In winter, as the temperature drops, the battery activity also decreases, resulting in a decrease in cruising range. How to increase the cruising range of electric two-wheelers in winter has become a concern for consumers. In the prior art, due to limited space in electric two-wheelers, a heating device for heating the battery is usually not provided, and the battery heating device in the existing electric vehicle is too large to be used on a two-wheeler.
[0003] Therefore, it is urgent to propose a heating device which can be used on an electric two-wheeled vehicle and has a small volume and a good heating effect. Utility Model Content
[0004] The first object of the utility model is to provide a heating device for an electric two-wheeled vehicle, which has multiple functions such as heating, heat preservation, insulation protection, etc., and has a simple structure and a small size.
[0005] The second object of the utility model is to provide an electric two-wheeled vehicle, which can heat the battery when the ambient temperature is low to ensure the battery activity, thereby ensuring the cruising range of the battery two-wheeled vehicle.
[0006] To achieve this purpose, the utility model adopts the following technical solutions:
[0007] The utility model discloses a heating device for an electric two-wheeled vehicle, comprising: a heating element, the heating element having a first side and a second side arranged opposite to each other; a first insulating layer, the first insulating layer being arranged on the first side of the heating element; a second insulating layer, the second insulating layer being arranged on the second side of the heating element; a reflecting layer, the reflecting layer being arranged on a side of the second insulating layer away from the heating element; and a heat-insulating layer, the heat-insulating layer being arranged on a side of the reflecting layer away from the second insulating layer.

[0009] In some embodiments, the heating element is provided with a conductive terminal, and the conductive terminal is used to connect to an external power source.
[0010] In some specific embodiments, the first insulating layer is provided with an avoidance groove corresponding to the conductive terminal, and at least a portion of the conductive terminal is located in the avoidance groove.
[0011] In some more specific embodiments, the heating device of the electric two-wheeled vehicle further includes an insulating protection member, which is connected to the first insulating layer and covers the conductive terminal.
[0012] In some embodiments, the first insulating layer is a PET layer; and / or: the second insulating layer is a PET layer.
[0013] In some embodiments, the reflective layer is an aluminum foil layer or a copper foil layer.

[0027] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.
[0028] The utility model discloses a heating device for an electric two-wheeled vehicle (hereinafter referred to as the heating device), such as Figure 1 and Figure 2 As shown, the heating device includes a heating element 100, a first insulating layer 200, a second insulating layer 300, a reflective layer 400 and a heat preservation layer 500. The heating element 100 has a first side and a second side arranged opposite to each other. The first insulating layer 200 is arranged on the first side of the heating element 100, the second insulating layer 300 is arranged on the second side of the heating element 100, the reflective layer 400 is arranged on the side of the second insulating layer 300 away from the heating element 100, and the heat preservation layer 500 is arranged on the side of the reflective layer 400 away from the second insulating layer 300. It can be understood that the heating element 100 is arranged between the first insulating layer 200 and the second insulating layer 300, so as to achieve the purpose of insulation protection, prevent water and dust from entering, reduce the probability of short circuit of the heating element 100, and improve the life of the heating device. In the actual working process, the heat generated by the heating element 100 is transferred downward, resulting in a decrease in heat utilization. The reflective layer 400 can reflect the heat transferred downward by the heating element 100 and transfer the heat upward instead, so that the heat is released from one side of the heating device in the actual working process, which is conducive to improving the heat utilization efficiency. The additional heat preservation layer 500 can slow down the downward dissipation of heat and play a role in heat preservation, thereby further improving the heat utilization efficiency. Since the heating device only includes the first insulating layer 200, the heating element 100, the second insulating layer 300, the reflective layer 400 and the heat preservation layer 500, the structure is simple and the volume is small.
[0029] In some embodiments, reference Figure 2 As shown, the heating element 100 is a heating wire, and the heating wire is a U-shaped structure. Thus, the heating efficiency can be guaranteed, and the floor space of the heating element 100 can be reduced, which is conducive to the miniaturization design of the heating device.
[0030] In some embodiments, reference Figure 2As shown, the heating device includes a back adhesive layer 600, which is arranged on the side of the thermal insulation layer 500 away from the reflective layer 400, and the back adhesive layer 600 is used to adhere the heating device of the electric two-wheeled vehicle to an external device. It can be understood that the additional back adhesive layer 600 can easily adhere the heating device to the battery compartment of the vehicle body, thereby facilitating the installation of the heating device. At the same time, the back adhesive layer 600 can better fix the heating device and prevent the heating device from being damaged due to movement during use, which is conducive to extending the service life of the heating device.
[0031] Of course, in other embodiments of the present invention, the heating device may also be fixed to an external device by means of connecting members such as screws, and is not limited to the adhesive installation method of the adhesive layer 600 of the present embodiment.
