Technical Field
[0001] This disclosure relates to the field of vehicle technology, and more specifically, to a seat belt and a vehicle. Background Technology
[0002] In the automotive field, seat belts are safety devices designed to restrain occupants during a vehicle collision to prevent them from colliding with the steering wheel, dashboard, and other components. With the development of the automotive industry, seat belt heating has become a reality. However, in related technologies, seat belts are typically heated using carbon fiber heating wires, which suffer from poor heating uniformity and are prone to breakage. Therefore, improving the uniformity of seat belt heating and the breakage resistance of the heating material to provide occupants with a comfortable driving experience is a technical problem that urgently needs to be solved. Utility Model Content

[0023] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.
[0024] In this disclosure, unless otherwise stated, directional terms such as "inner" and "outer" refer to the inner or outer contours of a component or structure itself; the same reference numeral in different reference drawings denotes the same element.
[0025] A first aspect of this disclosure is to provide a seat belt, with reference to Figures 1 to 4 As shown, the seat belt includes a belt body 1 and a graphene heating module 2, wherein a receiving cavity 101 is formed inside the belt body 1; the graphene heating module 2 is at least partially disposed inside the receiving cavity 101 and extends along the length direction of the belt body 1, and the graphene heating module 2 is used to heat the belt body 1.
[0026] With the above solution, namely the seat belt provided in this disclosure, when the seat belt is heated, the graphene heating module 2 can be used to heat the belt body 1 by heating the graphene inside the graphene heating module 2. The graphene heating module 2 extends along the length of the belt body 1, which can improve the thermal uniformity of the belt body 1 when the graphene heating module 2 heats the belt body 1, thereby improving the comfort experience of the driver and passengers.
[0027] It should be noted that the graphene heating module 2 is heated by radiation.
[0028] In addition, the connection method between the graphene heating module 2 and the belt 1 can be any suitable method. For example, when the graphene heating module 2 is inserted into the receiving cavity 101 of the belt 1, in order to ensure that the graphene heating module 2 can be stably installed in the receiving cavity 101, the graphene heating module 2 and the belt 1 can be fixed by stitching them together.
[0029] In some implementations, reference Figures 1 to 4 As shown, the graphene heating module 2 includes an insulating layer 230 and a base layer 210 and a graphene layer 220 disposed between the insulating layer 230. In this way, the insulating layer 230 can insulate the graphene layer 220 from the external belt body 1, thereby preventing electric shock due to current flowing through the belt body 1 when the graphene layer 220 is heated. This improves the safety of the safety belt during heating and use. The base layer 210 can be connected to the graphene layer 220 before assembling the belt body 1 and the graphene heating module 2, as can be seen from... Figure 3As shown, before assembling the seat belt, the layers in the graphene heating module 2 need to be spliced and assembled. After using the base layer 210 as the base, the graphene layer 220 can be deposited on the base layer 210 by coating or chemical vapor deposition. Then, the insulating layer 230 is attached to the other side of the graphene layer 220 and the base layer 210 to complete the assembly of the graphene heating module 2. After the assembly is completed, the graphene heating module 2 can be inserted into the receiving cavity 101 of the belt body 1 to complete the assembly of the complete belt.
[0030] It should be noted that the material used for the substrate 210 can be any material with good bonding performance and high flexibility, and the material used for the insulating layer 230 can be any material with excellent insulating performance. This disclosure will provide detailed examples of the materials of the substrate 210 and the insulating layer 230 below, and will not elaborate further here.
[0031] In some implementations, reference Figure 4 As shown, the graphene layer 220 is located on one or both sides of the substrate layer 210. In this way, in... Figure 3 In the example, by arranging graphene layers 220 on both sides of the base layer 210, the two graphene layers 220 can improve the heat storage and heating effect of the graphene heating module 2. That is, by heating with more graphene layers 220, the heating amount of the seat belt can be increased, and more graphene layers 220 can store more heat, thereby preventing the graphene layers 220 from suddenly dropping in temperature when heating stops, which can improve the comfort of the driver and passengers.
[0032] It should be noted that Figure 3 and Figure 4 These are two different embodiments of the graphene heating module 2. Figure 3 In this embodiment, the graphene layer 220 is located on one side of the substrate layer 210. Figure 4 In this embodiment, the graphene layer 220 is located on both sides of the substrate layer 210. In specific applications, the appropriate position of the graphene layer can be selected according to the power design of the seat belt. This disclosure does not impose specific limitations in this regard.
[0033] In some implementations, reference Figure 3 and Figure 4 As shown, the insulation layer 230 includes at least one of fiberglass cloth and nonwoven fabric. In this way, both fiberglass cloth and nonwoven fabric have the advantages of being lightweight, corrosion-resistant, environmentally friendly, heat-resistant, having strong insulation properties, and high structural strength.
