Detailed implementation manners

[0055] The preferred implementation manners of the present invention will be described in detail below with reference to the accompanying drawings.

[0056] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. 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.

[0057] The expression of "including" elements is an "open" expression, which only means that there are corresponding components or steps, and should not be construed as excluding additional components or steps.

[0058] In order to achieve the purpose of the present invention, in some embodiments of the heating and cooling cup holder, to achieve the above purpose, as Figure 1 and 2 shown, the heating and cooling cup holder is a vehicle-mounted cup holder, which includes: a cup holder housing 1 and two groups of cup holder assemblies 2 (the driver's seat cup holder assembly and the co-driver's seat cup holder assembly respectively) placed in the cup holder housing 1.

[0059] Each group of cup holder assemblies 2 includes: a cup holder body 21, an internal radiator 22 arranged on the inner wall of the cup holder body 21, an internal temperature sensor (not shown in the figure) arranged on the internal radiator 22, a semiconductor refrigeration sheet 23 arranged on the outside of the bottom of the cup holder body 21, an external radiator 24 arranged on the outside of the bottom of the semiconductor refrigeration sheet 23, an external temperature sensor (not shown in the figure) arranged on the external radiator 24, a regulation button 25 with a backlight, and a control circuit. The regulation button 25 is installed on the cup holder housing 1.

[0060] The control circuit is electrically connected to the internal temperature sensor of the cup holder, the external temperature sensor of the cup holder, the regulation button 25, and the thermoelectric cooler 23 respectively, and is used to switch the heating or cooling function of the thermoelectric cooler 23 in the corresponding cup holder assembly 2 according to the temperatures detected by the internal temperature sensor of the cup holder, the external temperature sensor of the cup holder, and the level of the regulation button 25.

[0061] The regulation button 25 with a backlight can adopt an integrated button, and different colors can be used to represent the cooling / heating state and the temperature state.

[0062] In the present invention, heat is transferred to the drink in the cup through the internal radiator 22 of the cup holder. In some embodiments, a sponge heat insulation layer wrapped around the periphery of the cup holder body 21 effectively reduces the loss of heat to the outside.

[0063] Further, on the basis of the above embodiments, each group of cup holder assemblies 2 further includes: a clamping plate 26, the clamping plate 26 is installed inside the cup holder housing 1, the clamping plate 26 is fixedly connected to the cup holder housing 1, and a limiting groove 28 formed by a plurality of limiting protrusions 27 is installed on the upper surface of the clamping plate 26, and the limiting groove 28 is used to limit the external radiator 24 of the cup holder.

[0064] Adopting the above preferred solution, in a bumpy vehicle driving environment, the clamping plate 26 can ensure that the external radiator 24 of the cup holder and the thermoelectric cooler 23 maintain a tightly fitting state.

[0065] Further, on the basis of the above embodiments, each group of cup holder assemblies 2 further includes: a wind guiding assembly, and the wind guiding assembly is installed inside the cup holder housing 1;

[0066] The wind guiding assembly includes: a wind guiding plate 29 and a circulation fan (not shown in the figure).

[0067] Adopting the above preferred solution, the wind guiding effect is good. The wind guiding plate 29 is used to make air enter from the air inlets 31 on both sides of the cup holder housing 1, and then under the action of the circulation fan, exhaust air to the outside of the cup holder through the air outlets 32 of the wind guiding plate 29.

[0068] Further, on the basis of the above embodiments, the control circuit includes:

[0069] A cooling and heating switching circuit, which is used to switch the cooling or heating function of the thermoelectric cooler 23;

[0070] A PWM power adjustment circuit, which is used to adjust the PWM duty cycle to change the heating or cooling power of the thermoelectric cooler 23;

[0071] An RBG full-color circuit, which is used to switch the backlight of the regulation button 25;

[0072] The temperature sampling circuit is used to detect the temperature collected by the temperature sensor inside the tray and the temperature sensor outside the tray.

[0073] The present invention starts the cooling or heating function in a time-sharing manner according to the adjustable power of the PWM duty cycle.

[0074] like Figure 3 As shown, the cooling and heating switching circuit uses a relay as a switch to control the cooling and heating of the semiconductor refrigeration plate 23, and controls the power of the semiconductor refrigeration plate 23 by turning on and off the MOS tube.

[0075] During cooling, COOL1 is set high and HEAT1 is set low. Pin 1 of relay TEC1 is connected to VBAT, and pin 2 is connected to the MOS transistor. Channel 1 PWM is activated, the MOS transistor is turned on, and pin 2 of relay is grounded. This completes the circuit and semiconductor cooler 23 begins cooling. The microcontroller adjusts the duty cycle of PWM_POW1 based on the real-time temperatures detected by the external and internal temperature sensors, changing the on-time of the MOS transistor and controlling the power of semiconductor cooler 23. A larger PWM duty cycle increases the MOS transistor's on-time and the cooler's power.