[0032] In some embodiments, reference Figure 2 As shown, the heating element 100 is provided with a conductive terminal 700, which is used to connect to an external power source. It is understandable that the connection with the external power source is realized through the conductive terminal 700, which is convenient for lead-in, thereby improving the connection reliability between the heating element 100 and the external power source and avoiding the occurrence of a circuit breaker.
[0033] In some specific embodiments, reference Figure 2 As shown, the first insulating layer 200 is provided with an escape groove corresponding to the conductive terminal 700, and at least a portion of the conductive terminal 700 is located in the escape groove. It can be understood that the escape groove is provided in the first insulating layer 200, which can ensure the lead-out of the conductive terminal 700, and at least a portion of the conductive terminal 700 is located in the escape groove, which can also seal and protect the connection position between the conductive terminal 700 and the heating element 100, and prevent water or dust from falling into the connection position between the conductive terminal 700 and the heating element 100, thereby reducing the probability of a short circuit in the heating element 100.
[0034] In some more specific embodiments, reference Figure 2 As shown, the heating device of the electric two-wheeled vehicle includes an insulating protective member 800, which is connected to the first insulating layer 200 and covers the conductive terminal 700. It can be understood that the insulating protective member 800 covers the conductive terminal 700, has waterproof insulation and buffering effects, prevents the conductive terminal 700 from short-circuiting when it encounters water, and protects the conductive terminal 700 from impact, thereby improving the working reliability of the heating device and extending the working life of the heating device.
[0035] In some embodiments, the first insulating layer 200 is a PET (polyethylene glycol terephthalate) layer. It is understandable that PET has excellent physical and mechanical properties in a wide temperature range, and its operating temperature can reach 120°C or even higher, and its electrical insulation is excellent. Even at high temperature and high frequency, it not only has good electrical insulation, but also has good creep resistance, fatigue resistance, friction resistance, and dimensional stability. The PET layer is used as the first insulating layer 200, and its good high temperature resistance is used so that the first insulating layer 200 will not shrink or deform when heated, and its good electrical insulation is used so that the first insulating layer 200 can reduce the probability of short circuit in the heating element 100. Optionally, the first insulating layer 200 is a transparent film, which can better transfer heat and improve heat utilization.
[0036] In some embodiments, the second insulating layer 300 is a PET (polyethylene glycol terephthalate) layer. It is understandable that PET has excellent physical and mechanical properties in a wide temperature range, and the operating temperature can reach 120°C or even higher. It has excellent electrical insulation, and even at high temperature and high frequency, its electrical insulation is still good. It has good creep resistance, fatigue resistance, friction resistance, and dimensional stability. The PET layer is used as the second insulating layer 300, and its good high temperature resistance is used so that the second insulating layer 300 will not shrink or deform when heated. Its good electrical insulation allows the second insulating layer 300 to reduce the probability of short circuits in the heating element 100. Optionally, the second insulating layer 300 is a transparent film, which can better transfer heat and improve heat utilization.
[0037] Of course, it should be additionally explained here that in other embodiments of the present invention, the first insulating layer 200 and the second insulating layer 300 can both be made of other high temperature resistant and insulating materials, and are not limited to the above limitations.
[0038] In some embodiments, the reflective layer 400 is an aluminum foil layer or a copper foil layer. It is understandable that the aluminum foil layer and the copper foil layer can better realize the reflection function. Of course, in other embodiments of the present invention, the material of the reflective layer 400 can also be selected from other materials according to actual needs, and is not limited to the above description.
[0039] In some embodiments, the thermal insulation layer 500 is an EPP layer. It is understandable that EPP has many advantages such as water-proof and moisture-proof, shockproof, soundproof, heat-insulating, good plasticity, strong toughness, recycling, environmental protection, and strong impact resistance. Using EPP as the thermal insulation layer 500 can not only ensure the heat preservation ability but also play the role of water-proof and moisture-proof and buffering, which not only improves the heat utilization efficiency, but also protects the heating device, which is conducive to extending the service life of the heating device.
[0040] In some embodiments, the length of the first insulating layer 200 is equal to the length of the second insulating layer 300 and is greater than the length of the heating element 100; the length of the first insulating layer 200 is equal to the width of the second insulating layer 300 and is greater than the width of the heating element 100. It is understandable that the first insulating layer 200 and the second insulating layer 300 have the same size and are greater than the size of the heating element 100, which can ensure that the heating element 100 is encapsulated between the first insulating layer 200 and the second insulating layer 300, improve the insulation protection function of the heating element 100, better prevent water and dust from entering, and further reduce the probability of short circuit of the heating element 100, thereby further improving the life of the heating device.
[0041] The utility model also discloses an electric two-wheeled vehicle, comprising a vehicle body and the aforementioned heating device, wherein the vehicle body has a battery compartment for accommodating batteries, and the heating device is arranged at the bottom of the battery compartment and is used to heat the batteries. Due to the aforementioned heating device, the electric two-wheeled vehicle can heat the batteries in a low ambient temperature to ensure the battery activity, thereby ensuring the battery life of the battery two-wheeled vehicle.
