Description

Technical Field

[0001] This utility model belongs to the field of vehicle refrigerator technology, specifically relating to a portable vehicle refrigerator. Background Technology

[0002] Traditional car refrigerators are designed with a single storage compartment, relying on the haphazard stacking of items and beverages for basic storage. This design suffers from significant limitations in space adaptability. The continuous vibrations during vehicle movement easily cause bottles to tip over and items to collide, and current technologies, relying only on simple mesh frames or elastic bands for fixation, cannot meet the stability requirements under complex road conditions. Furthermore, the fixed compartment structure is difficult to accommodate items of different sizes, resulting in a space utilization rate of less than 40%. When large-capacity items are mixed with smaller, loose items, ineffective gaps can easily form, leading to uneven distribution of cooling airflow and localized temperature fluctuations, further increasing the risk of spoilage. Utility Model Content

[0003] The purpose of this utility model is to provide a portable vehicle-mounted refrigerator, comprising:

[0004] The refrigerator exterior has a transparent magnetic door on one side;

[0005] The refrigerator shell is equipped with a modified polystyrene plastic liner and an evaporator.

[0006] The inner liner sidewall is provided with two rows of opposing limiting protrusions, and a suspension rod and a partition are provided between the limiting protrusions. The surfaces of the suspension rod and the partition are both covered with a rubber layer.

[0007] Preferably, the suspension rod is provided with limit posts at both ends, the suspension rod has an arched boss in the middle, and a fixing post is provided directly below the limit posts;

[0008] The surface of the partition is provided with several breathable strips, and a fixed post is provided directly below each of the four corners of the partition.

[0009] Preferably, the upper surface of the limiting protrusion is provided with a plurality of equidistant grooves, the width of which is slightly larger than the bottom diameter of the fixing post.

[0010] Preferably, the refrigerator has a drawer-type water collection box at the bottom, which communicates with the interior of the inner liner through a water outlet at the bottom of the inner liner.

[0011] The beneficial effects of this utility model are:

[0012] By setting limiting protrusions, suspension rods, and partitions inside the refrigerator, the space utilization rate inside the refrigerator is maximized. The stability of the suspension rods and partitions is further improved by using fixing columns and grooves together, ensuring that the items are stable while ensuring the uniform distribution of cold air, thereby enhancing the refrigerator's cold preservation efficiency.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] like Figures 1 to 3 As shown, this embodiment provides a portable vehicle refrigerator, whose structure with power supply and cooling function is well known to those skilled in the art, and therefore will not be described in detail in this embodiment.

[0023] The refrigerator outer shell 1 has a transparent magnetic door on one side, which is made of highly transparent polycarbonate material and has good sealing performance to effectively prevent cold air leakage;

[0024] Inside the refrigerator outer shell 1, a modified polystyrene plastic liner 2 is installed. The modified polystyrene plastic liner 2 has excellent thermal insulation properties, effectively reducing cold loss, and also possesses good chemical corrosion resistance, preventing damage to the liner due to leakage of stored items. Inside the liner 2, an evaporator 3 is installed. The evaporator 3 is one of the core components of the refrigerator's refrigeration system, achieving cooling of the refrigerator's interior space through heat exchange with the refrigerant.

[0025] The inner liner 2 has two rows of opposing limiting protrusions 4 on its side wall. A suspension rod 5 and a partition 6 are arranged between the limiting protrusions 4. The suspension rod 5 is suitable for hanging items with ear loops on the rod, such as cup-shaped beverages that are easy to spill, such as coffee and milk tea. The suspension rod 5 has an arched protrusion 8 in the middle. The surfaces of the suspension rod 5 and the partition 6 are covered with a rubber layer to increase the friction between the items. Through the cooperation of the protrusion 8 and the surface rubber, multiple cups of beverages can be hung at one time, and they are spaced a certain distance apart, which can effectively prevent the beverages from colliding with each other.

[0026] The suspension rod 5 has limiting posts 7 at both ends, and a fixing post 9 is located directly below the limiting posts 7. The partition 6 has several ventilation strips 10 on its surface. The design of the ventilation strips 10 allows for more even circulation of cold air inside the refrigerator, improving cooling efficiency and preventing the refrigeration effect of items from being affected by excessively high or low local temperatures. A fixing post 9 is located directly below each of the four corners of the partition 6. The upper surface of the limiting protrusion 4 has several equidistant grooves 11, the width of which is slightly larger than the bottom diameter of the fixing post 9. The limiting posts 7 and the limiting protrusion 4 cooperate to achieve stable vertical positioning of the suspension rod 5, preventing it from bouncing up and down during vehicle movement. The fixing post 9 is used to fix the suspension rod 5 horizontally. The width of the grooves 11 is slightly larger than the bottom diameter of the fixing post 9, and the distance between each limiting protrusion 4 is sufficient to allow the fixing post 9 to be pulled out and then moved. This design ensures that the fixing post 9 can be smoothly inserted into the groove 11, preventing the suspension rod 5 and the partition 6 from sliding back and forth during vehicle operation.

[0027] The refrigerator outer shell 1 has a drawer-type water collection box 12 at its bottom, which communicates with the interior of the inner liner 2 through a drain hole at its bottom. The water collection box 12 is made of transparent plastic, making it easy for users to observe the water collection. When condensate or defrosting water from stored items accumulates inside the refrigerator to a certain level, it will flow into the water collection box 12 through the drain hole. Therefore, it is simple and convenient to just pull out the drawer-type water collection box 12 and empty the accumulated water periodically.

[0028] All the devices selected in this application (parts whose specific structures are not specified) are general standard parts or parts known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
