Description

Technical Field

[0001] This utility model relates to the field of trolleys, specifically a new type of folding handcart. Background Technology

[0002] As people's living standards improve, they often carry various items when traveling or shopping. However, backpacks generally have limited capacity and cannot meet the needs of travelers. To improve their carrying capacity and accommodate more items, all kinds of handcarts have emerged.

[0003] The advent of handcarts has made it convenient for users to carry items when out and about. Early handcarts lacked folding functionality, taking up considerable storage space after use and making them inconvenient to store. To address this, numerous folding handcarts have emerged, not only meeting users' needs for moving items but also simplifying storage after use. Therefore, folding handcarts, with their portability, durability, and ease of storage, are highly favored for outdoor activities.

[0004] Currently, folding handcarts are typically folded up and stored aside after transporting goods. Furthermore, most folding carts have a cross-shaped base, which limits their load-bearing capacity and ability to carry items.

[0005] Patent No. 2024103635838 discloses a heavy-duty handcart. Although it solves the load-bearing problem, it remains idle when folded and stored and cannot be used again, thus failing to make the most of the material. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a new type of folding handcart, which has a novel design, reasonable structure, multiple functions, and strong load-bearing capacity. After folding, it can be folded into the shape of a rectangular table or rectangular stool, which can meet the various needs of users, facilitate users to reuse it, and make the most of the material.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] This utility model includes a vehicle frame, a foldable base plate rotatably connected to the vehicle frame, and wheels fixedly disposed below the vehicle frame. The vehicle frame includes a front assembly, a rear assembly, and a folding assembly disposed between the front assembly and the rear assembly. The front assembly includes a front support member, uprights fixedly disposed at both ends of the front support member, and a handle fixedly disposed at the top of the uprights. The rear assembly includes a rear support member, uprights fixed at both ends to the rear support member via bases, and a stop bracket rotatably connected to the rear support member via bases. The two ends of the folding assembly are respectively connected to the uprights of the front assembly and the rear assembly. The folding assembly is two or more sets of X-shaped assemblies connected end to end. The top of the folding assembly is fixed to the uprights via a fixed part, and the bottom slides up and down along the uprights via a movable part to realize the folding assembly. The components are unfolded and folded; the base plate includes a joint and brackets rotatably connected to the joint at both ends. The length of the brackets is the same as the height of the columns, and the thickness of the joint is the same as the thickness of the support rod. The joint is U-shaped, and the connection end of the bracket to the joint is located in the U-shaped groove of the joint. When the bracket is rotated to a vertical position, it lifts the U-shaped groove to achieve folding of the base plate. When the bracket is rotated to a horizontal position, it supports the joint to achieve unfolding of the base plate. The bracket is connected to the joint through fulcrums on both sides of the joint. The bracket includes a crossbar connected to the fulcrum, a connecting rod between the two crossbars, and a support rod between the two connecting rods. The crossbar includes a first crossbar and a second crossbar. The other end of the first crossbar is connected to the columns on both sides, and the other end of the second crossbar is connected to the columns through a base.

[0009] A further improvement of this utility model is that: the fulcrum includes a first fulcrum connected to the first crossbar and a second fulcrum connected to the second crossbar, the first crossbar being connected to the connector through the first fulcrum, and the second crossbar being connected to the connector through the second fulcrum.

[0010] A further improvement of this utility model is that the wheel includes a front wheel and a rear wheel, the front wheel with a brake is symmetrically arranged on the front support member, and the rear wheel is symmetrically arranged at the end of the rear support member.

[0011] A further improvement of this utility model is that the baffle is fixed to the column by a clamp that is fixedly set on the column.

[0012] A further improvement of this utility model is that the vehicle frame is provided with a push handle whose length and height are adjustable.

[0013] A further improvement of this utility model is that the push handle is rotatably connected to the middle of the front support member.

[0014] The beneficial effects achieved by this utility model due to the adoption of the above technical solution are as follows:

[0015] This utility model features a novel design and a reasonable structure. It not only fulfills the function of a handcart carrying heavy objects, but also, when folded, the handcart, together with its base, can form a rectangular table or stool with a flat top, making it convenient for outdoor users to place items or for users to sit on. Moreover, the height of the folded handcart is the same as the height of the folded base, meaning that the height and width of the folded handcart are no higher than those of the unfolded handcart, only the length is smaller. Therefore, it does not require much space during storage, achieving the effect of making the most of the material. Attached Figure Description

[0024] The present invention will be further described in detail below with reference to embodiments:

[0025] A new type of folding handcart, such as Figure 1-7 As shown, it includes a vehicle frame, a rotatably connected and folded bottom plate, and wheels located below the vehicle frame. The vehicle frame and the bottom plate work together to form a box for holding goods, which facilitates the transportation of goods. The wheels transport the box along with the goods inside the box.

[0026] like Figure 1 As shown, the vehicle frame includes a front assembly, a rear assembly, and a folding assembly 7 disposed between the front assembly and the rear assembly. The front assembly includes a front support member 11, uprights 10 fixedly disposed at both ends of the front support member 11, and a handle 5 disposed at the top of the uprights 10. The rear assembly includes a rear support member 13, uprights 10 fixed to the rear support member 13 at both ends via bases 12, and a baffle 14 movably connected to the rear support member 13 via bases 12. The baffle 14 is fixed to the uprights 10 via clamps 9 fixedly disposed on the uprights 10. The baffle 14 and clamps 9 can be configured to be fixed together or separated from the baffle 14 depending on the length of the object being transported. When the object being transported is long and the container is insufficient to hold it, the baffle 14 can be separated from the clamps 9, allowing the baffle 14 to rotate around the base 12 to a state parallel to the bottom plate. Figure 1 and Figure 2 The state shown allows the transported item to be placed on the plane formed by the base plate and the baffle 14, which facilitates the transport of longer objects. When the length of the transported object does not exceed the length of the base plate, the baffle 14 can be clamped onto the clamp 9 to form a closed box structure.

