[0002] With the increasing popularity of new energy vehicles, people have higher demands for them, requiring not only a comfortable riding environment but also convenient amenities for daily life. Since people frequently need to drink water or beverages while traveling, car cup holders are becoming increasingly common in car interiors. In daily beverage consumption, car owners need to heat or cool their drinks; therefore, car cup holders must have the function of heating or cooling the cups.
[0003] Current vehicle mounts for new energy vehicles typically heat or cool a cup by placing a semiconductor cooling chip at the bottom of the mount. However, this single-channel heating or cooling method has several drawbacks. First, the temperature distribution is uneven, resulting in low efficiency. Second, the energy consumption is high, which can lead to battery depletion in new energy vehicles and negatively impact the user experience. Utility Model Content

[0006] Furthermore, the bottom of the cup holder body is provided with an air outlet, the air guide extends horizontally through the upper side wall of the cup holder body, and the air outlet extends vertically through the bottom wall of the cup holder body.
[0007] Furthermore, the cup holder body includes a cup base and a cup holder, the cup base has a receiving cavity with a top opening, the cup holder is disposed in the receiving cavity, the cup placement cavity is disposed in the cup holder, and the temperature control mechanism is disposed at the bottom of the cup holder.
[0008] Furthermore, the cup holder body also includes a heat insulation layer disposed between the cup base and the cup holder, the heat insulation layer isolating the inner wall of the cup base from the outer wall of the cup holder.
[0009] Furthermore, the air outlet includes a first air outlet located at the bottom of the cup holder, the first air outlet passing through the bottom wall of the cup holder and the heat insulation layer in sequence, and connecting the cup placement cavity with the receiving cavity.
[0010] Furthermore, the inner wall of the cup holder is provided with a spiral air guide groove, which guides the airflow entering the cup cavity through the air guide port downward to the first air outlet.
[0011] Furthermore, the air outlet also includes a second air outlet located at the bottom of the cup holder, the second air outlet penetrating the bottom wall of the cup holder and communicating the receiving cavity with the outside.
[0012] Furthermore, the temperature control mechanism includes a semiconductor cooling chip disposed on the bottom wall of the cup holder and a control switch disposed on the central armrest box. The semiconductor cooling chip is used to heat or cool the water cup in the cup holder cavity, and the control switch is electrically connected to the semiconductor cooling chip to switch the current direction of the semiconductor cooling chip.
[0013] Furthermore, the first air outlet and the second air outlet are located on both sides of the semiconductor cooling chip, respectively.
[0014] Furthermore, the conduit includes a main pipe connecting the vehicle's air conditioning system to the air conditioning vent of the center console, and a branch pipe connecting the main pipe to the air vent.
[0015] The car cup holder with temperature control proposed in this utility model has the following beneficial effects:
[0016] (1) This car cup holder connects the air vent to the air conditioning vent of the center armrest box through a pipe, making use of the car's air conditioning air, so that it works in conjunction with the temperature control mechanism to heat or cool the cups loaded in the cup holder. On the one hand, the temperature distribution is more uniform, so the heating or cooling efficiency of the cups is higher; on the other hand, it can reduce the workload of the temperature control mechanism, thereby reducing the energy consumption of the temperature control mechanism and improving the user experience.
[0017] (2) The air vent of this car cup holder runs horizontally through the upper side wall of the cup holder body, and the air outlet runs vertically through the bottom wall of the cup holder body, so that the airflow entering the cup cavity through the air vent flows downward and is finally discharged from the air outlet. During this process, the airflow exchanges heat with the water cup loaded in the cup cavity, thereby heating or cooling the water cup, and the temperature distribution is more uniform, thereby improving the efficiency of heating or cooling the water cup.
[0018] (3) This vehicle cup holder has a heat insulation layer between the cup holder and the cup tray. The heat insulation layer isolates the inner wall of the cup holder from the outer wall of the cup tray. When the temperature control mechanism heats or cools the cup tray, the heat insulation layer prevents energy from spreading outward, thereby reducing energy loss, reducing the energy consumption of the temperature control mechanism, and preventing damage to other parts of the center armrest box.
[0019] (4) The inner wall of the cup holder of this vehicle cup holder is provided with a spiral air guide groove. The spiral air guide groove guides the airflow of hot or cold air, which can prolong the contact time between the airflow and the cup in the cup holder cavity and increase the heat exchange area between the cup holder cavity and the cup. This allows the hot or cold air flowing through the cup holder cavity to better heat or cool the cup in the cup holder cavity, further improving the efficiency of heating or cooling the cup and reducing the energy consumption of the temperature control mechanism.
