[Modes for carrying out the invention]

[0029] To clarify the purpose, technical configuration, and advantages of the embodiments of this application, the technical configuration of the embodiments will be described clearly and completely below with reference to the drawings relating to the embodiments of this application. Note that the embodiments described herein represent only some, not all, embodiments of this application. All other embodiments that a person skilled in the art can obtain without creative effort based on the embodiments of this application are within the scope of protection of this application.

[0030] The following disclosure provides numerous different embodiments or examples for realizing various configurations of this application. For the sake of brevity of the disclosure, the components and their arrangement in specific examples are described below, but these are for illustrative purposes only and are not intended to limit this application. In addition, the same reference numerals and / or letters may be used repeatedly in different examples in this application, but such repetition is for the purpose of simplifying and clarifying the explanation and does not in itself indicate a relationship between each embodiment and / or configuration. Furthermore, while examples of specific processes and materials are shown in this application, those skilled in the art will readily understand the applicability of other processes and / or the use of other materials.

[0031] To facilitate explanation, terms indicating spatial relationships may be used herein when describing the relative positional relationship or motion state of one component or feature shown in the drawings relative to other components or features. Examples of these terms indicating spatial relationships include "internal," "external," "inside," "outside," "bottom," "below," "top," "upward," "front," and "back." These terms indicating spatial relationships are not limited to the orientation shown in the drawings, but are intended to include different orientations when the device is in use or operating. For example, if the device shown in the drawings is inverted, its orientation changes, or its motion state changes, the description indicating the orientation will be interpreted to change accordingly. That is, a component described as "located below another component or feature" or "located below another component or feature" may be interpreted as "located above another component or feature" or "located above another component or feature" in subsequent orientations. Therefore, the exemplary term "below ~" may include both upward and downward positional relationships. Furthermore, the apparatus may be positioned in other directions (for example, rotated by 90 degrees), and any descriptions of spatial relative relationships used herein shall be interpreted in accordance with such arrangements.

[0032] Referring to Figures 1 and 4, an embodiment of the present application provides a portable refrigerator, which includes a refrigerator housing 50. Inside the refrigerator housing 50, a refrigeration area and an assembly mounting area are formed side by side and adjacent to each other. A battery assembly 10 and a refrigeration assembly are provided in the assembly mounting area, the refrigeration assembly being located at the bottom of one side of the refrigerator housing 50, and the battery assembly 10 being located above the refrigeration assembly. The refrigeration area is formed by being surrounded by an inner box wall for accommodating and refrigerating articles. The side of the inner box wall adjacent to the assembly mounting area and the sides of the refrigeration assembly and the battery assembly 10 adjacent to the refrigeration area do not overlap each other in the vertical direction.

[0033] Specifically, both the entire refrigeration area and the entire assembly mounting area are rectangular in shape, thereby dividing the inside of the refrigerator into two independent rectangular structures. This configuration maximizes the refrigeration area under conditions that satisfy power supply and cooling requirements.

[0034] The portable refrigerator according to this application integrates the battery assembly 10 and the refrigeration assembly on the same side of the refrigerator, and employs a configuration in which the battery assembly 10 and the refrigeration assembly are positioned vertically, one above the other. This makes it possible to position the refrigeration assembly in the area below the battery assembly 10, allowing for effective use of the vertical space within the refrigerator housing 50 and realizing a consolidated design for the assembly mounting area. Furthermore, since the side of the inner box wall adjacent to the assembly mounting area and the side of the refrigeration assembly and the battery assembly 10 adjacent to the refrigerated area do not overlap each other vertically, compared to the internal structure of conventional refrigerators, this application not only realizes the consolidation of electrical components in a portable refrigerator but also expands the usable space of the refrigerated area. This maximizes the refrigerated area of ​​the refrigerator and improves the space utilization rate of the refrigerator.

[0035] Specifically, the refrigeration assembly includes a compressor 200, a heat sink 201, and a condenser 202, which are arranged side-by-side below the battery assembly 10. By rationally arranging the compressor 200, heat sink 201, and condenser 202 within the assembly mounting area, the side of the inner box wall of the refrigerated area adjacent to the assembly mounting area can form a vertical plane, avoiding vertical overlap and thereby maximizing the refrigerated area of ​​the refrigerator. Furthermore, because the compressor 200, heat sink 201, and condenser 202 are arranged side-by-side below the battery assembly 10, the battery assembly 10 is positioned above the compressor 200, heat sink 201, and condenser 202. Moreover, since the battery assembly 10, compressor 200, heat sink 201, and condenser 202 are all located on the same side of the portable refrigerator, the arrangement of the internal space of the portable refrigerator is optimized.

