[0003] Existing vehicle refrigerators all have a refrigerator frame to assemble components such as the inner or outer casing. To reduce production costs, the refrigerator frame is usually injection molded from a combination of PP and fiberglass. However, PP and fiberglass lack sufficient rigidity during molding, and the top and front of the refrigerator's outer frame are open, making them prone to warping and deformation after demolding. This not only results in a low yield rate but also affects subsequent assembly of components such as the inner or outer casing. Therefore, further improvements are necessary. Utility Model Content

[0027] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example

[0029] See Figures 1-8 The frame forming auxiliary device of this vehicle refrigerator includes a support rod 1 and a cabinet frame 2 with an opening 2.1 on at least one side. The bottom ends of the support rod 1 are respectively provided with clamping grooves 1.1. The support rod 1 is positioned and clamped on the upper edge of the opposite side walls of the opening 2.1 through the clamping grooves 1.1 at both ends, so as to realize the support forming of the opening 2.1 of the cabinet frame 2.

[0030] In this embodiment, the clamping grooves 1.1 at both ends of the support rod 1 provide rigid support for the open opening of the cabinet frame 2, which effectively prevents the cabinet frame 2 from warping and deforming after injection molding and demolding, thereby improving the yield of the cabinet frame 2. It also facilitates the subsequent assembly of components such as the inner or outer cabinet. In addition, the frame forming auxiliary device can adopt a modular design, which can be flexibly combined according to the cabinet frame 2 of different sizes. Moreover, it is easy to assemble and disassemble, and can be reused, which significantly improves the production efficiency and yield of the vehicle refrigerator and reduces the manufacturing cost.

[0031] The box frame 2 is a roughly rectangular frame structure, with an opening 2.1 on at least one of its top and front sides for assembling components such as the inner box or door. The support rod 1 is a long strip component with clamping grooves 1.1 at both ends of its bottom.

[0032] After the box frame 2 is demolded, the clamping grooves 1.1 at both ends of the support rod 1 are immediately engaged with the top of the side walls on both sides of the open opening 2.1. Through the rigid support of the support rod 1, the box frame 2 resists the warping deformation caused by the release of internal stress during the cooling process, thereby maintaining the size and shape stability of the open opening 2.1.

[0033] The clamping groove 1.1 is fixedly mounted on the support rod 1, or the clamping groove 1.1 is adjustablely mounted on the support rod 1 to accommodate box frames 2 of different sizes.

[0034] There may be one clamping slot 1.1 or multiple clamping slots 1.1 arranged at intervals.

[0035] Specifically, in this embodiment, the clamping groove 1.1 is integrally formed on the support rod 1, and two clamping grooves 1.1 are provided at one end, with the two clamping grooves 1.1 arranged at intervals.

[0036] The clamping groove 1.1 is formed by a first protrusion 1.2 and a second protrusion 1.3 that are spaced apart from each other. The first protrusion 1.2 and the second protrusion 1.3 are integrally injection molded with the support rod 1 body, resulting in a robust structure. The side wall edge of the box frame 2 is accommodated in the clamping groove 1.1 between the first protrusion 1.2 and the second protrusion 1.3. At the same time, the clamping action of the two clamping grooves 1.1 provides stable dual-point positioning of the opening 2.1 of the box frame 2, effectively limiting the warping deformation of the side wall of the box frame 2 in both the horizontal and vertical directions.

[0037] The first protrusion 1.2 and / or the second protrusion 1.3 are provided with clamping guide surfaces 1.4 in the direction of the side wall of the open opening 2.1, and clamping reinforcing ribs 1.5 are provided on the first protrusion 1.2 and / or the second protrusion 1.3.

[0038] In this embodiment, both the first protrusion 1.2 and the second protrusion 1.3 are provided with a clamping guide surface 1.4 and a clamping reinforcing rib 1.5. The clamping guide surface 1.4 can guide the edge of the side wall of the housing frame 2 to slide smoothly into the clamping groove 1.1 during installation, improving assembly efficiency. The clamping reinforcing rib 1.5 can enhance the structural strength of the clamping groove 1.1 and prevent it from deforming after long-term use.

[0039] A support rod 1 is provided, and the opening 2.1 of the box frame 2 can be supported and formed by the support rod 1.

[0040] In addition, multiple struts 1 are provided, which are spaced apart and parallel to each other. Specifically, three struts 1 are provided, which are spaced apart and parallel to each other. The three struts 1 are used to support the left and right areas of the open opening 2.1 respectively to provide uniform support force.

[0041] To ensure that the relative positions of the three struts 1 are fixed and to form a stable overall support structure, a connecting rod 3 is provided between the three struts 1.

[0042] The connecting rod 3 can be integrally formed with the support rod 1. Otherwise, the support rod 1 and the connecting rod 3 are independent components, and the two are fixed together by snaps, fasteners, magnetic attraction, or adhesive.

[0043] Among them, the support rod 1 and the connecting rod 3 are perpendicular or inclined to each other.

[0044] Specifically, the support rod 1 is provided with a support hole 1.6, and the connecting rod 3 is provided with a connecting hole 3.1. The connecting hole 3.1 and the support hole 1.6 correspond to each other and are fixedly engaged by fasteners. During assembly, bolts or screws are used to pass through the connecting hole 3.1 and the support hole 1.6 in sequence and tighten them to firmly fix the connecting rod 3 between the two support rods 1.

[0045] There is one connecting rod 3, meaning that the three support rods 1 can be fixed together by one connecting rod 3. In addition, there are multiple connecting rods 3, which are arranged at intervals and are parallel or staggered to each other. That is, the three support rods 1 can be fixed together by multiple connecting rods 3 that are parallel or staggered to each other.

[0046] In this embodiment, two connecting rods 3 are provided. The two connecting rods 3 are parallel to each other and fixed to the three support rods 1 at intervals, thereby forming a modular frame forming auxiliary device between the support rods 1 and the connecting rods 3. Moreover, the support rods 1 and the connecting rods 3 are perpendicular to each other, thereby improving the shaping effect.

[0047] To achieve rapid pre-positioning and prevent displacement of the connecting rod 3 during tightening, a first positioning part 1.7 and a second positioning part 1.8 are also provided on the support rod 1. The first positioning part 1.7 and the second positioning part 1.8 are spaced apart and located on both sides of the support hole 1.6, thus forming a pre-positioning groove 1.9. When installing the connecting rod 3, the end of the connecting rod 3 can be inserted into the pre-positioning groove 1.9 first. At this time, the connecting hole 3.1 and the support hole 1.6 are automatically and approximately aligned, and then the fastener can be easily screwed in, greatly simplifying the assembly process.
