Description
Technical Field
[0001] The utility model relates to the technical field of electric bicycle supplies, in particular to a heatable and dryable flexible laminate, an electric bicycle seat cushion and a handlebar. Background Art
[0002] With technological advancements and improvements in people's living standards, electric bicycles (hereinafter referred to as electric bicycles) have become almost an essential means of transportation for families. However, electric bicycles present two major pain points in daily use, which hinder the user experience. First, because electric bicycles are occasionally exposed to the open air, they are inevitably affected by rain, snow, frost, and other factors, which affects the user's timely use of the bicycle and the user experience. Second, in the hot summer, even a short period of exposure to the sun can cause the seat cushion to heat up rapidly, which also affects the user's timely use of the bicycle and the user experience.
[0003] To address the above two pain points, the traditional solution is to install a waterproof dust cover. This method can prevent rain and snow from wetting the seat cushion to a certain extent, but after the waterproof dust cover is wet, it still needs to be wiped clean with paper towels or other items, and this solution cannot quickly cool down the tram seat cushion after being exposed to the sun.
[0004] Another approach, such as that proposed in Chinese invention patent application CN117341865A, involves a semiconductor temperature-controlled ventilated seat cushion for electric bicycles and a control method thereof. This method involves installing semiconductor blocks inside the seat cushion to dry and rapidly cool the cushion. While this method can theoretically achieve both drying and rapid cooling of electric bicycle seat cushions, the semiconductor blocks' limited heating and cooling area prevent uniform heating of the seat cushion, and placing semiconductor blocks over a large area within the seat cushion is impractical. Furthermore, due to size limitations, the semiconductor blocks cannot be integrated into the handlebars, thus failing to address the issue of handlebar icing in winter.
[0005] As a new type of material, carbon nanotube composite film has excellent heat generation, thermal conductivity, electrical conductivity, ductility and flexibility. It is one of the hot topics in material research today and has shown broad application prospects in many industries. Summary of the Invention
[0006] In order to solve the problem of drying and cooling an electric bicycle seat and the problem of ice forming on an electric bicycle handlebar in winter, the utility model provides a heatable and dryable flexible laminate, an electric bicycle seat and a handlebar.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0032] In order to more clearly understand the above objects, features and advantages of the present utility model, the present utility model will be further described in detail below with reference to the drawings and specific embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.
[0033] Embodiment 1
[0034] As Figure 1As shown in the figure, this embodiment provides a heatable and dryable flexible laminate, which includes a flexible substrate 1, a first carbon nanotube composite film 2, and a controller;
[0035] The flexible substrate 1 and the first carbon nanotube composite film 2 are layered and integrated;
[0036] The first carbon nanotube composite film is provided with electrical connection points, which are connected to the controller through the electrical connection points to generate heat under the control of the controller.
[0037] Specifically, the flexible substrate 1 is made of a woven material; the first carbon nanotube composite film 2 is prepared on the upper surface of the flexible substrate 1.
[0038] In the heatable and dryable flexible laminate of this embodiment, through the integrated design of the flexible substrate and the carbon nanotube composite film, the flexible laminate can be uniformly heated and dried.
[0039] The heatable and dryable flexible laminate in this embodiment mainly utilizes the flexibility and electrothermal properties of the carbon nanotube composite film;
[0040] One is to utilize the flexibility of the carbon nanotube composite film to prepare it on the upper surface of the flexible substrate, so that the whole laminate has flexible characteristics;
[0041] The other is to utilize the electrothermal property of the carbon nanotube composite film. By supplying power to the carbon nanotube composite film and heating the carbon nanotube composite film, the purpose of uniformly heating and drying the upper surface of the flexible substrate can be achieved.
[0042] The carbon nanotube composite film has excellent electrical conductivity and electrothermal properties. When an electric current is applied, the carbon nanotube composite film can efficiently convert electrical energy into heat energy. By adjusting the current flowing through the carbon nanotube composite film, the heating temperature can be precisely controlled.
[0043] In some exemplary embodiments, two copper foils are provided at both ends of the first carbon nanotube composite film 2 as electrical connection points, which are respectively connected to the positive and negative poles of the power supply for power supply. The controller can be uniformly controlled by an eight-bit single-chip microcomputer.
[0044] Embodiment 2
[0045] This embodiment provides an electric bicycle seat cushion, as Figure 2 and Figure 3 shown, which includes a seat cushion body 5, and also includes the heatable and dryable flexible laminate, a second carbon nanotube composite film 6, and a semiconductor refrigerating sheet 7 provided in the embodiment 1 and covering the outer surface of the seat cushion body 5;
[0046] The semiconductor refrigeration chip 7 has its refrigerating surface adhesively attached to the surface film 3 and is electrically connected to the controller, so as to generate cooling capacity under the control of the controller to cool down the seat of the electric bicycle.
[0047] The heat dissipation surface of the semiconductor refrigeration chip 7 is prepared on the second carbon nanotube composite film 6 for heat dissipation of the heat dissipation surface of the semiconductor refrigeration chip 7.
[0048] In some exemplary embodiments, a surface film 3 is provided on the upper surface of the first carbon nanotube composite film 2 of the heatable and dryable flexible laminate; a flexible temperature and humidity sensor 4 is provided on the upper surface of the surface film 3; the flexible temperature and humidity sensor 4 is connected to the controller and is used to collect the temperature and humidity on the upper surface of the surface film 3. Specifically, the flexible temperature and humidity sensor 4 is connected to the controller through wires with the positive and negative copper foils of the power supply of the heatable and dryable flexible laminate. The flexible temperature and humidity sensor can adopt AHT3001. The surface film 3 can adopt a leather material, and a surface fabric layer 13 is provided on the upper surface of the surface film 3 to cover and isolate the flexible temperature and humidity sensor.
