[0036] The technical solutions of this utility model will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0037] like Figure 1-3 As shown, the present invention provides a central armrest area refrigeration space integration system, which includes a central armrest 1, a storage drawer 2, an armrest board 3, and an evaporator 4.

[0038] The central armrest 1 is fixed in the aisle between the front seats of the car. The rear end of the armrest 1 has a refrigerator compartment 10101. The top of the refrigerator compartment 10101 has an item access opening 1011, and the rear end has a drawer entrance 1012. The storage drawer 2 is pulled out and installed in the refrigerator compartment 10101 through the drawer entrance 1012 for rear passengers to access items. The armrest 3 is opened and closed on the item access opening 1011 for front passengers to access items in the storage drawer 2. The evaporator 4 is located on the front side of the refrigerator compartment 101 and is connected to the refrigerant circulation loop of the vehicle's air conditioning system through pipes to cool the refrigerator compartment 10101.

[0039] The aforementioned structure integrates the refrigerator compartment 10101 into the center armrest 1, ensuring the refrigeration function is completed during vehicle manufacturing, eliminating the need for post-installation by the user and enhancing product integration and user experience. Simultaneously, front-seat occupants can access items in the storage drawer 2 via the top access port 1011, while rear-seat occupants can pull out the storage drawer 2 via the rear drawer entrance 1012 to move items back for easy retrieval. This structure achieves independent operation for both front and rear occupants without interference, further improving the user experience.

[0040] The vehicle air conditioning system includes core components such as a compressor, condenser, electronic expansion valve, and evaporator. Its refrigerant circulation loop is connected to the evaporator 4 in this invention via pipes. When the vehicle air conditioning system operates in cooling mode, the refrigerant is compressed by the compressor and enters the condenser to dissipate heat. It then passes through the electronic expansion valve for throttling and pressure reduction before finally flowing into the evaporator 4, achieving continuous cooling of the refrigerator compartment 10101 during the heat absorption process. Its specific structure and principle can be found in the technical solution of a vehicle refrigerator proposed in invention application CN116653737A, and will not be elaborated here.

[0041] In the aforementioned integrated system of refrigerated space in the central armrest area, the front or rear end of the armrest panel 3 is connected to the top of the central armrest 1 via a hinge. This structure allows the armrest panel 3 to open and close flexibly, making it convenient for front-seat passengers to quickly open and retrieve refrigerated items. At the same time, when closed, it helps maintain the low-temperature environment inside the refrigerated compartment 101, improving overall ease of use and heat preservation performance.

[0042] Furthermore, a sealing gasket is provided on the bottom surface of the armrest panel 3 to seal the gap between the armrest panel 3 and the central armrest 1, thereby improving the sealing effect and preventing cold air from easily escaping.

[0043] Furthermore, the top surface of the armrest panel 3 is provided with a soft padding layer to improve the comfort of the occupants' elbows.

[0044] In the aforementioned integrated refrigerated space system in the central armrest area, the side of the storage drawer 2 is connected to the inner wall of the refrigerator compartment 10101 via drawer slides. Alternatively, the side of the storage drawer 2 can be directly slidably connected to the side wall of the drawer entrance 1012 and the side wall of the refrigerator compartment 10101. Both connection methods allow the storage drawer 2 to be pulled out forward and backward, making it easy for rear passengers to retrieve refrigerated items.

[0045] Furthermore, after the storage drawer 2 is pushed into the refrigerator compartment 10101, its front end is magnetically fixed to the front end of the refrigerator compartment 10101, and its side is magnetically fixed to the side wall of the drawer entrance 1012.

[0046] Magnetic metal sheets are installed at the front end of the refrigerator compartment 10101 and on the side wall of the drawer entrance 1012. Correspondingly, magnets are installed at the front end and side of the storage drawer 2. The magnets and magnetic metal sheets are magnetically attracted to each other, thus magnetically fixing the storage drawer 2. This magnetic fixing method not only effectively prevents the drawer from accidentally sliding out due to vibration or bumps during vehicle operation, ensuring the safety of passengers and belongings, but also allows users to quickly open or close the drawer with one hand, improving convenience and safety.

[0047] In the above-mentioned integrated system of refrigerated space in the central armrest area, the central armrest 1 is provided with an installation chamber 102, wherein the installation chamber 102 is located in front of the refrigerated chamber 10101, and a partition wall 103 is formed between the two; the partition wall 103 is a heat-conducting plate structure; the evaporator 4 is located in the installation chamber 102 and fixed on the heat-conducting plate structure.

[0048] The heat-conducting plate structure is made of thermally conductive materials, such as copper or aluminum. Thermally conductive silicone is coated between the front end of the evaporator 4 and the heat-conducting plate structure, while the remaining end faces are covered with an insulation layer, which is insulation cotton or other materials with thermal insulation properties. Utilizing the heat-conducting plate structure enables efficient heat transfer, improving the heat exchange efficiency of the evaporator 4. Simultaneously, the insulation layer prevents direct leakage of cold air, enhancing the energy efficiency ratio and refrigeration stability of the refrigeration system.

[0049] The aforementioned integrated system for the refrigerated space in the central armrest area also includes a branch air duct 11 located inside the central armrest 1. An air conditioning vent 104 is located at the rear end of the central armrest 1. The rear end of the branch air duct 11 connects to the air conditioning vent 104, and the front end connects to the vehicle's main air duct. Other branches of the main air duct connect to vents on the center console. The air conditioning vent 104 is located above the drawer entrance / exit 1012. This structure integrates the resources of the vehicle's original air conditioning system, introducing cool air to the vicinity of the refrigerated compartment 10101 through the branch air duct 11, optimizing the ambient temperature for rear passengers without affecting the normal operation of the refrigerated compartment 10101.

[0050] Furthermore, the central armrest 1 has two pipe installation gaps 105 inside, which are symmetrically arranged on the left and right sides of the refrigerator compartment 10101. The branch air ducts 11 split into two paths at their rear ends, passing through the pipe installation gaps 105 and connecting to the air conditioning outlets 104. This structure not only optimizes the space of the air duct layout, improves the uniformity of airflow and ventilation efficiency, but also enhances the symmetry and rationality of the overall system structure, which is conducive to improving assembly convenience and product reliability.

[0051] The method of using the integrated cold storage space system in the central armrest area of ​​this utility model is as follows:

[0052] When a front-row passenger needs items from storage drawer 2, they flip up the armrest panel 3 to open it, then retrieve the items from storage drawer 2 through the item access slot 1011. After retrieving the items, they close the armrest panel 3 back onto the item access slot 1011. When a rear-row passenger needs items from storage drawer 2, they pull back storage drawer 2 to open it, retrieve the items, and then push it back into the refrigerator compartment 10101.

[0053] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
