[0028] Combined with Figure 2 、 Figure 3 and Figure 4 As shown, a module mounting portion 12 is provided on the outer side of the lower end of the cup holder housing 1, a button mounting portion 13 is provided on the upper end of the side of the cup holder housing 1 away from the module mounting portion 12, a circular hole 14 axially penetrating is provided in the middle of the lower end of the cup holder housing 1, and wire harness notches 15 are respectively provided on both sides of the circular hole 14. The arrangement of the module mounting portion 12 and the button mounting portion 13 provides clear mounting positions for the control module 62 and the control button 63, facilitates installation and operation, and has a reasonable layout, which is beneficial to the compactness of the overall structure. The axially penetrating circular hole 14 and the wire harness notches 15 on both sides provide a channel for the layout of lines such as the control wire harness 61, make the routing of the lines more regular, avoid the clutter of the lines, and are also convenient for the maintenance and repair of the lines.

[0029] Among them, the control device 6 includes a control wire harness 61 arranged on the outer side of the lower end of the cup holder housing 1. A control module 62 connected to one end of the control wire harness 61 is arranged in the module mounting part 12. A control button 63 connected to the other end of the control wire harness 61 is arranged in the button mounting part 13. And a branch wire harness 64 connected to the heating component 3 is arranged on the control wire harness 61. The control wire harness 61 connects the control module 62, the control button 63 and the heating component 3, realizing effective control of the heating component 3. The user can conveniently operate the heating process through the control button 63. The control module 62 can accurately control the heating temperature and time, improving the safety and stability of heating. The setting of the branch wire harness 64 makes the connection of components such as the heating component 3 and the NTC temperature sensor 32 clearer, facilitating individual maintenance and repair of each component.

[0030] Specifically, one end of the control wire harness 61 close to the control module 62 extends to the side of the cup holder housing 1 close to the module mounting part 12. The end of the control wire harness 61 far from the control module 62 extends to the side of the cup holder housing 1 far from the module mounting part 12 and is arranged vertically upward. And a plurality of wire harness buckles 16 respectively connected to the control wire harness 61 and the branch wire harness 64 are arranged at the lower end of the cup holder housing 1. The extension direction and setting method of the control wire harness 61 make the layout of the circuit more reasonable, avoiding winding and mutual interference of the circuits, improving the safety and reliability of the circuits. The setting of the wire harness buckles 16 can effectively fix the control wire harness 61 and the branch wire harness 64, preventing the circuits from loosening or falling off, ensuring the stability of the circuit connection, and at the same time facilitating the arrangement and maintenance of the circuits.

[0031] Furthermore, the heating component 3 includes a heating film 31 arranged on the circumferential outer side of the cup holder inner liner 2. The heating film 31 is a PI heating film. The width of the heating film 31 is less than or equal to the height of the cup holder inner liner 2. An NTC temperature sensor 32 is arranged on one side of the lower end of the cup holder inner liner 2. The number of the branch wire harnesses 64 is two and they respectively correspond to the wire harness notches 15. One of the branch wire harnesses 64 is connected to the PI heating film 31, and the other branch wire harness 64 is connected to the NTC temperature sensor 32. As the heating component 3, the PI heating film has good heating performance, can quickly and evenly heat the cup holder inner liner 2, improving the heating efficiency. The NTC temperature sensor 32 can monitor the temperature of the cup holder inner liner 2 in real time. Cooperating with the control module 62, it can realize precise control of the heating temperature, avoid too high or too low temperature, and ensure the safety and stability of heating. The correspondence between the branch wire harness 64 and the wire harness notch 15 makes the connection of the circuits more orderly, facilitating installation and maintenance, and ensuring the normal operation between components.

[0032] Furthermore, there is a heat insulation gap between the cup holder outer shell 1 and the cup holder inner liner 2. The heat insulation layer 5 is arranged in the heat insulation gap. A number of support block notches 51 matching the support blocks 11 are provided on the inner side of the lower end of the heat insulation layer 5, and a number of limit seat notches 52 matching the limit seats 41 are provided on the circumferential outer side of the lower end of the heat insulation layer 5. The heat insulation gap is used for the installation of the heat insulation layer 5. The heat insulation layer 5 is in the form of PU foaming. After foaming, the heat insulation gap is filled and firmly connected to ensure airtightness, which can effectively reduce heat dissipation, extend the heat preservation time of items, and improve the user experience. The settings of the support block notches 51 and the limit seat notches 52 enable the heat insulation layer 5 to better cooperate with the support blocks 11 and the limit seats 41, ensuring the installation accuracy and stability of the heat insulation layer 5 and further enhancing the heat insulation effect.

[0033] At the same time, the cup holder inner liner 2 is made of aluminum material, and the upper end surfaces of the cup holder outer shell 1, the cup holder inner liner 2, and the heat insulation layer 5 are on the same horizontal plane. The cup holder inner liner 2 made of aluminum material has good heat conduction performance, can quickly conduct heat, and improve the heating efficiency. At the same time, the aluminum material is light in weight and corrosion-resistant, extending the service life of the cup holder inner liner 2. The upper end surfaces of the cup holder outer shell 1, the cup holder inner liner 2, and the heat insulation layer 5 being on the same horizontal plane make the appearance of the in-vehicle heating cup holder more neat and beautiful, coordinated with the overall style of the vehicle interior, and enhancing the quality sense of the product.

[0034] The principle of this embodiment is as follows:

[0035] There is a thermal insulation layer 5 between the cup holder outer shell 1 and the cup holder inner liner 2 in a foam filling manner. The thermal insulation layer 5 is filled in the thermal insulation gap, which can effectively reduce the heat dissipation to the outside. At the same time, there is a support block notch 51 on the inner side of the lower end of the thermal insulation layer 5 that matches the support block 11, and a limit seat notch 52 on the outer circumference of the lower end of the thermal insulation layer 5 that matches the limit seat 41. This design not only ensures the integrity of the thermal insulation layer 5 but also does not prevent the support block 11 and the limit seat 41 from supporting and fixing the cup holder inner liner 2, further enhancing the thermal insulation effect and enabling the beverage to maintain its heat for a long time. The control module 62 and the control button 63 in the control device 6 control the heating component 3 through the control wire harness 61 and the branch wire harness 64. The PI heating film in the heating component 3 is arranged on the outer circumference of the cup holder inner liner 2 and generates heat after being powered on. Since the cup holder inner liner 2 is made of aluminum material, and aluminum has good thermal conductivity, it can quickly transfer the heat to the beverage placed in the cup holder inner liner 2, thus realizing the heating of the beverage. The cup holder inner liner 2 can monitor the temperature of the cup holder inner liner 2 in real time through the NTC temperature sensor 32, and transmit the temperature signal to the control module 62 through the branch wire harness 64 and the control wire harness 61. When the temperature reaches the set upper limit value, the control module 62 will control to reduce or cut off the power supply to the PI heating film, so that the heating stops or the power is reduced. When the temperature is lower than the set lower limit value, the control module 62 will increase the power supply to make the PI heating film continue to heat, thereby realizing the precise control of the temperature in the cup holder inner liner 2 and keeping the beverage at an appropriate temperature.
