Description

Technical Field

[0001] This utility model relates to the field of outdoor storage equipment technology, and in particular to an exoskeleton-type support mechanism and a multi-functional vehicle. Background Technology

[0002] Outdoor photographers, outdoor sketchers, and outdoor office workers need equipment such as trolleys, storage bags, and tables when they travel. However, due to the incompatibility between different products and their large size and heavy weight, outdoor workers face great inconvenience when traveling.

[0003] Existing trolleys or suitcases with folding desktops either have complex structures resulting in small actual storage space, limited usable desktop area after unfolding leading to insufficient practicality, or large overall size resulting in poor portability. Utility Model Content

[0004] Given that existing outdoor storage devices with folding desktops have shortcomings in balancing effective storage volume, desktop usable area, and portability, it is necessary to provide an exoskeleton-style support mechanism and a multi-functional vehicle.

[0005] This application provides an exoskeleton-type support mechanism, including:

[0006] A frame assembly, including an upper frame, a lower frame, and a plurality of connecting rods connecting the upper frame and the lower frame to form a storage space for accommodating a storage bag;

[0007] A first tabletop, rotatably mounted to the upper frame, has a first supporting surface and a first insertion hole located at the edge of the first supporting surface; and

[0008] The second tabletop has a second support surface and a plug-in end located at the edge of the second support surface;

[0009] The exoskeleton support mechanism has a stowed state and an unfolded state. When the exoskeleton support mechanism is in the stowed state, the first tabletop, the second tabletop, and the frame assembly are stacked on top of each other. When the exoskeleton support mechanism is in the unfolded state, the plug-in end is inserted into the first plug hole to connect with the first tabletop, and the first support surface and the second support surface are flush to form a tabletop.

[0010] This design, through the cooperation of the first socket and the plug end, further expands the desktop, increasing the desktop area and thus meeting the user's needs for placing equipment outdoors. In the storage state, the two tabletops and frame components are stacked on top of each other, occupying less overall space. It also takes into account the user's need for portability for this type of outdoor storage device. The tabletops do not intrude into the storage space when stored, and the volume of the storage space does not decrease, which helps to avoid squeezing the storage bag.

[0011] In one embodiment, the first tabletop includes a first plate providing the first supporting surface and a first limiting strip fixedly connected to the first plate. The outer edge of the first plate is provided with a first notch, and the first limiting strip is fixedly disposed on the outer edge of the first plate to form the first insertion hole with the first notch.

[0012] The second tabletop includes a second plate providing the second support surface and a protrusion fixedly connected to the second plate.

[0013] When the exoskeleton support mechanism is in the unfolded state, the second plate abuts against the first limiting strip, and the protrusion is inserted into the first insertion hole and abuts against the side of the first plate away from the first support surface and the inner side of the first limiting strip.

[0014] With this configuration, the first limiting strip and the first plate limit the protrusion from the vertical and horizontal directions, respectively. Since the first support surface and the second support surface are flush, it can be understood that the first plate also limits the second plate from the horizontal direction. In this way, the first tabletop and the second tabletop will not easily separate after they are connected.

[0015] In one embodiment, the first limiting strip is located on the side of the first tabletop away from the first supporting surface;

[0016] The second plate includes a support portion and a plug portion located at the edge of the support portion, and the protrusion is fixedly connected to the side of the plug portion opposite to the second support surface;

[0017] When the exoskeleton support mechanism is in the unfolded state, the plug is inserted into the first notch and abuts against the upper side of the first limiting strip.

[0018] This configuration, through this splicing and assembly method, forms the shapes of the first and second tabletops, facilitating processing and production.

[0019] In one embodiment, the shape of the insertion portion matches the shape of the first notch.

[0020] With this configuration, when unfolded, the gap between the first and second tabletops is small, the connection is firm and stable, and it is not easy to wobble.

[0021] In one embodiment, the exoskeleton-type support mechanism further includes a third tabletop, which is installed on the side of the upper frame away from the lower frame and has a third support surface; the first support surface, the second support surface and the third support surface are flush to form a tabletop.

[0022] This setup further utilizes the space above the frame components, resulting in a larger usable area on the final desktop.

[0023] In one embodiment, the second tabletop further has a second insertion hole located at the edge of the second support surface, and there are at least two second tabletops, the second insertion hole being used for insertion of the insertion end of another second tabletop.

[0024] With this setup, the second tabletop can be extended outwards, allowing users to customize their desktop according to their needs and preferences.

[0025] In one embodiment, the exoskeleton-like support mechanism further includes a first table leg rotatably mounted to the first tabletop and a second table leg rotatably mounted to the second tabletop.

[0026] This design, with its legs, facilitates support of the tabletop when the legs are extended, and the foldable legs make storage easier, reducing the overall size of the exoskeleton-style support mechanism.

