Description

Technical Field

[0001] The utility model relates to the technical field of automotive supplies, and particularly relates to an adaptive-size cup holder and a vehicle-mounted cup holder. Background Technique

[0002] With the development of technology and the improvement of living standards, drivers and passengers hope to drink heated or chilled beverages at any time during daily travel.

[0003] Currently, vehicle-mounted cup holders are a common automotive supply. Some existing vehicle-mounted cup holders use the hot air and warm air blown by the vehicle air conditioner to achieve heating and cooling of the cup holder. However, the heating and cooling speeds are very slow, the effects are not obvious, they do not have the function of rapid heating and cooling, and they cannot meet the needs of drivers and passengers to drink heated or chilled beverages at any time during daily travel.

[0004] There are also some vehicle-mounted cup holders that achieve heating and cooling functions by setting refrigeration and heating components in the cup holder. For example, the Chinese utility model patent with the publication number CN216374319U discloses a clamping-type vehicle-mounted hot and cold cup, including a refrigeration sheet and a clamping heat conduction component; the refrigeration sheet is used to generate cold and conduct the generated cold to the clamping heat conduction component; the clamping heat conduction component is used to clamp the beverage bottle and transfer the cold to the beverage bottle. When beverage bottles with different diameters are placed in the clamping-type vehicle-mounted hot and cold cup, the clamping heat conduction component can clamp the beverage bottle, the clamping heat conduction component contacts the surface of the beverage bottle, enhancing the heat conduction efficiency, and at the same time can prevent the beverage bottle from shaking, and the beverage bottle will not be jolted out when the vehicle is driving on a bumpy road section. Although a clamping heat conduction component suitable for beverage bottles with different diameters is designed, for some special-shaped bottle body structures such as those with a round upper part and a square lower part, it cannot play a good role in adapting to the bottle body structure, thus affecting the heating and cooling effects.

Detailed implementation manners

[0041] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific implementation manners. 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.

[0042] Embodiment 1

[0043] As Figure 1 , Figure 2 and Figure 3 shown, this embodiment provides a self-adaptive size cup holder, including: cup holder main body 1, refrigeration sheet 2, flexible heat conduction component 3 and a controller;

[0044] The flexible heat conduction component 3 includes a flexible material filling layer 31, a first surface coating film 32, a carbon nanotube composite film 33, and a second surface coating film 34 that are sequentially arranged along the inner wall of the cup holder main body; the flexible heat conduction component 3 is arranged in a surrounding manner within the cup holder main body 1 to form an inner cavity 4 for placing beverages;

[0045] The carbon nanotube composite film 33 is provided with electrical connection points for generating heat by being energized through the electrical connection points under the control of the controller;

[0046] The refrigeration sheet 2 is adhesively arranged on the surface of the carbon nanotube composite film 33 facing the second surface coating film 34, with the heat dissipation surface adhered to the surface of the carbon nanotube composite film 33 and the refrigeration surface facing the inner cavity 4, for generating cold by being energized under the control of the controller;

[0047] The carbon nanotube composite film 33 is extended to the outside of the cup holder body 1 for the heat dissipation surface of the refrigeration sheet 2 to dissipate heat.

[0048] Specifically, the flexible material filling layer is filled with a flexible material with a certain thickness such as memory foam or soft silicone. Both the first surface coating film and the second surface coating film are made of fabric materials, mainly playing a role of isolation. The carbon nanotube composite film is prepared on the surface of the first surface coating film.

[0049] In the adaptive-size cup holder of this embodiment, by designing a flexible heat conduction component, the beverage placed in the inner cavity can be flexibly wrapped, so as to realize the adaptive adjustment of the cup body size.

[0050] The flexible heat conduction component in this embodiment mainly utilizes the flexible, electrothermal and heat conduction characteristics of the carbon nanotube composite film;

[0051] One is to utilize the flexible characteristic of the carbon nanotube composite film to be prepared on the surface of the fabric material. As the flexible material shrinks, the flexible heat conduction component tightly adheres to the surface of the beverage in an adaptive size;

[0052] The second 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 heat can be conducted to the beverage in the inner cavity, so as to achieve the purpose of heating the liquid in the cup;

[0053] The third is to utilize the heat conduction property of the carbon nanotube composite film. Face the refrigerating surface of the refrigeration sheet towards the inner cavity, tightly attach the heat dissipation surface to the carbon nanotube composite film, and extend the carbon nanotube composite film to the outside of the cup holder body, then the heat dissipation surface of the refrigeration sheet can dissipate heat.

[0054] The carbon nanotube composite film has excellent electrical conductivity and electrothermal property. 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.

[0055] In some exemplary embodiments, two copper foils 33-1 are provided at both ends of the carbon nanotube composite film 33 as electrical connection points, which are respectively connected to the positive and negative poles of the power supply for power supply. And a temperature sensor 33-2 for collecting the temperature of the inner cavity is provided on the carbon nanotube composite film. The refrigeration sheet 2 is also pasted on the carbon nanotube composite film. This part of the structure is sandwiched between two fabric materials (the first surface coating film 32, the second surface coating film 34) to form a "sandwich" structure. The distribution of the carbon nanotube composite film, the temperature sensor, the positive and negative pole copper foils of the power supply and the refrigeration sheet on the fabric material is as Figure 4 shown. The temperature sensor 33-2, the positive and negative pole copper foils 33-1 of the power supply and the refrigeration sheet 2 are connected to the controller through wires, and the controller is uniformly controlled by an eight-bit single-chip microcomputer.

