Description

Technical Field

[0001] The invention relates to the technical field of vehicles, and in particular to a water cup holder in a cab. Background Art

[0002] In modern vehicle design, cup holders are a basic configuration, and their functionality and convenience have received great attention and development. The early vehicle cup holders were relatively simple in design, with the main purpose of providing a space for drivers or passengers to place beverage containers to prevent them from tipping over during driving and to facilitate the driver or passenger to take them out. However, with the increasing diversification of user needs and the advancement of technology, traditional cup holders can no longer meet the growing needs of users.

[0003] As people's call for improving driving comfort becomes stronger and stronger, the demand for drinking a sip of hot water while driving in cold winter and a sip of cold water in hot summer is getting higher and higher. Currently, there are cup holders that can cool and heat. The cup holder is set at the air outlet of the air conditioner. When the air conditioner is turned on, the airflow ejected from the air outlet of the air conditioner directly acts on the beverage container on the cup holder, thereby achieving heating or cooling of the beverage in the beverage container.

[0004] However, this structure has the following disadvantages:

[0005] 1. Low heat transfer efficiency. The air conditioning airflow only exchanges heat through the contact between the air and the surface of the beverage container. Compared with direct contact heat conduction (such as semiconductor or resistance wire heating), the heat transfer efficiency is significantly reduced.

[0006] 2. Interference with air conditioning performance: The cup holder occupies the air outlet space, which will reduce the amount of air delivered by the air conditioner to other areas in the car, resulting in obstructed air circulation and uneven temperature distribution in the car.

[0007] 3. The combination of the cup holder and the air outlet may change the air flow path, causing increased wind noise at the air-conditioning outlet, affecting driving or riding comfort.

[0008] 4. Because the cup holder needs to be set at the air outlet of the air conditioner, the location of the cup holder is limited by the location of the air outlet of the air conditioner and can only be set at the location of the air outlet of the air conditioner.

[0043] The cooling system of the engine 102 usually mainly includes a radiator 100 and a water pump 101. The coolant outlet of the engine 102 is connected to the liquid inlet of the radiator 100 through a coolant pipeline. The radiator 100, the water pump 101 and the coolant inlet of the engine 102 are connected in sequence. The water pump 101 is used to drive the coolant to circulate between the engine 102 and the radiator 100. The radiator 100 is responsible for dissipating the heat generated by the engine 102 through the coolant. Therefore, the coolant in the coolant pipeline between the engine 102 and the radiator 100 carries the heat generated by the engine 102. In the prior art, this part of the heat is mostly used to provide heat to the cab.

[0044] The vehicle air conditioner includes a compressor 200, a condenser 201, an expansion device 202 and an evaporator 203 which are connected in series in sequence and form a ring loop. The refrigerant is first sucked into the compressor 200 in the form of a low-temperature and low-pressure gas. In the compressor 200, the refrigerant is compressed into a high-temperature and high-pressure gas to provide power for subsequent heat exchange. The high-temperature and high-pressure gaseous refrigerant enters the condenser 201, exchanges heat with the external air, releases heat and condenses into a liquid state. The liquid refrigerant is throttled and decompressed through the expansion valve, and the temperature and pressure drop sharply, becoming a low-temperature and low-pressure mist mixture. The low-temperature and low-pressure refrigerant enters the evaporator 203, absorbs the heat of the air in the car and evaporates into a gaseous state, thereby achieving cooling in the car, and the gaseous refrigerant is sucked into the compressor 200 again to start the next cycle. During the entire cycle, the refrigerant temperature in the refrigerant pipeline between the expansion device 202 and the evaporator 203 is low and can absorb a large amount of heat.

[0045] This embodiment provides a cab water cup holder, which utilizes the heat released by the coolant in the coolant pipeline and the heat absorbed by the refrigerant in the refrigerant pipeline to heat or cool the beverage in the cup 300. Figures 1 to 4As shown, the cab water cup holder includes a heating cup holder 11 and a first flow regulating valve 12. The heating cup holder 11 is provided with a heating cavity 1121 for accommodating the cup 300. A heating flow channel 114 is provided in the heating cup holder 11. The heating flow channel 114 is opposite to the bottom wall and / or the peripheral wall of the heating cavity 1121. The inlet of the heating flow channel 114 is connected to the coolant pipeline between the engine 102 and the radiator 100 through the first flow regulating valve 12. The outlet of the heating flow channel 114 is used to communicate with the coolant pipeline. The connection position of the first flow regulating valve 12 and the coolant pipeline is located upstream of the connection position of the outlet of the heating flow channel 114 and the coolant pipeline. When the vehicle provided with the heating cup holder 11 is started, as the temperature of the engine 102 continues to rise, the coolant temperature in the coolant pipeline between the engine 102 and the radiator 100 continues to rise. When the beverage in the cup 300 needs to be heated, the first flow regulating valve 12 is opened. Since the communication position between the first flow regulating valve 12 and the coolant pipeline is located upstream of the communication position between the outlet of the heating channel 114 and the coolant pipeline, the coolant in the coolant pipeline enters the heating channel 114 through the first flow regulating valve 12, and then flows back to the coolant pipeline from the heating channel 114. In this process, since the heating channel 114 is opposite to the bottom wall and / or the peripheral wall of the heating chamber 1121, the heat of the coolant is transferred to the cup 300 through the bottom wall and / or the peripheral wall of the heating chamber 1121, thereby heating the beverage in the cup 300. The heating cup holder 11 transfers heat in the form of contact, thereby having the advantage of high heating efficiency; the heating cup holder 11 does not need to be set at the air outlet of the air conditioner, thereby avoiding interference with the performance of the air conditioner, avoiding noise, and solving the problem of limited position setting of the heating cup holder 11.