[0036] In some embodiments, referring to Figures 5 and 7, the heat sink 201 includes a fan 2011 and a sealing member 2012. The compressor 200, fan 2011, and condenser 202 are arranged side by side inside the refrigerator housing 50, thereby forming a heat dissipation air passage. The sealing member 2012 is connected to the inner wall of the housing of the heat dissipation air passage, which is surrounded by the outer shell of the fan 2011 and the refrigerator housing 50, thereby forming a single air passage between the compressor 200 and the condenser 202. That is, the airflow formed by the fan 2011 is controlled to flow through the gaps between the blades of the fan 2011 from one end where the condenser 202 is located to the other end where the compressor 200 is located, thereby achieving rapid heat dissipation.

[0037] Specifically, preferably, the sealing member 2012 is made of EVA material (ethylene-vinyl acetate copolymer). The sealing member 2012 is connected to the inner wall of the housing of the heat dissipation air passage surrounded by the outer shell of the fan 2011 and the refrigerator housing 50, thereby forming an EVA isolation wall. This isolation wall controls the airflow to flow in one direction within the heat dissipation duct, forming a single airflow path.

[0038] During use, the fan 2011 is positioned between the high-temperature compressor 200 and condenser 202. When the fan 2011 generates airflow, the airflow flows rapidly from one side of the EVA isolation wall to the other, forming a single heat dissipation airway. This allows the heat generated from the compressor 200 to be quickly discharged to the outside, promoting heat dissipation from the compressor 200 and condenser 202, and improving the freezing capacity of the portable refrigerator.

[0039] This arrangement allows the compressor 200, condenser 202, fan 2011, and sealing member 2012 to be integrated inside the refrigerator casing 50, improving the heat dissipation efficiency and operational stability of the portable refrigerator, while also saving structural space.

[0040] Furthermore, a filter can be added to the intake side of fan 2011, which prevents dust and foreign matter from contaminating the compressor 200 or condenser 202.

[0041] Referring to Figure 2, the refrigerator housing 50 includes at least one housing groove 30, which is used to house at least one battery assembly 10. The groove opening of the housing groove 30 communicates with the outside of the refrigerator housing 50. The battery assembly 10 includes a battery pack, and a detachable connection is achieved by the side wall of the battery pack engaging with the groove wall of the housing groove 30.

[0042] Furthermore, a storage groove 30 is provided above the refrigeration assembly, and the storage groove 30 may be configured to have a predetermined inclination angle with respect to the vertical or horizontal direction. This makes it easier to insert the battery pack and also allows for a certain degree of positional control over the battery pack.

[0043] Specifically, in this application, preferably, the groove depth of the housing groove 30 is parallel to the horizontal direction, or the groove depth of the housing groove 30 is parallel to the vertical direction. This makes it possible to maximize the total volume of the battery pack. Preferably, the shape of the battery pack conforms to the shape of the housing groove 30. When the battery pack is placed inside the housing groove 30, the battery pack and the housing groove 30 are tightly fitted together.

[0044] During use, the battery pack is inserted through the groove opening of the housing groove 30 and positioned within the housing groove 30 by sliding along the groove depth direction, thereby fitting tightly with the housing groove 30 and achieving battery pack installation. At least one housing groove 30 is provided, which makes it possible to increase the battery capacity of the portable refrigerator and meet the user's demand for extended use.

[0045] Furthermore, to simplify the battery pack replacement process, a quick-lock mechanism or magnetic adsorption mechanism may be provided at the opening of the storage groove 30. This would allow the user to install and remove the battery pack more easily and quickly.

[0046] The side walls of the battery pack are detachably connected to the groove walls of the housing groove 30, enabling quick attachment and detachment of the battery pack. Furthermore, the configuration of the housing groove 30 prevents the battery pack from unintentionally shaking inside the portable refrigerator, ensuring the overall stability of the portable refrigerator.

[0047] In another embodiment, at least one housing groove 30 includes a first housing groove 31 and a second housing groove 32 that are arranged side by side and spaced apart. As shown in Figure 11, the portable refrigerator further includes a housing 400, which includes a housing body surrounded by five walls and having an opening 401 at the top. The first housing groove 31 is capable of accommodating a battery pack or the housing 400, and the second housing groove 32 is capable of accommodating the housing 400 or a battery pack. Furthermore, the side walls of the housing 400 are detachably connected by engaging with the groove walls of the first housing groove 31 and / or the second housing groove 32, and the side walls of the battery pack are detachably connected by engaging with the groove walls of the first housing groove 31 and / or the second housing groove 32.

