[0044] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0045] See Figures 1-23 This vehicle-mounted refrigerator with ice-making function includes a main body 1, inside which is a refrigerated inner liner 11 for storing food and beverages. A secondary body 2 is connected to the outside of the main body 1. The main body 1 and the secondary body 2 are connected and fixed by an assembly mechanism, forming an electrical cavity between the main body 1 and the secondary body 2. The electrical cavity contains a refrigeration mechanism and an ice maker 3. The ice maker 3 and the refrigeration mechanism are arranged sequentially from top to bottom. The ice maker 3 and the refrigeration mechanism are connected by a pipe. The ice maker 3 can better utilize the space above the refrigeration mechanism, so that the vehicle-mounted refrigerator can simultaneously make ice and cool the storage cavity. At the same time, the overall layout is relatively reasonable, which can save more space and make it convenient for users.

[0046] The main body 1 and the auxiliary body 2 are two separate and independent components, which gives workers more operating space when installing the refrigerator inner liner 11 and the refrigeration mechanism, thus reducing the assembly difficulty and improving production efficiency.

[0047] The electrical cavity is equipped with a base plate 41. The side of the base plate 41 closest to the main housing 1 is connected and fixed to the main housing 1. The front and rear ends of the side of the base plate 41 away from the main housing 1 are respectively connected to corresponding vertical rods 42. The vertical rods 42 are set vertically. The base plate 41 is detachable from the main housing 1 and the vertical rods 42. The auxiliary housing 2 is installed and fixed to the base plate 41 and / or the vertical rods 42. The base plate 41 and the vertical rods 42 are set between the main housing 1 and the auxiliary housing 2, which can improve the overall structural strength of the electrical cavity. Moreover, the base plate 41 can be connected and cooperate with the vertical rods 42 of different heights to adapt to the needs of electrical cavities of different heights, thereby improving the versatility of the components.

[0048] Preferably, a control panel is provided on the outside of the main housing 1 or the auxiliary housing 2, and the control panel is electrically connected to the ice maker 3 and the refrigeration mechanism.

[0049] Furthermore, the assembly mechanism includes buckle holes 12 and undercut parts 21 respectively provided on the main housing 1 and the auxiliary housing 2. The undercut parts 21 and buckle holes 12 can be fastened together to connect and fix the main housing 1 and the auxiliary housing 2 in the horizontal direction. The undercut parts 21 and buckle holes 12 can be misaligned in the vertical direction to make the main housing 1 and the auxiliary housing 2 detachable and separable from each other, which facilitates quick assembly and disassembly between the main housing 1 and the auxiliary housing 2, and facilitates production, installation and maintenance by workers.

[0050] Furthermore, a pre-insertion portion 121 is provided on the lower side of the buckle hole 12. The width of the pre-insertion portion 121 is greater than the width of the upper side of the buckle hole 12. A guide slope 122 is provided between the pre-insertion portion 121 and the upper side of the buckle hole 12. The guide slope 122 is inclined from bottom to top inward, so that the buckle portion 21 can enter the pre-insertion portion 121 more easily and finally connect and cooperate with the upper side of the buckle hole 12. This simplifies the installation difficulty of the buckle portion 21 and the buckle hole 12 and ensures that the two have good connection stability.

[0051] The auxiliary housing 2 has a connecting plane 22 on the side facing the main housing 1. The inverted part 21 is set on the connecting plane 22, and the side wall of the main housing 1 of the connecting plane 22 abuts against it, further improving the stability of the connection between the auxiliary housing 2 and the main housing 1.

[0052] The main housing 1 is provided with a positioning recess 13 corresponding to the connecting plane 22. The connecting plane 22 and the positioning recess 13 abut against each other. The buckle hole 12 is provided on the positioning recess 13, which makes the installation accuracy between the main housing 1 and the auxiliary housing 2 higher and the connection stability better.

[0053] Furthermore, a horizontal bar 43 is connected between the vertical bars 42. The horizontal bar 43 is arranged in the horizontal direction, and its front and rear ends are respectively installed and fixed to the vertical bars 42 to improve the structural stability between the vertical bars 42 and make the vertical bars 42 less prone to displacement.

[0054] 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 inserted and matched to connect and position the horizontal bar 43 and the vertical bar 42, thereby improving the installation accuracy of the horizontal bar 43 and the vertical bar 42 and further improving the connection strength between the two.

