Description

Technical Field

[0001] The present invention discloses a wireless charging and heating water cup system and a control method, belonging to the technical field of water cup heating. Background Art

[0002] When traditional in-vehicle heating water cups use wired charging technology, many drawbacks are exposed. Traditional in-vehicle heating water cups rely on charging cables to connect to the power source. Each time they are used, the charging cable needs to be inserted into the charging interface of the water cup, and then unplugged after use. During driving, the vehicle jolts, and the plugging and unplugging operations are not only inconvenient but also may distract the driver's attention, posing a safety hazard. The length of the charging cable is limited, greatly restricting the placement position of the water cup. If the distance between the water cup and the in-vehicle power interface is far, normal charging and heating cannot be carried out, seriously affecting the user experience. After being used for a period of time, the charging cable is prone to tangling and knotting, messily scattered in the vehicle, making the interior space of the vehicle appear chaotic and destroying the overall cleanliness and aesthetics of the vehicle interior. In order to set up the charging interface, the appearance design of the water cup has to be compromised, with an interface opened on the cup body or the bottom of the cup, destroying the original overall beauty of the water cup and may also cause dust and dirt to accumulate due to the gap at the interface, affecting the cleanliness and hygiene of the water cup.

[0003] Frequent plugging and unplugging of the charging cable will wear out the metal contacts of the charging interface of the water cup, resulting in poor contact, affecting the charging and heating functions, and shortening the service life of the water cup. In addition, the charging interface is exposed for a long time, prone to water ingress and dust ingress, causing faults such as short circuits. During daily use, the charging cable is easily bent and pulled, resulting in internal wire breaks or insulation layer damage, not only affecting normal use but also posing a risk of electric leakage.

Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

Therefore, it should not be construed as a limitation to the present invention.

[0021] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "mounted", "connected", "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0022] As Figure 1 shown, the first embodiment of the present invention provides a wireless charging and heating water cup system on the basis of the prior art, including: an energy transmitting end, which is arranged at the in-vehicle water cup holder, and the energy transmitting end is electrically connected to the vehicle power supply, and is used to convert the direct current provided by the vehicle into high-frequency alternating current of a preset frequency and radiate electromagnetic waves outward; an energy receiving end, which is arranged at the inner bottom of the non-metallic electric heating water cup, and the energy transmitting end is used to receive electromagnetic waves and convert the received electromagnetic wave electric energy into stable direct current; a heating component, which is arranged at the inner bottom of the non-metallic electric heating water cup, and the heating component is electrically connected to the energy receiving end; a control module, which is arranged inside the energy receiving end, and the control module is electrically connected to the energy transmitting end; a temperature sensor, which is arranged at the inner bottom of the non-metallic electric heating water cup, and the temperature sensor is wirelessly connected to the control module, and the temperature sensor is used to obtain and monitor the water temperature and feedback it to the control module; the control module is used to receive the water temperature, compare the water temperature with a preset temperature to obtain a comparison result, and execute a water cup heating strategy based on the comparison result.

[0023] In this embodiment, the wireless charging technology is adopted. There is no need to use a charging cable to connect the water cup and the power supply. Just place the water cup on the in-vehicle water cup holder to charge and heat, which is convenient for users and improves the convenience of use. The system does not need to set a charging interface on the water cup, making the appearance of the water cup more concise and beautiful, and the design at the in-vehicle water cup holder is more tidy, and the overall beauty of the vehicle interior will not be affected by messy wires. By arranging the temperature sensor at the inner bottom of the water cup, the water temperature can be monitored in real time and accurately, and the temperature signal is wirelessly transmitted to the control module. The control module compares and judges according to the preset temperature value and the actually measured temperature, so as to accurately control the working state of the heating component and keep the water in the water cup at the temperature expected by the user.

[0024] Furthermore, an overcurrent protection module is added to monitor the circuit current in real time. When the current exceeds the set threshold, the power supply is automatically cut off to prevent safety accidents caused by excessive current. An intelligent power adjustment chip is adopted to dynamically adjust the transmission power according to the signal fed back by the energy receiving end, which can not only ensure the charging efficiency but also avoid energy waste. The outer shell is made of fireproof and high-temperature resistant engineering plastic material to reduce the fire hazard. A non-slip pad is designed on the surface of the cup holder to prevent the cup from shaking when placed and ensure the alignment accuracy between the energy transmitting end and the receiving end.

