Description

A type of car refrigerator liner Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, and in particular to an inner liner for a vehicle-mounted refrigerator. Background Technology

[0002] As an important in-vehicle device for enhancing travel comfort and convenience, car refrigerators are facing increasing demands from consumers regarding their performance, quality, and user experience, driven by the booming automotive industry and rising living standards. Among these demands, the refrigerator's inner liner, a key component directly affecting storage performance, assembly quality, and overall user experience, has become a focus of research and innovation.

[0003] A typical car refrigerator consists of a shell and an inner liner. During manufacturing, foam material is injected into the area between the shell and the inner liner to form an insulation layer, ensuring the refrigerator's heat retention performance. The conventional inner liner structure usually employs a separate design between the inner liner and the frame, which are then glued together. However, this conventional separate inner liner structure has revealed numerous problems in practical applications, affecting the overall performance of the car refrigerator and the user experience.

[0004] 1. During the assembly process, the inner liner and the front frame are glued together, requiring a high degree of precision. Any operational errors or environmental interference can easily lead to assembly defects such as gaps and misalignment at the joint. These defects not only affect the overall appearance quality of the refrigerator's inner liner and reduce the product's sophistication, but more importantly, gaps and misalignment can compromise the refrigerator's internal sealing, thus affecting insulation performance, increasing energy consumption, and reducing cooling or heating efficiency.

[0005] 2. During the foaming process of the insulation material, if gaps or misalignments exist at the joint between the inner liner and the frame, the foam material can easily leak out through these gaps, resulting in leaked foam. Leaked foam not only contaminates the internal environment of the refrigerator, increasing the difficulty of subsequent cleaning, but also leads to uneven insulation layer thickness and localized areas of weak insulation performance. This further reduces the refrigerator's insulation effect, making it difficult to maintain a stable internal temperature, and may also affect the refrigerator's lifespan, increasing the user's maintenance and operating costs.

[0006] Given the shortcomings of the existing technology, it is of great significance to develop an inner liner structure that can effectively solve these problems and improve the overall performance of vehicle refrigerators. Summary of the Invention

[0007] This utility model provides a car refrigerator inner liner that can solve the problems of assembly defects and leakage of foam material in the prior art, thereby improving the cooling efficiency and heat preservation performance of the car refrigerator.

[0008] A vehicle refrigerator inner liner is disposed inside the refrigerator outer shell and includes an inner liner body and a face frame. The face frame is assembled and connected to the refrigerator outer shell and is disposed on the top of the inner liner body. The inner liner body and the face frame are integrally formed.

[0009] The inner liner body has a first placement cavity and a second placement cavity inside, and the first placement cavity and the second placement cavity are separated by a partition.

[0010] Furthermore, the partition protrudes upwards, and the depth of the first placement cavity is greater than the depth of the second placement cavity.

[0011] Furthermore, the partition platform is a boss extending upward from the adjacent sides of the first placement cavity and the second placement cavity, and the height of the partition platform is 10-15mm.

[0012] Furthermore, an mounting platform is provided on the side wall of the inner liner body near the second placement cavity. The mounting platform protrudes from the side wall of the inner liner body and is installed in conjunction with the external lampshade.

[0013] Furthermore, two fastening grooves are provided on the bottom side of the mounting platform, and a limiting groove is provided on the side of the mounting platform near the second placement cavity, with the external lampshade hidden in the limiting groove.

[0014] Furthermore, the fastening groove is an arc-shaped groove structure, and two fastening grooves are symmetrically arranged on both sides of the bottom of the mounting platform.

[0015] Furthermore, the depth of the limiting groove is adapted to the thickness of the outer lampshade, and the outer lampshade is flush with the side wall of the inner liner body.

[0016] Furthermore, the outer edge of the face frame is provided with a stepped assembly structure, and the face frame is fitted and fastened to the outer shell.

