[0030] Figures 1-8 show portable devices provided in embodiments of the present invention.

[0031] As shown in Figures 1, 3, and 6, embodiments of the present invention provide a wheel assembly for a portable device. The wheel assembly includes a first movable wheel 200 and a second movable wheel 300. The first movable wheel 200 includes a first hub 201, a connector 202, and a first tire 203. The first hub 201 is provided with at least one first mounting hole along the axial direction. The second movable wheel 300 includes a second hub 301 and a second tire 307. The second tire 307 is fitted onto the outside of the second hub 301. The second hub 301 is provided with at least one second mounting hole along the axial direction. The first and second mounting holes are provided in a one-to-one correspondence. The connector 202 removably connects the first hub 201 and the second hub 301 through the first and second mounting holes. The diameter of the first tire 203 is greater than the diameter of the second tire 307. The tread of the first tire 203 is larger than the tread of the second tire 307. When the first hub 201 is connected to the second hub 301, the first tire 203 makes contact with the ground. When the first hub 201 is removed from the second hub 301, the second tire 307 makes contact with the ground.

[0032] Specifically, if the ground conditions are not complex, it is sufficient for the second moving wheel 300, which has a relatively small tread and a relatively small diameter, to be in operation. If the road conditions are poor and the ground conditions are complex, the first moving wheel 200 and the second moving wheel 300 are assembled together, and the first moving wheel 200, which has a relatively large diameter and a relatively wide tread, acts directly on the ground. The first moving wheel 200 is in operation and moves the device to which the wheel assembly is attached instead of the second moving wheel 300, in which case the second moving wheel 300 is lifted off the ground (not in contact with the ground).

[0033] Specifically, the connector 202 enables a detachable connection between the first hub 201 and the second hub 301.

[0034] Specifically, the second moving wheel 300 is an integral part of the portable device 100. Indoors or on flat surfaces, the second hub 301 and the second tire 307 can be used. When a tire with a wide contact surface is required on a complex outdoor surface, a first moving wheel 200 can be added to the second moving wheel 300, and the first hub 201 and the first tire 203 can be used.

[0035] Specifically, the first movable wheel 200 is attached to the second movable wheel 300. The first movable wheel 200 can be attached independently without removing the second movable wheel 300 during use, thereby improving the efficiency of attaching and detaching the first movable wheel 200.

[0036] The fixing screw 302 located in the middle of the second hub 301 is connected to the connecting rod between the two second moving wheels 300 of the portable device 100. Preferably, there are three first and second mounting holes, the second mounting holes are uniformly distributed around the fixing screw 302, and the positions of the first mounting holes correspond to the positions of the second mounting holes. Specifically, the three first mounting holes are arranged to form an equilateral triangle, the center of which coincides with the axis of the first hub, and the depth direction of the first mounting holes is aligned with the axial direction of the first hub. The three second mounting holes are connected to form another equilateral triangle, the center of which coincides with the axis of the second hub, and the depth direction of the second mounting holes is aligned with the axial direction of the second hub.

[0037] In the wheel assembly for the portable device provided in the present invention, when the portable device 100 needs to be used on a special road surface, the first moving wheel 200 is attached to the outside of the second moving wheel 300 by connecting the first hub 201 and the second hub 301 with a connector 202. Because the diameter of the first tire 203 is larger than the diameter of the second tire 307, the first moving wheel 200 can move the portable device 100 in place of the second moving wheel 300. Because the tread of the first tire 203 is larger than the tread of the second tire 307, the first moving wheel 200 can be applied to a variety of special road surfaces and facilitates movement outdoors. Furthermore, since the first moving wheel 200 and the second moving wheel 300 are detachably connected by the connector 202, storage is easy and the space occupied by the portable device 100 can be reduced.

[0038] The connector 202 includes a fall-prevention screw. The fall-prevention screw includes a threaded portion and a non-threaded shaft portion. The hole wall of the first mounting hole includes a threaded structure. The hole wall of the second mounting hole includes an insert nut 303. The threaded portion is screwed into the threaded structure and the insert nut. The handle 208 is attached to the non-threaded shaft portion.

[0039] Specifically, the first mounting hole is a through hole, and the anti-loosening screw is screwed into the threaded structure to prevent it from falling out, thus avoiding loss and facilitating the installation of the first hub 201.

[0040] Specifically, in order to reduce the weight of the second moving wheel 300, the inside of the second hub 301 is partially hollowed out, and the second mounting hole is designed as a hollow cylinder. The insert nut 303 is placed inside the second mounting hole. The insert nut 303 is integrally molded with the second hub 301. This enhances the shear resistance of the second moving wheel 300 and improves its structural stability.

[0041] During use, the operator aligns the first hub 201 and the second hub 301, inserts the anti-loosening screw into the insert nut 303, and rotates the anti-loosening screw to screw it into the insert nut 303 in the first and second mounting holes, thereby firmly connecting the first hub 201 and the second hub 301.

[0042] The placement of the anti-loosening screws prevents the connector 202 from loosening or falling off during use, simplifying installation and removal and improving operational efficiency.

[0043] Furthermore, depending on the usage conditions, the operator can install anti-loosening mechanisms such as spring washers or locking plates, which can more reliably prevent the connector 202 from loosening due to vibration.

[0044] The anti-loosening screw includes a threaded portion and a non-threaded shaft portion. The threaded portion is screwed into the insert nut 303 and the screw structure, and the handle 208 is connected to the non-threaded shaft portion.

[0045] Specifically, the fastening function is achieved by screwing the threaded portion with the screw structure and the insert nut 303.

[0046] During use, when attaching the first movable wheel 200, the threadless shaft portion can move up and down along the screw structure, thereby allowing the first movable wheel 200 to be easily attached to the second movable wheel 300. After ensuring that the first mounting hole and the second mounting hole are properly aligned, the operator can rotate the handle 208 to tighten the anti-loosening screw, thereby firmly connecting the first hub 201 and the second hub 301.

[0047] By providing the handle 208, the operator can more easily rotate the connector 202. In addition, by providing both a threadless shaft portion and a threaded portion, alignment and connection of the first mounting hole and the second mounting hole become easier, and the anti-loosening screw becomes more stable during use and less likely to loosen.

[0048] Furthermore, since the first movable wheel 200 is used on various complex outdoor surfaces in place of the second movable wheel 300, the material of the first tire 203 of the first movable wheel 200 is required to have higher wear resistance and tear resistance. Preferably, the first hub 201 is a plastic hub and the first tire 203 is made of rubber. When moving the portable device 100, the outer tread of the first movable wheel 200 is relatively flexible and has a large contact area, so it exhibits a cushioning effect, improves movement efficiency, and can be applied to various special surfaces.

[0049] In some embodiments, the first wheel 200 is a pneumatic tire. The first tire 203 includes an inner tire and an outer tire. The inner tire is connected to the first hub 201, and the outer tire is fitted over the inner tire. The first wheel 200 further includes an air valve 204. The air valve 204 is inserted into the first hub 201, with one end of the air valve 204 protruding from the outer surface of the first hub 201, and the other end of the air valve 204 communicating with the inner tire. Alternatively, the first wheel 200 is a one-piece molded foam wheel.

[0050] Specifically, the first tire 203 has a combined structure of an inner tire and an outer tire, and the air valve 204 is used to inflate the inner tire with air.

[0051] Specifically, the first hub 201 is provided with a hole for attaching an air valve 204. When the air valve 204 is inserted into the hole, it communicates with the inner tire from the side of the first hub 201. The operator then fits the outer tire onto the inner tire and the first hub 201, presses and aligns the outer and inner tires, and then connects the connector 202 to the first hub 201.

[0052] Before use, the operator first checks the air pressure of the first tire 203. If the air pressure is low, they pressurize it using an air pump through the air valve 204 before installing the first movable wheel 200. This configuration provides the first movable wheel 200 with a more stable tire structure, improving the durability and load-bearing capacity of the first tire 203. Furthermore, the design of the air valve 204 allows the user to easily adjust the air pressure of the first tire 203, adapting it to various road conditions and facilitating the outdoor movement of the wheel.

[0053] Furthermore, the first tire 203 may be a tubeless tire, that is, a fully air-filled tire. In this case, the stability and durability of the tire can be improved by reinforcing the tire wall and enhancing its sealing properties.

[0054] As shown in Figure 4, in another embodiment, the hardness of the first moving wheel 200 is lower than that of the second moving wheel 300. Preferably, the first moving wheel 200 is a polyurethane foam wheel 400, that is, the material of the first moving wheel 200 is a polyurethane foam material.

[0055] Specifically, polyurethane foam material has excellent elasticity and wear resistance, and can provide stable support and cushioning effect. In addition, since the polyurethane foam wheel 400 does not require air pressure checks or pressurization work, the air valve 204 can be omitted, and the structure of the first tire 203 can be simplified.

[0056] There is no need to check the air pressure during use; the operator simply needs to attach the connector 202 of the polyurethane foam wheel 400 to the second mounting hole. By using polyurethane foam material, the tire is lighter and more durable, adaptable to various complex road surfaces, and installation is also easier.

[0057] To optimize the above-mentioned technical proposal, the production process can be simplified and the number of parts reduced, thereby lowering production costs, by integrally molding the first hub 201 and the first tire 203. This configuration also contributes to improving the overall performance and structural strength of the product.

[0058] Furthermore, in order to improve the mounting efficiency of the first movable wheel 200, a guide member may be provided to guide the mounting of the first movable wheel 200. The specific structure is as follows.

[0059] As shown in Figure 5, in order to optimize the above-described technical proposal, at least one first insertion portion 205 is provided on the side of the first hub 201 closest to the second hub 301, and at least one second insertion portion 304 is provided on the side of the second hub 301 closest to the first hub 201, and the first insertion portion 205 and the second insertion portion 304 are connected by insertion.

[0060] Specifically, in order to reduce the weight of the second moving wheel 300, the inside of the second hub 301 is made hollow, and segmented ribs 306 are provided inside. The segmented ribs 306 support the second moving wheel 300 and also serve to divide the inside of the second hub 301 into multiple cavities. Each of these cavities can be used as a second insertion part 304.

[0061] When in use, the operator brings the first movable wheel 200 close to the second movable wheel 300, aligns the first insertion part 205 with the second insertion part 304, and aligns the first mounting hole with the second mounting hole. Subsequently, the connector 202 is pushed in until it engages with the second mounting hole, thereby inserting the first insertion part 205 into the second insertion part 304 and completing the installation of the first movable wheel 200 and the second movable wheel 300.

[0062] By providing the first insertion part 205 and the second insertion part 304, a simpler connection method is provided to the first movable wheel 200, improving the efficiency of installation and removal work. Furthermore, the configuration of the first insertion part 205 and the second insertion part 304 makes the connection between the first movable wheel 200 and the second movable wheel 300 even stronger, reducing the problem of loosening or detachment that may occur during use, making it more suitable for outdoor use.

[0063] Furthermore, the first insertion part 205 and the second insertion part 304 may be attached by magnetic attraction. The first insertion part 205 and the second insertion part 304 can be quickly connected and stably fixed by the action of magnetism.