[0048] Specifically, preferably, the storage compartment 400 has a drawer-type structure and an opening 401 at the top. Since portable refrigerators are often used outdoors, there is a need for storage of items. When in use, the user can store small items such as the portable refrigerator's charger and data cable inside the storage compartment 400, thereby improving the practicality of the portable refrigerator.

[0049] Specifically, the side walls of the storage compartment 400 can be designed to be identical to the side walls of the battery pack, so that both the storage compartment 400 and the battery pack fit into the storage groove 30 and can be used interchangeably.

[0050] During use, the user can place one battery pack in each of the first storage groove 31 and the second storage groove 32, or place a battery pack in the first storage groove 31 and a storage compartment 400 in the second storage groove 32, depending on the purpose of use. This makes it possible to simultaneously meet the demands for power supply and storage. Since both the battery pack and the storage compartment 400 are detachably connected to the storage groove 30, switching between these two usage states is extremely easy, and the portable refrigerator can accommodate a variety of usage scenarios and application requirements.

[0051] Furthermore, to enhance the practicality of the storage compartment 400, it is conceivable to provide partitions or storage compartments inside the compartment 400, thereby allowing the user to classify and store items more appropriately. Additionally, it is conceivable to provide a transparent viewing window or label slots on the outside of the storage compartment 400, thereby allowing the user to easily identify and retrieve the stored items.

[0052] This configuration further enhances the functionality of the portable refrigerator, allowing users to store a wider variety of items depending on their intended use. Furthermore, since the storage compartment 400 is removable, users can flexibly adjust the internal layout of the refrigerator according to their needs, adapting to various situations.

[0053] To optimize the above technical solution, in one embodiment, referring to Figures 2, 10, and 11, the groove wall of the first housing groove 31 is provided with one of the first guide groove 302 and the first guide rib 301, and the side wall of the battery pack or the side wall of the housing 400 is provided with the other of the first guide groove 302 and the first guide rib 301. The first housing groove 31 and the battery pack or housing 400 are locked together by the engagement of the first guide groove 302 and the first guide rib 301 with each other. In another embodiment, the groove wall of the second housing groove 32 is provided with one of the second guide groove 303 and the second guide rib, and the side wall of the housing 400 or the side wall of the battery pack is provided with the other of the second guide groove 303 and the second guide rib. The second housing groove 32 and the housing 400 or battery pack are locked together by the engagement of the second guide groove 303 and the second guide rib with each other. In yet another embodiment, the two configurations described above can coexist, namely, one of the guide grooves and guide ribs is provided in both the first storage groove 31 and the second storage groove 32, and the other of the guide grooves and guide ribs is provided in both the side wall of the battery pack and the side wall of the storage compartment 400.

[0054] Specifically, if the groove depth direction of the housing groove 30 is the x-direction, then preferably, guide grooves or guide ribs are provided on both sides that are symmetrical with respect to the x-direction, i.e., on two groove walls that are opposite each other in the housing groove 30. The side walls of the battery pack are configured to conform to the shape of both groove walls of the first housing groove 31, so that the side walls of the battery pack can engage with both groove walls of the first housing groove 31. Similarly, the side walls of the storage compartment 400 are configured to conform to the shape of both groove walls of the second housing groove 32, so that the side walls of the storage compartment 400 can engage with both groove walls of the second housing groove 32.

[0055] Specifically, the direction in which the guide groove or guide rib extends is set parallel to the direction in which the battery pack or housing 400 slides into the housing groove 30. This improves the efficiency of installing and removing the battery pack or housing 400.

[0056] During use, the guide ribs move within the guide grooves as the user inserts or removes the battery pack or storage compartment 400. This ensures precision and stability during the installation and removal of the battery pack and storage compartment 400, and reduces the user's operational burden.

[0057] Furthermore, to further enhance the convenience of installation, it is conceivable to provide anti-slip material or vibration-damping material in the guide grooves and guide ribs, thereby reducing friction and noise during the installation process. It is also conceivable to provide positioning indicators in the guide grooves and guide ribs, thereby enabling the user to install the battery pack and storage compartment 400 more accurately.

