[0045] The main box body 1 and the auxiliary box body 2 are two separable independent components, so that workers can have more operating space when installing the refrigeration tank 11 and the refrigeration mechanism, which relatively reduces the difficulty of assembly and is conducive to improving production efficiency.

[0046] A bottom plate 41 is provided in the electrical cavity. The side of the bottom plate 41 close to the main box body 1 is connected and fixed to the main box body 1. The front and rear ends of the bottom plate 41 away from the main box body 1 are respectively connected to corresponding vertical rods 42. The vertical rods 42 are arranged vertically. The bottom plate 41 is detachable from the main box body 1 and the vertical rods 42 respectively. The sub-box body 2 is installed and fixed to the bottom plate 41 and / or the vertical rods 42. The bottom plate 41 and the vertical rods 42 are arranged between the main box body 1 and the sub-box body 2 to improve the overall structural strength of the electrical cavity. Moreover, the bottom plate 41 can be connected and cooperated with the vertical rods 42 of different heights to adapt to the needs of electrical cavity of different heights, thereby improving the versatility of the components.

[0047] Preferably, a control panel is provided on the outside of the main box body 1 or the auxiliary box body 2, and the control panel is electrically connected to the ice maker 3 and the refrigeration mechanism.

[0048] Furthermore, the assembly mechanism includes buckle holes 12 and undercut portions 21 respectively arranged on the main box body 1 and the auxiliary box body 2. The undercut portions 21 and the buckle holes 12 are buckled with each other so that the main box body 1 and the auxiliary box body 2 can be connected and fixed in the horizontal direction. The undercut portions 21 and the buckle holes 12 can be misaligned in the vertical direction so that the main box body 1 and the auxiliary box body 2 can be detached from each other, which facilitates quick disassembly and assembly between the main box body 1 and the auxiliary box body 2, and is convenient for workers to produce, install, and overhaul and maintain.

[0049] Furthermore, a pre-entry portion 121 is provided at the lower side of the button hole 12, the width of the pre-entry portion 121 is greater than the width of the upper side of the button hole 12, and a guide slope 122 is provided between the pre-entry portion 121 and the upper side of the button hole 12, and the guide slope 122 is inclined from bottom to top toward the inner side, so that the undercut portion 21 can more easily enter the pre-entry portion 121 and finally connect with the upper side of the button hole 12, which can simplify the installation difficulty of the undercut portion 21 and the button hole 12 and ensure that the two have good connection stability. A connecting plane 22 is provided on one side of the auxiliary box 2 facing the main box 1 , and the undercut portion 21 is provided on the connecting plane 22 . The connecting plane 22 abuts against the side wall of the main box 1 , further improving the stability of the connection between the auxiliary box 2 and the main box 1 .

[0050] The main box body 1 is provided with a positioning recess 13 corresponding to the connecting plane 22, the connecting plane 22 is abutted against the positioning recess 13, and the buckle hole 12 is provided on the positioning recess 13, so that the installation accuracy between the main box body 1 and the auxiliary box body 2 is higher and the connection stability is better.

[0051] Furthermore, a cross bar 43 is connected between the vertical bars 42. The cross bar 43 is arranged in the transverse direction. The front and rear ends of the cross bar 43 are respectively installed and fixed to the vertical bars 42, so as to improve the structural stability between the vertical bars 42 and make the vertical bars 42 less likely to deviate.

[0052] The horizontal bar 43 is provided with a positioning pin 431, and the vertical bar 42 is provided with a positioning hole 421 corresponding to the positioning pin 431. The positioning pin 431 and the positioning hole 421 are plugged into and matched to connect and position the horizontal bar 43 and the vertical bar 42 to each other, thereby improving the installation accuracy of the horizontal bar 43 and the vertical bar 42 and further improving the connection strength between the two.

[0053] A bending portion 422 is provided on the vertical rod 42, and the bending portion 422 is in an inclined shape. The bending portion 422 is inclined from top to bottom toward the main box body 1, and the upper side of the cross bar 43 abuts against the lower side of the bending portion 422. The bending portion 422 can improve the structural strength of the vertical rod 42 and at the same time have a certain positioning effect on the cross bar 43.

[0054] A foot 423 is provided at the bottom of the vertical rod 42 in the horizontal direction, and a limiting groove 411 corresponding to the foot 423 is provided on the bottom plate 41. The foot 423 is engaged with the limiting groove 411 and is locked and fixed by a screw device, thereby improving the installation accuracy of the vertical rod 42 and the bottom plate 41 and making the connection stability between the two better.

