment 110 away from the double-layer segment 120. The heating wire 210 is embedded in the single-layer segment 110, with one end connected to the power source and the other end connected within the interlayer 121 to form a closed loop.

[0024] The heating wire 210 is embedded in the single-layer segment 110, that is, the heating wire 210 is wrapped inside the single-layer segment 110, forming an integral structure with the single-layer segment 110, and is not exposed on the outer surface of the single-layer segment 110. The heating wire 210 can be woven inside the single-layer segment 110.

[0025] In an embodiment of the present invention, the double-layer segment 120 includes an upper layer 122 and a lower layer 123, which are separated and form an interlayer 121 between them. Within the interlayer 121, heating wires 210 are welded together to form a closed circuit. The separation of the upper layer 122 and the lower layer 123 provides an operating space that can provide position and shielding for the connection of the heating wires 210.

[0026] The upper layer 122 and the lower layer 123 are two opposing layers, without any restriction on their vertical position.

[0027] In an embodiment of the present invention, an adhesive film is further provided within the interlayer 121. The adhesive film at least covers the welding points 211 of the heating wires 210, and the adhesive film bonds the welding points 211 to the upper layer 122 or the lower layer 123. After the heating wires 210 are welded together, they have welding points 211. These welding points 211 are the connection points where the heating wires 210 are connected to form a closed circuit. After the adhesive film covers the welding points 211, it bonds the welding points 211 to the upper layer 122 or the lower layer 123, thus fixing the welding points 211 to the upper layer 122 or the lower layer 123. In this way, even if the double-layer segment 120 has open and close welding points 211, they will not be exposed. Furthermore, the adhesive film covering the welding points 211 is an insulating adhesive film. The adhesive film also serves as an insulating and isolating agent.

[0028] In an embodiment of the present invention, the adhesive film bonds the upper layer 122 and the lower layer 123 together. This prevents the interlayer 121 of the double-layer segment 120 from easily opening or closing. The adhesive film used here can be the same as the adhesive film covering the welding point 211. That is, after the adhesive film covers the welding point 211, it bonds the welding point 211 to one of the upper layer 122 and the lower layer 123. Then, the other side of the adhesive film bonds the other layer of the upper layer 122 and the lower layer 123 together. The adhesive film used here is a double-sided adhesive film.

[0029] The adhesive film covering the welding point 211 and the adhesive film bonding the upper layer 122 and the lower layer 123 together can be different adhesive films. That is, after the adhesive film covers the welding point 211, it bonds the welding point 211 to the upper layer 122 or the lower layer 123. Then, another adhesive film is used to bond the upper layer 122 and the lower layer 123 together.

[0030] In an embodiment of the present invention, the power supply includes a PCB board 220 (printed circuit board). The PCB board 220 is located on the surface of the single-layer segment 110, and the end of the heating wire 210 extends out of the single-layer segment 110 and is connected to the PCB board 220. The PCB board 220 controls the operation of the heating wire 210, thereby controlling the heating function of the heating band.

[0031] The heating band also includes a cover assembly. The cover assembly includes an upper cover 410 and a lower cover 420. The upper cover 410 is located on one side of the single-layer segment 110 and covers the PCB board 220, while the lower cover 420 is located on the other side of the single-layer segment 110. The upper cover 410 and the lower cover 420 are connected and fix the PCB board 220 to the single-layer segment 110. On the one hand, the upper cover 410 and the lower cover 420 can cover the PCB board 220, thereby protecting the PCB board 220; on the other hand, the upper cover 410 and the lower cover 420 can also fix the PCB board 220 to the heating band body.

[0032] PCB board 220 is located on one side of single-layer section 110, upper cover plate 410 covers PCB board 220, and lower cover plate 420 is located on the other side of single-layer section 110. The four are then connected together by screws or snap-fit ​​posts. PCB board 220 is then connected to other power supply or control devices via control line 230.

[0033] The upper cover plate 410 and the lower cover plate 420 are opposite each other, and there is no limitation on the upper and lower positions of the cover plates.

[0034] In embodiments of the present invention, the heating belt body includes a first layer 510, a second layer 520, and a connecting yarn 530. In a single-layer section 110, the connecting yarn 530 weaves the first layer 510 and the second layer 520 together to form the single-layer section 110. In a double-layer section 120, the connecting yarn 530 is woven together only with the first layer 510 or the second layer 520, and the first layer 510 and the second layer 520 are separated to form the double-layer section 120.

[0035] like Figure 2 As shown, the joining yarn 530 weaves the first layer 510 and the second layer 520 together, thus weaving the first layer 510 and the second layer 520 into one layer, forming the single-layer segment 110 described above. Figure 3 As shown, the knotting yarn 530 is woven together only with the first layer 510 or the second layer 520, so that the first layer 510 and the second layer 520 are separated, and there is an openable sandwich layer 121 between the first layer 510 and the second layer 520, thereby forming the double-layer segment 120 mentioned above.

[0036] The first layer 510, the second layer 520, and the connecting yarn 530 structurally divide the heating belt body into several parts. Furthermore, the different connection methods of the first layer 510, the second layer 520, and the connecting yarn 530 form the single-layer segment 110 and the double-layer segment 120 mentioned earlier. The upper layer 122 and the lower layer 123 mentioned earlier are the parts of the double-layer segment 120 corresponding to the first layer 510 and the second layer 520, respectively.

[0037] In an embodiment of the invention, in the single-layer segment 110, the heating wire 210 is woven between the first layer 510 and the second layer 520, thereby embedding it inside the single-layer segment 110. In the double-layer segment 120, the heating wire 210 is separated from the first layer 510 and the second layer 520. The heating wire 210 is welded together in the double-layer segment 120.

[0038] like Figure 2 and Figure 3 As shown, the first layer 510 and the second layer 520 have the same structure, both woven from warp and weft yarns. The heating wire 210 does not interweave with the warp and weft yarns between the first layer 510 and the second layer 520, thus being hidden between the first layer 510 and the second layer 520.

[0039] In embodiments of the present invention, the heating assembly includes multiple heating wires 210, which are spaced apart on the heating belt body. This ensures that the heating belt body is heated uniformly across its width, enhancing the user experience.

[0040] In embodiments of the present invention, the heating belt body is an elastic heating belt body.

[0041] In the embodiments of the present invention, the heating belt can be a seat belt, or of course, it can be used for other seat belts that require heating.

[0042] As mentioned above, although exemplary embodiments of the present invention have been described with reference to the accompanying drawings, the present invention is not limited to the specific embodiments described above, and the scope of protection of the present invention should be defined by the claims and their equivalents.
