Description

Technical Field

[0001] This invention relates to the automotive field, and more particularly to the field of automotive refrigeration technology. Background Technology

[0002] Cup holders in vehicles are designed to hold and secure cups, keeping drinks stable and preventing spills during journeys. They offer great convenience for drivers and passengers in daily use and can even serve as an important criterion for evaluating in-vehicle storage space. Cup holders of suitable size and depth ensure optimal usability.

[0003] With the increasing popularity of cars, modern people not only demand storage capacity from their vehicles but also place higher demands on comfort. In summer, the temperature inside a car is high, and the temperature of drinks rises rapidly, preventing them from effectively cooling down. Therefore, cup holders need to not only have storage functions but also a refrigerator-like function to maintain a low temperature over a long period. Thus, designing a cup holder with a cooling function is crucial.

[0004] Some car models on the market currently utilize the Peltier effect of thermoelectric semiconductor chips. A highly efficient fan circulates air to a thermoelectric module composed of numerous semiconductor chips, which cools / heats the air before transferring the heat to a conductor for further temperature regulation. When the current is reversed, the cooling and heating directions of the semiconductors are reversed, thus achieving a switching between hot and cold states.

[0005] For example, the patent publication CN202827248U, published on March 27, 2013, entitled "A Vehicle-Mounted Cooling and Heating Cup Holder and Vehicle," discloses a cup holder comprising: an inner shell, an outer shell, and a PN junction thermocouple assembly in a sandwich structure located between the inner shell and the outer shell. This invention utilizes the Peltier semiconductor effect of semiconductor materials. The PN junction thermocouple assembly absorbs heat from the air when a positive current flows through it, producing a cooling effect; when a negative current flows through it, it releases heat, producing a heating effect, thus conveniently heating or cooling beverages as needed. However, similar refrigeration devices have complex structures and high costs, making them difficult to promote in relatively low-priced car models and hindering manufacturers' control over vehicle costs.

DETAILED DESCRIPTION

[0020] The specific embodiments of the present application will be further described below with reference to the accompanying drawings and by describing the embodiments, the shape, structure, mutual position and connection relationship between the parts, the function and working principle of each part, the manufacturing process and the operation and use method of each component involved in the specific embodiments of the present application are described in further detail, to help the skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present application.

[0021] The device is improved based on the automobile air conditioning system, the automobile air conditioning system is controlled by the air conditioning function area of the car machine, the device is overall coordinated and controlled by the car machine, the automobile air conditioning system is provided with an automobile air conditioning refrigerant circulation pipeline at present, the refrigerant is compressed by the compressor, and the compressor, the condenser 12, the expansion valve 11, the stop valve A 7 and the evaporator 10 connected in sequence along the flow direction of the refrigerant, the device has a refrigerant pipeline 5 winding the cup holder 2, the cup holder 2 is generally arranged at the automobile armrest box position, the cup holder 2 with the refrigeration function needs to pre-set a space for storing the refrigerant pipeline 5 on the outer wall, the refrigerant pipeline 5 is fixed closely to the cup holder 2 and is used for transmitting heat, the refrigerant pipeline 5 has a refrigerant outlet 3 and a refrigerant inlet 6, the refrigerant inlet 6 is connected to the inlet of the stop valve A 7 through the stop valve B 8, the refrigerant outlet 3 is connected to the inlet of the compressor, and the stop valve A 7 is also controlled by the car machine.

[0022] In order to be able to detect the working state of the cup holder 2 and the current working state of the air conditioner, the temperature sensor 4 is arranged on the surface of the cup holder 2, and the inlet pipeline of the compressor is provided with the temperature and pressure sensor 9, the temperature sensor 4 and the temperature and pressure sensor 9 are connected and output sensing signals to the car machine, the car machine collects these signals and performs overall coordinated control, the control part is not the protection content of the utility model, therefore, the specific control logic is not described in detail, the core protection content of the utility model is the cup holder 2 structure winding the refrigerant pipeline 5.