[0020] (5) The temperature control mechanism of this car cup holder includes a semiconductor cooling chip and a control switch. The semiconductor cooling chip is installed on the bottom wall of the cup holder, and the control switch is installed on the center armrest box. The control switch is electrically connected to the semiconductor cooling chip and also electrically connected to the power supply, so that the control switch can control the current direction of the semiconductor cooling chip, thereby controlling the semiconductor cooling chip to heat or cool, and thus enabling the semiconductor cooling chip to heat or cool the water cup in the cup cavity.
[0021] (6) The first air outlet and the second air outlet of this vehicle cup holder are respectively located on both sides of the semiconductor cooling chip. After the airflow in the cup cavity exchanges heat with the water cup, it flows through the semiconductor cooling chip from the first air outlet to the second air outlet, thereby dissipating heat from the semiconductor cooling chip, thereby improving the heat dissipation performance of the semiconductor cooling chip and extending the service life of the semiconductor cooling chip.

Detailed Implementation
[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0029] Please see Figures 1-4 An embodiment of the present invention provides a car cup holder with temperature control, comprising a cup holder body 1 disposed on the center armrest box 4, a temperature control mechanism disposed at the bottom of the cup holder body 1, and an air vent 14 penetrating the side wall of the cup holder body 1; the cup holder body 1 is provided with a cup placement cavity 121, the top of the cup placement cavity 121 is open for accommodating a cup, the temperature control mechanism is used to heat or cool the cup in the cup placement cavity 121, and the air vent 14 is connected to the air conditioning vent 41 of the center armrest box 4 through a pipe 5.
[0030] In this application, the in-vehicle cup holder includes a cup holder body 1 and a temperature control mechanism. The cup holder body 1 is installed on the center armrest box 4 of the car, and the cup holder body 1 has a cup placement cavity 121 with a top opening, so that a water cup can be loaded into the cup placement cavity 121 through the top opening.
[0031] The temperature control mechanism is located at the bottom of the cup holder body 1. When the water cup is loaded in the cup cavity 121, the temperature control mechanism heats or cools the water cup to achieve temperature control of the water cup and improve the user experience.
[0032] The car cup holder also includes an air vent 14, which penetrates the side wall of the cup holder body 1 and connects the cup cavity 121 to the outside. The air vent 14 is connected to the air conditioning vent 41 of the center armrest box 4 through a pipe 5, so that when the car's air conditioning system is started, hot or cold air is delivered to the cup cavity 121 through the air vent 14, thereby heating or cooling the water cup placed in the cup cavity 121.
[0033] In practical applications, the user's need to heat or cool the cup in the cup cavity 121 is usually consistent with the need of the car's air conditioning system to heat or cool. That is, when the water cup in the cup cavity 121 needs to be heated, the car's air conditioning system is usually used to heat the car interior; when the water cup in the cup cavity 121 needs to be cooled, the car's air conditioning system is usually used to cool the car interior.
[0034] For example, in the hot summer, users usually need to cool the water cup in the cup cavity 121, and the air conditioning system turned on at this time is generally used to cool down and lower the temperature inside the car; while in the cold winter, users usually need to heat the water cup in the cup cavity 121, and the air conditioning system turned on at this time is generally used to heat up and raise the temperature inside the car.
[0035] Therefore, in this application, by utilizing the air conditioning air of the car and having it work in conjunction with the temperature control mechanism to heat or cool the water cup installed in the cup cavity 121, on the one hand, the temperature distribution is more uniform, thereby making the heating or cooling efficiency of the water cup higher; on the other hand, it can reduce the workload of the temperature control mechanism, thereby reducing the energy consumption of the temperature control mechanism and improving the user experience.
[0036] In this embodiment, an air vent 14 is provided on the upper part of the cup holder body 1. The air vent 14 extends horizontally through the upper side wall of the cup holder body 1 and is connected to the air conditioning vent 41 of the center armrest box 4 through the pipe 5. Thus, when the car's air conditioning system is started, hot or cold air is delivered to the cup cavity 121 through the air vent 14.
[0037] An air outlet is provided at the bottom of the cup holder body 1, which vertically penetrates the bottom wall of the cup holder body 1, connecting the cup-holding cavity 121 to the outside. This allows hot or cold air supplied to the cup-holding cavity 121 to flow downwards within the cavity until it is discharged from the air outlet. During this process, the hot or cold air flowing through the cup-holding cavity 121 exchanges heat with the water cups contained within it, thereby heating or cooling the water cups and ensuring a more uniform temperature distribution, thus improving the efficiency of heating or cooling the water cups.
