[0037] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0038] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, various specific examples of processes and materials are provided in this application; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0039] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0040] See Figure 1 and Figure 4 This application provides a portable refrigerator, including a refrigerator shell. Inside the refrigerator shell, a refrigeration area and a component installation area are formed side by side. The component installation area is provided with a battery pack 100 and a refrigeration component. The refrigeration component is located at the bottom of one side of the refrigerator shell, and the battery pack 100 is located above the refrigeration component. The refrigeration area is formed by an inner wall for containing and refrigerating items. The side of the inner wall near the component installation area does not overlap with the side of the refrigeration component and the battery pack 100 near the refrigeration area in the vertical direction.

[0041] Specifically, both the overall refrigeration area and the component installation area are square, dividing the interior of the refrigerator into two independent square structures, thereby maximizing the refrigeration area while meeting power supply and cooling requirements.

[0042] The portable refrigerator provided by this utility model integrates the battery pack 100 and the refrigeration component on the same side of the refrigerator, and arranges the battery pack 100 and the refrigeration component vertically, so that the area below the battery pack 100 can accommodate the refrigeration component. This makes full use of the vertical space inside the refrigerator shell, thus achieving an integrated design of the component installation area. Furthermore, since the side of the inner liner wall near the component installation area does not overlap vertically with the side of the refrigeration component and battery pack near the refrigeration area, compared with the existing refrigerator internal design, this utility model not only achieves the integration of the electrical components of the portable refrigerator, but also increases the usable space of the refrigeration area, thereby maximizing the refrigeration area of ​​the refrigerator and improving the space utilization rate of the refrigerator.

[0043] Specifically, the refrigeration components include a compressor 200, a radiator 201, and a condenser 202, which are arranged side-by-side below the battery pack 100. The compressor 200, radiator 201, and condenser 202 can be strategically arranged within the component installation area, allowing the inner wall of the refrigerator compartment near the component installation area to form a vertical surface, thus achieving no vertical overlap and maximizing the refrigerator's refrigeration area.

[0044] See Figure 2 The refrigerator housing includes at least one receiving slot 300 for receiving at least one battery pack 100. The opening of the receiving slot 300 communicates with the outside of the refrigerator housing, and the side wall of the battery pack 100 cooperates with the slot wall of the receiving slot 300 to achieve a detachable connection.

[0045] It should be noted that a receiving groove 300 is provided above the cooling component. The receiving groove 300 may have a certain degree of inclination relative to the vertical or horizontal direction to facilitate the insertion of the battery pack 100 and to limit the battery pack 100 to a certain extent.

[0046] Specifically, this application preferably has the depth of the receiving groove 300 parallel to the horizontal direction, or the depth of the receiving groove 300 parallel to the vertical direction, so that the total volume of the battery pack 100 can be maximized. Preferably, the shape of the battery pack 100 matches the shape of the receiving groove 300, so that when the battery pack 100 is arranged inside the receiving groove 300, the battery pack 100 and the receiving groove 300 fit together tightly.

[0047] In use, the battery pack 100 enters through the opening of the receiving slot 300, slides into the receiving slot 300 along the depth direction of the receiving slot 300, and fits tightly with the receiving slot 300 to realize the installation of the battery pack 100. At least one receiving slot 300 is provided to increase the battery capacity of the portable refrigerator and meet the user's need for long-lasting battery life of the portable refrigerator.

[0048] Furthermore, to simplify the process of replacing the battery pack 100, a quick-lock or magnetic device could be designed into the slot of the receiving slot 300, allowing users to install and remove the battery pack 100 more conveniently and quickly.

[0049] The side wall of the battery pack 100 is detachably connected to the wall of the receiving slot 300, enabling quick assembly and disassembly of the battery pack 100. The design of the receiving slot 300 also prevents the battery pack 100 from shaking freely inside the portable refrigerator, ensuring the overall stability of the portable refrigerator.