[0017] Furthermore, the inner liner body, the face frame, and the mounting platform are injection-molded integral polymer material components, and the polymer material is ABS engineering plastic or polypropylene.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] As shown in Figures 1 to 5, the embodiment of this utility model provides a vehicle refrigerator liner, which is disposed inside the outer shell of the refrigerator. It includes an inner liner body 1 and a face frame 2. The face frame 2 is assembled and connected to the outer shell of the refrigerator. The face frame 2 is disposed on the top of the inner liner body 1. At the same time, a mounting platform 3 is disposed on one side of the inner liner. The inner liner body 1, the face frame 2 and the mounting platform 3 are injection molded integral polymer material components. The polymer material is preferably ABS engineering plastic or polypropylene. Polypropylene boasts advantages such as lightweight, high temperature resistance, and food-grade properties, while ABS engineering plastics offer high strength, impact resistance, and chemical corrosion resistance, making them suitable for the vibrations and temperature variations in automotive environments. During use, the inner liner surface can be treated with a nano-coating to meet food contact standards. The one-piece molding process avoids the bonding defects of traditional split structures, improving structural stability while simplifying the production process and reducing assembly errors. This eliminates the problems of gaps, misalignments, and leakage of foam material at the joint between the inner liner body 1 and the face frame 2 during assembly and insulation material foaming. The wall thickness of the inner liner body 1 is controlled between 2.5-3.5mm, preferably 3mm. This thickness ensures the inner liner's strength, preventing deformation during transportation or use, while also reducing overall weight, meeting the lightweight requirements of automotive equipment.

[0031] Specifically, as shown in Figure 1, the outer edge of the face frame 2 is provided with a stepped assembly structure that matches the corresponding slot of the refrigerator's outer shell, so as to realize the fitting and fastening of the face frame 2 and the outer shell, replacing the traditional adhesive bonding, forming a mechanical lock, enhancing the connection stability, reducing glue volatilization pollution, and accurately positioning to ensure that the face frame 2 is aligned with the shell and avoid misalignment.

[0032] Specifically, as shown in Figures 2 to 4, the inner liner body 1 has a first placement cavity 11 and a second placement cavity 12 inside. The first placement cavity 11 and the second placement cavity 12 are separated by a partition platform 13. The partition platform 13 protrudes upward, and the depth of the first placement cavity 11 is greater than the depth of the second placement cavity 12, which facilitates the classification and placement of items of different heights, and improves the overall storage flexibility and space utilization.

[0033] The partition 13 is a rectangular boss with a rounded top and a height of 10-15mm, preferably 12mm. It extends upward from the adjacent side of the first placement cavity 11 and the second placement cavity 12. The partition 13 physically separates the first placement cavity 11 and the second placement cavity 12, preventing objects from being mixed and facilitating classified storage.

[0034] Specifically, as shown in Figure 3, the mounting platform 3 is set on the side wall of the inner liner body 1 near the second placement cavity 12. The mounting platform 3 protrudes from the side wall of the inner liner body 1 and is used to cooperate with the external lamp cover for installation.

[0035] Specifically, as shown in Figure 5, two snap-fit ​​grooves 31 are provided on the bottom side of the mounting platform 3. The snap-fit ​​grooves 31 are arc-shaped groove structures. The two snap-fit ​​grooves 31 are symmetrically arranged on both sides of the bottom of the mounting platform 3 for engaging the protruding buckles of the lamp panel bracket. The snap-fit ​​grooves and the lamp panel bracket buckles form a mechanical fixation, simplifying the assembly process and enabling quick installation of the lamp cover and lamp panel. A limiting groove 32 is provided on the side of the mounting platform 3 near the second placement cavity 12. The depth of the limiting groove 32 is adapted to the thickness of the external lamp cover, making it easy for the external lamp cover to be hidden in the limiting groove 32. In addition, the limiting groove 32 ensures that the external lamp cover is flush with the side wall of the inner liner body 1 after being embedded, avoiding damage or falling off the lamp cover when taking out and storing items, while improving the flatness of the appearance.