[0076] When heating, set COOL1 to a low level and HEAT1 to a high level. At this time, relay pin 1 is connected to the MOS tube, and pin 2 is connected to VBAT. Channel 1 PWM is turned on, the MOS tube is turned on, relay pin 1 is grounded, the circuit is connected, and the semiconductor refrigeration plate 23 starts heating. The microcontroller adjusts the duty cycle of PWM_POW1 according to the real-time temperature detected by the external and internal temperature sensors, changes the connection time of the MOS tube, and controls the power of the semiconductor refrigeration plate 23. It is worth noting that, if Figure 4 As shown in the figure, the control logic of channel 1 and channel 2 is the same, but the timing of channel 1 and channel 2 is different. Dead time is placed during the PWM operation period of channel 1 and the PWM operation period of channel 2 to ensure that the PWM pulse widths of channel 1 and channel 2 do not work at the same time.

[0077] like Figure 5 As shown in the figure, the RBG full-color circuit consists of two RGB lights and their circuits. The microcontroller controls the on and off of the two LED lights through the SEL_CH1 and SEL_CH2 pins. When SEL_CH1 is turned on, the RGB1+ pin of LED1 is connected to a high level. The microcontroller controls the on and off of RBG_R, RGB_B, and RGB_G by outputting PWM waveforms to PWM_R, PWM_B, and PWM_G, thereby controlling the on and off of the red, blue, and green colors of the LED lights. Different colors are displayed by the combination of the three colors.

[0078] When starting refrigeration, the RGB light flashes blue. When the temperature is lower than a certain temperature value (e.g., 4°C), the RGB light stays on blue constantly. When starting heating, the RGB light flashes red. When the temperature is higher than a certain temperature value (e.g., 55°C), the RGB light stays on red constantly.

[0079] Such as Figure 6 As shown, the temperature sampling circuit is used to detect the temperatures collected by the inner tray temperature sensor and the outer tray temperature sensor.

[0080] It should be noted that since the present invention has two groups of cup holder assemblies 2, four temperature sensors and four sampling points HSK1_OUT, HSK1_IN, HSK2_OUT, and HSK2_IN are adopted. The single-chip microcomputer reads the voltage change situation of the sampling points and converts it into an ADC value to calculate the temperature data. The single-chip microcomputer reads the sampling points controlled by SEL_CH1 and SEL_CH2. When SEL_CH1 is at a high level and SEL_CH2 is at a low level, the single-chip microcomputer reads the temperatures of HSK2_OUT and HSK2_IN. When SEL_CH1 is at a low level and SEL_CH2 is at a high level, the single-chip microcomputer reads the temperatures of HSK2_IN and HSK2_OUT. The four temperature sampling circuits on the inner radiator and the outer radiator on the cup holder side of Channel 1 and Channel 2 are grouped with the inner side and the outer side of Channel 1 as one group, and the inner side and the outer side of Channel 2 as one group. During sampling, Channel 1 or Channel 2 is selected through the channel selection pin, and different groups are switched to sample the temperature analog quantity at intervals of 1 mS.

[0081] The present invention can simultaneously detect the temperatures of the inner radiator 22 and the outer radiator 24 of the two channels of the tray, preventing the body temperature from being too high.

[0082] The present invention also discloses a control method for controlling a cooling and heating cup holder, including:

[0083] After the cooling and heating cup holder is powered on, the backlight of the regulation button 25 presents white. The cooling and heating cup holder changes the heating or refrigeration power of the semiconductor refrigeration sheet 23 by adjusting the PWM duty cycle;

[0084] When the regulation button 25 is pressed for the first time, the corresponding cup holder assembly 2 enters the refrigeration mode, the backlight state changes to blue and enters the flashing state. The outer tray temperature sensor and the inner tray temperature sensor detect the outer tray temperature T t1 and the inner tray temperature T t2 ,

[0085] If the outer tray temperature T t1 is higher than the highest temperature threshold T max1 (e.g., 50°C), then it enters the forced refrigeration mode, and the PWM duty cycle is adjusted to D1 (e.g., 48%). If the outer tray temperature T t1 is lower than the second highest temperature threshold T’ max1When it is at a certain temperature (e.g., 48°C), it enters the normal refrigeration mode, and the PWM duty cycle is adjusted to D2 (e.g., 20%);