[0058] Referring to Figure 11, in order to 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, the second end of the second elastic arm 402 is provided as a free end, and a first pressing projection is provided on the second end of the second elastic arm 402. When the storage compartment 400 is housed inside the second housing groove 32, the first pressing projection abuts against the groove wall of the second housing groove 32. And / or, a first elastic arm is provided on the side wall of the battery pack. The first end of the first elastic arm is connected to the side wall of the battery pack, the second end of the first elastic arm is provided as a free end, and a second pressing projection is provided on the second end of the first elastic arm. When the battery pack is housed inside the first housing groove 31, the second pressing projection abuts against the groove wall of the first housing groove 31.

[0059] Specifically, the second elastic arm 402 may be provided opposite both side walls of the storage compartment 400, thereby enabling positioning of the storage compartment 400 in two directions. Similarly, the first elastic arm may be provided opposite both side walls of the battery pack, thereby enabling positioning of the battery pack in two directions. The second elastic arm 402 and the first elastic arm have the same structure, and the storage compartment 400 or the battery pack is securely fixed within the storage groove 30 by the elastic action of the elastic arm and the contact action of the pressing projection.

[0060] Specifically, the number, position, and length of the first or second elastic arms 402 can be adjusted as needed to ensure the fastening between the battery pack or housing 400 and the housing groove 30. This allows for easy removal and replacement by the user while ensuring the stability of the battery pack or housing 400.

[0061] During use, the battery pack is tightly connected to the housing groove 30 solely by the engagement of the first guide groove 302 and the first guide rib 301, and by clamping with the two first elastic arms, without the use of any other connecting members. On the other hand, the housing 400 is tightly connected to the housing groove 30 solely by the engagement of the second guide groove 303 and the second guide rib, and by clamping with the two second elastic arms 402. This ensures safety and reliability by preventing the battery pack or housing 400 from accidentally slipping out of the housing groove 30.

The direction of protrusion of the mis-installation prevention projection is parallel to the installation direction of the battery pack, and the engagement between the mis-installation prevention projection and the mis-installation prevention recess ensures stable mounting of the battery pack.

[0069] To optimize the above technical solution, referring to Figures 1 and 2, the refrigerator housing 50 includes a side plate 500 in which an opening is formed. At least one groove opening of a housing groove 30 communicates with the outside through an opening formed in the side plate 500. The portable refrigerator further includes a DC power supply assembly 600 and / or a photovoltaic panel assembly provided inside the refrigerator housing, the DC power supply assembly 600 and / or the photovoltaic panel assembly being electrically connected to a battery pack, respectively. Each insertion opening for the DC power supply assembly 600 and / or the photovoltaic panel assembly is located below the groove opening of the housing groove 30 in the side plate 500.

[0070] Specifically, the first housing groove 31 and the second housing groove 32 are arranged in parallel, and the groove openings of the first housing groove 31 and the second housing groove 32 communicate with the outside through openings formed in the side plate 500. The DC power supply assembly 600 includes a socket for the DC power supply, and the photovoltaic panel assembly includes a socket for the photovoltaic panel. The DC power supply socket and the photovoltaic panel socket are electrically connected to the battery pack. The DC power supply socket and the photovoltaic panel socket are provided on the side plate 500 and are positioned below the groove openings of the housing groove 30.

[0071] To optimize the above technical solution, referring to Figure 3, the battery assembly 10 further includes an output interface 601. The output interface 601 is located on the outward-facing side of the side plate 500 of the battery pack and is electrically connected to the battery pack. The output interface 601 includes at least one of a universal serial bus interface, a DC interface, and an AC interface.

[0072] Specifically, the battery pack body includes a connection terminal, which is directly connected to the refrigerator's power consumption device and used to supply power to the refrigerator. The DC power supply assembly 600 and / or the solar panel assembly can provide an additional power input interface, thereby expanding the means by which the portable refrigerator obtains power. The output interface 601 can also output power externally, making it available for the user to use.

[0073] Specifically, if the battery assembly 10 includes a first battery pack 11 and a second battery pack 12, the battery assembly 10 further includes a first output interface and a first rotating cover corresponding to the first battery pack 11. The first output interface is provided on the outward-facing side of the side plate 500 of the first battery pack 11 and is electrically connected to the first battery pack 11. One end of the first rotating cover is rotatably connected to the first battery pack 11, and the other end is lockably connected to the first battery pack 11. And / or, the battery assembly 10 further includes a second output interface and a second rotating cover corresponding to the second battery pack 12. The second output interface is provided on the outward-facing side of the side plate 500 of the second battery pack 12 and is electrically connected to the second battery pack 12. One end of the second rotating cover is rotatably connected to the second battery pack 12, and the other end is lockably connected to the second battery pack 12.