[0064] As shown in Figure 8, in order to optimize the above-described technical proposal, a plurality of grooves 206 are formed on the side of the first hub 201 closer to the second hub 301, and at least one first insertion portion 205 is positioned inside the same groove 206, with the first insertion portion 205 protruding from the bottom of the groove 206. On the other hand, a plurality of segmented ribs 306 extending along the axial direction of the second hub 301 are provided on the side of the second hub 301 closer to the first hub 201, and the second insertion portion 304 is configured as a cavity surrounded by the segmented ribs 306.

[0065] Specifically, in order to reduce the weight of the first moving wheel 200, a plurality of grooves 206 are formed on the first side of the first hub 201, and the first insertion portion 205 has a hollow structure. Preferably, there are three first insertion portions 205 and three second insertion portions 304, which are evenly arranged around the fixing screw 302.

[0066] Specifically, one or more first insertion portions 205 may be arranged inside the groove 206, and the position and number of the first insertion portions 205 can be flexibly set according to the usage requirements.

[0067] Specifically, when the second mounting hole is designed as a hollow cylinder, the second mounting hole can be positioned on the side wall of the groove 206, and the second mounting hole and the first insertion portion 205 are positioned so as not to interfere with each other. In addition, to ensure the structural strength of the second mounting hole and the groove 206, reinforcing ribs may be provided between the groove wall of the groove 206 in which the second mounting hole is provided and the groove wall of the adjacent groove 206.

[0068] Specifically, the first insertion portion 205 and the groove 206 are designed as a single unit.

[0069] Specifically, the position of the groove 206 corresponds to the position of the cavity, which enhances the engagement effect of the first moving wheel 200 and the second moving wheel 300.

[0070] This configuration allows the connection between the first insertion part 205 and the second insertion part 304 to be more concealed, improving the overall appearance of the first moving wheel 200. Furthermore, additional support and stability are provided, increasing the connection strength between the first hub 201 and the second hub 301.

[0071] Referring to Figure 7, in order to optimize the above-mentioned technical proposal, the wheel assembly further comprises an end cover 500, the end cover 500 of which is provided with an engaging portion 501. A first connecting portion 207 is formed on the side of the first hub 201 opposite to the second hub 301, and a second connecting portion 305 is provided on the side of the second hub 301 closer to the first hub 201. When mounting the first movable wheel 200 and the second movable wheel 300, the engaging portion 501 is connected to the first connecting portion 207, and when removing the first movable wheel 200 and the second movable wheel 300, the engaging portion 501 is connected to the second connecting portion 305.

[0072] The end cover 500 is a shared end cover 500 for both the first and second moving wheels 200 and 300. In the initial state, the end cover 500 is connected to the second hub 301 of the second moving wheel 300, that is, the engaging portion 501 is connected to the second connecting portion 305. If it is necessary to add a first moving wheel 200, the operator pries open and removes the end cover 500 from the second moving wheel 300, attaches the first moving wheel 200 to the second moving wheel 300, and then connects the end cover 500 to the first hub 201, that is, the engaging portion 501 is switched to be connected to the first connecting portion 207.

[0073] The engaging portion 501 is an insertion rod, which is provided along a direction perpendicular to the end cover 500. The first end of the insertion rod is connected to the end cover 500, and the second end extends toward the first hub 201, and the second end has a bent shape and is used to engage with the first connecting portion 207 or the second connecting portion 305.

[0074] Specifically, it is preferable that the number of insertion rods be three. It is preferable that the number of grooves 206 be six, and that the number of cavities be six. It is preferable that the number of first connecting parts 207 be three, and that the number of second connecting parts 305 be three.

[0075] Specifically, it is preferable that the first connecting portion 207 and the first insertion portion 205 be spaced apart between the multiple grooves 206. Similarly, it is preferable that the second connecting portion 305 and the second insertion portion 304 be spaced apart between the multiple cavities. This equalizes the forces acting on the first hub 201 and the second hub 301, thereby ensuring their structural strength.

[0076] Specifically, support ribs are provided between the insertion rod and the end cap 500. The support ribs are used to ensure stability when the insertion rod is inserted into the first connection part 207 or the second connection part 305.

[0077] Specifically, the structure of the first connecting portion 207 and the second connecting portion 305 is identical. The second connecting portion 305 includes a guide plate for inserting and guiding the insertion rod, and an engagement plate for engaging the second end (bent portion) of the insertion rod.

[0078] The design of the end cover 500 makes the structure of the first moving wheel 200 more complete and improves its appearance. In addition, the end cover 500 provides additional support and stability. The engagement of the engaging portion 501 with the first connecting portion 207 or the second connecting portion 305 ensures that the end cover 500 is firmly connected to the first hub 201 and the second hub 301.

[0079] As described above, the present invention enables the portable device 100 to move flexibly under different road surface conditions and obtain stable support by providing a detachable first movable wheel 200. Furthermore, it can reduce the space occupied by the wheel indoors or in a vehicle, improving the practicality of the product and the user experience.

[0080] Embodiments of the present invention further provide a portable device 100. The portable device 100 includes a device body and a wheel assembly of any one of the portable devices described above. The first movable wheel 200 and the second movable wheel 300 are detachably connected, and the wheel assembly is connected to the device body to move the device body of the portable device 100.

[0081] The portable device 100 may be a mobile energy storage device, or it may be an outdoor mobile device such as an outdoor refrigerator.

[0082] As shown in Figure 2, in order to optimize the above-described technical proposal, the portable device 100 includes two sets of wheel assemblies. The second moving wheels 300 of the two sets of wheel assemblies are positioned opposite each other on one side of the device body of the portable device. The portable device body is provided with two opposing connecting holes 601, the two connecting holes 601 being located on the side of the device body of the portable device 100 away from the wheel assemblies. The wheel assemblies further include a bracket 600, the ends of which are engagedly connected or rotatably connected to the two connecting holes 601, respectively. The first moving wheel 200 of the wheel assembly is connected to the second moving wheel 300. When the bracket 600 is connected to the connecting holes 601, the portable device 100 is positioned horizontally.

[0083] Specifically, if the portable device 100 includes two sets of wheel assemblies, the two sets of second moving wheels 300 may or may not be connected by a single axis of rotation.

[0084] Specifically, the bracket has a U-shaped design.

[0085] Specifically, both ends of the bracket 600 and the two connecting holes 601 are connected by engagement using structures such as locking grooves and engaging claws. Alternatively, both ends of the bracket 600 and the two connecting holes 601 may be rotatably connected by structures such as a rotating shaft. In addition to connection methods by engagement and rotation, the connection method between the bracket 600 and the connecting holes 601 of the portable device 100 may be telescopic or hinged, and the specific structure can be appropriately set according to the needs of use, and a detailed explanation is omitted in this specification.

[0086] Specifically, after the bracket 600 is connected to the connecting hole 601, the distance from the bottom of the bracket 600 to the top of the portable device 100 is equal to the distance from the bottom of the first moving wheel 200 to the top of the portable device 100. This allows the portable device 100 to maintain a horizontal position when installed.

[0087] Specifically, the connecting hole 601 of the portable device 100 is designed to accommodate a handle 208. Both ends of the bracket 600 are locked into the interior of two detachable handles 208, forming a stable connection.

[0088] When in use, after the portable device 100 reaches a predetermined position, the operator can quickly attach the bracket 600 by first locking one end of the bracket 600 into one of the connecting holes 601, and then pressing and deforming the other end of the bracket 600 to lock it into the other connecting hole 601.

[0089] The bracket 600 provides additional support and stability to the portable device 100, ensuring safety and stability during installation. Furthermore, the U-shaped structure of the bracket 600 allows for easy engagement with the connecting hole 601 of the portable device 100, improving the convenience of installation.

[0090] To optimize the above-described technical proposal, the wheel assembly further includes a support frame. The support frame is rectangular in shape, and its top is connected to the bottom of the portable device 100.

[0091] Specifically, the support frame supports the portable device 100 and is used to stabilize the portable device 100 when it is installed. The support frame can be used selectively with the bracket 600 mentioned above. The support frame may be designed as a hollow rectangular column, and since only one end surface needs to be connected to the bottom of the portable device 100, the overall weight of the portable device 100 can be reduced.

[0092] In some embodiments, the support frame is fixedly connected to the portable device 100, thereby improving the stability of the connection between the support frame and the portable device 100.

[0093] The support frame is rotatably connected to the portable device 100. When the support frame is retracted, it is housed in the bottom of the portable device 100 (a storage space is formed in the bottom of the portable device 100), and when the support frame is deployed, it is used to support the portable device 100.

[0094] By providing a support frame, the portable device 100 is given additional support and stability, ensuring safety and stability when the portable device 100 is installed.

[0095] For the specific structure of the wheel assembly of this portable device 100, please refer to the embodiments described above. Since this portable device 100 employs all the technical proposals in each of the embodiments described above, it possesses at least all the beneficial effects obtained from the embodiments described above. In order to avoid redundant explanations, detailed descriptions are omitted in this specification.

[0096] Figures 9-20 show portable devices provided in another embodiment of the present invention.

[0097] Referring to Figures 9 and 10, as shown in Figure 9, the outdoor refrigerator 10 provided in one embodiment of the present invention may be a portable, mobile outdoor refrigerator and can be used indoors and outdoors. The outdoor refrigerator 10 includes a main body 11 and a foldable storage basket 12. The main body 11 is provided with a freezer compartment 101, and the foldable storage basket 12 is fixed inside the freezer compartment 101. The foldable storage basket 12 is provided with an opening cavity 130, and items are stored inside the opening cavity 130. When it is necessary to remove items, the entire foldable storage basket 12 can be removed from the freezer compartment 101, thereby allowing the items to be removed from the opening cavity 130 of the foldable storage basket 12 outside the main body 11. This configuration eliminates interference with the main body 11, makes it possible to smoothly remove items, and improves the convenience of using the outdoor refrigerator 10.

[0098] Referring to Figures 11, 12, and 13, in some embodiments, the foldable storage basket 12 includes a side frame assembly 100 and a bottom frame 200. The bottom frame 200 is rotatably mounted on one end of the side frame assembly 100, and the bottom frame 200 and the side frame assembly 100 form an opening cavity 130. When the bottom frame 200 is placed on top of the side frame assembly 100, the side frame assembly 100 becomes foldable. In the process of folding the side frame assembly 100, the opening cavity 130 gradually shrinks and eventually disappears completely, at which point the side frame assembly 100 and the entire foldable storage basket 12 are in a fully folded state.

[0099] For the sake of explanation, the three directions in space will be referred to as the first direction, the second direction, and the third direction. The first and second directions are positioned at an angle, and the third direction is perpendicular to both the first and second directions. For example, if the first and second directions are orthogonal to each other, the first, second, and third directions can be understood as the extension directions of the three coordinate axes in a spatial orthogonal coordinate system, in which case the first direction is the X-axis direction, the second direction is the Y-axis direction, and the third direction is the Z-axis direction.