[0027] In one embodiment, the exoskeleton support mechanism further includes multiple clamp groups, each clamp group comprising a snap clamp and a locking clamp;

[0028] At least one of the clamps is installed on the first tabletop, wherein the locking clamp is fitted onto the upper frame and the snap clamp is used to snap onto the lower frame.

[0029] This design, through the combination of clip-on and locking clamps, facilitates the assembly and disassembly of the tabletop and frame components.

[0030] In one embodiment, the first tabletop has a first bolt hole, and the second tabletop has a second bolt hole corresponding to the position of the first bolt hole. The exoskeleton support mechanism also includes fastening bolts. When the exoskeleton support mechanism is in the retracted state, the fastening bolts pass through the first bolt hole and the second bolt hole.

[0031] This design makes it easy to store the second tabletop, and the use of fastening bolts ensures a stable connection between the second and first tabletops when stored, preventing wobbling.

[0032] This application also provides a multi-functional vehicle, including:

[0033] Such as the exoskeleton-type support mechanism described above;

[0034] The tie rod assembly is installed at both ends on the upper and lower frames of the exoskeleton support mechanism, respectively;

[0035] A roller assembly is mounted on the lower frame of the exoskeleton-type support mechanism; and

[0036] The storage bag is installed within the receiving space of the exoskeleton-type support mechanism.

[0037] This design, with the pull rod and roller assembly working together, makes it easy for users to move this multi-functional vehicle. Users can also add different storage bags according to their outdoor work needs, making it convenient for self-customization. Attached Figure Description

[0054] Outdoor workers require storage equipment that is large-capacity, portable, and multifunctional to easily cope with complex outdoor environments. For users engaged in outdoor photography, sketching, or office work, the storage equipment also needs to have a desktop support function for convenient placement of professional equipment such as cameras and computers.

[0055] Products on the market designed for this type of outdoor storage need include rolling suitcases with built-in folding panels. These transform the two side walls of a regular rolling suitcase into flip-up tables, allowing users to expand the top surface of the suitcase for convenient device placement. However, the area that can be expanded into a tabletop is still limited, and it depends on the shape of the suitcase itself. As the size of the suitcase decreases, the expanded area also decreases, thus failing to meet the user's needs.

[0056] Given the limited desktop expansion area of ​​current expandable suitcases, it is necessary to provide an exoskeleton-style support mechanism and multi-functional vehicle that allows for further desktop expansion and greater portability.

[0057] Please see Figure 1 and Figure 2 , Figure 1 This is a structural diagram of a multi-functional vehicle in one embodiment of this application when the exoskeleton support mechanism is in a stowed state. Figure 2 for Figure 1 The diagram shows the structure of the multi-functional vehicle in its deployed exoskeleton support mechanism. This multi-functional vehicle includes an exoskeleton support mechanism, a pull rod assembly 60, a roller assembly 70, and a storage bag (not shown, any bag that can be housed within the storage space 101 of the exoskeleton support mechanism). The two ends of the pull rod assembly 60 are respectively mounted on the upper frame 11 and lower frame 12 of the exoskeleton support mechanism, and the rollers are mounted on the lower frame 12. The pull rod assembly 60 and roller assembly 70 work together to achieve the function of a traditional rolling suitcase. The storage space 101 of the exoskeleton support mechanism provides a mounting position for the storage bag, facilitating the adaptation of different models of storage bags. Users can choose different storage bags according to their outdoor work needs, enabling customization. Considering the limited desktop expansion area, this application further expands the desktop of the exoskeleton support mechanism.

[0058] Please see Figure 2The exoskeleton-type support mechanism includes a frame assembly 10, a first tabletop 21, and a second tabletop 22. The frame assembly 10 includes an upper frame 11, a lower frame 12, and a connecting rod 13. The upper frame 11, lower frame 12, and connecting rod 13 are connected to form a storage space 101 for accommodating a storage bag. The upper frame 11, lower frame 12, and connecting rod 13 can be connected by a four-way adapter. The first tabletop 21 is rotatably mounted on the upper frame 11 and has a first support surface 2101 and a first insertion hole 2102 located at the edge of the first support surface 2101. The second tabletop 22 has a second support surface 2201 and an insertion end 2202 located at the edge of the second support surface 2201. The insertion end 2202 is used to engage with the first insertion hole 2102 at the edge of the first tabletop 21 to connect the first tabletop 21 and the second tabletop 22. This exoskeleton-style support mechanism has a stowed state and an unfolded state. When the exoskeleton-style support mechanism is in the stowed state, the first tabletop 21, the second tabletop 22, and the frame assembly 10 are stacked on top of each other. When the exoskeleton-style support mechanism is in the unfolded state, the plug-in end 2202 is inserted into the first plug hole 2102 to connect with the first tabletop 21, and the first support surface 2101 and the second support surface 2201 are flush to form a tabletop. The exoskeleton-style support mechanism provided in this application further expands the tabletop by cooperating with the first plug hole 2102 and the plug-in end 2202, thereby increasing the tabletop area and meeting the user's needs for placing equipment outdoors. In the stowed state, the two tabletops and the frame assembly 10 are stacked on top of each other, occupying less overall space, while also taking into account the user's need for portability of this type of outdoor storage device. The tabletops do not intrude into the storage space 101 when stowed, and the volume of the storage space 101 does not decrease, which helps to avoid squeezing the storage bag.