[0074] In this configuration, the DC power supply assembly 600 and / or the photovoltaic panel assembly and the output interface 601 are designed as modules, thereby achieving stable power supply and flexible power management. Furthermore, the inclusion of multiple power supply units improves product compatibility and expandability.

[0075] Furthermore, depending on usage requirements, a temperature sensor and battery management system (BMS) can be added inside the battery pack, enabling real-time monitoring of the battery pack's temperature and status, and optimization of the charging and discharging processes. Adding wireless charging functionality is also conceivable, further improving the product's convenience and ease of use.

[0076] Specifically, the DC power socket and the solar panel socket are used to provide additional power input means other than the battery pack. For example, power can be supplied by connecting to a DC power source via the DC power socket, or charging can be performed using solar energy via the solar panel socket.

[0077] Specifically, the output interface 601 includes, but is not limited to, a USB interface or a Type-C port. The output interface 601 can be used for both charging and discharging, and can meet the user's power needs when used outdoors.

[0078] When in use, if the DC power supply assembly 600 and / or the solar panel assembly are powered, they can directly supply power to the refrigerator to maintain its operation and can also charge the battery pack. When the DC power supply assembly 600 and / or the solar panel assembly are charging the battery pack, the battery pack can supply power to electronic devices via the output interface 601. If the DC power supply assembly 600 and / or the solar panel assembly are not powered, the battery pack will directly supply power to the refrigerator, and in this case, the battery pack can also simultaneously supply power to electronic devices via the output interface 601. Furthermore, if the battery pack needs to be used as a mobile power source, it can be removed from the housing groove 30 and used to supply power to electronic devices at any location. In addition, if the battery pack's charge level is low, it can be removed from the housing groove 30 and externally charged.

[0079] This configuration improves the versatility of power sources and charging convenience for the refrigerator, allowing users to select different power supply methods depending on their usage. Furthermore, the inclusion of output interface 601 makes it easier for users to charge other devices, further enhancing the practicality and convenience of the refrigerator.

[0080] To optimize the above technical solution, referring to Figures 1 and 10, the battery assembly 10 further includes a rotating cover 602. One end of the rotating cover 602 is rotatably connected to the battery pack, and the other end is attachably connected to the battery pack.

[0081] Specifically, preferably, the rotating cover 602 is made of silicone material. A groove for accommodating the rotating cover 602 is formed on the outer surface of the battery pack, and when the rotating cover 602 is locked in the groove, the outer surface of the battery pack has a smooth appearance. In this state, the rotating cover 602 seals the output interface 601, and the output interface 601 is closed, so that moisture or sand particles can not enter the output interface 601 when used outdoors. On the other hand, when one end of the rotating cover 602 remains connected to the battery pack and the other end is out of the groove, the output interface 601 is open and can be used for charging.

[0082] When using the device, if it is necessary to charge an electronic device using the output interface 601, the battery pack can be exposed simply by rotating the rotating cover 602 without removing it from the housing groove 30. This allows the user to perform charging operations quickly and easily, providing a convenient charging experience. After charging is complete, the rotating cover 602 can be rotated again to seal the output interface 601, preventing dust from entering the output interface 601, protecting the battery pack, and ensuring the waterproof and dustproof properties of the output interface 601.

[0083] This configuration improves the durability and safety of the output interface 601, extending the refrigerator's lifespan. Furthermore, the design of the rotating lid 602 allows users to quickly open and close the output interface 601, further enhancing convenience during use.

[0084] Furthermore, to further improve water and dust resistance, it is conceivable to provide a sealing ring or waterproof sealant at the connection point between the rotating cover 602 and the groove in the battery pack. In addition, it is conceivable to provide the rotating cover 602 with a non-slip surface or a button or other structure, which would allow the user to open and close the rotating cover 602 more easily.

[0085] To optimize the above technical solution, referring to Figure 1, the portable refrigerator further includes a display 700. The refrigerator housing 50 includes a top lid 501, one end of which is vertically connected to the top of the side panel 500. The display 700 is fixed to the top lid 501 and positioned above the battery pack. The display 700 is also electrically connected to the battery pack.

[0086] To optimize the above technical solution, the portable refrigerator further includes a mobile assembly. The mobile assembly is fixed to the bottom of the portable refrigerator and positioned close to the freezing assembly, and is used to move the portable refrigerator. This improves the portability of the refrigerator.