[0055] The vertical rod 42 is provided with a bending part 422, which is in the shape of an inclined plane. The bending part 422 is inclined from top to bottom towards the main box 1. The upper side of the horizontal rod 43 abuts against the lower side of the bending part 422. The bending part 422 can improve the structural strength of the vertical rod 42 and at the same time play a certain positioning role for the horizontal rod 43.

[0056] The bottom of the vertical rod 42 is provided with a foot 423 arranged in the horizontal direction, and the base plate 41 is provided with a limiting groove 411 corresponding to the foot 423. The foot 423 and the limiting groove 411 are engaged and locked by a screw device, which improves the installation accuracy of the vertical rod 42 and the base plate 41, and at the same time makes the connection stability of the two better.

[0057] The side of the vertical rod 42 is provided with a flange 424, which extends toward the main box 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, while also giving the vertical rod 42 a thicker visual thickness.

[0058] Furthermore, the ice maker 3 includes a bucket 31, which has a cavity for storing liquid. An evaporator 32 is provided on the outside of the bucket 31 to cool the cavity. The inside of the evaporator 32 is adjacent to the outside of the bucket 31. A sealing ring 4 is provided between the bucket 31 and the evaporator 32. The sealing ring 4 is circumferentially disposed between the bucket 31 and the evaporator 32. The sealing ring 4 is tightly fitted with the bucket 31 and the evaporator 32 respectively. The sealing ring 4 can reduce the chance of liquid entering the evaporator 32 and prevent the liquid from freezing and sticking to the bucket 31 due to low temperature in the evaporator 32, thus ensuring that the bucket 31 can be easily lifted.

[0059] Furthermore, both the upper sides of the bucket 31 and the evaporator 32 are open. The sealing ring 4 is provided with an interlocking groove 44 corresponding to the periphery of the opening of the bucket 31. The periphery of the opening of the bucket 31 is embedded in the interlocking groove 44 and fits tightly with each other. The sealing ring 4 is at least partially fitted with the evaporator 32. The interlocking groove 44 can improve the connection strength between the sealing ring 4 and the bucket 31. The sealing ring 4 is pressed onto the evaporator 32 by the weight of the bucket 31, which can prevent the sealing ring 4 from shifting due to friction between the sealing ring 4 and the evaporator 32 during the process of the user taking out the bucket 31.

[0060] The opening periphery of the bucket 31 is inclined upward from the inside out, and the shape of the fitting groove 44 is similar to the shape of the opening periphery of the bucket 31. The sealing ring 4 wraps around the opening periphery of the bucket 31 from top to bottom through the fitting groove 44, further reducing the chance of the sealing ring 4 accidentally falling off from the opening periphery of the bucket 31.

[0061] Furthermore, the bucket 31 is connected to a handle 311, which is movably connected to the bucket 31. The handle 311 is vertically positioned above the opening of the bucket 31 to form an open state, or the handle 311 is horizontally positioned above the opening of the bucket 31 to form a retracted state, making it convenient for users to pick up or place the bucket 31. Moreover, after placing the bucket 31, the additional space occupied by the handle 311 can be minimized.

[0062] The bucket 31 has connecting lugs 312 on the left and right sides of the opening, which correspond to the handle 311. The two ends of the handle 311 are movably connected to the connecting lugs 312, which improves the stability of the user when picking up or placing the bucket 31.

[0063] The sealing ring 4 is provided with a insertion groove 45 corresponding to the connecting lug 312. The connecting lug 312 passes through the sealing ring 4 from bottom to top via the insertion groove 45. The two ends of the lifting handle 311 are respectively movably connected to the position above the sealing ring 4 corresponding to the connecting lug 312. This can reduce the flow of liquid from the position of the connecting lug 312 into the evaporator 32. At the same time, the lifting handle 311 can play a certain limiting role for the sealing ring 4, further reducing the chance of the sealing ring 4 accidentally falling off the lifting bucket 31.

[0064] Furthermore, a stirrer 5 is provided inside the accommodating cavity. The stirrer 5 has a rotating shaft 53, which is connected to a drive device 7. The stirrer 5 rotates around the rotating shaft 53 via the drive device 7. A scraping part 54 is provided on the radially outer side of the stirrer 5. The scraping part 54 is arranged vertically, which can scrape away more ice crystals at different positions on the inner wall of the accommodating cavity.