[0046] Specifically, the cup 300 is made of a single-layer metal material, which is conducive to heating the heat on the cup holder 11 to heat the beverage through the cup 300.

[0047] Specifically, the flow resistance of the coolant in the coolant pipeline into the heating channel 114 is smaller than the flow resistance of the coolant into the radiator 100 .

[0048] Specifically, the heating channel 114 can be arranged in a serpentine shape and coiled around the bottom wall and / or the surrounding wall of the heating chamber 1121 respectively, or it can include two first heating chambers 1141 and second heating chambers 1142 that are connected in sequence, the first heating chamber 1141 is located at the bottom wall of the heating chamber 1121, and the second heating chamber 1142 is located at the surrounding wall of the heating chamber 1121.

[0049] In addition, the heating channel 114 and part of the coolant pipeline form a parallel structure, and this arrangement will not interfere with the normal operation of the cooling system of the engine 102.

[0050] Specifically, by adjusting the first flow regulating valve 12 , the flow rate of the cooling liquid entering the heating flow channel 114 can be adjusted, and the temperature of the beverage in the cup 300 can be adjusted.

In this embodiment, the heating base plate 111 and the heating sleeve 112 are divided into two independent components, and this arrangement reduces the processing difficulty of the heating cup holder 11. The heating base plate 111 and the heating sleeve 112 are fixed by means of the structure of the first clamping protrusions 1111 and the first clamping holes, thereby improving the assembly efficiency of the heating cup holder 11.

In this embodiment, after the cup 300 is placed in the heating chamber 1121, the first heating chamber 1141 is located at the bottom wall of the heating chamber 1121 and is just opposite to the cup 300, and the second heating chamber 1142 surrounds the peripheral wall of the heating chamber 1121 and is just opposite to the peripheral wall of the cup 300. The coolant enters the first heating chamber 1141 from the inlet, and then flows into the second heating chamber 1142 through the first flow channel 1143. When the second heating chamber 1142 is filled with coolant, the coolant flows back into the coolant pipeline from the outlet. This arrangement ensures that the first heating chamber 1141 and the second heating chamber 1142 can be filled with coolant, thereby improving the heating efficiency of the beverage in the cup 300.

[0053] Optionally, the outer peripheral wall of the first clamping protrusion 1111 is provided with a first annular groove; the heating cup holder 11 further includes a plurality of first annular sealing rings 113 corresponding to the first clamping protrusion 1111, the first annular sealing ring 113 is provided in the corresponding first annular groove, and the first clamping protrusion 1111 is inserted into the corresponding first clamping hole, so that the first clamping protrusion 1111 and the heating sleeve 112 clamp the first annular sealing ring 113. In this embodiment, the first annular sealing ring 113 can avoid the problem of liquid leakage in the heating flow channel 114. The sealing performance of the first heating chamber 1141 and the second heating chamber 1142 at the connection is improved.

[0054] Optionally, the first latching protrusion 1111 is a frustum structure, and the first latching hole is a conical hole. This arrangement facilitates the plug-in fit between the first latching protrusion 1111 and the first latching hole on the one hand, and on the other hand can enhance the clamping force of the heating sleeve 112 and the first latching protrusion 1111 on the first annular sealing ring 113, thereby enhancing the sealing performance of the heating channel 114.

[0055] Optionally, a heat insulating layer is provided on the outer peripheral wall of the heating cup holder 11. In this embodiment, this arrangement can prevent the heat on the heating cup holder 11 from being lost, and can also prevent the driver and passengers from being scalded. Specifically, the heat insulating layer is made by applying a heat insulating coating on the outer peripheral wall of the heating cup holder 11. In other embodiments, a heat insulating board material can also be attached to the outer periphery of the heating cup holder 11.

[0056] Alternatively, if Figures 5 to 8As shown, the cab water cup holder also includes a refrigeration cup holder 21 and a second flow regulating valve 22. The refrigeration cup holder 21 is provided with a refrigeration cavity 2121 for accommodating the cup 300. A refrigeration flow channel 214 is provided in the refrigeration cup holder 21. The refrigeration flow channel 214 is opposite to the bottom wall and / or the surrounding wall of the refrigeration cavity 2121. The inlet of the refrigeration flow channel 214 is connected to the refrigerant pipeline between the expansion device 202 of the air-conditioning system and the evaporator 203 of the air-conditioning system through the second flow regulating valve 22. The outlet of the refrigeration flow channel 214 is connected to the refrigerant pipeline. The connecting position of the second flow regulating valve 22 and the refrigerant pipeline is located upstream of the connecting position of the outlet of the refrigeration flow channel 214 and the refrigerant pipeline. In this embodiment, after the vehicle equipped with the refrigerated cup holder 21 is started, when the occupant turns on the air-conditioning system for cooling, and at the same time, the beverage in the cup 300 needs to be cooled, the second flow regulating valve 22 is opened. Since the connection position between the second flow regulating valve 22 and the refrigerant pipeline is located upstream of the connection position between the outlet of the refrigeration channel 214 and the refrigerant pipeline, the refrigerant in the refrigerant pipeline enters the refrigeration channel 214 through the second flow regulating valve 22, and then flows back to the refrigerant pipeline from the refrigeration channel 214. In this process, since the refrigeration channel 214 is opposite to the bottom wall and / or the surrounding wall of the refrigeration cavity 2121, the refrigerant absorbs the heat of the bottom wall and / or the surrounding wall of the refrigeration cavity 2121, and the cavity wall of the refrigeration cavity 2121 absorbs the heat of the cup 300, thereby cooling the beverage in the cup 300.