[0025] In an exemplary embodiment, a voltage stabilizing and filtering circuit is built in the energy receiving end to stably output direct current. It further stabilizes the output direct current to provide a pure power supply for the heating component and the control module. The outer shell of the energy receiving end is made of waterproof and insulating materials to avoid short-circuit faults caused by water leakage from the cup. The setting of the voltage stabilizing and filtering circuit can effectively suppress the fluctuation of the input voltage and the interference of noise. For the heating component, the stable direct current can ensure that its heating power is constant, avoid uneven heating caused by unstable voltage, and thus improve the heating efficiency. For example, it can make the water in the cup evenly heated and avoid the phenomenon of local overheating or overcooling. For the control module, the stable power supply can enable it to accurately receive and process signals from components such as temperature sensors, make correct instructions, and ensure the stable and reliable operation of the entire system.

[0026] Furthermore, the heating component adopts graphene heating film material. Graphene has extremely high thermal conductivity and can quickly convert electrical energy into heat energy to achieve rapid temperature rise. A water cup using graphene heating film can heat the water to the set temperature in a short time, saving the user's waiting time. The graphene heating film can achieve uniform heating and avoid the situation of local overheating or overcooling that may occur in traditional heating methods. This helps to ensure the consistency of the water temperature and improve the user experience.

[0027] In this embodiment, the temperature sensor includes multiple temperature sensors, and each temperature sensor is provided with a self-calibration circuit. The self-calibration circuit is used to periodically compare and adjust the sensor output according to the preset standard temperature value. The self-calibration circuit can periodically compare the output of the sensor with the preset standard temperature value to timely detect and correct the measurement errors caused by component aging and environmental changes. For example, after long-term use, the sensitivity of the temperature sensor may decrease, resulting in deviation of the measurement data. The self-calibration circuit can adjust the output of the sensor in real time by comparing with the standard temperature value to ensure that the measured water temperature data is always accurate. The multiple temperature sensors are distributed at different positions on the bottom of the water cup to monitor the water temperature in different areas of the water cup. The self-calibration circuits of these sensors work simultaneously, which not only ensures the accuracy of the data of each sensor but also can more comprehensively and accurately reflect the actual water temperature in the water cup by comprehensively analyzing the temperature data at multiple positions.

[0028] The second embodiment of the present invention provides a control method for a wireless charging and heating water cup system on the basis of the first embodiment. The specific steps are as follows:

[0029] The control module receives the water temperature, compares the water temperature with the preset temperature to obtain a comparison result, and executes a water cup heating strategy based on the water temperature. The water cup heating strategy includes: obtaining the current vehicle interior temperature and the heating target temperature of the air conditioning system control unit; determining the heating gear based on the current vehicle interior temperature and the heating target temperature of the air conditioning system control unit, and sending a heating instruction to the energy transmitting end based on the heating gear. The energy transmitting end executes corresponding operations based on the heating instruction.

[0030] By comparing the real-time water temperature with the preset temperature, the system can accurately judge the water temperature state. Once the water temperature is lower than the preset value, heating is quickly started, and when it is higher than the preset value, it is appropriately regulated to ensure that the water in the cup always maintains the temperature expected by the user. Whether the user wants to drink hot tea or warm water, it can be easily satisfied. For example, when the user presets the water temperature to 40 °C, the system can adjust the heating strategy in real time based on this setting to ensure that the water temperature is stable at about 40 °C.

[0031] Taking into account the current vehicle interior temperature and the heating target temperature of the air conditioning system control unit makes the adjustment of the water cup heating gear match the actual vehicle interior environment. When the vehicle interior is cold in winter, the heating speed of the water cup is accelerated so that the user can drink hot water to warm up as soon as possible; when the vehicle interior temperature is relatively high in summer, the heating speed is slowed down to avoid too high water temperature, comprehensively improving the user experience.

[0032] Accurate water temperature monitoring and real-time heating regulation reduce the risk of equipment failure caused by improper temperature control. The system can dynamically adjust the heating instruction according to the changes in water temperature and vehicle interior environment, avoiding the long-term high-load operation or frequent start-stop of the heating components, extending the service life of equipment such as heating components and energy transmitting ends, reducing maintenance costs, and ensuring the stable and reliable operation of the system.