[0055] The side of the vertical rod 42 is provided with a flange 424, which extends toward the main box body 1. The vertical rod 42 and the flange 424 form a frame structure with a U-shaped cross-section. The structural strength of the vertical rod 42 can be further improved without significantly increasing the weight and material cost of the vertical rod 42, and at the same time, the vertical rod 42 has a thicker visual thickness.

[0056] Furthermore, the ice maker 3 includes a lifting bucket 31, which has a storage chamber for storing liquid. An evaporating tube 32 is provided on the outer side of the lifting bucket 31 for cooling the storage chamber. The inner side of the evaporating tube 32 is adjacent to the outer side of the lifting bucket 31. A sealing ring 4 is provided between the lifting bucket 31 and the evaporating tube 32. The sealing ring 4 is circumferentially arranged between the lifting bucket 31 and the evaporating tube 32. The sealing ring 4 is tightly matched with the lifting bucket 31 and the evaporating tube 32 respectively. The sealing ring 4 can reduce the chance of liquid entering the evaporating tube 32, avoid the situation where the lifting bucket 31 and the evaporating tube 32 are frozen and stuck due to the low temperature agglomeration of liquid in the evaporating tube 32, and ensure that the lifting bucket 31 can be smoothly extracted.

[0057] Furthermore, the upper sides of the lifting bucket 31 and the evaporating tube 32 are both open, and the sealing ring 4 is provided with an embedding groove 41 corresponding to the peripheral position of the opening of the lifting bucket 31. The peripheral edge of the opening of the lifting bucket 31 is embedded in the embedding groove 41 and fits tightly with each other. The sealing ring 4 is at least partially tightly fitted with the evaporating tube 32. The embedding groove 41 can increase the connection strength between the sealing ring 4 and the lifting bucket 31. The sealing ring 4 is pressed against the evaporating tube 32 by the gravity of the lifting bucket 31, which can avoid the sealing ring 4 from shifting due to friction between the evaporating tube 32 when the user takes out the lifting bucket 31.

[0058] The opening periphery of the bucket 31 is tilted upward from the inside to the outside, and the shape of the engaging groove 41 is equivalent to the shape of the opening periphery of the bucket 31. The sealing ring 4 wraps the opening periphery of the bucket 31 from top to bottom through the engaging groove 41, further reducing the chance of the sealing ring 4 accidentally falling off from the opening periphery of the bucket 31. Furthermore, the bucket 31 is connected to a hanging handle 311, which is movably connected to the bucket 31. The hanging handle 311 is vertically placed above the opening of the bucket 31 to form an open state, or the hanging handle 311 is horizontally placed above the opening of the bucket 31 to form a storage state, so that the user can easily extract or place the bucket 31, and after the bucket 31 is placed, the extra space occupied by the hanging handle 31 can be minimized.

[0059] The left and right sides of the opening of the bucket 31 are respectively provided with connecting ears 312 corresponding to the hanging handle 311, and the head and tail ends of the hanging handle 311 are movably connected to the connecting ears 312, thereby improving the stability of the user when extracting or placing the bucket 31.

[0060] The sealing ring 4 is provided with a plug-in groove 42 corresponding to the connecting ear 312. The connecting ear 312 passes through the sealing ring 4 from bottom to top through the plug-in groove 42. The head and tail ends of the hanging handle 311 are movably connected to the position above the sealing ring 4 corresponding to the connecting ear 312, which can reduce the flow of liquid from the position of the connecting ear 312 into the evaporating cylinder 32. At the same time, the hanging handle 311 can have a certain limiting effect on the sealing ring 4, further reducing the chance of the sealing ring 4 accidentally falling off from the bucket 31.

[0061] Furthermore, an agitator 5 is provided in the accommodating chamber, and the agitator 5 has a rotating shaft 53, and the rotating shaft 53 is connected to a driving device 6. The agitator 5 rotates around the rotating shaft 53 through the driving device 6. A scraper portion 54 is provided on the radial outer side of the agitator 5. The scraper portion 54 is vertically arranged, so that ice crystals at more different positions on the inner wall of the accommodating chamber can be scraped away by the scraper portion 54.