[0038] Specifically, in this embodiment, the cup holder body 1 includes a cup base 11 and a cup holder 12. The cup base 11 has a receiving cavity 111 with a top opening, so that the cup holder 12 is placed in the receiving cavity 111 through the top opening of the receiving cavity 111. By fixing the cup base 11 to the central armrest box 4, the cup base 11 supports the cup holder 12, and the cup holder 12 is installed on the central armrest box 4.
[0039] The cup cavity 121 is located in the cup holder 12, and the temperature control mechanism is located at the bottom of the cup holder 12. When the water cup is placed in the cup cavity 121, the temperature control mechanism heats or cools the water cup in the cup cavity 121, thereby improving the user experience.
[0040] Furthermore, in this embodiment, the cup holder body 1 also includes a heat insulation layer 13. When the cup holder 12 is placed in the receiving cavity 111 of the cup base 11, the heat insulation layer 13 is placed between the cup base 11 and the cup holder 12, thus isolating the inner wall of the cup base 11 from the outer wall of the cup holder 12. Since the temperature control mechanism is located at the bottom of the cup holder 12, the temperature control mechanism first heats or cools the cup holder 12, using the energy diffused inward by the cup holder 12 to heat or cool the water cup in the cup cavity 121.
[0041] During this process, some energy diffuses outward through the cup holder 12. If the inner wall of the cup base 11 is in direct contact with the outer wall of the cup holder 12, the energy diffused outward through the cup holder 12 will heat or cool the cup base 11. On the one hand, the heated or cooled cup base 11 will damage other components of the central armrest box 4; on the other hand, it will cause this part of the energy to be lost and cannot be effectively utilized, thereby increasing the energy consumption of the temperature control mechanism.
[0042] Therefore, in this application, a heat insulation layer 13 is provided between the cup holder 11 and the cup tray 12. The heat insulation layer 13 isolates the inner wall of the cup holder 11 from the outer wall of the cup tray 12. Thus, when the temperature control mechanism heats or cools the cup tray 12, the heat insulation layer 13 prevents energy from spreading outward, thereby reducing energy loss, lowering the energy consumption of the temperature control mechanism, and preventing damage to other components of the central armrest box 4.
[0043] In this embodiment, the air outlet includes a first air outlet 15, which is disposed at the bottom of the cup holder 12 and passes through the bottom wall of the cup base 11 and the heat insulation layer 13 in sequence, thereby connecting the cup placement cavity 121 and the receiving cavity 111 through the first air outlet 15. When the car's air conditioning system is started, hot or cold air is delivered to the cup placement cavity 121 through the air guide 14.
[0044] Hot or cold air delivered to the cup-holding cavity 121 flows downward within the cavity and is discharged into the receiving cavity 111 through the first air outlet 15. During this process, the hot or cold air flowing through the cup-holding cavity 121 exchanges heat with the water cup contained in the cavity 121, thereby heating or cooling the water cup.
[0045] Furthermore, in this embodiment, the inner wall of the cup holder 12 is provided with a spiral air guide groove 122, which delivers hot or cold air to the cup cavity 121. Under the guidance of the spiral air guide groove 122, the air flows downward to the first air outlet 15 until it is discharged from the first air outlet 15.
[0046] During this process, the airflow of hot or cold air is guided by the spiral air guide groove 122, which can prolong the contact time between the airflow and the water cup in the cup placement cavity 121 and increase the heat exchange area between the cup placement cavity 121 and the water cup. This allows the hot or cold air flowing through the cup placement cavity 121 to better heat or cool the water cup in the cup placement cavity 121, further improving the efficiency of heating or cooling the water cup and reducing the energy consumption of the temperature control mechanism.
[0047] In this embodiment, the air outlet also includes a second air outlet 16, which is disposed at the bottom of the cup holder 11 and penetrates the bottom wall of the cup holder 11, thereby connecting the receiving cavity 111 to the outside through the second air outlet 16. When hot or cold air in the cup cavity 121 is discharged into the receiving cavity 111 through the first air outlet 15, it flows toward the second air outlet 16 and is finally discharged from the second air outlet 16.
[0048] Since the temperature control mechanism is located at the bottom of the cup holder 12, that is, in the space of the receiving cavity 111, the airflow after heat exchange with the water cup in the cup cavity 121, after being discharged into the receiving cavity 111 through the first air outlet 15, can dissipate heat from the temperature control mechanism at the bottom of the cup holder 12 during the process of flowing towards the second air outlet 16, thereby improving the heat dissipation performance of the temperature control mechanism, extending the service life of the temperature control mechanism, and further improving the user experience.