[0050] In another embodiment, at least one receiving slot 300 includes a first receiving slot and a second receiving slot. The portable refrigerator also includes a storage compartment 400, which includes a compartment body formed by five walls and has an opening 401 at the top. The first receiving slot can be used to receive the battery pack 100 or the storage compartment 400, and the second receiving slot can be used to receive the storage compartment 400 or the battery pack 100. The side wall of the storage compartment 400 cooperates with the slot wall of the first receiving slot and / or the second receiving slot to achieve a detachable connection. The side wall of the battery pack 100 cooperates with the slot wall of the first receiving slot and / or the second receiving slot to achieve a detachable connection.

[0051] Specifically, the preferred storage compartment 400 has a drawer-type structure with an opening 401 at the top. Since portable refrigerators are often used outdoors, there is a need for storage. When in use, users can store the portable refrigerator's charger or data cable and other miscellaneous items in the storage compartment 400 to improve the practicality of the portable refrigerator.

[0052] Specifically, the side wall of the storage compartment 400 can be designed the same as the side wall of the battery pack 100 so that both the storage compartment 400 and the battery pack 100 can be matched with the receiving slot 300 for replacement.

[0053] In use, users can install a battery pack 100 in the first and second storage compartments respectively, or install a battery pack 100 in the first storage compartment and a storage compartment 400 in the second storage compartment, thereby simultaneously meeting the needs for power supply and storage. Since both the battery pack 100 and the storage compartment 400 can be detachably connected to the storage compartment 300, it is very convenient to switch between these two usage modes. The portable refrigerator can meet a variety of application requirements.

[0054] Furthermore, to enhance the practicality of the storage compartment 400, dividers or storage compartments could be installed inside to allow users to better categorize and store items. Additionally, transparent windows or label slots could be added to the exterior of the storage compartment 400 to make it easier for users to identify and retrieve items.

[0055] This solution further enhances the functionality of the portable refrigerator, allowing users to store a wider variety of items as needed. Meanwhile, the detachable design of the storage compartment 400 makes it easy for users to adjust the internal layout of the refrigerator to suit different occasions.

[0056] To optimize the above technical solution, in one embodiment, the wall of the first receiving groove is provided with one of a first guide groove 302 and a first guide rib 301, and the side wall of the battery pack 100 is provided with the other of the first guide groove 302 and the first guide rib 301. The first guide groove 302 and the first guide rib 301 cooperate to engage the first receiving groove with the battery pack 100 or the storage compartment 400. In another embodiment, the wall of the second receiving groove is provided with one of a second guide groove 303 and a second guide rib, and the side wall of the storage compartment 400 is provided with the other of the second guide groove 303 and the second guide rib. The second guide groove 303 and the second guide rib cooperate to engage the second receiving groove with the storage compartment 400 or the battery pack 100. In another embodiment, both of the above structures may exist.

[0057] Specifically, taking the depth direction of the receiving groove 300 as the x-direction, a guide groove or guide rib is preferably set on the two sides symmetrically arranged with the x-direction as the axis, that is, the two groove walls of the receiving groove 300 arranged opposite each other. The side wall of the battery pack 100 is adapted to the shape of the two groove walls of the first receiving groove so that the side wall of the battery pack 100 can be just locked with the two groove walls of the first receiving groove. The side wall of the storage compartment 400 is adapted to the shape of the two groove walls of the second receiving groove so that the side wall of the storage compartment 400 can be just locked with the two groove walls of the second receiving groove.

[0058] Specifically, the extension direction of the guide groove or guide rib is parallel to the direction in which the battery pack 100 or the storage compartment 400 slides into the receiving groove 300, so as to improve the installation and disassembly efficiency of the battery pack 100 or the storage compartment 400.

[0059] When in use, the user inserts or removes the battery pack 100 or the storage compartment 400. The guide ribs move inside the guide groove, ensuring the accuracy and stability of the battery pack 100 and the storage compartment 400 during installation and removal, and reducing the difficulty of operation for the user.

