Description

Technical Field

[0001] This utility model relates to a folding handcart with a table, which is particularly suitable for outdoor self-driving, picnic, camping and other scenarios. It can serve both the function of carrying items and temporary storage, solving the problem of adapting to small space storage and multiple scenarios. It belongs to the field of handcart technology. Background Technology

[0002] As residents' quality of life improves, self-driving outdoor activities (such as picnics and camping) have become a mainstream leisure activity, requiring users to carry various items such as food, cooking utensils, and tents. Limited by the distance between parking spots and activity areas, items often need to be carried on foot. Among existing solutions, folding trolleys are widely used because they can be stored in the trunk of a car. However, current folding trolleys on the market still have the following technical shortcomings, making it difficult to meet users' needs for efficient and convenient use:

[0003] Folding is cumbersome and storage is inefficient: Most existing handcarts have a one-way or two-way folding structure, which requires multiple operations such as unlocking the buckles and pushing the brackets. They also lack a convenient lifting and positioning structure. Folding takes a long time for a single person (usually 1-2 minutes), and the folding operation is even more inconvenient when carrying items outdoors with one hand.

[0004] Even after folding, the volume remains too large, resulting in poor space utilization: Most products still retain a "thick plate" or "long strip" structure after folding, making it impossible to further reduce the horizontal or vertical dimensions. They are prone to interfering with other items in the trunk of a car (especially small cars), and lack storage flexibility; They have limited functionality and weak adaptability to different scenarios: Existing handcarts only have the single function of "carrying". In outdoor scenarios, users need to temporarily place items such as plates, ingredients, and tools, requiring the additional carrying of a folding table, which increases the weight of the equipment and storage costs;

[0005] Insufficient load-bearing stability: Some products have a single-layer pole structure at the bottom without reinforced support design. When bearing heavy objects of more than 15kg (such as bottled water or folding chairs), the support is prone to deformation and swaying, which may even affect the safety of movement.

[0006] Based on the shortcomings of the existing technologies, there is an urgent need for a handcart that combines "easy folding, small size storage, functional integration, and strong load-bearing capacity" to solve the pain points of use in outdoor scenarios. Utility Model Content

[0007] This utility model proposes a folding trolley with a table, which aims to achieve "one-click lifting and folding" to improve storage efficiency, integrate the table to expand functions, and strengthen the support structure to enhance load-bearing capacity, meet the needs of outdoor use in multiple scenarios, and solve the problems of existing folding trolleys such as cumbersome folding operation, large storage volume, single function, and insufficient load-bearing stability.

[0008] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0009] A folding handcart with a table includes a bottom support assembly, a front U-shaped frame and a rear U-shaped frame hinged to the bottom support assembly. The bottom support assembly includes a first lower U-shaped frame and a second lower U-shaped frame. The inner retractable rods of the first lower U-shaped frame and the second lower U-shaped frame are hinged to each other, allowing the two U-shaped frames to be brought closer together or unfolded.

[0010] The first lower U-shaped frame is hinged to the front U-shaped frame, and the second lower U-shaped frame is hinged to the rear U-shaped frame.

[0011] The lower ends of the vertical frames of the front and rear U-shaped frames are connected to casters, allowing for easy pushing and pulling in all directions. These casters feature rubber anti-slip surfaces and can rotate 360°, making them suitable for uneven surfaces such as outdoor grass and gravel roads.

[0012] A scissor-type folding structure is provided between the front U-shaped frame and the rear U-shaped frame.

[0013] The rear U-shaped frame is connected to a tabletop via a support plate and a folding assembly;

[0014] The folding assembly includes a first folding piece and a second folding piece connected by a pivot. The first folding piece is hinged to the tabletop, and the second folding piece is hinged to the vertical frame of the rear U-shaped frame. A support plate is used to support the load of the tabletop. The tabletop can rotate around the hinge point of the first folding piece, and when folded, it fits against the vertical frame of the rear U-shaped frame. When unfolded, it is parallel to the horizontal plane and its position is locked by the pivot of the folding assembly.

[0015] The front U-shaped frame is hinged to a handle via a hinged seat.

[0016] The scissor-type folding structure includes a first diagonal bar, a second diagonal bar, a third diagonal bar, and a fourth diagonal bar;

[0017] The top end of the first diagonal rod is hinged to the vertical frame of the rear U-shaped frame, and the tail end is hinged to the top end of the second diagonal rod.