[0100] As shown in Figures 11, 12, and 13, in some embodiments, the side frame assembly 100 includes at least two side frames. When the two side frames are spaced apart from each other, the opening cavity 130 expands, thereby creating storage space in the opening cavity 130. When the two side frames are close together, the opening cavity 130 contracts, and the foldable storage basket 12 is folded. For example, the side frame assembly 100 includes a first side frame 110 and a second side frame 120. There are two first side frames 110, and the two first side frames 110 are spaced apart along a first direction. Similarly, there are also two second side frames 120, and the two second side frames 120 are spaced apart along a second direction. Thus, the side frame assembly 100 includes a total of four side frames. Both ends of the second side frame 120 in the first direction are rotatably connected to the two first side frames 110 about a rotation axis extending along the third direction. Specifically, both ends of one second side frame 120 in the first direction are rotatably connected to one end of each of the two first side frames 110 in the second direction, and both ends of the other second side frame 120 in the first direction are rotatably connected to the other end of each of the two first side frames 110 in the second direction.

[0101] As shown in Figures 11, 12, and 13, the bottom frame 200 is provided at one end of the side frame assembly 100 in a third direction, and the bottom frame 200 and the side frame assembly 100 form an opening cavity 130. When the first and second directions are orthogonal to each other, the entire foldable storage basket 12 has a roughly rectangular parallelepiped structure. The bottom frame 200 is rotatably connected to one first side frame 110 about a pivot axis extending along the second direction, and the bottom frame 200 is further supported in the third direction by a second side frame 120 and / or another first side frame 110. The support provided by the second side frame 120 and / or the first side frame 110 allows the bottom frame 200 to form an opening cavity 130 together with the side frame assembly 100, and the bottom frame 200 can support articles stored in the opening cavity 130. In other embodiments, the foldable storage basket 12 may be a regular triangular prism structure or another regular polygonal prism structure, as long as the foldable storage basket 12 is foldable.

[0102] As shown in Figures 12, 13, 14, and 15, during the storage, packaging, and transport of the foldable storage basket 12, the bottom frame 200 is first rotated around a pivot axis extending in the second direction, and the bottom frame 200 is placed on top of one of the first side frames 110. Then, the first side frame 110 on which the bottom frame 200 is placed is fixed, and the two second side frames 120 are simultaneously rotated clockwise relative to the first side frame 110 on which the bottom frame 200 is placed, so that one second side frame 120 is placed on top of the first side frame 110 on which the bottom frame 200 is placed, and the other second side frame 120 extends in the same direction as the first side frame 110 on which the bottom frame 200 is placed, so that they do not overlap each other. This state means that the plane on which the other second side frame 120 is located is flush with the plane on which the first side frame 110 on which the bottom frame 200 is placed. Another first side frame 110 is placed on top of a second side frame 120, which is coplane with the first side frame 110 on which the bottom frame 200 is placed. Thus, the foldable storage basket 12 can be understood as being in a fully folded state. Obviously, when the foldable storage basket 12 is used to store items, the foldable storage basket 12 is in a fully unfolded state. Also, when the first side frame 110 and the second side frame 120 extend in the same direction, the first side frame 110 and the second side frame 120 overlap each other. In this case, the planes on which the first side frame 110 and the second side frame 120 are located overlap each other. On the other hand, when the first side frame 110 and the second side frame 120 do not overlap, the planes on which they are located are coplane. Clearly, when the foldable storage basket 12 is folded and stored, the bottom frame 200 moves closer to the side frame assembly 100, and when the foldable storage basket 12 is unfolded and used as storage space, the bottom frame 200 moves away from the side frame assembly 100. During the folding process, the two first side frames 110 move closer to each other, and the two second side frames 120 also move closer to each other. During the unfolding process, the two first side frames 110 move away from each other, and the two second side frames 120 also move away from each other.

[0103] As can be understood, if a foldable storage basket 12 needs to be placed in the main body 11 of the outdoor refrigerator 10, the foldable storage basket 12 will be separated from the main body 11 and transported, packaged, and stored separately. During the process of transporting, packaging, and storing the foldable storage basket 12 separately, the foldable storage basket 12 can be fully folded, thereby significantly reducing the overall volume of the foldable storage basket 12 and improving the convenience of transporting, packaging, and storing the foldable storage basket 12. In addition, the costs required for transporting, packaging, and storing the foldable storage basket 12 can be reduced.

[0104] In some embodiments, when the foldable storage basket 12 is fully folded, the bottom frame 200 is held inside the side frame assembly 100. This configuration allows the side frame assembly 100 to provide good positioning relative to the bottom frame 200 and prevents the bottom frame 200 from rotating relative to the first side frame 110. This improves the ease of use of the foldable storage basket 12 during transport, packaging, and storage. In other embodiments, when the foldable storage basket 12 is fully folded, the bottom frame 200 may be located outside the side frame assembly 100.

[0105] As shown in Figures 11 and 12, in some embodiments, the foldable storage basket 12 may further include a support member 300. The support member 300 is provided projecting from at least one of the bottom frame 200, the first side frame 110, and the second side frame 120, and the support member 300 abuts against the bottom frame 200 or the first side frame 110 in a third direction. For example, the connecting end of the bottom frame 200 is connected to one first side frame 110, and the support member 300 is provided projecting along the first direction at a free end located away from the connecting end on the bottom frame 200. This connecting end and free end are the opposite ends of the bottom frame 200 in the first direction. The support member 300 abuts against another first side frame 110 in a third direction, thereby allowing the first side frame 110 to support the bottom frame 200 well via the support member 300. As can be understood, in the process of the bottom frame 200 rotating relative to the first side frame 110, the user applies force to the support member 300 on the bottom frame 200, thereby allowing the support member 300 to easily rotate the bottom frame 200 relative to the first side frame 110, improving the usability of the foldable storage basket 12. Of course, the support member 300 may be provided protruding from the first side frame 110 near the free end of the bottom frame 200 along the first direction. By having this support member 300 abut the bottom frame 200 in the third direction, the first side frame 110 can support the bottom frame 200 via the support member 300.

[0106] As shown in Figures 11 and 12, in some embodiments, in order to increase the support capacity of the bottom frame 200 and improve the stability and reliability of the foldable storage basket 12, each of the two second side frames 120 is provided with a support member 300 projecting along a second direction. The bottom frame 200 abuts the support member 300 in a third direction, and in this configuration, the two second side frames 120 can each support the bottom frame 200 and bear the load via different support members 300. In other embodiments, the support member 300 may project from any of the bottom frame 200, the first side frame 110, and the second side frame 120.

[0107] As shown in Figures 11 and 12, in some embodiments, the side frame assembly 100 has a free end that is set away from the bottom frame 200, and this free end is one end of the side frame assembly 100 in a third direction. Near the free end of the first side frame 110 and / or the second side frame 120, a recessed space 140 is formed toward the opening cavity 130. For example, the recessed space 140 may be provided only in the first side frame 110, or only in the second side frame 120, or in both the first side frame 110 and the second side frame 120. By providing the recessed space 140, when the foldable storage basket 12 is installed in the freezer compartment 101 of the main body 11, the position where the recessed space 140 is provided in the first side frame 110 or the second side frame 120 does not come into contact with the inner wall surface of the freezer compartment 101, and a certain distance is maintained. In this way, the user's hands can enter the retraction space 140 and apply an upward force to the foldable storage basket 12, thereby making it possible to remove the entire foldable storage basket 12 from the freezer compartment 101. This greatly improves the ease of use of the foldable storage basket 12.

[0108] As shown in Figures 11 and 12, in some embodiments, the first side frame 110, the second side frame 120, and the bottom frame 200 all include a plurality of support rods 150, and a mesh-like structure is formed by the plurality of support rods 150. Therefore, the first side frame 110, the second side frame 120, and the bottom frame 200 all have a mesh-like structure. For example, the first side frame 110 is constructed surrounded by a plurality of support rods 150 extending along the second and third directions, and the mesh holes of the mesh-like structure of the first side frame 110 are generally rectangular in shape. The second side frame 120 is constructed surrounded by a plurality of support rods 150 extending generally along the first and third directions, and the mesh holes of the mesh-like structure of the second side frame 120 are generally rectangular in shape. The bottom frame 200 is surrounded by a plurality of support rods 150 that extend generally along the first and second directions, and the mesh holes of the mesh-like structure of the bottom frame 200 are generally rectangular in shape. In other embodiments, the mesh holes of the first side frame 110, the second side frame 120 and the bottom frame 200 may be substantially rhombic or regular polygonal, etc.

[0109] As shown in Figures 11 and 12, in some embodiments, the second side frame 120 is provided with a rotation hole, which is referred to as the first rotation hole 161. A support rod 150 extending along the third direction in the first side frame 110 is rotatably engaged with the first rotation hole 161, thereby realizing a rotational connection between the first side frame 110 and the second side frame 120. In other words, the first side frame 110 rotates through the first rotation hole 161 and rotates in cooperation with the second side frame 120. Of course, the first rotation hole 161 may also be provided in the first side frame 110, in which case a rotational connection between the first side frame 110 and the second side frame 120 can be similarly realized by a support rod 150 extending along the third direction in the second side frame 122 rotatably engaging with the first rotation hole 161.

[0110] As shown in Figures 11 and 12, in some embodiments, the first side frame 110 is provided with a rotation hole, which is referred to as the second rotation hole 162. A support rod 150 extending along the second direction in the bottom frame 200 engages with the second rotation hole 162, thereby realizing a rotational connection between the bottom frame 200 and the first side frame 110. In other words, the bottom frame 200 rotates through the second rotation hole 162 and rotates in cooperation with the first side frame 110. Of course, the second rotation hole 162 may also be provided in the bottom frame 200. In this case, the support rod 150 extending along the second direction in the first side frame 110 engages with the second rotation hole 162, thereby similarly realizing a rotational connection between the bottom frame 200 and the first side frame 110.

[0111] As shown in Figures 17, 18, 19, and 20, in some embodiments, two second side frames 120 each include two rotating parts 121, the lengths of the two rotating parts 121 in the first direction being equal. One end of the two rotating parts 121 is rotatably connected by a pivot axis extending along a third direction, and the other end of the two rotating parts 121 is rotatably connected to different first side frames 110 by pivot axes extending along the third direction. When it is necessary to fold the foldable storage basket 12, the bottom frame 200 is first rotated to overlap one of the first side frames 110 with the other. Next, the first side frame 110 on which the bottom frame 200 is stacked is fixed, and the two rotating parts 121 directly connected to the first side frame 110 on which the bottom frame 200 is stacked are rotated so that the two rotating parts 121 are stacked on top of each other with the first side frame 110 on which the bottom frame 200 is stacked. This state means that the second side frame 120 is recessed inward. Once the stacking of the two rotating parts 121 directly connected to the first side frame 110 on which the bottom frame 200 is stacked is complete, the two rotating parts 121 on the same second side frame 120 are also stacked on top of each other. Furthermore, another first side frame 110 is also stacked on top of the rotating parts 121. That is, the two rotating parts 121 on the same second side frame 120 overlap within the gap between the two first side frames 110. As a result, both rotating parts 121 on the same second side frame 120 are sandwiched between the two first side frames 110. This allows the foldable storage basket 12 to be fully folded, further reducing the volume of the foldable storage basket 12 when fully folded. As a result, the convenience of use during transport, packaging, and storage of the foldable storage basket 12 is further improved, and the costs required for transport, packaging, and storage are further reduced. Of course, during the folding process, a configuration in which the second side frame 120 protrudes outward can also be adopted. With the first side frames 110, on which the bottom frame 200 is stacked, fixed, the two rotating parts 121 provided on the same second side frame 120 overlap each other, and the two first side frames 110 also overlap each other. However, the two overlapping rotating parts 121 are located outside the two first side frames 110 and are not sandwiched between the two first side frames 110. Even with this configuration, it is possible to achieve a fully folded state for the foldable storage basket 12.In other words, the two rotating parts 121 provided on the same second side frame 120 are folded outwards into the gap between the two first side frames 110.

