In addition, in the following description, specific details are provided in order to provide a thorough understanding of the examples. However, it will be understood by those skilled in the art that the present invention may be practiced without these specific details.
The temperature detection of the heating layer of the steering wheel is usually realized based on an NTC thermistor and is limited in the space of the steering wheel, the temperature detection of the heating layer of the steering wheel is usually realized by placing a single heat-sensitive element (NTC element) at a specific position of the heating layer, and enabling a probe of the heat-sensitive element to be in lap joint or butt joint with a heating wire forming the heating layer, so that the heat-sensitive element timely detects the temperature of the heating layer, and finally the heat-sensitive element feeds the temperature back to a control unit to realize the temperature adaptive adjustment of the steering wheel.
The heating wires in the heating layers are all provided with intervals, in the process that the steering wheel is used, the thermosensitive element can move on the heating layers, so that the probe of the thermosensitive element is separated from the heating wires, namely, the probe of the thermosensitive element is shifted to a non-heating area between the heating wires, which definitely leads to the fact that the probe of the thermosensitive element cannot accurately detect the temperature of the heating layers, so that the thermosensitive element cannot accurately detect the temperature change of the heating layers, namely, the temperature data detected by the thermosensitive element cannot represent the temperature change of the whole steering wheel heating layers. Therefore, if the temperature sensor cannot detect the correct temperature of the heating layer for a long time, the heating layer is also degraded rapidly.
Based on this, the embodiment of the present specification proposes a processing scheme: as shown in fig. 1, in the temperature detection structure of the present invention, the heat conduction unit 20 is used to transmit the temperature of the heating position or the abnormal heating position, and the heat sensitive unit 30 is used to detect the temperature of the heating position or the abnormal heating position through the heat conduction unit 20, so that the detection accuracy of the heating layer of the steering wheel is improved under different heating conditions.
The following describes the technical solutions provided by the embodiments of the present application with reference to the accompanying drawings.

As shown in fig. 1 to 2, an embodiment of the present invention provides a temperature detecting structure including a first film unit 10, a heat conducting unit 20, and a heat sensing unit 30. The first film unit 10 is arranged at a heating position or an abnormal heating position of the structure to be detected, wherein the abnormal heating position is a heating position when the structure to be detected is abnormal; the heat conducting unit 20 is arranged on one side, far away from the structure to be detected, of the first film unit 10 along the first film unit 10, the heat conducting unit 20 is arranged corresponding to the heating position or the abnormal heating position, and the heat conducting unit 20 is used for absorbing heat released at the heating position or the abnormal heating position; the thermo-sensitive unit 30 is disposed at a side of the heat conducting unit 20 away from the first film unit 10, and a thermo-sensitive probe of the thermo-sensitive unit 30 is in contact with the heat conducting unit 20 for detecting a surface temperature of the heat conducting unit 20 through the thermo-sensitive probe.
The structure to be detected can be a heating structure such as a steering wheel heating layer and a new energy automobile battery.
The abnormal heating position may be a position where the new energy automobile battery heats when being broken down or impacted, and the heat conduction area of the new energy automobile battery is increased through the heat conduction unit 20, so that whether the new energy automobile battery heats can be rapidly located.
Wherein the first membrane unit 10 is used for fixing the temperature detecting structure to a structure to be detected, such as to a steering wheel or to a battery waiting detecting structure.
The connection manner of the first membrane unit 10 and the structure to be detected includes, but is not limited to, adhesion.
The first film unit 10 is made of a heat conductive material, and when the first film unit 10 is connected to the structure to be detected through bonding, the glue used is a heat-resistant glue, such as a polyimide adhesive, a heat-resistant epoxy adhesive, a phenolic resin adhesive, a urea-formaldehyde resin adhesive, a silicone adhesive, and the like.
Wherein the first membrane unit 10 may be made of plastic.
Wherein at least one end of the first film unit 10 covers the heat generating position or the abnormal heat generating position so that the heat conducting unit 20 mounted thereon can absorb heat released at the heat generating position or the abnormal heat generating position.
Wherein the heat conduction unit 20 is used for absorbing heat released at a heat generation position or an abnormal heat generation position and raising its own temperature, so that the heat sensitive unit 30 mounted on the heat conduction unit 20 can accurately detect the temperature at the heat generation position or the abnormal heat generation position.
Wherein the heat conduction unit 20 has an area capable of covering a heat generation position or an abnormal heat generation position.
For example, in the case that the heating position is a heating wire, the minimum width or length of the heat conducting unit 20 is larger than the interval between adjacent heating wires, so as to avoid that the heat released by the heating wire cannot be directly obtained after the heat conducting unit 20 is displaced.
The heat conductive unit 20 is made of a heat conductive material such as graphene, a metal foil (copper foil), carbon fiber, silicone, or a composite material.
The heat conducting unit 20 is a sheet structure, and can deform to a certain extent according to the shape of the heating position or abnormal heating position of the structure to be detected, so as to be closely attached to the heating position or abnormal heating position.
The thermal unit 30 may be a thermistor such as NTC or PTC.
In some of these embodiments, the probe of the thermo-sensitive unit 30 may be disposed at any position on the heat conducting unit 20.
Preferably, the probe of the thermo-sensitive unit 30 is disposed at the center of the heat conductive unit 20.