[0018] The tail end of the second diagonal rod is hinged to the vertical frame of the front U-shaped frame, and the middle end is hinged to the middle end of the third diagonal rod.

[0019] The top end of the third inclined rod is hinged to the tail end of the fourth inclined rod, and the tail end is hinged to the vertical frame of the rear U-shaped frame.

[0020] The top of the fourth diagonal rod is hinged to the vertical frame of the front U-shaped frame. The scissor structure can synchronously link the front and rear U-shaped frames to close / open, and after opening, it is automatically limited by the friction of the rod hinge points to prevent the frame from swaying.

[0021] The first lower U-shaped frame and the second lower U-shaped frame are both supported by support frames between their transverse frames. This is to enhance the transverse support strength of the bottom support and prevent the frame from deforming when bearing heavy objects.

[0022] The top of the horizontal frame of the first lower U-shaped frame is provided with an additional connecting piece, and the additional connecting piece is provided with a rope for the user to lift and fold the trolley, so that the user can lift it to trigger the folding action.

[0023] This utility model has the following advantages and beneficial effects:

[0024] The folding handcart with a table involved in this utility model has the following four advantages:

[0025] 1. Significantly improved folding convenience and storage efficiency: Through the synergistic design of "additional connecting piece + rope" and "scissor folding structure", users only need to pull the rope upwards (single-step operation, time ≤10 seconds) to drive the first and second lower U-shaped frames to close together and the front and rear U-shaped frames to retract, achieving "one-click folding"; the overall volume after folding is reduced by more than 35% compared with existing similar products (taking the unfolded size of 120cm×60cm×80cm as an example, the folded size is only 60cm×30cm×25cm), which can be easily stored in the corner of a small car trunk, avoiding interference with other items.

[0026] 2. Enhanced functionality and significantly improved scene adaptability: The integrated foldable tabletop eliminates the need for additional outdoor tableware. When unfolded, the tabletop covers an area of ​​40cm x 60cm, providing stable support for plates, cooking utensils, food, and other items (with a load capacity of ≥10kg), meeting the needs for outdoor picnic storage. When folded, the tabletop forms a U-shaped frame that does not occupy the space required for trolley transport, enabling a dual function of "transportation + storage" and reducing the user's equipment load.

[0027] 3. Significantly improved load-bearing stability and durability: The first and second lower U-shaped frames of the bottom bracket are equipped with horizontal support frames, which, together with the hinged reinforcement structure of the inward-retracting rod, can effectively distribute the pressure of heavy objects and prevent the bracket from deforming; the scissor-folding structure forms a "triangular stable support" after unfolding, and with the rubber anti-slip casters, the trolley does not wobble when carrying a 30kg load (the load-bearing stability is improved by 50% compared to the structure without support frames), and the casters have a high wear resistance coefficient, making them suitable for complex outdoor terrain and extending the product's service life.

[0028] 4. Operational flexibility to meet the needs of multiple users: The rotatable handle can be adjusted to the grip angle (0°-30°) according to the user's height (1.5m-1.9m), avoiding bending over to push and pull; the 360° swivel wheel design allows for flexible turning even in narrow outdoor paths (width ≤80cm), solving the problem of "stuck turning" in existing handcarts.

Detailed Implementation

[0034] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0035] Reference Figures 1-3 A folding handcart with a table includes a bottom support assembly, a front U-shaped frame 2 and a rear U-shaped frame 4 hinged to the bottom support assembly. The bottom support assembly includes a first lower U-shaped frame 8 and a second lower U-shaped frame 12. The inner retractable rods 17 of the first lower U-shaped frame 8 and the second lower U-shaped frame 12 are hinged to each other, which can realize the relative closeness / expansion of the two U-shaped frames. The design of the inner retractable rods 17 makes it convenient for the bottom support assembly to be wide on both sides and narrow on the inside, so as to maximize the size of the handcart.

[0036] The first lower U-shaped frame 8 is hinged to the front U-shaped frame 2, and the second lower U-shaped frame 12 is hinged to the rear U-shaped frame 4.

[0037] The lower ends of the vertical frames of the front U-shaped frame 2 and the rear U-shaped frame 4 are connected to casters 7, which allow users to easily push and pull them in all directions for convenient use. The casters 7 have rubber anti-slip surfaces and can achieve 360° rotation, making them suitable for uneven surfaces such as outdoor grass and gravel roads.