[0112] To ensure understanding, depending on the actual usage situation, a foldable storage basket 12 having two rotating parts 121 on the second side frame 120 can also adopt a folding method of a foldable storage basket 12 that does not have two rotating parts 121 on the second side frame 120.

[0113] As shown in Figures 9 and 10, in some embodiments, the main body 11 is further provided with a hanger 102. The hanger 102 is provided protruding from the inner wall surface of the freezer compartment 101 and is used to suspend the foldable storage basket 12 after it has been folded. For example, in a foldable storage basket 12 in which the second side frame 120 includes two rotating parts 121, if a folding method is adopted in which the second side frame 120 is recessed inward, the foldable storage basket 12 can be folded inside the freezer compartment 101 and the fully folded foldable storage basket 12 can be suspended from the hanger 102. Furthermore, if it is necessary to unfold the foldable storage basket 12 to store items, it is also possible to transform the foldable storage basket 12 from a fully folded state to a fully unfolded state inside the freezer compartment 101. Therefore, by suspending the fully folded foldable storage basket 12 from the hanger 102, it is possible to prevent the foldable storage basket 12 from colliding with the inner wall surface of the freezer compartment 101 and damaging the main body 11 during transport of the outdoor refrigerator 10.

[0114] In some embodiments, both the first side frame 110 and the second side frame 120 abut against the inner wall surface of the freezer compartment 101. This can be understood as the volume of the foldable storage basket 12 being approximately equal to the volume of the freezer compartment 101, roughly filling the entire freezer compartment 101. In this case, the length and width of the foldable storage basket 12 are equal to the length and width of the freezer compartment 101, and all items can be stored in the opening cavity 130 of the foldable storage basket 12. When the length and width of the foldable storage basket 12 are equal to the length and width of the freezer compartment 101, the distance between the two first side frames 110 is equal to the distance between two inner wall surfaces spaced apart along the first direction of the freezer compartment 101, and the distance between the two second side frames 120 is equal to the distance between two inner wall surfaces spaced apart along the second direction of the freezer compartment 101.

[0115] In some embodiments, if the length of the foldable storage basket 12 is not equal to the length of the freezer compartment 101, or if the width of the foldable storage basket 12 is not equal to the width of the freezer compartment 101, the spacing between the two first side frames 110 can be understood to be smaller than the distance between two inner wall surfaces spaced apart along the first direction of the freezer compartment 101, or the spacing between the two second side frames 120 can be understood to be smaller than the distance between two inner wall surfaces spaced apart along the second direction of the freezer compartment 101. When the foldable storage basket 12 is placed inside the freezer compartment 101, at least one of the two adjacent first side frames 110 and second side frames 120 is spaced apart from the inner wall surface of the freezer compartment 101. This situation means that the volume of the foldable storage basket 12 is smaller than the volume of the freezer compartment 101 and cannot fill the entire freezer compartment 101. The length or width of the foldable storage basket 12 may be approximately 50 mm smaller than the length or width of the freezer compartment 101. Therefore, items can be stored in the opening cavity 130 of the foldable storage basket 12, and items can also be stored in the space located outside the opening cavity 130 in the freezer compartment 101.

[0116] In some embodiments, the foldable storage basket 12 may also be equipped with an anti-slip structure, which is provided on the bottom frame 200. The anti-slip structure may be an uneven surface formed on the bottom frame 200, thereby increasing the surface roughness of the bottom frame 200. Of course, the anti-slip structure may also be a high-friction anti-slip layer attached to the bottom frame 200. By providing a protective structure (anti-slip structure), it is possible to prevent the foldable storage basket 12 from sliding around in the freezer compartment 101 after it has been unfolded.

[0117] Figures 21-32 show portable devices provided in another embodiment of the present invention.

[0118] As shown in Figures 21 and 24, the outdoor portable device provided in the embodiment of the present invention includes a device body and a hanging device 100. The hanging device 100 is connected to the outer wall of the device body and is provided with a hanging portion. The length of the hanging portion is provided along the horizontal direction and the hanging device 100 is used to store outdoor equipment on the outdoor portable device via the hanging portion. The hanging portion includes at least one of a locking groove 101 and a through hole 102.

[0119] Specifically, since the hook 100 is provided on the outer surface of the device, it needs to be lightweight and compact, and its thickness should be as thin as possible so as not to protrude excessively from the outer surface of the device while still meeting the requirements for carrying. Furthermore, the length of the hook 100 should be shorter than the length of the device body so that the hook 100 does not extend beyond the side of the device. Therefore, the hook 100 should be designed with reasonable dimensions to meet the product's usage requirements. The design of the hook 100 according to the present invention allows the tool body to be easily hung on the device, provides the function of the device carrying the tool body during transport, avoids additional carrying burden and improves the practicality of the device.

[0120] The outdoor portable device may be an outdoor mobile power supply, an outdoor mobile refrigerator, or an outdoor mobile air conditioner.

[0121] Specifically, preferably, the fastener 100 is provided on the side of the device's outer shell, which facilitates the fixing and attachment of the fastener 100.

[0122] The outdoor portable device provided in the present invention includes a device body and a hanging device. When in use, the hanging device 100 is attached to the outer surface of the device body, and the device body is connected to the hanging device 100 via a hanging portion. Since the hanging portion includes at least one of a locking groove and a through hole, the hanging device 100 can hold different articles, and can meet the diverse usage requirements of the user. As a result, the usage scenarios of the outdoor portable device are expanded.

[0123] In some embodiments, the hook 100 is fixedly connected to the device.

[0124] Specifically, the mounting bracket 100 is fixed to the side of the device by connection methods such as insertion, adhesive, or screw joining. In this invention, it is preferable to use a bolt connection between the mounting bracket 100 and the device, thereby ensuring connection stability. That is, the mounting bracket 100 is provided with screw holes aligned horizontally, and the outer surface of the outdoor portable device is provided with mounting holes that fit the screw holes.

[0125] Specifically, the fastener 100 can be securely fixed to the device using fasteners such as bolts.

[0126] In some embodiments, the inside of the fastener 100 is a solid structure, and the locking groove 101 is formed only in the Z direction. The fastener 100 is provided with a threaded hole that penetrates the fastener 100 horizontally, and a bolt passes through the threaded hole and mounting hole to connect the fastener 100 to the side of an outdoor portable device, thereby securing the fastener 100 to the device.

[0127] In another embodiment, the inside of the hook 100 is hollow, and the inside of the hook 100 is provided with multiple reinforcing ribs to increase its structural strength and studs for fixing the hook 100. Threaded holes are formed inside the studs. Bolts pass through these threaded holes and mounting holes to connect the hook 100 to the side of the device, thereby fixing the hook 100 in place. In this embodiment, the weight of the hook 100 is reduced, and the structural strength of the hook 100 is ensured by the placement of reinforcing ribs, making it possible to support and hang the main body of the tool.

[0128] Furthermore, it is preferable that the screw holes be uniformly distributed on the left, right, and central parts of the hook 100. Preferably, a total of six screw holes are arranged on the left, center, and right sides of the hook 100 to satisfy the fixing requirements of the hook 100.

[0129] The above configuration provides a stable connection method to the hook 100, ensuring the stability of the hook 100 during use. Furthermore, the design of the screw holes and mounting holes makes it easy and quick to attach and detach the hook 100, and facilitates the storage and assembly of the hook 100 and the device.

[0130] Specifically, the direction in which the through-hole 102 is formed is the same as the direction in which the locking groove 101 is formed.

[0131] The hook portion includes a plurality of locking grooves 101, which are spaced apart along the length of the hook portion. Alternatively, the hook portion includes a plurality of through holes 102, which are spaced apart along the length of the hook portion. Alternatively, the hook portion includes a plurality of locking grooves 101 and a plurality of through holes 102, which are spaced apart along the length of the hook portion.

[0132] Specifically, both the locking groove 101 and the through hole 102 are used to hang outdoor equipment. Depending on the shape and dimensions of the equipment, the user can choose to hang the equipment using the locking groove 101 and / or the through hole 102.

[0133] Specifically, the specifications of the locking groove 101 are designed based on the thickness and length of the hook 100. In this invention, it is preferable that the length of the locking groove 101 be 100 mm.

[0134] The hanging device 100 includes a front surface 103 facing outwards, a back surface 104 facing the device body, and a top surface, bottom surface, left side surface, and right side surface located on and sequentially connected to the front surface 103 and back surface 104. Of these top surface, bottom surface, left side surface, and right side surface, at least the bottom surface is formed to be recessed toward the top surface.

[0135] Specifically, preferably, the hook 100 has a rectangular structure enclosed by a front surface 103, a back surface 104, a top surface, a bottom surface, a left side surface, and a right side surface. The locking groove 101 and through hole 102 are provided on the top surface and the bottom surface, and the locking groove 101 and through hole 102 are formed to penetrate along the vertical direction. This facilitates the insertion of the insertion structure described later.

[0136] When in use, if the bottom surface is recessed inward toward the top surface, the first insertion part described below is inserted into the locking groove 101, and the bent-back portion 503 of the first insertion part comes into contact with the recessed bottom surface, thereby forming a tight lock.

[0137] Furthermore, in the above-described method of connecting the hook 100 to the device, the hook 100 protrudes from the outside of the device, which not only affects the appearance of the device but also makes the hook 100 and the device prone to snagging when the device is moved, potentially causing damage or breakage. Therefore, by further improving the method of connecting the hook 100 to the device and adjusting its structure, position, and storage method, it is possible to prevent the hook 100 from protruding from the outside of the device when it is stored.

[0138] A housing groove is provided on the outer wall of the device body. The length of the housing groove extends horizontally, the width of the housing groove extends vertically, and the depth of the housing groove extends from the horizontal toward the interior of the device body. The housing groove is for housing the hook 100.

[0139] In another embodiment, the hook 100 is rotatably connected to the device.

