[0020] The specific embodiments according to the present application will be described below with reference to the accompanying drawings. The following detailed description and drawings are used to illustrate the principles of the present application, and the present application is not limited to the preferred embodiments described, and the protection scope of the present application is defined by the claims.

[0021] As shown in FIGS. 1-3, an embodiment of the present application provides a heating belt. The heating belt comprises a heating belt body and a heating assembly. The heating assembly is arranged on the heating belt body. The heating assembly can heat the heating belt body, thereby forming a heating belt with heating function.

[0022] The heating belt body comprises a single layer section 110 and a double layer section 120 connected together, and the double layer section 120 has a sandwich layer 121. The single layer section 110 and the double layer section 120 are two parts in the length direction of the heating belt body. Most of the heating belt body is the single layer section 110, and a small part is the double layer section 120. The double layer section 120 mainly provides a position and shielding for the connection of the heating wire 210.

[0023] The heating assembly comprises a heating wire 210 and a power supply. The power supply provides energy for the heating wire 210, and the heating wire 210 heats the heating belt body. The power supply is located at one end of the single-layer section 110 away from the double-layer section 120. The heating wire 210 is embedded in the single-layer section 110, and one end of the heating wire 210 is connected to the power supply, and the other end is connected to form a closed loop in the interlayer 121.

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

[0025] In the embodiment of the present application, the double-layer section 120 comprises an upper layer 122 and a lower layer 123, the upper layer 122 and the lower layer 123 are separated, and the interlayer 121 is formed between the upper layer 122 and the lower layer 123, and the heating wire 210 is welded to form a closed loop in the interlayer 121. The upper layer 122 and the lower layer 123 are separated, and there is an operation space between the upper layer 122 and the lower layer 123, which can provide a position and shielding for the connection of the heating wire 210.

[0026] Here, the upper layer 122 and the lower layer 123 are two opposite layers without the limitation of up and down positions.

[0027] In the embodiment of the present application, the interlayer 121 is further provided with a film, and the film covers at least the welding point 211 of the heating wire 210, and the film bonds the welding point 211 to the upper layer 122 or the lower layer 123. After the welding connection of the heating wire 210, the welding point 211 is formed. The welding point 211 is the connection point of the closed loop of the heating wire 210. After the film covers the welding point 211, the welding point 211 is bonded to the upper layer 122 or the lower layer 123. The welding point 211 is fixed on the upper layer 122 or the lower layer 123. In this way, the double-layer section 120 will not be exposed even if the welding point 211 is opened. Moreover, the film covering the welding point 211 is an insulating film. The film can also play the role of insulation and isolation.

[0028] In the embodiment of the present application, the film bonds the upper layer 122 and the lower layer 123 together. In this way, the interlayer 121 of the double-layer section 120 will not be easily opened. Here, the film can be the same film as the film covering the welding point 211. That is, after the film covers the welding point 211, the welding point 211 is bonded to one of the upper layer 122 and the lower layer 123, and then the other side of the film bonds the other of the upper layer 122 and the lower layer 123 together. Here, the film is a double-sided film.

[0029] The adhesive film covering the welding points 211 and the adhesive film bonding the upper layer 122 and the lower layer 123 together can also be different adhesive films. That is, the adhesive film covering the welding points 211 bonds the welding points 211 to the upper layer 122 or the lower layer 123. Another adhesive film is used to bond the upper layer 122 and the lower layer 123 together.

[0030] In the embodiment of the present application, the power supply includes a PCB board 220 (printed circuit board). The PCB board 220 is located on the surface of the single layer section 110, and the ends of the heating wires 210 extending out of the single layer section 110 are connected to the PCB board 220. The PCB board 220 controls the operation of the heating wires 210, thereby controlling the heating function of the heating belt.

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

[0032] The PCB board 220 is arranged on one side of the single layer section 110, the upper cover plate 410 covers the PCB board 220, and the lower cover plate 420 is arranged on the other side of the single layer section 110, and then the four are connected together by screws or clamping columns. The PCB board 220 is further connected to other power supply devices or control devices through the control lines 230.

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

[0034] In the embodiment of the present application, the heating belt body includes a first layer 510, a second layer 520, and a binding yarn 530. In the single layer section 110, the binding yarn 530 weaves the first layer 510 and the second layer 520 together to form the single layer section 110. In the double layer section 120, the binding yarn 530 only weaves 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] As shown in FIG. 2, the binding yarn 530 weaves the first layer 510 and the second layer 520 together, so that the first layer 510 and the second layer 520 are woven into one layer, forming the single-layer section 110 described above. As shown in FIG. 3, the binding yarn 530 only weaves with the first layer 510 or the second layer 520, so that the first layer 510 and the second layer 520 are separated, and the first layer 510 and the second layer 520 form the openable and closable interlayer 121, thereby forming the double-layer section 120 described above.

[0036] The first layer 510, the second layer 520 and the binding yarn 530 here are several parts divided from the structure of the heating belt body. Different connections of the first layer 510, the second layer 520 and the binding yarn 530 form the single-layer section 110 and the double-layer section 120 described above. The upper layer 122 and the lower layer 123 described above are the parts of the first layer 510 and the second layer 520 corresponding to the double-layer section 120, respectively.

[0037] In the embodiment of the present application, in the single-layer section 110, the heating wire 210 is woven between the first layer 510 and the second layer 520, thereby being embedded in the inside of the single-layer section 110. In the double-layer section 120, the heating wire 210 is separated from the first layer 510 and the second layer 520. In the double-layer section 120, the welding connection of the heating wire 210 is achieved.

[0038] As shown in FIG. 2 and FIG. 3, the first layer 510 and the second layer 520 are both woven by warp yarns and weft yarns. The heating wire 210 is not interwoven with the warp yarns and the weft yarns between the first layer 510 and the second layer 520, thereby being hidden between the first layer 510 and the second layer 520.

[0039] In the embodiment of the present application, the heating assembly includes a plurality of heating wires 210, which are distributed on the heating belt body at intervals. This makes the heating belt body uniformly heated in width, thereby enhancing the user experience.
