Description

Technical Field

[0001] The utility model relates to the technical field of automobile seat heating, in particular to an automobile seat heating structure. Background Art

[0002] Traditional vehicle seats are mostly heated by heating pads installed on the seats. Such heating pads usually use a heating pad body, a finished seat foam body and a seat cover for later assembly. After long-term use, the heating pads often have wrinkles, which will cause severe overheating of the seat surface and cause harm to the human body. In high-end models, the design of integrating the seat heating system with the seat structure has become a trend. By building the heating element into the seat foam manufacturing stage and using a special one-piece mold molding process, the heating pad is no longer an independent component added later, but is tightly integrated with the seat foam. This not only avoids the formation of wrinkles, but also makes the heating more uniform and improves durability.

[0003] Car seats are usually provided with multiple grooves, and the heating wires on the car seats have some bend angles of approximately 90 degrees when passing through these grooves. After long-term use, these heating wires with large bend angles are more likely to be damaged, making the heating function ineffective and even causing danger to the human body.

Heating structures connected in sequence are arranged on the heating zone one, the heating zone two and the heating zone three, and the heating structure includes a heating tube provided with a plurality of bending curves, the heating tube of the heating zone one is connected to the heating tube of the heating zone two through a bridge protection tube, the heating tube of the heating zone two is connected to the heating tube of the heating zone three through a bridge protection tube, a bridge hole is arranged below the groove on the back foam body of the car seat, a bridge protection tube is arranged in the bridge hole, and the heating tube passes through the bridge hole through the bridge protection tube.

[0006] Preferably, the heating tubes on heating zone 1, heating zone 2 and heating zone 3 are all embedded in the surface of the foam.

[0007] Preferably, the heating tube comprises an outer flame-retardant tube and an inner heating body, and the inner heating body is arranged inside the outer heating body.

[0008] Preferably, the outer flame-retardant tube is a plastic tube added with a bromine-based flame retardant, and a plurality of heat dissipation holes are evenly arranged on the outer flame-retardant tube.

[0009] Preferably, the inner layer heating body comprises a metal round tube, on which a heating wire is spirally wound.

[0010] Preferably, the bridge protection tube is a metal tube, the outer layer of the metal tube is provided with a rubber layer, and the inner layer of the metal tube is provided with a plastic tube added with a brominated flame retardant.

[0011] Preferably, both ends of the bridge protection tube are inserted into the fracture of the heating tube, and the heating wire passes through the bridge protection tube.

[0012] Preferably, the bends of the bridge protection tube are all obtuse angles.

[0013] Therefore, the utility model adopts the above-mentioned structure of the car seat heating structure, by arranging a bridge protection tube under the groove of the car seat foam body, the bending angle of the bridge protection tube is an obtuse angle, so that the heating wire can pass smoothly, which will not affect the use of the groove and can make the bending angle of the heating wire smooth, thereby increasing the service life of the heating wire; by arranging a bridge protection tube between the three heating zones, the heating wire can be smoothly transitioned to other heating zones, and the bridge protection tube can protect the heating wire; by spirally winding the heating wire on the metal round tube, the contact area between the heating wire and the car seat can be increased, thereby increasing thermal conductivity; by arranging multiple heat dissipation holes on the outer flame-retardant tube of the heating tube, the heat generated by the heating wire can be transferred out more quickly.

[0024] Example

[0025] like Figure 1 As shown, a car seat heating structure described in the utility model comprises a car seat 1, a heating zone 1 2 is arranged on the seat foam of the car seat 1, a heating zone 2 3 is arranged on the backrest foam of the car seat 1, a heating zone 3 4 is arranged on the headrest foam of the car seat 1, and heating structures connected in sequence are arranged on the heating zone 1 2, the heating zone 2 3, and the heating zone 3 4. The heating structure comprises a heating tube 5 provided with a plurality of bending curves, and the heating tubes 5 on the heating zone 1 2, the heating zone 2 3, and the heating zone 3 4 are all embedded in the surface of the foam body, so as to improve the comfort of the occupants sitting on the car seat 1.

[0026] like Figure 2As shown, the heating tube 5 includes an outer flame-retardant tube 7 and an inner heating body, and the inner heating body is arranged inside the outer heating body. The outer flame-retardant tube 7 is a plastic tube added with a bromine-based flame retardant, and a number of heat dissipation holes 8 are evenly arranged on the outer flame-retardant tube. The inner heating body includes a metal round tube 10, and a heating wire 9 is spirally wound on the metal round tube 10. By spirally winding the heating wire 9 on the metal round tube 10, the contact area between the heating wire 9 and the car seat 1 can be increased, thereby increasing heat conduction, and achieving faster heating and faster heating speed; by arranging multiple heat dissipation holes 8 on the outer flame-retardant tube 7 of the heating tube 5, the heat generated by the heating wire 9 can be transferred out more quickly, thereby increasing the heat dissipation effect.

[0027] The heating tube 5 of heating zone 1 2 is connected to the heating tube 5 of heating zone 2 3 through a bridge protection tube 6, and the heating tube 5 of heating zone 2 3 is connected to the heating tube 5 of heating zone 3 4 through a bridge protection tube 6. A bridge hole is provided below the groove 11 on the back foam of the car seat 1, and a bridge protection tube 6 is provided in the bridge hole. The heating tube 5 passes through the bridge hole through the bridge protection tube 6. The bridge protection tube 6 is a metal tube, the outer layer of the metal tube is provided with a rubber layer, and the inner layer of the metal tube is provided with a plastic tube added with a brominated flame retardant. Figure 5 As shown, at the place where the heating tube 5 is connected to the bridge protection tube 6, the two ends of the bridge protection tube 6 are inserted into the fracture of the outer flame retardant tube 7 of the heating tube 5, and the heating wire 9 passes through the bridge protection tube 6. There is only the heating wire 9 in the bridge protection tube 6, and there is no heating tube 5. Figure 3 As shown, the original heating wire 9 is bent close to the transition groove 11 at 90 degrees. Figure 4 As shown, the bending parts of the bridge protection tube 6 are all obtuse angles, so that the heating wire 9 can pass smoothly, which will not affect the use of the groove 11 and can make the bending angle of the heating wire 9 smooth, thereby increasing the service life of the heating wire 9.

[0028] Therefore, the utility model adopts the above-mentioned automobile seat heating structure, which can solve the problem that the traditional heating wire 9 has a large bending angle when transitioning to the groove 11 of the automobile seat 1, thereby reducing the service life of the heating wire 9.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that they can still modify or replace the technical solution of the utility model with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the utility model.