[0140] As shown in Figure 25, to optimize the above-mentioned technical proposal, a rotating assembly 200 is further included. The rotating assembly 200 includes a first hinge 207, a second hinge 208, and a first pivot axis. Here, the first hinge 207 includes a first connecting portion 201 and a first fixing portion 202, and the second hinge 208 includes a second connecting portion 203 and a second fixing portion 204. The first connecting portion 201 and the second connecting portion 203 are rotatably connected by the first pivot axis, the first fixing portion 202 is connected to the hook 100, and the second fixing portion 204 is connected to the groove wall of the housing groove. When the first fixing portion 202 and the second fixing portion 204 are bonded together, the hook 100 is housed inside the housing groove, and when the first fixing portion 202 and the second fixing portion 204 are separated from each other, the hook 100 is released from inside the housing groove.

[0141] The rotating assembly 200 includes a first hinge 207, a second hinge 208, and a first pivot axis, which together constitute a rotatable mechanism. When the first fixed part 202 and the second fixed part 204 are bonded together, the hook 100 is housed in a housing groove on the outer surface of the device, and when they are separated from each other, the hook 100 can be released from the housing groove.

[0142] Specifically, the first fixing portion 202 is connected to the hanger 100 by fasteners such as bolts, and the second fixing portion 204 is connected to the housing groove by fasteners such as bolts. In the present invention, it is preferable that the first fixing portion 202 includes two mounting holes for attaching fasteners, and the second fixing portion 204 includes two mounting holes for attaching fasteners.

[0143] Specifically, the sum of the lengths of the first connecting portion 201 and the second connecting portion 203 is equal to the length of the axis of rotation, and the first connecting portion 201 and the second connecting portion 203 are connected to the same axis of rotation and can rotate relative to each other.

[0144] Specifically, one or more rotary assemblies 200 can be placed on a single outdoor portable device, and in the present invention, it is preferable to place one rotary assembly 200 at each end of the outdoor portable device.

[0145] Specifically, when forming the receiving groove, it is necessary to consider the attachment of the fastener 100 and to secure the mounting space for the rotating assembly 200 in advance.

[0146] Specifically, in the present invention, the locking groove 101 is preferably provided along the z-direction of the hook 100, thereby maximizing the space and number of the locking groove 101 and facilitating the hooking of the tool body.

[0147] In the initial state, the first fixing part 202 is fixed to the hook 100, the second fixing part 204 is fixed to the housing groove, the hook 100 is housed inside the housing groove, and the first fixing part 202 and the second fixing part 204 are bonded to each other. When an operator reaches their hand into the housing groove and applies force to the hook 100, the action of the rotation axis causes the hook 100 to move out of the housing groove and detach from the inside of the housing groove, and the locking groove 101 is positioned vertically, thereby allowing the tool body to be hung. The rotating assembly 200 provides a flexible storage method, the hook 100 is housed inside the housing groove, and the outdoor portable device does not occupy extra space when not in use. In addition, the structure of the rotating assembly 200 makes it easy to deploy and store the hook 100, making it convenient for the operator to use and increasing the usability of the device.

[0148] Furthermore, using the shape of the hook 100 when it is in the working state (holding a tool), the height direction of the hook 100 is defined as the z direction, the length direction as the x direction, and the width direction as the y direction. After the rotation of the rotating assembly 200 is complete, the length of the hook 100 in the z direction can be set to be slightly larger than the groove depth of the receiving groove so that the locking groove 101 is correctly positioned parallel to the outer surface of the device (i.e., extending along the vertical direction). When the angle formed by the first fixing part 202 and the second fixing part 204 becomes 90°, the excess length of the hook 100 in the z direction locks onto the outer surface of the device, restricting the hook 100 from rotating further and achieving positioning of the hook 100. This improves the ease of use of the device.

[0149] Furthermore, based on the above-mentioned technical proposal, if the groove depth of the housing groove is greater than or equal to the z-direction length of the hook 100, when the hook 100 is housed inside the housing groove, the edge of the hook 100 will not protrude from the outer surface of the device, which is even more advantageous for the use of outdoor portable devices.

[0150] To optimize the above-mentioned technical proposal, and to ensure that the edge of the hook 100 does not protrude from the outer surface of the device when the hook 100 is housed inside the housing groove, while also achieving positional restriction for the hook 100, the present invention provides a first contact end 205 on the first connection part 201 and a second contact end 206 on the second connection part 203. When the angle formed by the first fixing part 202 and the second fixing part 204 becomes 90°, the first contact end 205 and the second contact end 206 come into contact.

[0151] Specifically, the first connecting portion 201 is cylindrical, and since the first connecting portion 201 needs to rotate, a clearance groove is provided in the second fixing portion 204 to avoid the first connecting portion 201, and the edge of the clearance groove is formed as the second contact end 206. The position of the first fixing portion 202 corresponding to the second contact end 206 is the first contact end 205, and the first contact end 205 is the contact surface formed on the first fixing portion 202. When the first fixing portion 202 rotates to a predetermined position, the second contact end 206 comes into contact with the contact surface, preventing the first fixing portion 202 from rotating any further, thereby creating a positional restriction on the rotating assembly 200.

[0152] In this way, a position-restricting structure is formed on the rotating assembly 200, allowing the hook 100 to be completely housed inside the housing groove, while also achieving position restriction. The design of the first contact end 205 and the second contact end 206 makes the outdoor portable device less prone to shaking and falling off when deployed. The cooperation of the first contact end 205 and the second contact end 206 provides the outdoor portable device with a stable support angle, ensuring the stability of the outdoor portable device during use. This improves the ease of use of the device.

[0153] To optimize the above-described technical proposal, the side to which the first fixing portion 202 of the hook 100 is connected is designated as the first side of the hook 100, and the side of the hook 100 positioned opposite the first side is designated as the second side of the hook 100. A pull cord is connected to the second side of the hook 100, and the pull cord is used to move the first fixing portion 202 away from the second fixing portion 204.

[0154] Specifically, depending on the user's needs, the pull cord may be a single string or a ring-shaped pull cord, both of which are intended to facilitate user operation.

[0155] Specifically, a fixing ring is provided on the first fixing part 202, and the pull cord is movably attached to the fixing ring, allowing the pull cord to be easily removed. Even when the operator is not using the pull cord, the hook 100 can be pulled out by pulling the fixing ring.

[0156] In the initial state, the pull cord, the hook 100, and the fixing surface are all located inside the storage groove. When the operator grasps and pulls the pull cord, the first fixing part 202 moves away from the second fixing part 204, and the hook 100 is pulled out of the storage groove as a result. When storage is required, the hook 100 is pushed back into the storage groove, and then the pull cord is pushed back into the storage groove. By providing a pull cord, a convenient operating method is provided for the operator, making the operation of the hook 100 more intuitive and simple, allowing the operator to easily deploy or store the hook 100, and improving the ease of use of the device.

[0157] Furthermore, the hook 100 may be elastically provided inside the housing groove. That is, a pressing member is provided inside the hook 100 and the housing groove. When in use, the user pushes the hook 100 inward, causing it to spring out from inside the housing groove, and the user pushes the hook 100 inward again, causing it to be stored inside the housing groove. The structure and connection method of the pressing member are conventional, so a detailed explanation is omitted here.

[0158] To optimize the aforementioned technical proposal, multiple structural forms exist for the implantation structure.

[0159] The outdoor equipment includes an equipment body and an insertion structure, and in some embodiments, the insertion structure includes a first insertion portion 303. The first insertion portion 303 is provided on the bottom or side wall of the equipment body, and the length of the first insertion portion 303 extends along the depth direction of the locking groove 101. By inserting the first insertion portion 303 and the locking groove 101, the equipment body can be hung on the hanger 100.

[0160] Furthermore, when the first insertion portion 303 is inserted into the locking groove 101, the tool can be hung on the hook 100 solely by the insertion of the first insertion portion 303 into the locking groove 101. In addition to the insertion of the first insertion portion 303 into the locking groove 101, the first insertion portion 303 can also be used to hold the tool by clamping the tool body and the groove wall of the locking groove 101, or by forming a double lock with the hole wall of the through hole 102. In other embodiments, the insertion structure further includes a second insertion portion 304, which is provided on the side wall or bottom of the tool body parallel to the first insertion portion 303. When the tool body is hung on the hook 100, the first insertion portion 303 and the second insertion portion 304 clamp the groove wall of the locking groove 101 of the hook 100 that is closest to the front surface 103. Alternatively, the first insertion portion 303 and the second insertion portion 304 clamp the hole wall of the through hole 102 of the hook 100, which is closest to the front surface 103.

[0161] In another embodiment, the insertion structure includes a bend-back portion 503, which is provided at the bottom of the first insertion portion 303. When the tool body is hung on the hook 100, the first insertion portion 303 is inserted into the locking groove 101, and the bend-back portion 503 comes into contact with the bottom surface, back surface 104, or front surface 103 of the hook 100.

[0162] Specifically, the bent-back portion 503 bends back along a direction approaching the top of the first insertion portion 303. The bent-back portion 503 may also bend back along a direction away from the device body. In this case, the bent-back portion 503 contacts the bottom surface and front surface 103 of the hook 100. Alternatively, the bent-back portion 503 may bend back in a direction approaching the device body. In this case, the bent-back portion 503 contacts the bottom surface and back surface 104 of the hook 100. When the bend is formed, the bent-back portion 503 contacts the connection point between the bottom surface and front surface 103 of the hook 100, or the connection point between the bottom surface and back surface 104 of the hook 100, and the waist shape design makes the locking of the bent-back portion 503 more stable.

[0163] In another embodiment, the insertion structure includes two first insertion portions 303 and two bending portions 503, and further includes a hinge. The hinge includes a first hinge portion 601, a second pivot shaft, and a second hinge portion 602, the first hinge portion 601 being connected to the tool body, the first hinge portion 601 and the second hinge portion 602 being rotatably connected by the second pivot shaft, and the second hinge portion 602 being connected to the first insertion portion 303. The first insertion portion 303 is rotatably connected to the tool body by the hinge.

[0164] Furthermore, the structural form of the above-described insertion structure can be flexibly applied to various types of tool bodies. Outdoor tools may consist of at least one of the following: a cup holder 300, a knife holder 400, a fishing rod holder 500, and a table board 600. The insertion structure and the type of tool body can be freely combined. For example, the cup holder 300 can be connected to the locking groove 101 using the first insertion part 303, or it can be connected to the locking groove 101 by providing the first insertion part 303 and the second insertion part 304. Only some combinations will be described below.

[0165] As shown in Figures 26-28, in order to optimize the above technical proposal, the tool body includes a cup holder 300, the cup holder 300 includes a first housing 301 and a second housing 302, the first housing 301 is fitted onto the second housing 302, and the second housing 302 is used to house a cup.

[0166] Specifically, the bottom of the first housing 301 is provided with a first insertion portion 303 that extends vertically.

[0167] Specifically, the cup holder 300 is used to meet the user's drinking water needs during outdoor activities.

[0168] Specifically, the cup holder 300 includes one or more placement sections, which are used to place cups. In the present invention, the first housing 301 is preferably a cavity structure, and the second housing 302 is provided with two placement sections, which are designed as cylindrical cavity structures.

[0169] Specifically, by adopting a structure in which the first housing 301 and the second housing 302 are fitted together, the support strength of the cup holder 300 can be increased.