[0033] The design of this control strategy is closely integrated with the existing in-vehicle air conditioning system, has strong compatibility, and is convenient for integrated application in the in-vehicle systems of different vehicle models. In addition, the system also reserves space for subsequent function expansion. In the future, it can be conveniently connected to more in-vehicle sensors or control units to further improve the intelligent level of the system.

[0034] Further, determining the heating gear based on the current vehicle interior temperature and the heating target temperature of the air conditioning system control unit includes: determining the temperature difference based on the current vehicle interior temperature and the heating target temperature of the air conditioning system control unit; determining the heating gear based on the temperature difference.

[0035] By calculating the difference between the current in-vehicle temperature and the heating target temperature of the air conditioning system control unit, the system can keenly sense the temperature change trend inside the vehicle. When the difference is large, it indicates that the in-vehicle temperature is quite different from the desired temperature and the environment is relatively cold or hot. At this time, the heating gear of the water cup is adjusted upward or reasonably regulated to quickly adjust the water temperature to an appropriate state, ensuring that users can obtain beverages with just the right temperature in different in-vehicle environments. For example, in the cold winter, the in-vehicle temperature is low, and the set heating target of the air conditioner is high. The system will increase the heating gear of the water cup so that users can drink hot water for warmth as soon as possible.

[0036] In an exemplary embodiment, based on the temperature difference, the system determines the heating gear according to the following refined logic: The system first collects the current in-vehicle temperature and the heating target temperature of the air conditioning system control unit in real time and calculates the difference between the two.

[0037] When the temperature difference is less than or equal to A °C: It means that the in-vehicle temperature is close to the target temperature set by the air conditioner and the ambient temperature is relatively stable. At this time, the system sets the heating gear to the first heating gear. This gear uses a relatively low power for heating to maintain the water temperature in the water cup within an appropriate range, avoiding energy waste caused by overheating, and at the same time preventing the water temperature from being too high and affecting the taste of the beverage.

[0038] When the temperature difference is greater than A °C and less than or equal to B °C: It indicates that there is a certain gap between the in-vehicle temperature and the target temperature, and the environment is in a medium adjustment state. The system will automatically raise the heating gear to the second heating gear. At this gear, the heating power is moderately increased, which can ensure that the water in the water cup can reach and maintain an appropriate temperature relatively quickly, and will not cause a significant increase in energy consumption due to too high power.

[0039] When the temperature difference is greater than B °C: It means that the gap between the in-vehicle temperature and the target temperature set by the air conditioner is large, and the ambient temperature needs to be adjusted urgently. The system quickly switches the heating gear to the third heating gear and operates at the maximum power to accelerate the water temperature increase speed to meet the urgent needs of users for hot or cold drinks in cold or hot environments.

[0040] It is worth emphasizing that as key thresholds, A and B can be flexibly set according to the space size of different vehicle models, the heating / cooling efficiency of the air conditioner, and the usage habits of users during the system design stage. At the same time, the specific heating powers of the first, second, and third heating gears will also be precisely matched and optimized through a large number of experiments and simulation tests to ensure that the system can operate stably and efficiently under various working conditions.

[0041] In this embodiment, the system can automatically and accurately adjust the heating gear of the water cup according to the real-time temperature environment inside the vehicle, ensuring that users can quickly obtain beverages with appropriate temperatures in different in-vehicle environments. This intelligent adjustment mechanism avoids the cumbersome operation of manual adjustment by users, greatly improving the convenience and comfort of use.

[0042] The system reasonably distributes the heating power through accurate temperature difference judgment, avoiding unnecessary energy waste. When the in-vehicle temperature is close to the target temperature, low-power heating is adopted; while when the temperature difference is large, the heating power is increased, thus realizing the efficient utilization of energy and reducing the energy consumption cost of the vehicle.

[0043] Effectively extend the service life of the device: The reasonable switching of the heating gear reduces the frequent start-stop and long-term high-load operation of the heating components, reduces the wear degree of the device, extends the service life of devices such as the heating components and the energy emission end, reduces the maintenance and replacement frequency of the device, and ensures the long-term stable operation of the system.

[0044] This strategy can be easily integrated into various in-vehicle heating water cup systems, having good compatibility and adaptability. In addition, its modular design concept provides a broad space for the function expansion of the system, facilitating the access to more in-vehicle environment parameters or user personalized requirements in the future, and further improving the intelligent level of the system.

It can be fully applied to various fields suitable for the present invention. For those familiar with the field, additional modifications can be easily achieved.