[0049] Furthermore, in this embodiment, the temperature control mechanism includes a thermoelectric cooler 3 and a control switch 2. The thermoelectric cooler 3 is disposed on the bottom wall of the cup holder 12, and the control switch 2 is disposed on the central armrest box 4. According to the Peltier effect, the hot and cold surfaces of the thermoelectric cooler 3 are determined by the direction of the current. Therefore, in this application, the control switch 2 is electrically connected to the thermoelectric cooler 3 and simultaneously to the power supply, enabling the control switch 2 to control the direction of the current in the thermoelectric cooler 3, thereby controlling the thermoelectric cooler 3 to heat or cool.
[0050] Since the thermoelectric cooler 3 is located on the bottom wall of the cup holder 12, when the thermoelectric cooler 3 is heated, the cup in the cup cavity 121 is heated through the cup holder 12; when the thermoelectric cooler 3 is cooled, the cup in the cup cavity 121 is cooled through the cup holder 12, so that the user can obtain the beverage with the desired taste and improve the user experience.
[0051] After the airflow exchanges heat with the water cup in the cup cavity 121, it is discharged into the receiving cavity 111 through the first air outlet 15. During the process of flowing towards the second air outlet 16, it flows through the semiconductor cooling chip 3, thereby dissipating heat from the semiconductor cooling chip 3, thereby improving the heat dissipation performance of the semiconductor cooling chip 3 and extending the service life of the semiconductor cooling chip 3.
[0052] As mentioned in the previous embodiment, the air conditioning air from the car is utilized to work in conjunction with the temperature control mechanism to heat or cool the water cup contained in the cup-holding cavity 121. In practical applications, the thermoelectric cooler 3 can be controlled by the control switch 2 to heat or cool the water cup in the cup-holding cavity 121; alternatively, the car's air conditioning system can be activated, allowing the air conditioning air to enter the cup-holding cavity 121 through the air vent 14 and exit from the air outlet, thereby exchanging heat between the air conditioning air and the water cup in the cup-holding cavity 121 to heat or cool the water cup.
[0053] A better solution is to control the thermoelectric cooler 3 to heat or cool it, and at the same time activate the corresponding heating or cooling function of the car air conditioning system, so that the air conditioning air and the thermoelectric cooler 3 work together to heat or cool the water cup installed in the cup cavity 121. This not only improves the efficiency of heating or cooling the water cup, but also reduces the workload of the thermoelectric cooler 3, reduces the energy consumption of the thermoelectric cooler 3, and thus improves the user experience.
[0054] During this process, the airflow from the first air outlet 15 to the second air outlet 16 can also dissipate heat from the thermoelectric cooler 3, thereby further improving the heat dissipation performance of the thermoelectric cooler 3 and extending its service life.
[0055] Furthermore, in this embodiment, the first air outlet 15 and the second air outlet 16 are respectively disposed on both sides of the thermoelectric cooler 3, so that the airflow after heat exchange with the water cup in the cup cavity 121 flows through the thermoelectric cooler 3 from the first air outlet 15 to the second air outlet 16, thereby better dissipating heat from the thermoelectric cooler 3, thereby improving the heat dissipation performance of the thermoelectric cooler 3 and extending the service life of the thermoelectric cooler 3.
[0056] In this embodiment, the pipe 5 includes a main pipe 51 and a branch pipe 52. The main pipe 51 connects the car's air conditioning system to the air conditioning vent 41 of the center armrest box 4, and the branch pipe 52 connects the main pipe 51 to the air duct 14. Thus, when the car's air conditioning system starts the corresponding heating or cooling function, a portion of the air conditioning airflow passes through the main pipe 51 and is discharged from the air conditioning vent 41 of the center armrest box 4 to heat or cool the interior of the car.
[0057] Another portion of the air conditioning air flows through the main pipe 51 and the branch pipe 52, then flows into the cup-holding cavity 121 through the air guide 14, and is then discharged from the air outlet at the bottom of the cup-holding cavity 121. During this process, the air conditioning air works in conjunction with the semiconductor cooling chip 3 to heat or cool the water cup loaded in the cup-holding cavity 121, thereby improving the efficiency of heating or cooling the water cup, reducing the workload of the semiconductor cooling chip 3, reducing the energy consumption of the semiconductor cooling chip 3, and thus improving the user experience.