[0170] During use, the first insertion portion 303 engages with the inside of the locking groove 101, fixing the cup holder 300 and the hook 100 relative to each other. Since the volume of the first insertion portion 303 is less than or equal to the volume of the locking groove 101, it can be filled into the locking groove 101. This ensures the connection strength between the cup holder 300 and the hook 100.

[0171] To optimize the above technical proposal, a second insertion portion 304 is provided at the bottom of the first housing 301, positioned parallel to the first insertion portion 303. The first insertion portion 303 and the second insertion portion 304 are used to clamp the groove wall of the locking groove 101.

[0172] Specifically, the distance between the second insertion portion 304 and the first insertion portion 303 is set to be equal to the thickness of the groove wall of the locking groove 101, so that when the first insertion portion 303 is engaged inside the locking groove 101, the locking groove 101 can be just gripped by the second insertion portion 304 and the first insertion portion 303.

[0173] Specifically, the volume of the second insertion portion 304 may be larger than the volume of the first insertion portion 303. This increases the support area of ​​the second insertion portion 304. By having the second insertion portion 304 and the first insertion portion 303 jointly bear the load, the groove wall of the locking groove 101 can be gripped more stably, and the cup holder 300 can be securely attached to an outdoor portable device.

[0174] Specifically, the height of the first insertion portion 303 and the height of the second insertion portion 304 are both greater than the length of the hook 100 in the z-direction. This ensures a stable connection to the hook 100. Furthermore, the height of the second insertion portion 304 is greater than the height of the first insertion portion 303. This prevents the first insertion portion 303 from slipping out of the locking groove 101.

[0175] Specifically, reinforcing ribs can be placed inside the first insertion portion 303 and the second insertion portion 304, thereby increasing the structural strength of the first insertion portion 303 and the second insertion portion 304 and ensuring their support capacity.

[0176] To optimize the above technical proposal, the bottoms of the first housing 301 and the second housing 302 are tapered and inclined downward in the vertical direction. Drainage holes 305 are also provided in the bottoms of the first housing 301 and the second housing 302.

[0177] Specifically, the bottoms of the first housing 301 and the second housing 302 have a tapered shape, which forms a water guide slope. When used in conjunction with the drain hole 305, water accumulated in the area where the second housing 302 is placed can be quickly drained, preventing bacterial growth and the generation of unpleasant odors, and improving the effectiveness of the cup holder 300.

[0178] During use, the first insertion part 303 and the second insertion part 304 clamp the groove wall of the locking groove 101, allowing the user to place the cup in any desired location. The support action of the first insertion part 303 and the second insertion part 304 keeps the cup holder 300 stable, and if water accumulates in the placement area, it is discharged through the drain hole 305 along the water guide slope. By designing the cup holder 300 in this way, a highly convenient drinking water solution is provided to the user, meeting the drinking water needs during outdoor activities and expanding the usage scenarios for outdoor portable devices.

[0179] To optimize the above technical proposal, a locking portion 309 is provided at the top of the first housing 301, and a locking hole is provided at the top of the second housing 302. When the first housing 301 and the second housing 302 are fitted together, the locking portion 309 engages with the locking hole. An axially bent portion 306 is provided on the side wall of the second housing 302. The protruding end of the bent portion 306 is provided on the axial side of the second housing 302. The top of the bent portion 306 is connected to the side wall of the second housing 302, and its bottom is suspended from the bottom of the second housing 302. An axially extending support plate 307 is connected to the bottom of the first housing 301. When a cup is housed inside the cup holder 300, the support plate 307 is in close contact with the bent portion 306. The first housing 301 further includes an L-shaped shielding plate 308. The first portion 3081 of the L-shaped shielding plate 308 is connected to the bottom of the first housing 301, and the second portion is connected to the support plate 307. When the support plate 307 is in close contact with the bent portion 306, the L-shaped shielding plate 308 seals the gap between the support plate 307 and the bent portion 306.

[0180] Specifically, preferably, there are six locking portions 309 and six locking holes, evenly distributed at the top of the first housing 301 and the top of the second housing 302, respectively. The positions of the locking portions 309 and the locking holes correspond to each other.

[0181] Specifically, the bent portion 306 is integrally molded with the side wall of the second housing 302, and a bending hole is provided in the side wall of the second housing 302 to accommodate the bent portion 306. The protruding end of the bent portion 306 protrudes inward into the storage area and is used to contact the cup. The support plate 307 is provided vertically at the bottom of the first housing 301. When in use, when the cup is placed inside the storage area, the protrusion of the bent portion 306 is positioned between the support plate 307 and the side wall of the cup, and is compressed to a certain angle (at this time, the shape of the protrusion is determined by the diameter of the cup), and fits into the bending hole. When the protrusion of the bent portion 306 is completely compressed, the diameter of the cup matches the diameter of the storage area, and at this time the bent portion 306 is completely housed in the bending hole and is in close contact with the support plate 307 and the side wall of the cup.

[0182] Specifically, the support plate 307 is used to support and protect the bent portion 306, and plays a role in making it less likely for the bent portion 306 to undergo brittle fracture when pressed by a larger cup. In addition, the L-shaped shielding plate 308 is used to fill the gaps that occur in the bent portion 306, the bent hole, and the support plate 307 after the first housing 301 and the second housing 302 have been assembled. Food residue and small fragments fall into the internal space of the first housing 301 and the second housing 302 through these gaps, preventing wastewater and waste from accumulating and contaminating the cup holder 300. This improves the sealing performance of the cup holder 300. Furthermore, the cooperation of the bent locking piece 306 and the support plate 307 allows the cup holder 300 to better adapt to various sizes of cups, improving the stability and sealing performance of the cup holder 300 itself, and preventing the cup from shaking or leaking when carried.

[0183] Furthermore, if the outer shell of the device has a groove with a larger space, the first insertion portion 303 and the second insertion portion 304 can be simultaneously engaged inside the groove, and the sides of the first insertion portion 303 and the second insertion portion 304 that are far apart from each other will abut against the two groove walls of the groove, thereby forming a fixed connection.

[0184] Referring to Figures 23 and 29, in order to optimize the above-described technical proposal, the tool body includes a knife holder 400, which comprises a top cover 401 and a holder body 402. The top cover 401 is fitted onto the top of the holder body 402, and a fastener 403 is filled inside the top cover 401, which is used to fasten a knife. A horizontally extending boss is provided on the outer wall of the top cover 401, and a horizontally extending mounting groove is provided on the top of the holder body 402. When the top cover 401 is fitted onto the top of the holder body 402, the boss and the mounting groove engage.

[0185] Preferably, the outer wall of the mounting groove is provided with a first insertion portion 303 parallel to the holder body 402, and the first insertion portion 303 cooperates with the holder body 402 to clamp the groove wall of the locking groove 101.

[0186] Specifically, the fastening device 403 is not particularly limited as long as it is made of a material capable of fastening a knife, such as stainless steel or alloy steel. In this invention, it is preferable to use a corrugated silicone knife ring as the fastening device 403, which allows the fastening device 403 to be elastically deformable and adaptable to the suspension of knives of various sizes and shapes. Furthermore, silicone is lightweight and has high abrasion resistance and corrosion resistance, making it convenient for the user to carry and use.

[0187] Specifically, reinforcing ribs may be provided inside the first insertion portion 303, thereby increasing the structural strength of the first insertion portion 303 and ensuring its support capacity.

[0188] Specifically, the top cover 401 and the holder body 402 can also be provided with the same connection method as the first housing 301 and the second housing 302. That is, multiple locking holes are provided on the outer wall of the top cover 401, and multiple locking parts 309 are provided on the inner wall of the top of the holder body 402, and the locking parts 309 are locked to the locking holes (the same connection method as between the locking parts 309 of the first housing 301 and the locking holes of the second housing 302), thereby connecting the top cover 401 and the holder body 402 and ensuring the connection stability of the knife holder 400.

[0189] Specifically, the engagement between the boss and the mounting groove allows for a more secure connection between the top cover 401 and the holder body 402, resulting in a more stable overall structure of the knife holder 400. Furthermore, the placement of the boss and mounting groove also provides mounting space for the installation of the first insertion portion 303.

[0190] Specifically, the holder body 402 has a hollow structure and is used to house the blade. The holder body 402 may be cup-shaped or have a through structure. If the holder body 402 has a through structure, the height of the holder body 402 is set to match the average length of the blade portion of commercially available blades, and the protective performance of the knife holder 400 is improved by isolating the sharp blade portion of the suspended blade inside the holder body 402.

[0191] Specifically, the height of the first insertion portion 303 is greater than the length of the outdoor portable device in the z-direction. This prevents the knife from slipping out of the locking groove 101 when subjected to a blade load, further enhancing the protective performance of the knife holder 400.

[0192] Specifically, the distance between the first insertion portion 303 and the holder body 402 is equal to the thickness of the groove wall of the locking groove 101. As a result, when the first insertion portion 303 is inserted into the locking groove 101, the locking groove 101 can be precisely gripped by the first insertion portion 303 and the holder body 402.

[0193] During use, the top cover 401 is fitted onto the top of the holder body 402, the locking portion 309 engages with the locking hole, and the boss and mounting groove engage with each other, thereby achieving a stable connection of the knife holder 400. The handle of the blade is locked to the upper surface of the locking device 403, and the blade surface of the blade is positioned inside the holder body 402. The first insertion portion 303 is positioned inside the locking groove 101 and, together with the holder body 402, clamps the groove wall of the locking groove 101, thereby fixing the knife holder 400 to the outdoor portable device. This configuration provides users with a convenient cutting tool usage solution and can meet the demand for cutting tools in outdoor activities. The design of the locking device 403 and boss / mounting groove ensures that the knife holder 400 can be securely suspended from the outdoor portable device, and the structure of the knife holder 400 expands the usage scenarios of the outdoor portable device, as it allows users to easily carry and use the blade.

[0194] Referring to Figures 23, 30, and 31, in order to optimize the above-described technical proposal, the tool body includes a fishing rod holder 500, which comprises a third housing 501 and a fourth housing 502. The third housing 501 is plate-shaped and is fixedly connected to the outer wall of the fourth housing 502. A first insertion portion 303 is provided at the top of the third housing 501. The first insertion portion 303 is connected to the third housing 501, and the bent-back portion 503 of the first insertion portion 303 is offset away from the third housing 501 and bent back towards the top of the first insertion portion 303. The fourth housing 502 is cylindrical, and a hanging groove 504 is provided at the top of the fourth housing 502 on the side farther from the third housing 501, which is used to hang and hold the tip of the fishing rod. When the fishing rod holder 500 is engaged with the locking groove 101, the first insertion portion 303 is inserted into the inside of the locking groove 101.

[0195] Specifically, the third housing 501 is fixedly connected to the outer wall of the fourth housing 502 by fasteners such as bolts, and the third housing 501 and the fourth housing 502 are connected in the front-to-back direction. The third housing 501 is positioned on the side closer to the outdoor portable device, and the fourth housing 502 is positioned on the side further away from the outdoor portable device. The fourth housing 502 is provided with threaded holes, which can be used for bolted connection with the third housing 501. Alternatively, studs are provided on the side of the fourth housing 502 closer to the third housing 501, with threaded holes formed inside, for bolted connection with the third housing 501. Furthermore, the structural strength of the fourth housing 502 can be increased by placing multiple reinforcing ribs on the side of the fourth housing 502 closer to the third housing 501.