[0087] Specifically, in the space on one side of the refrigerator, the assembly mounting area is arranged from top to bottom with the display 700, battery pack, refrigeration assembly, and mobile assembly. This enables rational use of the refrigerator's internal space. On the other hand, the other side of the refrigerator is configured as the refrigeration area, maximizing the refrigeration area and improving the overall space utilization efficiency of the refrigerator.

[0088] Specifically, the display 700 is used to display information such as the operating status and temperature of the refrigerator. The mobile assembly is used to move the refrigerator, allowing users to easily use it in different situations.

[0089] Specifically, when the refrigerator is powered on, various electrical components such as the compressor 200, radiator 201, condenser 202, and display 700 require power. All of these electrical components are located in the refrigerator's assembly mounting area, with the display 700 positioned above the battery pack, and the compressor 200, radiator 201, and condenser 202 positioned below the battery pack. This arrangement facilitates power supply, streamlines the structural design of the assembly mounting area, and allows for more effective and efficient use of the refrigerator's internal space.

[0090] Specifically, referring to Figures 1 and 2, the mobile assembly includes a mobile wheel 800 and a support shaft 807. One mobile wheel 800 is connected to each end of the support shaft 807, and the mobile assembly is used to move the portable refrigerator by the two mobile wheels 800. Also referring to Figures 1 to 4, the refrigerator housing 50 includes a first side 502 and a second side 504 that are positioned opposite each other. One side of the first side 502 is connected to the top lid 501 and the other side is connected to the side plate 500, and one side of the second side 504 is connected to the top lid 501 and the other side is connected to the side plate 500. Both ends of the support shaft 807 are rotatably connected to the first side 502 and the second side 504, respectively. The first side 502 and the second side 504 are each provided with a protruding groove 503, which is used to accommodate the mobile wheel 800.

[0091] Specifically, the protruding groove 503 is positioned corresponding to the lower part of the refrigeration assembly. This prevents the formation of steps or protrusions within the refrigerated area, resulting in a structure where the refrigerated area has a continuous vertical inner wall from the top to the bottom.

[0092] This configuration further integrates the display 700 and the mobile assembly into the assembly mounting area, making effective use of the space in the refrigerator's assembly mounting area. As a result, the overall space utilization efficiency of the refrigerator is improved.

[0093] Referring to Figures 10 and 11, to optimize the above technical solution, the battery pack includes a handle 101. The battery pack includes a first side wall 103 and a second side wall that are positioned opposite each other, and both ends of the handle 101 are rotatably connected to the first side wall 103 and the second side wall, respectively. A first gripping portion 102 is also provided in the center of the handle 101. And / or, the storage compartment 400 includes a second gripping portion 403, which is provided at the top of the storage compartment 400. And / or, the storage compartment 400 includes a groove 404, which is formed in the side wall of the storage compartment 400. The first gripping portion 102, the second gripping portion 403 and the groove 404 are used for the user to grip.

[0094] Specifically, the first gripping portion 102 is provided to protrude from the handle 101, thereby making it easier for the user to grasp the handle 101. In addition, since an opening 401 is formed at the top of the storage compartment 400, the second gripping portion 403 is provided at the top of the end face of the storage compartment 400, away from the side plate 500, and can protrude from the top of that end face.

[0095] Specifically, the grooves 404 can be formed on opposing side walls connected to the end faces of the storage compartment 400 away from the side plates 500, or on the bottom of the end faces of the storage compartment 400 away from the side plates 500, or they can be formed on both the side walls and the bottom. When in use, the user can insert their hand and grasp the grooves 404, and the position and shape of the grooves 404 are designed to make it easy for the user to grasp the storage compartment 400 from various directions.

[0096] Specifically, when the battery pack is installed in the storage groove 30, the handle 101 is stored so as to be in close contact with the outer surface of the battery pack.

[0097] This configuration simplifies the user's operation when installing or removing the storage compartment 400 or battery pack, reducing the burden on the user. Furthermore, the design of the handle 101 and gripping part improves the practicality and convenience of the storage compartment 400 or battery pack, allowing the user to push and pull the storage compartment 400 within the second storage groove 32 and the battery pack within the first storage groove 31 using various hand movements. This makes it easier to store or remove the storage compartment 400 and battery pack from the storage groove 30, improving the user experience.

[0098] Furthermore, to further improve portability and operability, it is conceivable to provide the handle 101 and gripping portion with anti-slip textured surfaces or materials such as rubber pads. This would improve gripping strength and comfort during use.

