Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicles, in particular to a cab cup holder. BACKGROUND

[0002] In modern vehicle design, cup holders are a basic configuration, and their functionality and convenience have received great attention and development. Early vehicle cup holder designs were relatively simple, and the main purpose was to provide a space for drivers or passengers to place beverage containers, preventing them from spilling during vehicle travel while facilitating the driver's or passenger's access. However, with the increasing diversification of user needs and technological advancements, traditional cup holders have been unable to meet the growing needs of users.

[0003] As people's demand for improving driving comfort increases, the need for a hot drink in cold winter or a cold drink in hot summer is increasing. Currently, there are cup holders that can cool and heat, which set the cup holder at the air outlet of the air conditioner. When the air conditioner is turned on, the airflow from the air conditioner outlet directly acts on the beverage container in the cup holder, thereby heating or cooling the beverage in the beverage container.

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

[0005] 1. Low heat transfer efficiency. Airflow from the air conditioner only exchanges heat through air contact with the surface of the beverage container, which significantly reduces the heat transfer efficiency compared to direct contact heat conduction (such as semiconductor or resistance wire heating).

[0006] 2. Interference with air conditioner performance. The cup holder occupies the air outlet space, reducing the amount of air delivered by the air conditioner to other areas of the vehicle, causing air circulation to be blocked, and the temperature distribution in the vehicle to be uneven.

[0007] 3. The combination of the cup holder and the air outlet may change the airflow path, causing the noise of the air outlet to increase, affecting driving or riding comfort.

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

[0009] In summary, there is an urgent need for a cab cup holder to solve the above problems. SUMMARY

[0010] The present application aims to provide a cab cup holder to solve the problems of low heat transfer efficiency, interference with air conditioner performance, noise, and limited cup holder position when heating or cooling beverages in the cup holder through the airflow from the air outlet of the cab air conditioner.

[0042] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0043] The cooling system of engine 102 typically includes a radiator 100 and a water pump 101. The coolant outlet of engine 102 is connected to the inlet of radiator 100 via a coolant pipeline. Radiator 100, water pump 101, and the coolant inlet of engine 102 are connected in sequence. Water pump 101 is used to drive the coolant to circulate between engine 102 and radiator 100. Radiator 100 is responsible for dissipating the heat generated by engine 102 through the coolant. Therefore, the coolant in the coolant pipeline between engine 102 and radiator 100 carries the heat generated by engine 102. In the prior art, this heat is often 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 to form a circular loop. Refrigerant is first drawn into the compressor 200 in the form of a low-temperature, low-pressure gas. Within the compressor 200, the refrigerant is compressed into a high-temperature, high-pressure gas, providing power for subsequent heat exchange. The high-temperature, high-pressure gaseous refrigerant enters the condenser 201, where it undergoes heat exchange with the outside air, releasing heat and condensing into a liquid. The liquid refrigerant passes through the expansion valve, undergoing throttling and pressure reduction, causing its temperature and pressure to drop sharply, turning into a low-temperature, low-pressure mist-like mixture. The low-temperature, low-pressure refrigerant enters the evaporator 203, where it absorbs heat from the air inside the vehicle and evaporates into a gaseous state, thereby cooling the vehicle interior. The gaseous refrigerant is then drawn back into the compressor 200, beginning the next cycle. Throughout the entire cycle, the refrigerant in the refrigerant pipeline between the expansion device 202 and the evaporator 203 remains at a relatively low temperature, allowing it to absorb a significant amount of heat.

[0045] This embodiment provides a cab water cup holder, which utilizes the heat released by the coolant in the coolant pipe and the heat absorbed by the refrigerant in the refrigerant pipe to heat or cool the beverage in the cup 300. Figures 1 to 4As shown, the cab water cup holder includes a heated cup holder 11 and a first flow regulating valve 12. The heated cup holder 11 is provided with a heating chamber 1121 for accommodating cups 300. A heating channel 114 is provided within the heated cup holder 11. The heating channel 114 is opposed to the bottom wall and / or peripheral wall of the heating chamber 1121. The inlet of the heating channel 114 communicates with the coolant pipeline between the engine 102 and the radiator 100 through the first flow regulating valve 12. The outlet of the heating channel 114 is used to communicate with the coolant pipeline. The connection point between the outlet of the heating channel 114 and the coolant pipeline is located upstream of the connection point between the outlet of the heating channel 114 and the coolant pipeline. When a vehicle equipped with the heated cup holder 11 is started, as the temperature of the engine 102 continues to rise, the temperature of the coolant in the coolant pipeline between the engine 102 and the radiator 100 also continues to rise. When heating the beverage in the cup 300, the first flow regulating valve 12 is opened. Since the connection between the first flow regulating valve 12 and the coolant pipeline is located upstream of the connection between the outlet of the heating channel 114 and the coolant pipeline, the coolant in the coolant pipeline passes through the first flow regulating valve 12 and enters the heating channel 114, then flows back into the coolant pipeline from the heating channel 114. During this process, since the heating channel 114 is opposite to the bottom wall and / or peripheral wall of the heating chamber 1121, the heat of the coolant is transferred to the cup 300 through the bottom wall and / or peripheral wall of the heating chamber 1121, thereby heating the beverage in the cup 300. The heated cup holder 11 transfers heat through contact, resulting in high heating efficiency. The heated cup holder 11 does not need to be located at the air outlet of the air conditioner, thereby avoiding interference with air conditioning performance and noise generation, and resolving the issue of limited placement of the heated cup holder 11.