[0086] If the temperature T inside the tray t2 is lower than the lowest temperature threshold T min1 (e.g., 4°C), the backlight becomes constantly blue, enters the weak refrigeration mode, and the PWM duty cycle is adjusted to D3 (e.g., 5%). If the temperature T inside the tray t2 is higher than the sub-lowest temperature threshold T' min1 (e.g., 50°C), it enters the normal refrigeration mode, and the PWM duty cycle is adjusted to D2 (e.g., 20°C), where D1 > D2 > D3;

[0087] When the control button 25 is pressed again, the corresponding cup holder assembly 2 enters the heating mode, the backlight status changes to red and enters the flashing state, and the external tray temperature sensor and the internal tray temperature sensor continuously detect the external tray temperature T t1 and the internal tray temperature T t2 ,

[0088] If the external tray temperature T t1 is lower than the lowest temperature threshold T min2 (e.g., 4°C), it enters the forced heating mode, and the PWM duty cycle is adjusted to D4 (e.g., 48%). If the external tray temperature T t1 is higher than the sub-lowest temperature threshold T' min2 (e.g., 20°C), it enters the normal heating mode, and the PWM duty cycle is adjusted to D5 (e.g., 20%);

[0089] If the internal tray temperature T t2 is higher than the highest temperature threshold T max2 (e.g., 50°C), it enters the weak heating mode, and the PWM duty cycle is adjusted to D6 (e.g., 5%). If the internal tray temperature T t2 is lower than the sub-highest temperature threshold T' max2 (e.g., 50°C), it enters the normal heating mode, and the PWM duty cycle is adjusted to D5 (48%), where D4 > D5 > D6;

[0090] When the control button 25 is pressed again, the backlight becomes constantly white, and the semiconductor refrigeration chip 23 stops heating or refrigerating.

[0091] As Figure 7 shown, in order to further optimize the implementation effect of the present invention, in some other embodiments, the other characteristic technologies are the same, except that the clamping plate 26 is slidably connected to the cup holder housing 1, and the clamping plate 26 can move up and down in the vertical direction.

[0092] With the above preferred solution, the clamping plate 26 moves up and down to adapt to different cup types.

[0093] Further, a plurality of guiding columns 41 are installed inside the cup holder housing 1. The guiding columns 41 pass through the through holes of the clamping plate 26, and the clamping plate 26 can move up and down along the guiding columns 41.

[0094] Further, the cup holder body 21 is of a split structure, which includes: an upper fixed cup holder part 211 and a lower sliding cup holder part 212. The upper fixed cup holder part 211 is fixedly connected to the cup holder housing 1, and the lower sliding cup holder part 212 and the upper fixed cup holder part 211 can relatively slide in the vertical direction.

[0095] Further, each group of cup holder assemblies 2 further includes: a cup holder adjustment assembly, and the cup holder adjustment assembly is installed inside the cup holder housing 1;

[0096] The cup holder adjustment assembly includes: a height sensor 42 arranged on the upper fixed cup holder part 211, an electromagnet 43 installed on the inner side of the cup holder housing 1, and a magnetorheological fluid 44. The magnetorheological fluid 44 is placed in the cavity of the clamping plate 26;

[0097] The height sensor 42 is used to detect the height of the cup placed in the cup holder body 21, and the height sensor 42 and the electromagnet 43 are respectively electrically connected to the control circuit.

[0098] The present invention adopts a telescopic split-type cup holder body 21 and a cup holder adjustment assembly to adapt to different cup types.

[0099] Specifically, place the cup in the cup holder body 21. The height sensor 42 detects the height of the cup and sends it to the control circuit. If the control circuit detects that it is lower or higher than the threshold, it adjusts the magnitude and direction of the current flowing through the electromagnet 43, so that under the action of the magnetic field, the magnetorheological fluid 44 drives the clamping plate 26 to drive the sliding cup holder part to slide up or down a certain distance to adapt to the height of different cups and improve the user experience.

[0100] The present invention discloses a warm and cold cup holder and its control method, which has the following beneficial effects:

[0101] First, the present invention adopts a multi-channel setting, and can simultaneously control the heating or cooling functions of multiple groups of cup holder assemblies.

[0102] Second, the present invention adopts an external temperature sensor of the cup holder and an internal temperature sensor of the cup holder to detect the external temperature and the internal temperature of the cup holder in real time, and based on the collected real-time temperature, regulates the heating or cooling power of the cup holder assembly, with good temperature control effect and more energy-saving and environmental protection.

[0103] Third, the present invention uses a control button with a backlight for display, which improves the user experience.

[0104] Fourth, the present invention adopts an adjustable structure, so that the cup holder is applicable to cups of different heights, which improves the user experience.