[0099] Referring to Figure 3, in order to optimize the above technical solution, the portable refrigerator further includes a battery cover 801 in which an opening is formed. The battery cover 801 is removablely or rotatably fitted over the opening in the side plate 500. With the battery cover 801 fitted over the side plate 500, the rotatable cover 602 can protrude outward through the opening, or at least a portion of it is housed within the opening.

[0100] Referring to Figures 1 and 9, in order to optimize the above technical solution, the side plate 500 is further provided with an inner recess 505 that is recessed toward the inside of the refrigerator housing 50. At least one housing groove 30 is formed in the inner recess 505. When the battery pack is placed inside the housing groove 30, one end of the battery pack that is away from the refrigerator housing 50 protrudes from the inner recess 505. The inner recess 505 constitutes one form of an opening formed in the side plate 500.

[0101] Specifically, the battery cover 801 and the inner recess 505 can be detachably connected by connection methods such as plug-in connections and locking connections. Furthermore, the battery cover 801 and the inner recess 505 can also be rotatably connected by connection methods such as a rotating shaft connection.

[0102] Specifically, when the battery pack is positioned inside the first housing groove 31 and the storage compartment 400 is positioned inside the second housing groove 32, the ends of the battery pack and storage compartment 400 that are away from the refrigerator casing 50 protrude from the inner recess 505. In this case, when viewed from above to below in the vertical direction, the ends of the battery pack and storage compartment 400 that are away from the refrigerator casing 50 are aligned in a straight line with the other parts of the side plate 500 excluding the inner recess 505. Alternatively, the inner recess 505 can shield the ends of the battery pack and storage compartment 400 that are away from the refrigerator casing 50, thereby preventing the battery pack and storage compartment 400 from protruding from the side plate 500 and protecting the battery pack and storage compartment 400.

[0103] Specifically, after the battery pack or storage compartment 400 is placed inside the first storage groove 31 and the second storage groove 32, respectively, the battery cover 801 is connected to the side plate 500, further protecting the battery pack and storage compartment 400. At the same time, the battery cover 801 can seal the internal recess 505, thereby further ensuring the stability of the battery pack's mounting. In addition, it prevents dust or moisture from entering the storage groove 30, improving the hygiene and appearance of the refrigerator.

[0104] Furthermore, to further improve the mounting stability and dustproof / waterproof properties of the battery pack, it is conceivable to provide a sealing ring or waterproof sealant at the connection point between the battery cover 801 and the side plate 500. In addition, it is conceivable to provide a locking mechanism or locking part on the battery cover 801, which would allow the user to securely fasten the battery cover 801.

[0105] Referring to Figures 1 to 3, a locking portion 802 is provided on the top of the battery cover 801, and a locking hole 803 is provided on the side plate 500. The locking portion 802 is an elastic locking portion, and when in use, the locking portion 802 is attached inside the locking hole 803, and the top of the locking portion 802 engages with the edge of the locking hole 803. When it is necessary to remove the battery cover 801, the worker presses the locking portion 802 along the vertical direction, causing the locking portion 802 to elastically deform, thereby releasing the engagement between the top of the locking portion 802 and the edge of the locking hole 803, and making it possible to remove the battery cover 801.

[0106] Furthermore, an insertion block is provided at the bottom of the battery cover 801, and an insertion hole 804 into which the insertion block can be inserted is provided at a corresponding position on the side plate 500. The bottom of the battery cover 801 is fixed by inserting the insertion block and the insertion hole 804 along the vertical direction.

[0107] Furthermore, referring to Figures 2 and 7, the battery cover 801 further includes a connecting bar 805. A first mounting hole is provided at the bottom of the battery cover 801, and a second mounting hole 806 is provided in the side plate 500. One end of the connecting bar 805 is locked and connected to the first mounting hole, and the other end is locked and connected to the second mounting hole 806.

[0108] Specifically, the connecting bar 805 is made of an elastic material, including but not limited to silicone and rubber.

[0109] When in use, the operator connects the connecting bar 805 to the battery cover 801 and the side plate 500, respectively. When attaching the battery cover 801, the insertion block is inserted into the insertion hole 804 and the locking part 802 is engaged with the locking hole 803, thereby fixing the battery cover 801 and the side plate 500. If it is necessary to remove the battery pack or storage compartment 400, the top of the battery cover 801 is detached from the side plate 500 by pressing the locking part 802. In this case, due to the action of the connecting bar 805, the bottom of the battery cover 801 does not detach from the side plate 500, and the battery cover 801 remains connected to the side plate 500. After the work is completed, the battery cover 801 can be reconnected to the side plate 500.