[0056] For the realization of the heating and heat preservation functions, as well as the refrigeration and cooling functions of the self - adapting size cup holder, it is achieved by utilizing the electro - thermal property, heat conductivity of the carbon nanotube composite film and the thermoelectric cooler. During actual operation, the user only needs to set the desired temperature. The controller compares the temperature set by the user with the data transmitted back by the temperature sensor, so as to judge the execution of the heating and heat preservation, refrigeration and cooling functions. Further, when the temperature set by the user is greater than the temperature detected by the temperature sensor by 10 °C, the controller drives the carbon nanotube composite film to operate at full power; when the temperature set by the user is greater than the temperature detected by the temperature sensor within 10 °C, the controller drives the carbon nanotube composite film by a method similar to the PID control method, and finally stabilizes the temperature of the cup body within the range of ±2 °C of the temperature set by the user. When the temperature set by the user is less than the temperature detected by the temperature sensor by 10 °C, the controller drives the thermoelectric cooler to operate at full power; when the temperature set by the user is less than the temperature detected by the temperature sensor within 10 °C, the controller drives the thermoelectric cooler by a method similar to the PID control method, and finally stabilizes the temperature of the cup body within the range of ±2 °C of the temperature set by the user.

[0057] In some exemplary embodiments, the self - adapting size cup holder further includes a contraction mechanism 5 disposed between the inner wall of the cup holder body 1 and the flexible material filling layer 31; the contraction mechanism 5 is used to make the flexible material filling layer 31 act to wrap or release the beverage placed in the inner cavity 4. Specifically, the contraction mechanism 5 includes a telescopic rod 51, a telescopic wall 52 and a drive motor controlled and connected to the controller; the telescopic wall 52 is disposed between the inner wall of the cup holder body 1 and the flexible material filling layer 31; the drive motor is drivingly connected to the telescopic rod 51, and the telescopic rod 51 is connected to the telescopic wall 52. In this exemplary embodiment, the telescopic wall 52 can be made of a thin stainless - steel material, which has a certain bending ability and will not change its shape after long - term and multiple uses. The two telescopic walls 52 are both located between the inner wall of the cup holder body 1 and the flexible material filling layer 31 and are oppositely arranged, and the telescopic rods 51 are correspondingly arranged on the inner wall of the cup holder body 1. When the contraction action needs to be performed, the drive motor drives the telescopic rod 51 to extend, so as to push the two telescopic walls 52 to wrap the flexible material. Since the flexible material filling has a certain thickness, it can adaptively adhere to the walls of beverage cups of different sizes. When the opening action needs to be performed, the drive motor drives the telescopic rod 51 to contract, so as to release the wrapped flexible material. It should be noted that the mechanism of the telescopic rod and the telescopic wall is covered by the first and second surface films, so this mechanical mechanism cannot be seen from the outside, ensuring the beauty of the product.

[0058] In some exemplary embodiments, the contraction mechanism can be designed as an automatic contraction mechanism, that is: a first pressure sensor 5-1 for detecting whether a drink is placed in the inner cavity 4 is provided at the bottom of the inner cavity 4; the first pressure sensor 5-1 is connected to the controller. Specifically, a second pressure sensor 5-2 can also be provided on the surface of the carbon nanotube composite film 33 facing the first surface coating 32; the second pressure sensor 5-2 is connected to the controller and is used to detect the pressure of the flexible heat-conducting component 3 wrapping the drink.

[0059] When the first pressure sensor 5-1 detects that a cup is placed, the contraction mechanism 5 automatically contracts, and the flexible heat-conducting component 3 wraps the cup. When the second pressure sensor 5-2 detects the corresponding force, it indicates that the cup has been tightly wrapped, and at this time, the contraction function of the contraction mechanism 5 is completed. When the first pressure sensor 5-1 detects that the cup is lifted, the contraction mechanism 5 will automatically open.

[0060] Embodiment 2

[0061] This embodiment provides a vehicle cup holder, which includes the adaptive-size cup holder described in Embodiment 1 provided inside the armrest box body 6.

[0062] Specifically, as Figure 5 shown, a wind duct 7 is provided inside the armrest box body 6 below the adaptive-size cup holder;

[0063] The outer bottom of the cup holder body 1 and the inner wall of the wind duct 7 are both plated with a carbon nanotube composite film, and the carbon nanotube composite film is connected to the carbon nanotube composite film of the cup holder body;

[0064] The air inlet 71 of the wind duct 7 is communicated with the air outlet of the vehicle air conditioner, and the air outlet 72 of the wind duct 7 is communicated with the vehicle chassis, so as to take away the heat derived from the heat dissipation surface of the refrigerating sheet 2 through the wind in the wind duct 7 and complete the heat dissipation of the heat dissipation surface of the refrigerating sheet 2.

[0065] The solution of this embodiment completes the heat dissipation of the refrigerating sheet through a clever structural design and a carbon nanotube composite film. Compared with the traditional solution of using a fan for heat dissipation, the heat dissipation fan is saved, and the space occupation is greatly reduced.

[0066] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, and all should be covered within the protection scope of the present invention.