[0196] Specifically, the bending return portion 503 is used to wrap around and lock onto the bottom of the locking groove 101, thereby improving the support effect of the fishing rod holder 500 on the fishing rod and the force-bearing effect of the fishing rod. This prevents the fishing rod from easily slipping out of the locking groove 101 when force is applied, and improves the user experience and stability when positioning the fishing rod.

[0197] During use, the third housing 501 is fixedly connected to the outer wall of the fourth housing 502, and the two are permanently connected. The first insertion portion 303 is inserted into the locking groove 101, and the bending return portion 503 is rotated upward in the vertical direction and inserted until it locks into the bottom of the locking groove 101. This creates a stable connection between the fishing rod holder 500 and the hook 100.

[0198] The design of the first insertion portion 303 of the present invention ensures that the fishing rod holder 500 is securely attached to the hook 100. The design of the hanging groove 504 allows the user to easily hang and remove the fishing rod. This provides the device with a convenient fishing gear usage solution, meeting the fishing rod carrying needs of fishing enthusiasts in outdoor activities. Furthermore, it expands the usage scenarios for outdoor portable devices.

[0199] Referring to Figures 22 and 32, in order to optimize the above technical proposal, the tool body includes a tabletop 600. Fixing holes are provided on the edge of the tabletop 600, and the first hinge portion 601 is connected to the fixing holes. When the tabletop 600 is engaged with the locking groove 101, the second hinge portion 602 is engaged inside the locking groove 101.

[0200] Specifically, the first hinge portion 601 is connected to the plate body 601, and the second hinge portion 602 engages with the locking groove 101. The axis of rotation is provided between the first hinge portion 601 and the second hinge portion 602, that is, the first hinge portion 601 and the second hinge portion 602 are rotatable about the axis of rotation.

[0201] Specifically, the first hinge portion 601 and the second hinge portion 602 are freely rotatable, with a maximum rotation angle of 270°. This allows for the mounting and use of the tabletop 600 to be met.

[0202] Specifically, the fixing holes may be screw holes, in which case the first hinge portion 601 is connected to the edge of the table plate 600 by fasteners such as bolts.

[0203] Specifically, a single tabletop 600 may have multiple hinges, and in the present invention, preferably, there are two hinges, which are evenly distributed along the longitudinal side edges of the tabletop 600, thereby improving the rotational stability of the tabletop 600.

[0204] Specifically, the second hinge portion 602 may have the same shape as the first insertion portion 303, which further improves the locking stability with the locking groove 101.

[0205] During use, the second hinge portion 602 engages with the locking groove 101, bends back to the bottom of the locking groove 101 and locks in place, causing the plate body 601 to rotate 90° and be positioned perpendicular to the side of the device. As a result, the table plate 600 becomes horizontal, allowing the user to work on the table plate 600.

[0206] The second hinge portion 602 of the present invention can be reliably bent back and hooked onto the bottom of the hanger 100 when subjected to force, thereby providing better support for the load of the placed item. This prevents the tabletop 600 from easily sliding out of the locking groove 101 when subjected to force. Furthermore, the design of the hinge and locking groove 101 ensures that the tabletop 600 is securely suspended from the hanger 100, improving the user experience and effectiveness when placing items. As a result, the usage scenarios for outdoor portable devices are further expanded.

[0207] The aforementioned device body is easy to attach to and detach from the hanging device 100, which makes storage and packaging convenient, improves the usability of the device body, and reduces packaging costs.

[0208] As described above, the aforementioned proposals work together to form a highly functional and user-friendly portable outdoor device. By providing a variety of combinations of hanging devices 100 and the device body, this system can meet the diverse needs of users during outdoor activities, such as storage, drinking, cutting, fishing, and resting, and expand the usage scenarios of the portable outdoor device.

[0209] Figures 33-39 show portable devices provided in another embodiment of the present invention.

[0210] Referring to Figures 33, 34, and 35, the outdoor portable table 10 provided in one embodiment of the present invention can be used in combination with an outdoor mobile device such as a portable mobile refrigerator 20. The external housing of the refrigerator 20 is provided with an insertion space 21, which may be a hole structure or a groove structure. The outdoor portable table 10 includes a table unit 101, which comprises a support 100, support legs 200, and connectors 300. The support 100 includes a first table plate 110 and a second table plate 120, with the first table plate 110 positioned closer to the refrigerator 20 than the second table plate 120. The second table plate 120 is movably connected to the first table plate 110, for example, the second table plate 120 is rotatably connected to the end of the first table plate 110 that is farther from the outdoor mobile device, and the two may be rotatably connected by a mechanism such as a hinge. Furthermore, the second table plate 120 may be slidably connected to the first table plate 110, and the second table plate 120 is slidably connected along the thickness direction of the first table plate 110, that is, in a direction perpendicular to the plate surface.

[0211] Referring to Figures 36, 37, and 38, during the rotation process, the first table plate 110 and the second table plate 120 may be folded and positioned relative to each other along the thickness direction of the first table plate 110, or they may be arranged along the same plane, that is, the first table plate 110 and the second table plate 120 may be flush with each other. That is, the first table plate 110 and the second table plate 120 unfold relative to each other and become coplanar. The support legs 200 are rotatably connected to the second table plate 120. During the rotation process, the support legs 200 can be folded and positioned on the second table plate 120, or the support legs 200 can be brought into contact with a support surface such as the ground, thereby allowing the support legs 200 to support the support 100. Of course, the support legs 200 may also be of a telescopic structure, and the retracted support legs 200 can be folded and positioned on the second table plate 120. The connector 300 is movably mounted on the first table plate 110 and is used to removably connect to the refrigerator 20. For example, the connector 300 is secured to the refrigerator 20 by being inserted into the insertion space 21 of the refrigerator 20. In other embodiments, the connector 300 may be removably connected to the refrigerator 20 by a method such as a locking connection.

[0212] When the connector 300 is attached to the refrigerator 20, the refrigerator 20 supports the first tabletop 110 via the connector 300. Also, since the support legs 200 support the second tabletop 120, both the refrigerator 20 and the support legs 200 jointly support the support 100. Therefore, when the first tabletop 110 and the second tabletop 120 are unfolded relative to each other, and the support 100 is jointly supported by the refrigerator 20 and the support legs 200, the outdoor portable table 10 is in a fully unfolded state, and food can be easily placed on the first tabletop 110 and the second tabletop 120. On the other hand, when the connector 300 is removed from the refrigerator 20, the support legs 200 are folded and placed on the second tabletop 120, and the first tabletop 110 and the second tabletop 120 are folded relative to each other, the entire outdoor portable table 10 is in a fully folded state. In this way, the volume of the outdoor portable table 10 is reduced, making it easier to store, package, transport, and carry, ultimately improving the usability of the outdoor portable table 10. In addition, the refrigerator 20 supports the first table plate 110 via the connector 300, that is, the support function of the refrigerator 20 is fully utilized. This reduces the number of support legs 200 used, thereby lowering the manufacturing cost of the outdoor portable table 10.

[0213] Referring to Figures 35, 36, and 39, in some embodiments, the support 100 further comprises a first position regulating device 140. When the outdoor portable table 10 is fully extended, the first table plate 110 has a first back surface 111 that faces the support surface. That is, the surface of the first table plate 110 opposite to the support surface is the table surface, which is used for placing food. The table surface and the first back surface 111 are two surfaces that face opposite each other in the thickness direction. The first position regulating device 140 is mounted on this first back surface 111 and is fixed to the first back surface 111 by means of, for example, bolt connection. The first position regulating device 140 is provided with a position regulating hole 141. The position regulating hole 141 extends along the alignment direction when the first table plate 110 and the second table plate 120 are extended. The position regulating hole 141 is claw-fitted with the connector 300. As a result, the connector 300 can slide and rotate relative to the position regulating hole 141. The connector 300 has a bent shape, and therefore its central axis is curved and located in the same plane. When the plane on which the central axis of the connector 300 is located is perpendicular to the first back surface 111, the connector 300 can be inserted into the insertion space 21. On the other hand, when the plane on which the central axis of the connector 300 is located is parallel to the first back surface 111, the connector 300 is folded and positioned on the first back surface 111.

[0214] Referring to Figures 35, 36, and 39, in some embodiments, the connector 300 includes a fitting step 310 and a hanging step 320, which are connected to each other at an angle. The fitting step 310 is gap-fitted with a position regulating hole 141. By rotating and sliding the fitting step 310 relative to the position regulating hole 141, when the outdoor portable table 10 is fully extended, the hanging step 320 is located outside the first back surface 111 and is inserted into the insertion space 21, thereby mounting the entire connector 300 to the refrigerator 20. On the other hand, when the outdoor portable table 10 is fully folded, the hanging step 320 is completely folded and positioned on the first back surface 111, and the hanging step 320 is completely covered by the first back surface 111. This configuration prevents a portion of the hanging shelf 320 from being exposed outside the coverage area of ​​the first back panel 111, further reducing the volume of the outdoor portable table 10 when it is fully folded, thereby further improving the usability of the outdoor portable table 10.

[0215] Referring to Figures 35, 36, and 39, in some embodiments, the connector 300 further comprises a contact step 330, which is connected at an angle to the end of the fitting step 310 on the side furthest from the hanging step 320. For example, the contact step 330 may be perpendicular to the fitting step 310. The hanging step 320 includes a first connecting portion 321, a second connecting portion 322, and a third connecting portion 323, which are connected in order, with both ends of the second connecting portion 322 connected to the first connecting portion 321 and the third connecting portion 323, respectively. That is, the second connecting portion 322 is connected between the first connecting portion 321 and the third connecting portion 323. The second connecting portion 322 is connected at an angle to the first connecting portion 321 and the third connecting portion 323. For example, the second connecting portion 322 may be perpendicular to both the first connecting portion 321 and the third connecting portion 323. In this way, the entire hanging shelf 320 has a roughly U-shaped structure. The first connecting part 321 is connected to the fitting step 310 at an angle. For example, the first connecting part 321 is perpendicular to the fitting step 310, and the second connecting part 322 is parallel to the fitting step 310. The third connecting part 323 is inserted into the insertion space 21. The third connecting part 323, the first connecting part 321, and the abutment step 330 may be parallel to each other. When the outdoor portable table 10 is fully extended, the abutment step 330 is located outside the position regulating hole 141 and abuts against one end of the first position regulating device 140. As a result, the hanging shelf 320 is positioned outside the first back surface 111, the third connecting part 323 is inserted into the insertion space 21, and the second connecting part 322 is located outside the insertion space 21 and placed on the refrigerator 20. On the other hand, when the outdoor portable table 10 is fully folded, all of the hanging shelves 320 are folded and positioned on the first back surface 111, and the first connecting portion 321 is located outside the position regulating hole 141 and abuts against the other end of the first position regulating device 140.