[0110] This configuration ensures that the battery cover 801 is securely attached to the side plate 500, making it less likely to fall off or get lost. This ensures the mounting stability and safety of the battery pack or storage compartment 400.

[0111] In some embodiments, referring to Figures 6, 8, and 9, a handle 900 for gripping and lifting the refrigerator is formed on the top of the side plate 500. The handle 900 is provided on the side plate 500 of the refrigerator housing 50, and a handle hole 901 for gripping is formed surrounding the handle 900 and the side plate 500 of the refrigerator housing 50. The top cover 501 of the refrigerator housing 50 is provided so as to cover at least above the handle 900, thereby shielding the handle hole 901 from the top of the refrigerator housing 50.

[0112] The top cover 501 may be configured to cover only the area above the handle 900, or it may be integrated with another cover plate that covers the area above the refrigerated region inside the refrigerator housing 50. In either case, it is sufficient that the cover plate allows the refrigerated region to be opened and closed.

[0113] The inner recess 505 is provided adjacent to the handle 900 and located below the handle hole 901. The bottom wall surface of the side panel 500 of the refrigerator housing 50, located below the inner recess 505, is flush with the outer surface of the handle 900, or the vertical distance between the bottom wall surface and the outer surface of the handle 900 is 5 cm or less. The handle 900 and the inner recess 505 work together to shield the handle hole 901 from the side of the refrigerator housing 50.

[0114] In the above, when it is stated that the bottom wall surface located below the inner recess 505 in the side panel 500 of the refrigerator casing 50 and the outer surface of the handle 900 are flush, it means that the surface of the handle 900 located on the outside of the refrigerator casing 50 and the surface on which the bottom wall surface located below the inner recess 505 is located are arranged on the same plane. When it is stated that the vertical distance between the bottom wall surface located below the inner recess 505 in the side panel 500 of the refrigerator casing 50 and the outer surface of the handle 900 is 5 cm or less, it means that the vertical distance between the plane on which the surface of the handle 900 located on the outside of the refrigerator casing 50 is located and the plane on which the bottom wall surface located below the inner recess 505 is located is 5 cm or less. For example, the handle 900 may be recessed toward the inside of the refrigerator casing 50, and the amount of recession may be 5 cm or less, or the handle 900 may be provided protruding toward the outside of the refrigerator casing 50, and the amount of protrusion may be 5 cm or less.

[0115] Specifically, the handle hole 901 is formed roughly along the vertical direction. This allows the worker's hand to be inserted horizontally into the handle hole 901 from the bottom of the handle 900, enabling them to grip the handle 900 and easily move the portable refrigerator.

[0116] In the portable refrigerator provided in this invention, the handle 900 is provided on the side plate 500 of the refrigerator housing 50, and together with the side plate 500, it forms a handle hole 901. Furthermore, the handle hole 901 is completely shielded by the top cover 501 and the inner recess 505, creating a concealed structure in which the handle 900 is difficult to see from the front. As a result, the handle 900 is more compactly integrated into the portable refrigerator, reducing the space occupied by the handle 900 and improving the appearance of the refrigerator.

[0117] In some embodiments, the vertical distance from the bottom of the handle 900 to the upper side of the battery pack is in the range of 25 mm to 45 mm. And / or, the vertical distance from the bottom of the handle 900 to the upper side of the storage compartment 400 is in the range of 25 mm to 45 mm.

[0118] Specifically, when the handle 900 is designed at an angle, the distance from the bottom of the handle 900 to the top surface of the battery pack and the distance from the bottom of the handle 900 to the top surface of the storage compartment 400 are different. On the other hand, when the handle 900 is designed horizontally, the distance from the bottom of the handle 900 to the top surface of the battery pack and the distance from the bottom of the handle 900 to the top surface of the storage compartment 400 are the same. The operator can change the distance from the bottom of the handle 900 to the top surface of the battery pack or the top surface of the storage compartment 400 as required by the structure, thereby achieving a configuration that is easier for the user to grip.

[0119] When the battery cover 801 is connected to the inner recess 505, the battery cover 801 is aligned with the side of the handle 900 that is away from the refrigerator casing 50.

[0120] Furthermore, referring to Figure 1, a rotating device 5011 is provided on the edge of the top cover 501. The rotating device 5011 is rotatably connected to the edge of the top cover 501. When in use, the operator can open and close the refrigerated area by operating the rotating device 5011.