[0060] To further enhance ease of installation, anti-slip or shock-absorbing materials can be added to the guide grooves and guide ribs to reduce friction and noise during installation. Additionally, positioning markers can be added to the guide grooves and guide ribs to help users install the battery pack 100 and storage compartment 400 more accurately.

[0061] See Figure 6To optimize the above technical solution, a second elastic arm 402 is provided on the side wall of the storage compartment 400. The first end of the second elastic arm 402 is connected to the side wall of the storage compartment 400, and the second end of the second elastic arm 402 is suspended. The second end of the second elastic arm 402 is provided with a first pressing protrusion. When the storage compartment 400 is received inside the second receiving groove, the first pressing protrusion abuts against the groove wall of the second receiving groove. And / or, a first elastic arm is provided on the side wall of the battery pack 100. The first end of the first elastic arm is connected to the side wall of the battery pack 100, and the second end of the first elastic arm is suspended. The second end of the first elastic arm is provided with a second pressing protrusion. When the battery pack 100 is received inside the first receiving groove, the second pressing protrusion abuts against the groove wall of the first receiving groove.

[0062] Specifically, the second elastic arm 402 can be disposed opposite to the two side walls of the storage compartment 400 to position the storage compartment 400 in two directions. The first elastic arm can be disposed opposite to the two side walls of the battery pack 100 to position the battery pack 100 in two directions. The second elastic arm 402 has the same structure as the first elastic arm. Through the elasticity of the elastic arm and the abutting action of the pressing protrusion, the storage compartment 400 or the battery pack 100 is firmly fixed in the receiving groove 300.

[0063] Specifically, the number, arrangement position, and length of the first elastic arm or the second elastic arm 402 can be adjusted according to the fastening requirements between the battery pack 100 or the storage compartment 400 and the receiving slot 300, so as to ensure the stability of the battery pack 100 or the storage compartment 400 and facilitate the user's disassembly and replacement.

[0064] In use, no other connectors are required. The battery pack 100 is tightly connected to the receiving slot 300 by the cooperation of the first guide groove 302 and the first guide rib 301, and by the clamping between the two first elastic arms. The storage compartment 400 is tightly connected to the receiving slot 300 by the cooperation of the second guide groove 303 and the second guide rib, and by the clamping between the two second elastic arms 402. This ensures that the battery pack 100 or the storage compartment 400 will not slip out of the receiving slot 300, making it safe and reliable. This saves installation space and improves the user experience.

[0065] Furthermore, anti-slip textures or rubber pads can be added to the press-up protrusions to improve their friction and anti-slip performance.

[0066] To optimize the above technical solution, the refrigerator casing includes a side panel 500 with an opening. At least one slot 300 has its opening communicating with the outside through the opening on the side panel 500. The portable refrigerator also includes a DC power supply assembly 600 and / or a photovoltaic panel assembly disposed inside the refrigerator casing. The DC power supply assembly 600 and / or the photovoltaic panel assembly are electrically connected to the battery pack 100. The respective connectors of the DC power supply assembly 600 and / or the photovoltaic panel assembly are located on the side panel 500 below the opening of the slot 300. A gripping part for holding and lifting the refrigerator is formed on the top of the side panel 500.

[0067] Specifically, the first receiving groove and the second receiving groove are arranged in parallel, and the openings of the first receiving groove and the second receiving groove are connected to the outside through the openings on the side plate 500. The DC power supply assembly 600 includes a DC power socket, and the photovoltaic panel assembly includes a photovoltaic panel socket. The DC power socket and the photovoltaic panel socket are electrically connected to the battery pack 100. The DC power socket and the photovoltaic panel socket are located on the side plate 500 and arranged below the opening of the receiving groove 300.

[0068] To optimize the above technical solution, the side of the battery pack 100 away from the refrigerator casing is provided with at least one of a universal serial bus 601, a DC interface, and an AC interface that are electrically connected to the battery pack 100.