[0038] A scissor-type folding structure is provided between the front U-shaped frame 2 and the rear U-shaped frame 4. The rear U-shaped frame 4 is connected to a tabletop 5 via a support plate 18 and a folding assembly 6. The folding assembly 6 includes a first folding piece and a second folding piece connected by a pivot. The first folding piece is hinged to the tabletop 5, and the second folding piece is hinged to the vertical frame of the rear U-shaped frame 4. The support plate 18 is used to support the load-bearing capacity of the tabletop 5. The tabletop 5 can rotate around the hinge point of the first folding piece. When folded, it fits against the vertical frame of the rear U-shaped frame 4. When unfolded, it is parallel to the horizontal plane and its position is locked by the pivot of the folding assembly 6.

[0039] The front U-shaped frame 2 is hinged to a handle 1 via a hinge seat 9.

[0040] The scissor-type folding structure includes a first inclined rod 13, a second inclined rod 14, a third inclined rod 15, and a fourth inclined rod 16. The top end of the first inclined rod 13 is hinged to the vertical frame of the rear U-shaped frame 4, and its tail end is hinged to the top end of the second inclined rod 14. The tail end of the second inclined rod 14 is hinged to the vertical frame of the front U-shaped frame 2, and its middle end is hinged to the middle end of the third inclined rod 15. The top end of the third inclined rod 15 is hinged to the tail end of the fourth inclined rod 16, and its tail end is hinged to the vertical frame of the rear U-shaped frame 4. The top end of the fourth inclined rod 16 is hinged to the vertical frame of the front U-shaped frame 2. The scissor-type structure allows for the synchronous closing / unfolding of the front and rear U-shaped frames, and after unfolding, the frictional force at the hinge points of the rods automatically limits the movement, preventing the frame from swaying.

[0041] Support frames 10 are provided between the transverse frames of the first lower U-shaped frame 8 and the second lower U-shaped frame 12 for support. This enhances the lateral support strength of the bottom support and prevents deformation of the frame when bearing heavy objects. An additional connecting piece 11 is provided at the top of the transverse frames of the first lower U-shaped frame 8. The additional connecting piece 11 has a rope for the user to pull and fold the trolley, allowing the user to trigger the folding action. The trolley also has a cloth cover 3.

[0042] Folding operation procedure:

[0043] Unlock tabletop 5: Push tabletop 5 upward around the hinge point between the first folding piece and tabletop 5 to separate tabletop 5 from support plate 18. Continue to rotate until tabletop 5 is in contact with the vertical frame of U-shaped frame 4. At this time, the pivot of folding component 6 locks the position of tabletop 5 through friction to prevent shaking.

[0044] Overall folding: The user pulls the rope on the additional connecting piece 11 upwards with one hand. The first lower U-shaped frame 8 and the second lower U-shaped frame 12 move closer to each other around the hinge point of the inner retracting rod 17. At the same time, the front U-shaped frame 2 and the rear U-shaped frame 4 drive the scissor folding structure (first diagonal rod 13, second diagonal rod 14, third diagonal rod 15, and fourth diagonal rod 16) to retract around each hinge point. The front U-shaped frame 2 and the rear U-shaped frame 4 gradually move closer until the overall size after folding reaches 60cm×30cm×25cm, and the folding is completed.

[0045] Storage and securing: After folding, the frame can be secured with ropes to prevent it from falling apart during transportation.

[0046] Expand the operation process:

[0047] Unlock the frame: Untie the ropes and pull the front U-shaped frame 2 and the rear U-shaped frame 4 with both hands respectively. The scissor-type folding structure unfolds gradually. The first lower U-shaped frame 8 and the second lower U-shaped frame 12 separate around the hinge point of the inner retracting rod 17 until the bottom support is fully unfolded. The rod of the scissor-type structure is automatically limited by the friction of the hinge point to ensure the stability of the frame.

[0048] Unfold tabletop 5: Push tabletop 5 downward around the hinge point of the first folding piece until the bottom surface of tabletop 5 is fully in contact with the support plate 18. At this time, tabletop 5 is parallel to the horizontal plane, and the pivot of folding component 6 locks the position of tabletop 5, thus completing the unfolding of tabletop 5.

[0049] Adjust handle 1: Depending on the user's height, rotate handle 1 around the hinge seat 9 to adjust to a comfortable angle (e.g., 15°) to push the trolley to move items, or use the table 5 for temporary storage.

[0050] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