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

[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. It can also include two first heating chambers 1141 and second heating chambers 1142 that are connected in sequence, with the first heating chamber 1141 located on the bottom wall of the heating chamber 1121 and the second heating chamber 1142 located on 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, which 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 coolant entering the heating flow channel 114 can be adjusted, thereby adjusting the temperature of the beverage in the cup 300 .

[0051] Optionally, the heated cup holder 11 includes a heating base plate 111 and a heating sleeve 112. The heating base plate 111 is provided with a plurality of first latching protrusions 1111, and one end of the heating sleeve 112 is provided with a plurality of first latching holes. The plurality of first latching protrusions 1111 are inserted into the plurality of first latching holes in a one-to-one correspondence, so that the heating base plate 111 and the heating sleeve 112 enclose a heating chamber 1121. In this embodiment, the heating base plate 111 and the heating sleeve 112 are separated into two independent components, which reduces the difficulty of manufacturing the heated cup holder 11. The heating base plate 111 and the heating sleeve 112 are fixed together by the structure of the first latching protrusions 1111 and the first latching holes, thereby improving the assembly efficiency of the heated cup holder 11.

[0052] Optionally, the heating channel 114 includes a first heating chamber 1141, a second heating chamber 1142 and a plurality of first flow channels 1143, the first heating chamber 1141 is located in the heating base plate 111, the second heating chamber 1142 is located in the heating sleeve 112, and the plurality of first flow channels 1143 are arranged one-to-one in the plurality of first clamping protrusions 1111, one end of the first flow channel 1143 is connected to the first heating chamber 1141, and the other end is located on the top wall of the first clamping protrusion 1111, the second heating chamber 1142 is connected to the first clamping hole, and the first clamping protrusion 1111 is inserted in the first clamping hole so that the other end of the first flow channel 1143 is connected to the first clamping hole, the inlet of the heating channel 114 is connected to the first heating chamber 1141, and the outlet of the heating channel 114 is connected to the second heating chamber 1142 and is located on the side of the second heating chamber 1142 away from the first heating chamber 1141. In this embodiment, after the cup 300 is placed in the heating chamber 1121, the first heating chamber 1141 is located on the bottom wall of the heating chamber 1121 and directly opposite the cup 300. The second heating chamber 1142 surrounds the peripheral wall of the heating chamber 1121 and directly opposite the peripheral wall of the cup 300. Coolant enters the first heating chamber 1141 through the inlet, 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 through the outlet. This arrangement ensures that both the first heating chamber 1141 and the second heating chamber 1142 are fully 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 comprises a plurality of first annular sealing rings 113 corresponding to the first clamping protrusions 1111, the first annular sealing rings 113 are arranged in the corresponding first annular grooves, and the first clamping protrusions 1111 are inserted into the corresponding first clamping holes so that the first clamping protrusions 1111 and the heating sleeve 112 clamp the first annular sealing rings 113. In this embodiment, the first annular sealing rings 113 can avoid the problem of liquid leakage of the heating flow channel 114. The sealing performance of the first heating cavity 1141 and the second heating cavity 1142 at the connection is improved.

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

[0055] Optionally, the outer peripheral wall of the heating cup holder 11 is provided with a heat insulation layer. In this embodiment, this arrangement can avoid the loss of heat on the heating cup holder 11, and can also avoid scalding the driver and the passenger. Specifically, the heat insulation layer is made by brushing heat insulation paint on the outer peripheral wall of the heating cup holder 11. In other embodiments, a heat insulation plate material can also be attached to the outer periphery of the heating cup holder 11.

[0056] Optionally, as 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 connection position of the second flow regulating valve 22 and the refrigerant pipeline is located upstream of the connection position of the outlet of the refrigeration flow channel 214 and the refrigerant pipeline. In this embodiment, when 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 needs to cool the beverage in the cup 300, 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 flow channel 214 and the refrigerant pipeline, the refrigerant in the refrigerant pipeline enters the refrigeration flow channel 214 through the second flow regulating valve 22, and then flows back into the refrigerant pipeline from the refrigeration flow channel 214. In this process, since the refrigeration flow channel 214 is opposite to the bottom wall and / or surrounding wall of the refrigeration cavity 2121, the refrigerant absorbs heat from the bottom wall and / or surrounding wall of the refrigeration cavity 2121, and the cavity wall of the refrigeration cavity 2121 absorbs heat from the cup 300, thereby cooling the beverage in the cup 300. The cooling cup holder 21 transfers heat by contact, thus having the advantage of high cooling efficiency; the cooling cup holder 21 does not need to be set at the air outlet of the air conditioner, thus avoiding interference with the air conditioner performance, avoiding noise, and solving the problem of limited position setting of the heating cup holder 11.