[0069] Specifically, the battery pack 100 includes a connection terminal that is directly connected to the refrigerator's electrical device for powering the refrigerator. The DC power supply assembly 600 and / or photovoltaic panel assembly provide additional power input interfaces, increasing the ways in which the portable refrigerator can obtain power. The universal serial bus 601 can output power for user use.

[0070] This solution achieves stable power supply and flexible management through the modular design of the DC power supply component 600 and / or photovoltaic panel component and universal serial bus 601. At the same time, the multiple power supply units enhance product compatibility and scalability.

[0071] Furthermore, depending on usage needs, operators can add temperature sensors and a battery management system (BMS) to the battery pack to monitor battery temperature and status in real time and optimize the charging and discharging process. Additionally, adding wireless charging functionality can be considered to improve product convenience and ease of use.

[0072] Specifically, DC power sockets and photovoltaic panel sockets are used to provide additional power input methods besides batteries (connected to a DC power source or solar charging).

[0073] Specifically, the Universal Serial Bus (USB interface), including but not limited to USB interface, TYPE-C port, etc., can be used for charging and discharging to meet the power needs of users when using it outdoors.

[0074] In use, when the DC power supply component 600 and / or the photovoltaic panel component are in a powered state, the DC power supply component 600 and / or the photovoltaic panel component can directly supply power to the refrigerator to maintain its operation, and can also charge the battery pack 100. When the DC power supply component 600 and / or the photovoltaic panel component are charging the battery pack 100, the battery pack 100 can supply power to electronic products through the universal serial bus 601. When the DC power supply component 600 and / or the photovoltaic panel component are not in a powered state, the battery pack 100 directly supplies power to the refrigerator, and at this time the battery pack 100 can also simultaneously supply power to electronic products through the universal serial bus 601. When it is necessary to remove the battery pack 100 to act as a portable power source, it can be removed from the receiving slot 300 to supply power to electronic products anytime and anywhere. When the battery pack 100 itself is out of power, it can be removed from the receiving slot 300 for external charging.

[0075] This design enhances the refrigerator's power versatility and charging convenience, allowing users to choose different power sources to power the refrigerator as needed. Simultaneously, the inclusion of a USB port facilitates charging other devices, further improving the refrigerator's practicality and ease of use.

[0076] To optimize the above technical solution, the battery pack 100 is also provided with a screw cap 602, one end of which is rotatably connected to the battery pack 100, and the other end is detachably connected to the battery pack 100.

[0077] Specifically, the screw cap 602 is preferably made of silicone. The outer surface of the battery pack 100 has a groove for accommodating the screw cap 602. When the screw cap 602 is fastened in the groove, the universal serial bus 601 is in a closed state. When one end of the screw cap 602 is connected to the battery pack 100 and the other end is detached from the groove, the universal serial bus 601 is in an open state and can be used for charging.

[0078] When using the Universal Serial Bus 601 to charge electronic devices, there is no need to remove the battery pack 100 from the receiving slot 300. Simply rotate the cover 602 to expose the interface of the Universal Serial Bus 601, allowing users to enjoy a quick and convenient charging experience. When charging is complete, rotate the cover 602 again to close the interface, preventing dust from entering the interface and thus protecting the battery pack 100, achieving waterproof and dustproof protection for the USB interface.

[0079] This design improves the durability and security of the USB interface, extending the refrigerator's lifespan. At the same time, the screw cap 602 design allows users to quickly open and close the USB interface, enhancing ease of use.

[0080] To further enhance waterproof and dustproof performance, a sealing ring or waterproof adhesive could be installed at the connection between the screw cap 602 and the slot of the battery pack 100. Additionally, anti-slip textures or buttons could be incorporated into the screw cap 602 to facilitate easier opening and closing for users.

[0081] To optimize the above technical solution, the portable refrigerator also includes a display screen 700. The refrigerator shell includes a top cover 501. One end of the top cover 501 is vertically connected to the top of the side panel 500. The display screen 700 is fixed on the top cover 501 and located above the battery pack 100. The display screen 700 is electrically connected to the battery pack.