In some embodiments, an adhesive layer (not shown in the figure) is arranged on one side of the first film unit 10 close to the structure to be detected and one side of the first film unit far from the structure to be detected; wherein, the adhesive layer that is close to one side of waiting to detect the structure sets up is used for pasting first membrane unit 10 on waiting to detect the structure, and the adhesive layer that one side of waiting to detect the structure set up is kept away from is pasted with heat conduction unit 20 and is connected.
The adhesive layer may be a glue layer, and the adhesive layer is made of heat-resistant glue.
In some embodiments, the size of the heat conducting unit 20 is smaller than that of the first film unit 10, and the adhesive layer disposed at the side far away from the structure to be detected is simultaneously in adhesive connection with the heat conducting unit 20 and the first film unit 10.
In some embodiments, when the size of the heat conducting unit 20 is larger than that of the first film unit 10, the heat conducting unit 20 may be adhered to the structure to be detected through a plurality of first film units 10 disposed at intervals.

Wherein, the heat conduction portion 22 can be bent along the axial direction of the placement portion 21 so as to be attached to the structure to be detected, thereby facilitating the heat conduction portion 22 to absorb heat released at the heat generating position or the abnormal heat generating position.
For example, in the case where the structure to be detected is a steering wheel heating layer, the placement portion 21 may be fixed to the steering wheel heating layer, and the heat conducting portion 22 may be bent, so that the heat conducting portion 22 is bent into an arc shape to be matched with the steering wheel heating layer, thereby being more tightly adhered to the steering wheel heating layer.
Further, the plurality of heat conducting portions 22 are arranged at intervals on the periphery of the placement portion 21, so as to be convenient to be attached to the heating position or the abnormal heating position.
For example, the heat conducting parts 22 may be two and respectively provided in a "(", ")" type structure, and the heat conducting parts 22 may be symmetrically provided at both sides of the placement part 21.
Still further, the heat conductive unit 20 may be provided in a petal shape having a plurality of heat conductive parts 22.

In some embodiments, the temperature detecting structure of the present invention further includes a second film unit 40, where the second film unit 40 is disposed to cover the first film unit 10, the heat conducting unit 20, and the heat sensing unit 30, so as to avoid exposing the heat conducting unit 20 and the heat sensing unit 30 to the outside.
The second film unit 40 may be adhered to the first film unit 10, the heat conducting unit 20, and the heat sensitive unit 30.
Wherein, one side of the second film unit 40 facing away from the heat conducting unit 20 is provided with a smooth insulating layer, and one side of the second film unit 40 close to the heat conducting unit 20 is provided with an adhesive layer, so that the second film unit 40 and the first film unit 10 are tightly adhered when the area of the heat conducting unit 20 is smaller than that of the first film unit 10.
Wherein, when the size of the heat conduction unit 20 is larger than that of the first film unit 10, the second film unit 40 is coated on the heat conduction unit 20 and the heat sensitive unit 30.
In some of these embodiments, the temperature sensing structure further includes a reinforcing plate 50 (not shown in the drawings), and the reinforcing plate 50 is disposed on the first film unit 10 and connected to the wires of the thermo-sensitive unit 30 through pads for connection with external connectors, thereby preventing the pads from being damaged by solder joints.
Further, the reinforcing plate 50 is provided in plurality and is provided at the bottom of the placement portion 21 to make the placement portion 21.
Wherein the reinforcing plate 50 is for supporting the placement portion 21 and the pads, and the reinforcing plate 50 is made of a heat conductive material.
The embodiment of the invention comprises a first film unit 10 with double-sided adhesive layers, a heat conducting unit 20 and a heat-sensitive unit 30, wherein the first film unit 10 plays roles of bonding the heat conducting unit 20 and isolating a heating position from the heat conducting unit 20, and the heat conducting unit 20 with good heat conductivity uniformly transmits the temperature of the heating position or the abnormal heating position, so that the uniform distribution of the temperature of the heating position or the abnormal heating position is realized, the heat-sensitive unit 30 is convenient for temperature detection, and the second film unit 40 is used for isolating peripheral materials and the heat-sensitive unit 30, so that the heat-sensitive unit 30 is prevented from being exposed to the outside.
