Description

Automobile seat heating pad beneficial to rapid temperature rise

Technical Field

The utility model relates to the technical field of automobile seats, in particular to an automobile seat heating pad beneficial to rapid temperature rise.

Background

As the automobile industry develops, consumers increasingly pay more attention to the comfort of riding automobiles. In order to improve the riding comfort of a user, many high-vehicle models and luxury vehicles are provided with a seat heating function, and the seat heating function is to heat a seat by using an electric heating wire, so that the riding experience of the user in cold weather is improved.

In the prior art, the seat heating function is usually accomplished by single heater strip, and this heater strip distributes inside the seat with the mode of coiling, and the technical problem that this overall arrangement heater strip exists is that, the impedance of heating module is higher, and the electric heating function starts the back, can reach preset temperature for a long time, seriously influences user's the experience of riding.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model provides an automobile seat heating pad beneficial to rapid temperature rise, so as to solve the technical problem of slow heating temperature rise in the prior art.

In order to achieve the purpose, the technical scheme of the utility model is as follows:

the utility model provides a car seat heating pad that helps rapid heating up which the key lies in: the heating mattress comprises a mattress body made of non-woven fabrics, wherein at least two heating wires are paved on the mattress body, the heating wires are electrically connected in parallel, each heating wire comprises a conducting layer positioned in a core part and an insulating layer positioned outside, and the conducting layer is made of carbon fibers.

By adopting the heating pad, the heating wires are arranged on the pad body in a parallel connection mode, so that the seat has smaller impedance when being heated, and after the heating function is started, the seat can be rapidly heated, and the user experience is better. Simultaneously, the heater strip that uses carbon fiber material not only has higher thermal conversion efficiency and tensile strength, and seat temperature distribution's homogeneity also can be showing and is promoted moreover.

Preferably, the method comprises the following steps: the insulating layer is made of Teflon.

Preferably, the method comprises the following steps: the heating wire is fixed on the cushion body through sewing threads.

Preferably, the method comprises the following steps: the heating wire is fixed on the cushion body in an adhesive manner.

Preferably, the method comprises the following steps: the number of the heating wires is four.

Preferably, the method comprises the following steps: the ends of the heating wires are connected in parallel through terminals, and the terminals are connected with conductive cables.

Compared with the prior art, the utility model has the beneficial effects that:

1. the heating wires are arranged on the cushion body in a parallel connection mode, the seat has smaller impedance when being heated, the seat can be heated rapidly after the heating function is started, and the user experience is better.

2. The heating wire made of the carbon fiber material has the technical advantages of high heat conversion efficiency, high tensile strength, good temperature distribution uniformity, stable performance, no broken wire arcing, long service life and the like.

Detailed Description

The present invention will be further described with reference to the following examples and the accompanying drawings.

As shown in fig. 1 and 2, an automobile seat heating mat for facilitating rapid temperature rise mainly comprises a mat body 1 and heating wires 2, wherein the mat body 1 is made of non-woven fabric, the number of the heating wires 2 is at least two, the heating wires 2 are connected in parallel, for convenience of parallel connection, two terminals 4 are arranged on the mat body 1, the ends of the heating wires 2 are connected in parallel through the terminals 4, and the terminals 4 are connected with conductive cables 5.

When the seat heating structure is used, current is introduced into each heating wire 2 through the conductive cable 5, compared with a seat heating structure with a single traditional heating wire, the heating pad with the plurality of heating wires 2 connected in parallel has smaller impedance, and the seat can be ensured to be heated up quickly.

As shown in fig. 2, in the present embodiment, the number of the heating wires 2 is 4.

As shown in fig. 3, the heating wire 2 includes a conductive layer a at the core and an insulating layer b at the outside, the conductive layer a being made of carbon fiber, and the insulating layer b being made of teflon, wherein the carbon fiber has many advantages as the heating wire, such as: 1. the electric heat conversion efficiency is high, and the electric energy is saved; 2. the tensile strength is high, the strength of the carbon fiber is 6-10 times higher than that of the metal wire under the same current load area, and the carbon fiber cannot be broken in the using process; 3. the broken wire can not generate electric arc, and fire can be effectively avoided; 4. light weight, stable chemical performance and long average service life.

As shown in fig. 3, in order to facilitate the fixing of the heating wire 2, the heating wire 2 may be fixed on the cushion body 1 by sewing thread 3, or may be fixed on the cushion body 1 by gluing or the like.

Finally, it should be noted that the above-mentioned description is only a preferred embodiment of the present invention, and those skilled in the art can make various similar representations without departing from the spirit and scope of the present invention.