[0082] To optimize the above technical solution, the portable refrigerator also includes a moving component, which is fixed to the bottom of the portable refrigerator and close to the refrigeration component, and is used to move the portable refrigerator.

[0083] Specifically, within the space on one side of the refrigerator, the component installation area is arranged from top to bottom with a display screen 700, a battery pack 100, a refrigeration component, and a moving component, thereby achieving rational use of the refrigerator's internal space. Since the other side of the refrigerator is the refrigeration area, the refrigeration area is maximized, improving the refrigerator's space utilization rate.

[0084] Specifically, the display screen 700 is used to display information such as the refrigerator's operating status and temperature; the moving component is used to move the refrigerator, making it convenient for users to use in different situations.

[0085] Specifically, when the refrigerator is in operation, the compressor 200, radiator 201, condenser 202, display screen 700, etc. all require power. Fortunately, these electrical components are all located in the refrigerator's component installation area. The display screen 700 is located above the battery pack 100, while the compressor 200, radiator 201, and condenser 202 are located below the battery pack 100. In addition to facilitating power supply, the structural design of the refrigerator's component installation area makes better, fuller, and more rational use of the refrigerator's internal space.

[0086] Specifically, the moving component includes a moving wheel 800 and a support shaft. A moving wheel 800 is connected to each end of the support shaft. The refrigerator shell includes a first side 502 and a second side 504 arranged opposite to each other. One side of the first side 502 is connected to the top cover 501 and the other side is connected to the side plate 500. One side of the second side 504 is connected to the top cover 501 and the other side is connected to the side plate 500. The two ends of the support shaft are rotatably connected to the first side 502 and the second side 504 respectively. Both the first side 502 and the second side 504 are provided with a protrusion 503 for accommodating the moving wheel 800.

[0087] Specifically, the groove 503 is positioned below the refrigeration unit to prevent steps or protrusions from appearing in the refrigeration area, ensuring that the refrigeration area has a vertical inner wall from top to bottom.

[0088] This solution further integrates the display screen 700 and the moving components into the component installation area, thereby making full use of the space in the refrigerator component installation area and improving the space utilization rate of the refrigerator.

[0089] See Figure 5 To optimize the above technical solution, the battery pack 100 includes a handle 101, and the battery pack 100 includes a first sidewall 103 and a second sidewall disposed opposite to each other. The two ends of the handle 101 are rotatably connected to the first sidewall 103 and the second sidewall, respectively. A first handle position 102 is provided in the middle of the handle 101. And / or, the storage compartment 400 includes a second handle position 403, which is disposed on the top of the storage compartment 400. And / or, the storage compartment 400 includes a groove 404, which is formed in the sidewall of the storage compartment 400. The first handle position 102, the second handle position 403 and the groove 404 are used for users to hold.

[0090] Specifically, the first handle position 102 protrudes from the handle 101, making it easier for the user to hold the handle 101. Since the top of the storage compartment 400 has an opening 401, the second handle can be set on the top of the end face of the storage compartment 400 away from the side panel 500 and protrude from the top of this end face.

[0091] Specifically, the groove 404 can be formed on the opposite two side walls connected to the end face of the storage compartment 400 away from the side plate 500, or it can be formed on the bottom of the end face of the storage compartment 400 away from the side plate 500, or it can be formed on both the side walls and the bottom. When in use, the user puts his hand into and holds the groove 404. The arrangement and shape design of the groove 404 should make it easy for the user to hold the storage compartment 400 from various angles.

[0092] Specifically, when the battery pack 100 is installed in the preset position, the handle 101 is placed against the outer surface of the battery pack 100 for storage.

[0093] This design simplifies the process of installing and removing the storage compartment 400 or the battery pack 100, reducing operational difficulty. At the same time, the design of the handle 101 and the latch position also improves the practicality and convenience of the storage compartment 400 or the battery pack 100, allowing users to easily push and pull the storage compartment 400 into the second receiving slot and the battery pack 100 into the first receiving slot using various gestures. This facilitates the storage compartment 400 and the battery pack 100 being easily stored and retrieved from the receiving slot 300, enhancing the user experience.