[0062] The scraper portion 54 is provided with a scraper edge 541 at the front end corresponding to the rotation direction of the stirrer 5. The scraper edge 541 is adjacent to the inner wall of the accommodating cavity. The scraper edge 541 will not directly come into frictional contact with the accommodating cavity, thereby reducing the wear between the scraper edge 541 and the accommodating cavity.

[0063] The agitator 5 can make smoothies or ice cream, enriching the functions of the vehicle refrigerator. At the same time, the agitator 5 can also prevent excessive ice crystals from accumulating on the inner wall of the accommodating cavity, improve the heat transfer efficiency between the liquid inside the accommodating cavity and the outside, so as to make the overall ice-making effect of the product better.

[0064] Furthermore, a stirring rib extending in the radial direction is provided on the outer side of the rotating shaft 53, and the end of the stirring rib facing away from the stirring shaft is connected to the scraper portion 54. The rotating shaft 53, the stirring rib and the scraper portion 54 are integrally formed with metal or plastic material. The stirring rib can stir the liquid in the middle position of the accommodating cavity to make the refrigeration effect more uniform, and at the same time can further improve the overall structural strength of the agitator 5.

[0065] The agitator 5 has two scraping parts 54, which are respectively arranged on the left and right sides of the agitator 5. The stirring rib part includes a first stirring rib 51 and a second stirring rib 52, which are respectively connected to the scraping parts 54 on the left and right sides. The first stirring rib 51 is inclined downward along the rotation direction of the agitator 5. The first stirring rib 51 is provided with a bending structure at the middle position of the radial direction. The inclination of the first stirring rib 51 corresponding to the bending structure to the rotating shaft 53 is greater than the inclination of the first stirring rib 51 corresponding to the bending structure to the scraping part 54. The second stirring rib 52 is arranged in the horizontal direction. The first stirring rib 51 and the second stirring rib 52 cooperate to stir and fry the liquid in the accommodating cavity, so that the refrigeration effect is more uniform.

[0066] An axis positioning portion 531 is provided at the other end of the rotating shaft 53 corresponding to the driving device 6, and a cavity positioning portion 55 corresponding to the axis positioning portion 531 is provided on the accommodating cavity. The axis positioning portion 531 and the cavity positioning portion 55 are respectively in corresponding arc shapes, and the axis positioning portion 531 and the cavity positioning portion 55 slide in cooperation with each other, thereby improving the stability of the rotation process of the agitator 5.

[0067] A plurality of ice-making trays 6 are arranged in the accommodating chamber, and a plurality of ice-condensing cavities 61 for storing liquid are arranged in a grid shape in the ice-making trays 6. The ice-making trays 6 are stacked in sequence vertically to form an ice tray group, and a limiting mechanism is formed between the vertically adjacent ice-making trays 6. The vertically adjacent ice-making trays 6 are vertically detachable and separable from each other and fixed in position horizontally by the limiting mechanism. The ice tray group formed by stacking the ice-making trays 6 can better utilize the spatial position inside the accommodating chamber, so that relatively more ice-condensing cavities 61 can be formed in the accommodating chamber, thereby increasing the number of ice cubes produced each time the refrigeration is performed. At the same time, the combination of the ice-making trays 6 is relatively flexible and can adapt to more usage requirements. Moreover, the limiting mechanism can improve the stability of the ice tray group structure, and the ice tray group is not easy to disintegrate during the ice-making process.

[0068] Furthermore, the limiting mechanism includes an upper rib 62 and a lower rib 63 respectively arranged on the upper and lower sides of the ice tray 6. The lower rib 63 of the ice tray 6 on the upper side abuts against the upper rib 62 of the ice tray 6 on the lower side in the horizontal direction, and the upper rib 62 of the ice tray 6 on the lower side abuts against the lower side of the ice tray 6 on the upper side in the vertical direction. The installation structure between the upper and lower adjacent ice trays 6 is simple and has a good positioning effect.

[0069] Furthermore, the accommodating cavity is cylindrical in shape, and an arc surface 64 is provided on the side of the ice tray 6 away from the center of the accommodating cavity. The arc surface 64 is concentrically arranged with the accommodating cavity, which simplifies the action of aligning the ice tray 6 with the accommodating cavity and makes it easier for the user to place the ice tray 6 into the accommodating cavity.

[0070] A plurality of ice tray groups are arranged in the accommodating cavity, and gaps are formed between the ice tray groups for the agitator 5 to pass through. The idle agitator 5 and ice tray groups can be placed in the accommodating cavity at the same time, so that the ice tray groups and the agitator 5 can be stored conveniently.