[0023] The temperature control in the water cup is achieved by controlling the air temperature in the cup holder 2. The cup holder 2 refrigeration system is coupled with the air conditioning system. When the cup holder 2 needs to be refrigerated alone, the stop valve A is closed and the stop valve B is opened. The refrigerant passes through the compressor, the condenser 12, the expansion valve 11, the stop valve B, and the cup holder 2 refrigerant pipeline 5 in turn, and then returns to the compressor. By combining the feedback signals of the cup holder 2 temperature sensor 4 and the temperature and pressure sensor 9, the opening of the expansion valve 11 is adjusted to achieve real-time control of the air temperature in the cup holder 2. When the air conditioner and the cup holder 2 are refrigerated at the same time, the stop valve A and the stop valve B are opened at the same time. The same adjustment method can meet the refrigeration needs of the passenger compartment and the cup holder 2 at the same time.

[0024] Because heat conduction requires as much contact as possible, the cup holder 2 cannot achieve good refrigeration effect if it is used with different sizes of cups by the user. Therefore, the cup holder 2 is provided with a container 1 that cooperates with the gap in the inner wall of the cup holder 2. The gap cooperation can minimize the gap between the container 1 and the cup holder 2 while ensuring that the container 1 can be easily taken out. When the container 1 is placed in the cup holder 2, the gap cooperation can basically meet the refrigeration demand, and the gap between the two is minimal. The cup holder 2 and the container 1 are almost attached, and effective heat conduction can be achieved. In order to further improve the heat conduction effect, the cup holder 2 and the container 1 are both made of aluminum alloy. The height of the container 1 is greater than the depth of the cup holder 2, which can also facilitate the taking of the container 1. The container 1 can be a cup or a bottle, and generally needs to have a lid to avoid spilling the liquid in the container 1 due to the jolt of the vehicle body.

[0025] The temperature sensor 4 on the cup holder 2 cannot accurately obtain the temperature of the liquid in the container 1. In order to more accurately control the refrigeration effect of the cup holder 2, an infrared temperature measuring instrument is arranged on the inside (bottom surface) of the lid of the container 1 to collect temperature signals downward. The temperature of the liquid in the container 1 can be obtained in real time through wireless contact. A display screen is arranged on the upper surface of the lid to connect the infrared temperature measuring instrument and display the temperature information, which is also convenient for the user to understand the refrigeration effect at any time. In addition, a wireless communication unit is arranged in the lid to communicate with the vehicle machine. The wireless communication unit connects the infrared temperature measuring instrument and obtains the collected temperature signals. For example, the signals are transmitted to the vehicle machine through Bluetooth, so that the vehicle machine knows the real-time temperature of the liquid in the container 1. A battery is arranged in the lid to supply power to the wireless communication unit, the display screen, and the infrared temperature measuring instrument. The battery can be a replaceable button cell or a lithium battery built-in the lid. Therefore, a charging port needs to be arranged on the side of the lid.

[0026] The pressure sensor is connected to the vehicle machine through a signal line and sends the collected pressure signal to the vehicle machine, so that the vehicle machine can know whether there is liquid in the container 1 and the approximate volume of the liquid. Since the container 1 (non-standard) has poor refrigeration effect at room temperature, it may even be damaged, therefore, a radio frequency reader is arranged on the bottom plate of the cup holder 2, a radio frequency chip is arranged at the bottom of the container 1, the radio frequency chip has ID information, the radio frequency reader is connected and outputs the read information to the vehicle machine, and is used for identity recognition. Only when the identification is correct, the refrigeration function can be started, otherwise, the cup holder 2 is only a regular cup holder 2 and does not have the refrigeration function.

[0027] See Figure 2 The whole system has simple structure and high safety, fully utilizes and combines the air conditioning system, and reduces energy consumption.

[0028] The above describes the present application in conjunction with the drawings, and it is obvious that the specific implementation of the present application is not limited by the above method. Any non-essential improvement or direct application of the concept and technical solution of the present application to other occasions is within the protection scope of the present application.