[0057] Specifically, the flow resistance of the refrigerant in the refrigerant pipeline into the refrigeration flow channel 214 is smaller than the flow resistance of the refrigerant into the evaporator 203 .

[0058] Specifically, the refrigeration channel 214 can be arranged in a serpentine shape and coiled around the bottom wall and / or the peripheral wall of the refrigeration cavity 2121, or it can include two first refrigeration cavities 2141 and second refrigeration cavities 2142 connected in sequence, the first refrigeration cavity 2141 is located on the bottom wall of the refrigeration cavity 2121, and the second refrigeration cavity 2142 is located on the peripheral wall of the refrigeration cavity 2121.

[0059] In addition, the cooling channel 214 and part of the refrigerant pipeline form a parallel structure, and this arrangement will not interfere with the normal operation of the air-conditioning refrigeration system.

[0060] Specifically, by adjusting the second flow regulating valve 22 , the flow rate of the refrigerant entering the refrigeration flow channel 214 can be adjusted, and the temperature of the beverage in the cup 300 can be adjusted.

[0061] Optionally, the refrigeration cup holder 21 includes a refrigeration base plate 211 and a refrigeration sleeve 212. The refrigeration base plate 211 is provided with a plurality of second latching protrusions 2111, and one end of the refrigeration sleeve 212 is provided with a plurality of second latching holes. The plurality of second latching protrusions 2111 are inserted into the plurality of second latching holes in a one-to-one correspondence, so that the refrigeration base plate 211 and the refrigeration sleeve 212 enclose a refrigeration cavity 2121. In this embodiment, the refrigeration base plate 211 and the refrigeration sleeve 212 are separated into two independent components, which reduces the manufacturing difficulty of the refrigeration cup holder 21. The refrigeration base plate 211 and the refrigeration sleeve 212 are fixed together by the structure of the second latching protrusions 2111 and the second latching holes, thereby improving the assembly efficiency of the refrigeration cup holder 21.

[0062] Optionally, the refrigeration channel 214 includes a first refrigeration cavity 2141, a second refrigeration cavity 2142 and a plurality of second flow channels 2143. The first refrigeration cavity 2141 is located in the refrigeration base plate 211, the second refrigeration cavity 2142 is located in the refrigeration sleeve 212, and the plurality of second flow channels 2143 are arranged in a one-to-one correspondence in the plurality of second clamping protrusions 2111. One end of the second flow channel 2143 is connected to the first refrigeration cavity 2141, and the other end is located on the top wall of the second clamping protrusion 2111. The second refrigeration cavity 2142 is connected to the second clamping hole. The second clamping protrusion 2111 is inserted into the second clamping hole so that the other end of the second flow channel 2143 is connected to the second clamping hole. The inlet of the refrigeration channel 214 is connected to the first refrigeration cavity 2141, and the outlet of the refrigeration channel 214 is connected to the second refrigeration cavity 2142 and is located on the side of the second refrigeration cavity 2142 away from the first refrigeration cavity 2141. In this embodiment, after the cup 300 is placed in the refrigeration chamber 2121, the first refrigeration chamber 2141 is located at the bottom wall of the refrigeration chamber 2121 and directly opposite the cup 300. The second refrigeration chamber 2142 surrounds the peripheral wall of the refrigeration chamber 2121 and directly opposite the peripheral wall of the cup 300. Refrigerant enters the first refrigeration chamber 2141 through the inlet, then flows into the second refrigeration chamber 2142 through the second flow channel 2143. When the second refrigeration chamber 2142 is filled with refrigerant, the refrigerant flows back into the refrigerant pipeline through the outlet. This arrangement ensures that the first refrigeration chamber 2141 and the second refrigeration chamber 2142 are fully filled with refrigerant, thereby improving the cooling efficiency of the beverage in the cup 300.

[0063] Optionally, the outer peripheral wall of the second latching protrusion 2111 is provided with a second annular groove. The refrigerated cup holder 21 further includes a plurality of second annular sealing rings 213 corresponding one-to-one with the second latching protrusions 2111. The second annular sealing rings 213 are disposed within the corresponding second annular grooves, and the second latching protrusions 2111 are inserted into the corresponding second latching holes, so that the second latching protrusions 2111 and the refrigeration sleeve 212 clamp the second annular sealing rings 213. In this embodiment, the second annular sealing rings 213 can prevent leakage in the refrigeration channel 214, thereby improving the sealing performance at the connection between the first refrigeration chamber 2141 and the second refrigeration chamber 2142.

[0064] Optionally, the second latching protrusion 2111 is a frustum structure, and the second latching hole is a conical hole.