[0065] The scraping section 54 is provided with a scraping edge 541 at the front end corresponding to the rotation direction of the agitator 5. The scraping edge 541 is adjacent to and fits with the inner side wall of the accommodating cavity. The scraping edge 541 will not directly rub against the accommodating cavity, thereby reducing the wear between the scraping edge 541 and the accommodating cavity.

[0066] The blender 5 can make smoothies or ice cream, enriching the functionality of the car refrigerator. At the same time, the blender 5 can also prevent excessive ice crystals from accumulating on the inner wall of the container, improve the heat transfer efficiency between the liquid inside the container and the outside, and thus make the overall ice-making effect of the product better.

[0067] Furthermore, the outer side of the rotating shaft 53 is provided with a stirring rib extending radially. The end of the stirring rib facing away from the stirring shaft is connected to the scraping part 54. The rotating shaft 53, the stirring rib and the scraping part 54 are integrally formed by metal or plastic materials. The stirring rib can stir the liquid in the middle position of the accommodating cavity, making the cooling effect more uniform, and at the same time, it can further improve the overall structural strength of the stirrer 5.

[0068] The agitator 5 has two scraping sections 54, which are respectively located on the left and right sides of the agitator 5. The agitating ribs include a first agitating rib 51 and a second agitating rib 52. The first agitating rib 51 and the second agitating rib 52 are respectively connected to the scraping sections 54 on the left and right sides. The first agitating rib 51 is inclined downward along the rotation direction of the agitator 5. The first agitating rib 51 has a bent structure at the middle position along the radial direction. The inclination of the section of the first agitating rib 51 from the bent structure to the rotation shaft 53 is greater than the inclination of the section of the first agitating rib 51 from the bent structure to the scraping section 54. The second agitating rib 52 is arranged in the horizontal direction. The first agitating rib 51 and the second agitating rib 52 work together to stir and churn the liquid in the accommodating cavity, making the cooling effect more uniform.

[0069] The other end of the rotating shaft 53, which is connected to the drive device 7, is provided with a shaft positioning part 531. The accommodating cavity is provided with a cavity positioning part 55 corresponding to the shaft positioning part 531. The shaft positioning part 531 and the cavity positioning part 55 are respectively in the shape of corresponding arcs. The shaft positioning part 531 and the cavity positioning part 55 slide and cooperate with each other, which improves the stability of the stirrer 5 during rotation.

[0070] The accommodating cavity contains several ice-making trays 6, each containing several ice-condensing chambers 61 arranged in a grid pattern to hold liquid. The ice-making trays 6 are stacked vertically to form an ice tray assembly. A limiting mechanism is formed between vertically adjacent ice-making trays 6. The vertically adjacent ice-making trays 6 are detachable from each other and fixed horizontally by the limiting mechanism. The ice tray assembly formed by stacking ice-making trays 6 can better utilize the space inside the accommodating cavity, allowing for the formation of a relatively large number of ice-condensing chambers 61, increasing the amount of ice produced per refrigeration cycle. At the same time, the combination of ice-making trays 6 is relatively flexible and can adapt to more usage needs. Moreover, the limiting mechanism can improve the stability of the ice tray assembly structure, making it less likely for the ice tray assembly to disintegrate during the ice-making process.

[0071] Furthermore, the limiting mechanism includes an upper stop 62 and a lower stop 63 respectively disposed on the upper and lower sides of the ice-making tray 6. The lower stop 63 of the upper ice-making tray 6 abuts against the upper stop 62 of the lower ice-making tray 6 in the horizontal direction, and the upper stop 62 of the lower ice-making tray 6 abuts against the lower side of the upper ice-making tray 6 in the vertical direction. The installation structure between the upper and lower adjacent ice-making trays 6 is simple and has a good positioning effect.

[0072] Furthermore, the receiving cavity is cylindrical in shape, and the ice-making tray 6 has an arc surface 64 on the side away from the center of the receiving cavity. The arc surface 64 is concentric with the receiving cavity, which simplifies the action of aligning the ice-making tray 6 with the receiving cavity, making it easier for the user to place the ice-making tray 6 into the receiving cavity.

[0073] The cavity contains multiple sets of ice trays, with gaps between them allowing the stirrer 5 to pass through. Unused stirrers 5 and ice trays can be placed into the cavity at the same time, making it convenient to store the ice trays and stirrers 5.

[0074] The above embodiments are merely preferred embodiments of this utility model, and other implementations are also possible. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model, and all such equivalent modifications or substitutions are included within the scope set forth in the claims of this application.