[0059] like Figure 1 As shown, optionally, in order to facilitate the storage of the second tabletop 22, in one embodiment provided in this application, the first tabletop 21 and the second tabletop 22 are respectively provided with a first bolt hole 2103 and a second bolt hole 2203 that are corresponding to each other. The exoskeleton support mechanism also includes a fastening bolt 50. When the exoskeleton support mechanism is in the storage state, the fastening bolt 50 passes through the first bolt hole 2103 and the second bolt hole 2203 and fixes the second tabletop 22 on the first tabletop 21.

[0060] Please see Figure 2 , Figure 3 and Figure 4 , Figure 3 for Figure 2 A structural diagram of the first tabletop 21. Figure 4 for Figure 2A schematic diagram of the structure of the second tabletop 22. Optionally, in one embodiment provided in this application, the first tabletop 21 includes a first plate body 211 and a first limiting strip 212. The first plate body 211 provides the aforementioned first support surface 2101, and the outer edge of the first plate body 211 is also provided with a first notch 2111. The first limiting strip 212 is fixed to the outer edge of the first plate body 211 and forms the aforementioned first insertion hole 2102 with the first notch 2111. The second tabletop 22 includes a second plate body 221 and a protrusion 222. The second plate body 221 provides a second support surface 2201, and the protrusion 222 constitutes part of the insertion end 2202 on the second tabletop 22. When the exoskeleton-type support mechanism is in the deployed state, the second plate 221 abuts against the first limiting strip 212, and the protrusion 222 is inserted into the first insertion hole 2102 and abuts against the side of the first plate 211 opposite to the first support surface 2101 and the inner side of the first limiting strip 212. In other words, the first limiting strip 212 and the first plate 211 limit the protrusion 222 from the vertical and horizontal directions, respectively. Since the first support surface 2101 and the second support surface 2201 are flush, it can be understood that the first plate 211 also limits the second plate 221 from the horizontal direction. Thus, the first tabletop 21 and the second tabletop 22 will not easily separate after being connected. Optionally, there can be multiple first notches 2111, and they can be located on different sides of the first tabletop 21, such as... Figure 2 As shown in the illustrated embodiment, the second tabletop 22 is installed on the side edge of the first tabletop 21. In other embodiments, the second tabletop 22 can also be installed on the lower edge of the first tabletop 21, thereby adapting to different user needs in actual use.

[0061] Please see Figure 4 The second tabletop 22 also has a second insertion hole 2205 located at the edge of the second support surface 2201. There are at least two second tabletops 22, and the second insertion hole 2205 is used for inserting the insertion end 2202 of another second tabletop 22. In this way, the second tabletop 22 can further extend the desktop, allowing users to customize the desktop according to their actual needs and preferences. It is understood that the second tabletop 22 also includes a second limiting strip 223. The second plate body 221 has a second notch 2213, which, together with the second limiting strip 223, forms the aforementioned second insertion hole 2205, facilitating standardized production. The second limiting strip 223 can also be installed on the lower surface of the second plate body 221 for easy assembly.

[0062] Please refer to the following: Figure 2 , Figure 3 , Figure 4 and Figure 5 , Figure 5 for Figure 2The diagram shows the structure of the multi-functional vehicle from another perspective. Specifically, in this embodiment provided in this application, the first limiting strip 212 is located on the side of the first tabletop 21 away from the first support surface 2101, that is, on the lower surface of the first tabletop 21 in the unfolded state. The second plate 221 includes a support portion 2211 and a plug portion 2212. The plug portion 2212 is located at the edge of the support portion 2211 and corresponds to the first notch 2111. The protrusion 222 is fixedly connected to the side of the plug portion 2212 away from the second support surface 2201, that is, on the lower surface of the second tabletop 22 in the unfolded state. The insertion end 2202 of the second tabletop 22 is formed by the insertion part 2212 and the insertion part 2212. When the exoskeleton support mechanism is in the unfolded state, the insertion part 2212 is inserted into the first notch 2111 and abuts against the upper side of the first limiting strip 212. This not only makes the first support surface 2101 and the second support surface 2201 flush, but also makes the connection between the first tabletop 21 and the second tabletop 22 in the unfolded state more secure. In actual assembly, the insertion end 2202 of the second tabletop 22 is inserted obliquely into the first insertion hole 2102 of the first tabletop 21, and then the second tabletop 22 is flattened to complete the splicing and expansion of the tabletop. Furthermore, in order to avoid misalignment between the second tabletop 22 and the first tabletop 21, the shape of the insertion part 2212 matches the shape of the first notch 2111.