[0049] For the realization of the heating and drying function of the electric bicycle seat, it is achieved by utilizing the electrothermal property of the first carbon nanotube composite film. During actual operation, the controller compares the preset humidity with the data transmitted back by the flexible temperature and humidity sensor, thereby determining the execution of the heating and drying function. In rainy or snowy weather with high humidity and the need for rapid heating and drying, when the flexible temperature and humidity sensor detects that the humidity is less than the preset humidity by 10 units, the controller drives the first carbon nanotube composite film to operate at full power; when the flexible temperature and humidity sensor detects that the humidity is less than the preset humidity within 10 units, the controller drives the first carbon nanotube composite film in a manner similar to PID control to heat and dry until the preset humidity.
[0050] The realization of the heating and drying function of the electric bicycle seat is the same as that of the heatable and dryable flexible laminate, which will not be elaborated here.
[0051] For the realization of the refrigeration function of the heatable and dryable flexible laminate, it is achieved by utilizing the thermal conductivity of the carbon nanotube composite film and the refrigeration chip. During actual operation, just set the desired temperature, and the controller compares the set temperature with the data transmitted back by the flexible temperature and humidity sensor, thereby controlling the refrigeration chip to achieve cooling. Further, in summer when the ambient temperature is relatively high and rapid cooling is required, when the temperature set by the user is less than the temperature detected by the flexible temperature and humidity sensor by 10 °C, the controller drives the refrigeration chip to operate at full power; when the temperature set by the user is less than the temperature detected by the flexible temperature and humidity sensor within 10 °C, the controller drives the refrigeration chip in a manner similar to PID control and finally stabilizes the temperature of the electric bicycle seat within the range of ±2 °C of the temperature set by the user.
[0052] In this embodiment, a semiconductor refrigerating sheet is provided at the bottom of the heat - adjustable and drying - capable flexible laminate of the electric bicycle seat for rapid cooling of the electric bicycle seat. In the rapid - cooling function, the first carbon nanotube composite film is responsible for heat conduction. That is, by using the excellent heat - conducting performance of the carbon nanotube composite film, the semiconductor refrigeration effect is quickly and evenly transmitted to the surface of the electric bicycle seat. Since the semiconductor refrigerating sheet emits a large amount of heat from its heat - dissipating surface during operation, the heat - dissipating effect will affect the refrigeration effect. The traditional heat - dissipating solution is to cover the heat - dissipating surface of the semiconductor refrigerating sheet with an aluminum block or a copper sheet for heat conduction, and then dissipate the heat through a fan. The traditional heat - dissipating solution of stacking the semiconductor refrigerating sheet - aluminum block (or copper sheet) - cooling fan will occupy a large amount of storage space under the electric bicycle seat, affecting the practicality of the electric bicycle.
[0053] In some exemplary embodiments, taking advantage of the heat - conducting property of the carbon nanotube composite film, the heat on the heat - dissipating surface of the semiconductor refrigerating sheet is diverted through the second carbon nanotube composite film to a duct 8 where the air inlet 81 and the air outlet 82 designed under the seat body 5 are both in communication with the outside, and the heat is taken out through the duct 8. This design makes flexible use of the space under the electric bicycle seat and basically does not occupy the storage space 9 of the electric vehicle while meeting the function. Related hardware such as wires and controllers is placed in the functional space area 10; the duct 8 is located under the semiconductor refrigerating sheet 7, and a second carbon nanotube composite film 6 is arranged between the semiconductor refrigerating sheet 7 and the duct 8 for dissipating the heat from the heat - dissipating surface of the semiconductor refrigerating sheet 7. Preferably, an air - inlet fan electrically connected to the controller can be arranged at the air inlet 81 of the duct 8 to introduce air into the duct 8 and take away the heat on the heat - dissipating surface of the semiconductor refrigerating sheet 7, ensuring the refrigeration effect.
[0054] In some exemplary embodiments, for the drying and cooling functions, two control means of physical - button control and remote control are provided. That is, physical buttons for turning on and off the heating - drying and refrigeration functions are set; the physical buttons are electrically connected to the controller. The controller is connected to a remote - communication module for remote communication with a mobile terminal to remotely turn on and off the heating - drying and refrigeration functions. The physical buttons are integrated into the vehicle handle, and the temperature and humidity data are transmitted to and displayed on the dashboard. Through the physical buttons, the user can manually turn on and off the drying function and can also turn on the rapid - cooling function. The user can also remotely control the drying function and the rapid - cooling function using the corresponding mobile terminal.

[0056] This embodiment provides an electric bicycle handle, as Figure 4 shown, which includes a handle body 11 and further includes the heat - adjustable and drying - capable flexible laminate described in Embodiment 1 that is coated on the outer surface of the handle.
[0057] In some exemplary embodiments, a plastic outer shell layer 12 is provided on the upper surface of the heatable and dryable flexible laminate to isolate and protect the heatable and dryable flexible laminate.
[0058] The handlebar of the electric bicycle in this embodiment can be quickly heated and dried in snowy weather. Among them, the realization of the heating and drying function of the handlebar of the electric bicycle is the same as that of the heatable and dryable flexible laminate, which will not be elaborated here.
[0059] In some exemplary embodiments, for the drying function, two control means of physical button control and remote control are provided. That is, a physical button for turning on and off the heating and drying function is provided; the physical button is electrically connected to the controller. The controller is connected to a remote communication module for remote communication with a mobile terminal to remotely turn on and off the heating and drying function. The physical button is integrated into the handlebar, and the temperature and humidity data is transmitted to the dashboard for display. Through the physical button, the user can manually turn on and off the drying function, and the user can also remotely control the drying function using the corresponding mobile terminal.
[0060] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