[0216] Referring to Figures 35, 36, and 39, the contact step 330 and the first connecting portion 321 provide a good positional regulating effect to the entire connector 300, preventing the connector 300 from detaching from the positional regulating hole 141 and the first table plate 110. This avoids the risk of the connector 300 being lost when stored alone, ensures that the connector 300 is always positioned on the first table plate 110, and improves the usability of the outdoor portable table 10. Furthermore, in the process of converting the outdoor portable table 10 from a fully folded state to a fully unfolded state, when the fitting step 310 slides against the positional regulating hole 141 and the contact step 330 comes into contact with the first positional regulating device 140, the hanging step 320 is positioned outside the first back surface 111. At this time, since the plane on which the hanging step 320 is located is parallel to the first back surface 111, by rotating the fitting step 310 90° relative to the position regulating hole 141, the plane on which the hanging step 320 is located can be made perpendicular to the first back surface 111, making it easier to insert the third connecting part 323 into the insertion space 21. Also, in the process of the outdoor portable table 10 transitioning from a fully unfolded state to a fully folded state, since the plane on which the hanging step 320 is located is perpendicular to the first back surface 111, by rotating the fitting step 310 90° relative to the position regulating hole 141, the plane on which the hanging step 320 is located can be made parallel to the first back surface 111. After that, by sliding the fitting step 310 relative to the position regulating hole 141 and moving it until the first connecting part 321 contacts the first position regulating device 140, the entire hanging step 320 can be folded and placed on the first back surface 111. Therefore, by having the contact step 330 and the first connecting part 321 contact both ends of the first position regulating device 140, the position of the hanging step 320 relative to the first back surface 111 can be reliably defined whether the outdoor portable table 10 is in a fully extended state or a fully folded state. In this way, the ease of use of the outdoor portable table 10 can be further improved.

[0217] In other embodiments, for example, the connector 300 may be a structure such as a hook, and this hook may be fixedly connected to the first table plate 110. Alternatively, the connector 300 may be configured as a three-dimensional structure, in which case the central axis of the connector 300 will not be located in the same plane.

[0218] Referring to Figures 37 and 38, in some embodiments, the table unit 101 further comprises a locking member 400 and a first fastener 510. The locking member 400 is rotatably connected to the first table plate 110. With the outdoor portable table 10 in a fully unfolded state, one end of the locking member 400 is rotatably connected to the end of the first table plate 110 furthest from the second table plate 120, and the first fastener 510 is fixed to the end of the second table plate 120 furthest from the first table plate 110. The first fastener 510 may be a screw, a pin, or the like. When the first table plate 110 and the second table plate 120 are folded and positioned relative to each other, the other end of the locking member 400 is fixedly connected to the second table plate 120 via the first fastener 510. This configuration effectively restrains the first table plate 110 and the second table plate 120, preventing them from rotating relative to each other when fully folded, thereby ensuring the stability and reliability of the outdoor portable table 10 when it is fully folded.

[0219] Referring to Figures 37 and 38, in some embodiments, the table unit 101 further comprises a second fastener 520. The second fastener 520 may be a screw, a pin, or the like. Assuming the outdoor portable table 10 is in a fully unfolded state, the second fastener 520 is provided at the end of the first table plate 110 furthest from the second table plate 120. When the outdoor portable table 10 is in a fully unfolded state, the other end of the locking member 400 is fixedly connected to the first table plate 110 via the second fastener 520. This fixes both ends of the locking member 400, ensuring that the locking member 400 is securely attached to the first table plate 110. This prevents the other end of the locking member 400 from becoming a free end and swinging freely, thus preventing the swinging of the locking member 400 from interfering with the refrigerator 20 or the user. Furthermore, this configuration can further improve the usability of the outdoor portable table 10.

[0220] Referring to Figures 36 and 38, in some embodiments, the support 100 further comprises a second position regulating device 150. When the outdoor portable table 10 is fully extended, the second tabletop 120 has a second back surface 121 that faces the support surface. That is, the surface of the second tabletop 120 opposite to the support surface is the table surface, which is used for placing food. The table surface and the second back surface 121 are two surfaces of the second tabletop 120 that face opposite each other in the thickness direction. The second position regulating device 150 is mounted on this second back surface 121 and is fixed to the second back surface 121 by means of, for example, bolt connection. The second position regulating device 150 is provided with a position regulating groove 151, and the support leg 200 is rotatably connected to the second position regulating device 150. As a result, the support leg 200 is rotatably fitted with the position regulating groove 151. When the outdoor portable table 10 is fully extended, the support legs 200 rotate to their maximum position, away from the second tabletop 120. That is, the support legs 200 rotate to the position where the angle between the support legs 200 and the second tabletop 120 is maximized, away from the second tabletop 120. At this time, the inner wall surface of the position regulating groove 151 comes into contact with the support legs 200. This effectively restricts the rotation of the support legs 200, allowing them to exert an effective support function against the second tabletop 120. When it is necessary to convert the outdoor portable table 10 from the fully extended state to the fully folded state, the support legs 200 can first be rotated toward the second tabletop 120. In this case, the groove opening of the position regulating groove 151 provides good relief for the rotation of the support legs 200, preventing the second position regulating device 150 from hindering the rotation of the support legs 200 toward the second tabletop 120. When the support legs 200 come into contact with the second table plate 120 and are folded and positioned on the second back surface 121, the support legs 200 and the second table plate 120 are folded relative to each other. In this state, the first table plate 110 and the second table plate 120 can rotate to a position where they are folded relative to each other, thereby positioning the support legs 200 between the first table plate 110 and the second table plate 120.Therefore, the support legs 200 can make full use of the space between the first table plate 110 and the second table plate 120, further reducing the volume of the outdoor portable table 10 when it is fully folded and further improving the ease of use of the outdoor portable table 10. Also, when the first table plate 110 and the second table plate 120 are folded and arranged relative to each other, the second position regulating device 150 comes into contact with the first table plate 110, thereby effectively restricting the rotation of the first table plate 110 in the direction toward the second table plate 120. Therefore, when the outdoor portable table 10 is fully folded, the planes on which the first table plate 110 and the second table plate 120 are located are almost parallel.

[0221] Referring to Figures 36 and 38, in some embodiments, the support 100 further comprises a chuck 160. The chuck 160 is fixed to the second back surface 121 by means of, for example, a bolt connection. The chuck 160 is provided with a chuck groove 161. When the support legs 200 are folded and positioned on the second back surface 121, the chuck groove 161 and the support legs 200 form a tight fit relationship, that is, the support legs 200 and the chuck 160 form a detachable locking connection relationship. Therefore, when the outdoor portable table 10 is in a fully folded state, the chuck 160 can effectively fix the support legs 200, preventing the support legs 200 from causing slight swinging that would impact the first table plate 110 and the second table plate 120 or generate noise. As a result, the comfort of transporting the outdoor portable table 10 can be improved.

[0222] Referring to Figures 34 and 35, in some embodiments, elongated mounting grooves 130 are provided on the table surfaces of the first table plate 110 and / or the second table plate 120. For example, elongated mounting grooves 130 may be provided on the table surfaces of both the first table plate 110 and the second table plate 120. The mounting grooves 130 may be through grooves that penetrate the first table plate 110 and the second table plate 120 in the thickness direction. That is, the mounting grooves 130 have openings on both the first back surface 111 and the second back surface 121. By providing the mounting grooves 130, it becomes possible to insert or suspend various articles within the mounting grooves 130, thereby improving the versatility of the outdoor portable table 10's functionality.

[0223] Referring to Figures 33 and 34, in some embodiments, the second table plate 120 is provided with a through hole 122. The through hole 122 penetrates the second table plate 120 along the thickness direction, and therefore the through hole 122 has an opening on both the table surface and the second back surface 121 of the second table plate 120. Assuming the outdoor portable table 10 is in a fully unfolded state, the through hole 122 is provided at the end of the second table plate 120 that is close to the first table plate 110. If the outdoor portable table 10 includes multiple table units 101, the multiple table units 101 can be connected to each other. This allows the overall area of ​​the table surface of the outdoor portable table 10 to be increased. By providing through holes 122 for two adjacent table units 101 in the outdoor portable table 10, the connector 300 of one table unit 101 can be inserted into the through hole 122 of the other table unit 101. In other words, by inserting the third connecting portion 323 of the connector 300 into the through hole 122, connection between two adjacent table units 101 can be achieved. Therefore, by providing the through hole 122 and the connector 300, it is possible to connect multiple table units 101 in the outdoor portable table 10 according to actual needs. In other embodiments, the through hole 122 may be replaced with a through groove.

[0224] Referring to Figures 36 and 37, in some embodiments, the outdoor portable table 10 is further equipped with a handle 610. The handle 610 is provided on the side of the first table plate 110 or the second table plate 120. By providing the handle 610, when the outdoor portable table 10 is fully folded, the user can carry the outdoor portable table 10 via the handle 610, thereby improving the ease of use of the outdoor portable table 10.

[0225] Referring to Figures 36 and 37, for example, the outdoor portable table 10 further includes positioning devices 620. There are two positioning devices 620. The handle 610 is elongated and has two sliding grooves 611. There is a one-to-one correspondence between the positioning devices 620 and the sliding grooves 611, and the two sliding grooves 611 are provided at opposite ends of the handle 610. The positioning devices 620 are provided through the handle 610 and the sliding grooves 611, and the positioning devices 620 are slidably fitted into the sliding grooves 611. The positioning devices 620 are fixedly connected to the first table plate 110 or the second table plate 120, and the handle 610 is connected to the first table plate 110 or the second table plate 120 via the positioning devices 620. This prevents the handle 610 from falling off the first table plate 110 or the second table plate 120. As the positioning device 620 slides against the slide groove 611, it can contact two opposing ends of the slide groove 611. For example, when the pulling force applied to the handle 610 is stopped, the two positioning devices 620 contact the nearest ends of the slide groove 611, causing the handle 610 to be in close contact with the first table plate 110 or the second table plate 121, preventing the handle 610 from protruding and interfering with the first table plate 110 or the second table plate 121. On the other hand, when a pulling force is applied to the handle 610, the two positioning devices 620 contact the furthest ends of the slide groove 611, creating sufficient clearance between the handle 610 and the first table plate 110 or the second table plate 120, making it easier for the user to grasp the handle 610. This configuration further improves the usability of the outdoor portable table 10.

[0226] Referring to Figures 33 and 34, in some embodiments, the present invention can further provide an outdoor device 30. The outdoor device 30 includes an outdoor mobile device and an outdoor portable table 10. The outdoor mobile device may be a portable mobile refrigerator 20. The refrigerator 20 is provided with an insertion space 21. The connector 300 fits into the insertion space 21, and a detachable connection relationship is realized between the connector 300 and the refrigerator 20.

[0227] The technical features in the embodiments described above can be used in any combination. For the sake of brevity, not all possible combinations of the technical features in the embodiments are described in detail, but all such combinations of technical features are understood to fall within the scope described herein, as long as they do not contradict each other.
