[0023] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0024] As shown in the figure, a novel lower shell structure of an inner tank of a vehicle refrigerator includes: an inner tank shell 1; the inner tank shell 1 includes a placement component 2 and a plug-in component 3 arranged on the top of the placement component 2;
[0025] It should be noted that the placement component 2 and the plug-in component 3 are vertically arranged, and the inner shell 1 is first prepared by the vacuum forming process to form a cavity with an open top, thereby forming the placement component 2, and at this time there is an extra part on the top of the placement component 2, and then the parts at multiple locations on the top of the placement component 2 are bent twice by a bending process to form the plug-in component 3, and the bending part of the plug-in component 3 is used to fit the car part, and the plug-in component 3 is used to fix the structure of the device.
[0026] The placement component 2 includes a placement shell, and a placement cavity 20 is formed inside the placement shell. The placement cavity 20 is used to store items that need to be refrigerated, such as food and medicine; the top of the placement cavity 20 is set in an open shape;
[0027] In a preferred embodiment of the utility model, the placement shell is arranged in a rectangular shape, and the thickness of the placement shell is 0.6 cm.
[0028] It should be noted that the placement shell is a shell with an opening on the top formed by vacuum forming, and a rectangular placement cavity 20 is formed inside the placement shell. There are multiple parts at the top opening of the placement shell. The thickness of the placement shell is 0.6 cm, and the placement shell is made of ABS plastic material made of a ternary copolymer of three monomers of acrylonitrile A, butadiene B, and styrene S.
[0029] The plug-in component 3 includes a bending piece, a bending groove 32 arranged on the bending piece, and a plug-in notch 33 arranged on the bending piece; the bending piece is vertically arranged on the top of the shell, and the plug-in notch 33 is used for plugging with the vehicle body.
[0030] It should be noted that the plug-in component 3 is formed by bending multiple parts of the top opening of the placement shell through a bending process, so as to form a bent part. The bending groove 32 and the plug-in notch 33 are both arranged on the bent part, and are both formed in the process of blow molding the placement shell.
[0031] In a preferred embodiment of the present invention, the bending piece includes a first bending edge 30 and a second bending edge 31 arranged perpendicular to the first bending edge; the bending piece is obtained by placing the top of the shell and bending it.
[0032] In a preferred embodiment of the present invention, the first bending edge 30 is vertically arranged with respect to the placement shell, and the first bending edge 30 is vertically arranged with respect to the second bending edge 31 .
[0033] It should be noted that the bending part includes a first bending edge 30 and a second bending edge 31. The first bending edge 30 and the second bending edge 31 are formed by two bending processes. After the two bending processes, a bending part is formed on the top of the placement shell, and the inner shell 1 is divided into a placement part 2 and a plug-in part 3. The first bending edge 30, the second bending edge 31 and the placement shell are arranged in sequence from the top of the shell to the bottom, and the first bending edge 30, the second bending edge 31 and the placement shell are all vertically arranged.
[0034] In a preferred embodiment of the present invention, a plurality of bending grooves 32 are provided, and the bending grooves 32 are provided on the second bending edge 31 .
[0035] In a preferred embodiment of the present invention, the bending groove 32 is overall in a smooth concave shape.
[0036] It should be noted that the bending groove 32 is arranged on the second bending edge 31, and there are several of them. The overall cross-section of the second bending edge 31 is a square ring-shaped arrangement connected end to end, and the bending groove 32 is opened at the corner of the square. The bending groove 32 is overall smoothly concave, that is, the bending groove 32 is smooth and groove-shaped. During the blow molding process, a smooth groove is formed at the corner where the top opening of the shell is placed. Therefore, during the bending process, since the corner is groove-shaped, the stress of the adjacent edges and the pulling force of the adjacent edges at the corners of the four sides of the second bending edge 31 are reduced, thereby greatly reducing the occurrence of rupture at the corners due to the pulling force.
[0037] In a preferred embodiment of the present invention, a plurality of insertion notches 33 are provided and are symmetrically opened on the bending part. The insertion notches 33 are used to fix the inner shell 1.
[0038] In a preferred embodiment of the present invention, the insertion notch 33 is only disposed on one side of the second bending edge 31 , and the insertion notches 33 are symmetrically disposed on the second bending edge 31 .
[0039] It should be noted that the plug-in notch 33 includes a main notch and two sub-notches, and the two negative notches are symmetrically arranged on both sides of the main notch. The second bending edge 31 has a square ring-shaped cross-section as a whole. It can be seen that the second bending edge 31 has four sides, and the plug-in notch 33 is opened on one of the sides.
[0040] In a preferred embodiment of the utility model, the inner shell is provided with an upper base 10 and a lower base 11 respectively, the upper base 10 is clamped with the bending part, and the lower base 11 is transitionally matched with the placement shell.
[0041] It should be noted that the lower base 11 is a square groove, and its groove shape is the same as the bottom of the placement shell. During the installation process, the inner shell is fixed by the upper base 1010 and the lower base 11. The lower base 11 is first fixed to the refrigerator or the car body by bolts, and then the inner shell is lowered so that the bottom of the inner shell is located in the groove of the lower base 11, and the lower base 11 is transitionally matched with the bottom of the placement shell, so that when the bottom of the inner shell is completely located inside the groove of the lower base 11, the lower base 11 forms a surrounding type for the bottom of the inner shell. In the fixed state, the lower base 11 completely fixes the bottom of the inner tank shell there, and the upper base 1010 is fixedly connected to the outer refrigerator, a clip is provided at the bottom of the upper base 1010, and the position of the clip corresponds to the plug-in notch 33, the clip is L-shaped, and a fixing plate is also provided around the upper base 1010, and the fixing plate is provided with a notch at the bottom. During the fixing process relative to the inner tank shell, as the upper base 1010 is lowered, the clip enters the plug-in notch and forms a snap connection with the plug-in notch, and the notch at the bottom of the fixing plate is stuck on the second bent edge.
[0042] When the utility model is used, the first bending edge 30 is supported on the inner shell of the car and is fixed by the second bending edge 31. The shape surrounded by the second bending edge 31 is the shape of the inner side of the car refrigerator, and the second bending edge 31 is interference fit with the car refrigerator shell. When the lower shell of the inner liner is placed inside the car refrigerator, a semi-fixed state is formed, and finally it is completely fixed to the inner liner through the plug-in notch 33.
[0043] The above is based on the ideal embodiment of the utility model. Through the above description, relevant personnel can make various changes and modifications without deviating from the technical concept of the utility model. The technical scope of this utility model is not limited to the content in the specification, and the technical scope must be determined according to the scope of the claims.