[0094] To further enhance portability and ease of use, anti-slip textures or rubber pads could be added to the handle 101 and the grip area to improve grip and comfort.

[0095] See Figure 3 To optimize the above technical solution, the portable refrigerator also includes a battery cover 801 with an opening. The battery cover 801 is detachably or rotatably covered on the opening of the side panel 500. When the battery cover 801 is covered on the side panel 500, the screw cap 602 can extend outward through the opening or be at least partially stored in the opening.

[0096] To optimize the above technical solution, the side panel 500 includes a recess. When the battery pack 100 is disposed inside the receiving groove 300, the end of the battery pack 100 away from the refrigerator shell protrudes from the recess. The recess is a structural form of an opening in the side panel 500.

[0097] Specifically, when the battery pack 100 is arranged inside the first receiving groove and the storage compartment 400 is arranged inside the second receiving groove, the ends of the battery pack 100 and the storage compartment 400 away from the refrigerator shell protrude from the recess. However, in the vertical direction, viewed from top to bottom, the ends of the battery pack 100 and the storage compartment 400 away from the refrigerator shell are on the same straight line as the rest of the side panel 500 except for the recess. Alternatively, the recess can hide the ends of the battery pack 100 and the storage compartment 400 away from the refrigerator shell, preventing the battery pack 100 and the storage compartment 400 from protruding from the side panel 500, thereby protecting the battery pack 100 and the storage compartment 400.

[0098] Specifically, after the battery pack 100 or the storage compartment 400 is placed inside the first and second receiving compartments respectively, the battery cover 801 is connected to the sealing plate to further protect the battery pack 100 and the storage compartment 400. At the same time, the battery cover 801 can seal the above-mentioned recessed part, further ensuring the installation stability of the battery pack 100, preventing dust or moisture from entering the receiving compartment 300, and improving the hygiene and aesthetics of the refrigerator.

[0099] To further enhance the installation stability and dust and water resistance of the battery pack 100, a sealing ring or waterproof adhesive could be installed at the connection between the battery cover 801 and the side panel 500. Additionally, a locking or snap-fit ​​device could be added to the battery cover 801 to allow users to securely fasten it.

[0100] It should be noted that the top of the battery cover 801 is provided with a flexible buckle 802, and the side plate 500 is provided with a latching hole 803. In use, the flexible buckle 802 is installed inside the latching hole 803, and the top of the flexible buckle 802 is engaged with the edge of the latching hole 803. When it is necessary to remove the battery cover 801, the operator presses the flexible buckle 802 vertically, the flexible buckle 802 deforms, and the top of the buckle is no longer engaged with the edge of the latching hole 803, so that the battery cover 801 can be removed.

[0101] Furthermore, the bottom of the battery cover 801 is provided with a plug-in block, and the corresponding position of the side plate 500 is provided with a plug-in hole 804 that can be plugged into and connected to the plug-in block. The plug-in block and the plug-in hole 804 are plugged into each other in the vertical direction to fix the bottom of the battery cover 801.

[0102] This arrangement allows the battery cover 801 to be securely installed on the side panel 500, making it less likely to be lost, thus ensuring the stability and safety of the battery pack 100 or storage compartment 400.

[0103] Furthermore, the edge of the top cover 501 is integrated with a rotating component 5011, which is rotatably connected to the edge of the top cover 501. In use, the operator can open or close the refrigeration area by pressing the rotating component 5011.

[0104] Furthermore, a bottle opener 5012 is integrated on the first side 502 or the second side 504. The edge of the main body of the bottle opener 5012 is rotatably connected to the first side 502 or the second side 504. When the bottle needs to be opened, the main body of the bottle opener 5012 is rotated out and has a certain angle with the first side 502 or the second side 504 to facilitate the bottle opening operation. When the bottle does not need to be opened, the main body of the bottle opener 5012 is fitted into the first side 502 or the second side 504 for storage.