[0034] In some implementations, reference Figure 3 and Figure 4As shown, the substrate 210 includes at least one of fiberglass cloth, nonwoven fabric, polyethylene terephthalate (PET), and polyimide (PI). In this way, fiberglass cloth and nonwoven fabric possess the advantages of the above-described embodiments, while PET material has good mechanical strength and toughness, good heat resistance and insulation properties, and PI material has advantages such as good heat resistance, corrosion resistance, insulation, and flame retardancy. Using one or more of the above materials in combination as the substrate 210 can improve the performance of the substrate 210.
[0035] In some implementations, reference Figure 1 and Figure 2 As shown, the seat belt also includes a temperature sensing module 3 and a controller 4. The temperature sensing module 3 is located on the graphene heating module 2 to monitor the temperature of the graphene heating module 2. The controller 4 is electrically connected to the graphene heating module 2 and the temperature sensing module 3 to control the heating temperature of the graphene heating module 2. In this way, the temperature sensing module 3 can be used to detect the real-time temperature of the graphene heating module 2. The temperature sensing module 3 can be a temperature sensor or other device connected to the graphene heating module 2. The controller 4 can work with the temperature sensing module 3 to adjust the heating temperature. For example, when the occupants feel that the heating temperature is too high, the controller 4 can lower the heating temperature of the graphene heating module 2; when the occupants feel that the heating temperature is too low, the controller 4 can raise the heating temperature of the graphene heating module 2. Furthermore, the controller 4 can include a central control screen inside the vehicle and an adjustment knob that can adjust the heating temperature. In this way, the temperature sensing module 3 can receive the real-time temperature of the graphene heating module 2 and feed it back to the controller 4. The controller 4 can also receive the real-time temperature feedback and can adjust the instantaneous heating temperature of the graphene heating module 2 under the control of the occupants.
[0036] In some implementations, reference Figure 1 and Figure 2 As shown, multiple temperature sensing modules 3 are arranged at intervals along the extension direction of the graphene heating module 2. In this way, multiple temperature sensing modules 3 can simultaneously detect the temperature at multiple different locations of the graphene heating module 2. The driver and passengers can then obtain the real-time temperature of multiple different locations of the graphene heating module 2 according to the controller 4, and thus control the heating degree of each location of the graphene heating module 2 to be the same, or allow the belt 1 to be attached to the driver and passengers' location for targeted heating, etc.
[0037] Furthermore, it should be noted that, considering the cost and manufacturing process of the seat belt, the temperature sensing module 3 can also be arranged as a single unit on the graphene heating module 2, thereby saving the cost and manufacturing difficulty of the seat belt. The number of temperature sensing modules 3 can be reasonably arranged according to the actual usage requirements of the seat belt, that is, it can be a single unit or multiple units, and this disclosure does not make any specific limitation in this regard.
[0038] In some implementations, reference Figure 1 and Figure 2 As shown, the temperature sensing module 3 is located in the area of the belt body 1 corresponding to the shoulder strap and / or waist belt area. (Reference) Figure 1 As shown, when the seat belt is installed in a vehicle, it typically includes two areas: a shoulder strap and a lap belt. The temperature sensing module 3 provided in this disclosure can be positioned appropriately according to the actual installation of the seat belt. For example, the temperature sensing module 3 can be positioned only at the shoulder strap position of the belt body 1 to detect the heating temperature of the shoulder strap position, or it can be positioned only at the lap belt position of the belt body 1 to detect the heating temperature of the lap belt position, or it can be positioned at both the shoulder strap and lap belt positions to detect the heating temperature of both the shoulder strap and lap belt simultaneously. All three methods can be arranged according to the actual situation, and this disclosure does not limit them.
[0039] In some implementations, reference Figure 1 As shown, the receiving cavity 101 is constructed as a cavity with openings at both ends along the length of the belt 1. The graphene heating module 2 is inserted into the receiving cavity 101, and the length of the graphene heating module 2 is greater than the length of the receiving cavity 101. In this way, when the length of the graphene heating module 2 is greater than that of the belt 1, in the event of seat belt tightening, such as during sudden braking, the belt 1 can be tightened first. The longer graphene heating module 2 prevents the graphene layer 220 inside the module from being broken when the belt tightens, thus providing a certain tensile allowance for the graphene layer 220 and preventing breakage. This method can improve the service life of the graphene layer 220 and ensure subsequent heating effects.
[0040] A second aspect of this disclosure is to provide a vehicle that includes the seat belt mentioned in the above specific embodiments, and the seat belt has all the beneficial effects of the above embodiments. In this disclosure, the vehicle can be a new energy vehicle such as a fuel vehicle, a plug-in hybrid vehicle, or a pure electric vehicle, or it can be a hydrogen fuel cell vehicle.
[0041] The preferred embodiments of the present disclosure have been described in detail above with reference to the accompanying drawings. However, the present disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.
[0042] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.
[0043] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