[0063] Please refer to the following: Figure 1 , Figure 2 and Figure 3 Optionally, in one embodiment provided in this application, the exoskeleton support mechanism further includes a third tabletop 23, which is installed on the side of the upper frame 11 opposite to the lower frame 12 and has a third support surface 2301; the first support surface 2101, the second support surface 2201, and the third support surface 2301 are flush to form a tabletop. This further utilizes the space above the frame assembly 10, resulting in a larger usable area of ​​the final tabletop. Optionally, the third tabletop 23 also has a clearance groove on the side near the pull rod assembly 60 to allow space for the pull rod.

[0064] Please see Figure 2 and Figure 5Optionally, in one embodiment provided in this application, the exoskeleton support mechanism further includes a first table leg 31 rotatably mounted on the first tabletop 21 and a second table leg 32 rotatably mounted on the second tabletop 22. The table legs facilitate support of the tabletop when the legs are extended, and the foldable legs facilitate storage, reducing the overall size of the exoskeleton support mechanism. Furthermore, the first table leg 31 and the second table leg 32 are retractable. Specifically, the first table leg 31 includes a first rotating rod rotatably mounted on the first tabletop 21 and a first telescopic rod retractably mounted on the first rotating rod along its extension direction; the second table leg 32 includes a second rotating rod rotatably mounted on the second tabletop 22 and a second telescopic rod retractably mounted on the second rotating rod along its extension direction. This allows it to adapt to frame assemblies 10 of different sizes.

[0065] Please refer to the following: Figure 5 , Figure 6 , Figure 7 and Figure 8 , Figure 6 for Figure 5 A magnified view of the multi-functional vehicle shown at point X; Figure 7 for Figure 5 The image shows a magnified view of the multi-functional vehicle at point Y.

The snap-fit ​​clamp 41 has a snap-fit ​​groove 411, and the locking clamp 42 includes a connecting part 421 for connecting the first tabletop 21, the second tabletop 22, or the third tabletop 23, and a locking part 422 for locking the frame assembly 10. The snap-fit ​​clamp 41 is also equipped with a pivot 43 for rotating the first table leg 31 or the second table leg 32. Optionally, in one embodiment provided in this application, the first tabletop 21 is equipped with two clamp groups 40, wherein the locking clamp 42 is sleeved on the upper frame 11, and the snap-fit ​​clamp 41 is used to snap the lower frame 12. Optionally, in one embodiment provided in this application, the second tabletop 22 is equipped with two second table legs 32 and two corresponding clamps 41, and the third tabletop 23 is equipped with at least two clamps 41, at least two locking clamps 42, or at least one set of clamps 40. At the first tabletop 21, the clamps 41 are used to both fix the first tabletop 21 and install the first table legs 31; at the second tabletop 22, the clamps 41 mainly serve to install the second table legs 32, but can also be used to temporarily fix the second tabletop 22 to the frame assembly 10; at the third tabletop 23, the clamps 41 or locking clamps 42 are used to fix the third tabletop 23 to the upper frame 11.

[0066] Please refer to it again. Figure 2 Optionally, the first tabletop 21 or the second tabletop 22 may also be provided with a first mounting hole 2104 or a second mounting hole 2204. The mounting hole can be used to adapt to cooking equipment such as ovens and saucepans, or it can be customized according to actual functional needs.

[0067] like Figure 1 and Figure 8 As shown, exemplarily, in one embodiment provided in this application, the multifunctional carrier includes two first tabletops 21, two second tabletops 22, and one third tabletop 23. The third tabletop 23 is mounted on the top surface of the frame assembly 10. The two first tabletops 21 are rotatably mounted on both sides of the third tabletop 23. The two second tabletops 22 are detachably mounted on the two first tabletops 21. In the unfolded state, the two first tabletops 21 are flipped upwards and opened. The second tabletops 22 can be selectively spliced ​​and assembled with one of the first tabletops 21, so that the final tabletop is in various shapes such as "I", "L", "T", and "Z". In the cooking scenario, one of the first tabletops 21 and one of the second tabletops 22 are respectively equipped with a first mounting hole 2104 and a second mounting hole 2204, and the first table legs 31 and the second table legs 32 are opened for auxiliary support.