[0027] Under the action of external force, the folding component 7 folds inward, causing the front and rear components to move inward simultaneously, while the movable part 8 moves downward along the column 10. The length of the trolley continuously decreases, achieving the folding of the trolley frame. Figure 4 and Figure 5 The folded state facilitates storage; the folding component 7 passively unfolds outwards, and as the front and rear components move further away from the folding trolley and its length gradually increases, the movable part 8 moves upwards along the column 10, thus unfolding the trolley frame. Figure 1 and Figure 2 Its unfolded state facilitates the transport of goods.

[0028] like Figures 1-3 As shown, the folding assembly 7 is disposed on both sides of the vehicle frame. Both ends of the folding assembly 7 are connected to the columns 10 of the front and rear assemblies, respectively. The folding assembly 7 consists of two or more X-shaped components connected end-to-end. The top of the folding assembly 7 is fixed to the column 10 via a fixing part 6, and the bottom slides up and down along the column 10 via a movable part 8, thus enabling the folding assembly 7 to unfold and fold. Under the action of external force, as the movable part 8 moves down along the column 10, the X-shaped components continuously move down and fold together, achieving the convergence and folding of the folding assembly 7, until... Figure 4 and Figure 5The trolley is designed for easy storage. During the folding process, the X-component continuously moves downwards, so the height of the trolley does not increase after folding. Similarly, there is no folding structure in the width direction of the trolley during the folding process, so the width remains unchanged. As the movable part 8 moves upwards along the column 10, the X-component moves upwards accordingly, gradually being pulled apart to allow the folding component 7 to unfold, until it is as described above. Figure 1 and Figure 2 The state is designed to facilitate the transportation and storage of items.

[0029] like Figure 6 and Figure 7 As shown, the base plate includes a connector 3 and brackets rotatably connected to both ends of the connector 3. The length of the brackets is the same as the height of the column 10, and the thickness of the connector 3 is the same as the thickness of the handle 5. This design ensures that the handcart can be folded up as shown. Figure 4 and Figure 5 The rectangular shape shown is convenient for use as tables and chairs after goods have been transported while traveling, ensuring that the items are not left idle. This provides the most thoughtful service for travelers, meets various user needs, and achieves the best use of resources.

[0030] The connector 3 is U-shaped, and the connection end of the connector 3 to the bracket is located in the U-shaped groove of the connector 3. When the bracket is rotated to a vertical position, the U-shaped groove is lifted to achieve the folding of the base plate. Figure 7 The top surface is flat, and the sides are rectangular right prisms, such as a rectangular table or stool. The support is rotated to a horizontal position, and the three joints at both ends are used to unfold the base plate into the shape shown. Figure 6 The horizontal position is used to place goods.

[0031] like Figure 6 and Figure 7 As shown, the bracket includes a crossbar 1-3 connected to a fulcrum, a connecting rod 1-1 positioned between two crossbars 1-3, and a support rod 1-2 positioned between two connecting rods 1-1. The crossbar 1-3 is connected to a joint 3 via a first fulcrum 3-1 and a second fulcrum 3-2. The crossbar 1-3 rotates around a pivot point located at the connection points 1-1 and 3-2, allowing for easy folding and unfolding of the base plate. The crossbar 1-3, connecting rod 1-1, and support rod 1-2 facilitate the bearing of heavy objects. To meet the need for heavy loads, the number of support rods 1-2 can be increased, or additional support rods 1-2 can be added between the two joints 3. Therefore, the base plate is sturdy and durable, with good load-bearing capacity, and can reliably bear heavy objects without the need for a support plate.

[0032] The crossbars 1-3 include a first crossbar 1 and a second crossbar 2. The other end of the first crossbar 1 is connected to the uprights 10 on both sides, and the other end of the second crossbar 2 is connected to the uprights 10 on both sides via a base 12. Lifting the connector 3 upwards causes the first crossbar 1 and the second crossbar 2 to simultaneously pull the uprights 10 connected to them on both sides inwards, and the folding assembly 7 moves downwards to complete the folding of the trolley. Figure 4 and Figure 5 As shown, to facilitate the reuse of the folded cart, a sturdy canvas bag can be used to cover the folding cart and secure it firmly to prevent it from unfolding outwards under gravity during use and causing an accident. When the cart needs to be used to transport objects, as the uprights 10 are pulled outwards from both sides, the connector 3 moves downwards under the action of the first crossbar 1 and the second crossbar 2. At the same time, the folding assembly 7 gradually unfolds as the movable part 8 moves upwards along the uprights 10 until the folding assembly 7 is fully unfolded. Figure 1 and Figure 2 As shown.

[0033] The bracket is connected to the connector 3 via fulcrums on both sides of the connector 3. Each fulcrum includes a first fulcrum 3-1 connected to the first crossbar 1 and a second fulcrum 3-2 connected to the second crossbar 2. The first crossbar 1 is connected to the connector 3 via the first fulcrum 3-1, and the second crossbar 2 is connected to the connector 3 via the second fulcrum 3-2. A pivot is provided at the connection points of the first fulcrum 3-1 and the first crossbar 1, and at the connection points of the second fulcrum 3-2 and the second crossbar 2. Rotating the pivots allows the first crossbar 1 and the second crossbar 2 to rotate. When the first crossbar 1 and the second crossbar 2 rotate to a certain position... Figure 6 When in the horizontal position shown, the joint 3 is supported from both sides to unfold the base plate; when the first crossbar 1 and the second crossbar 2 rotate to the position shown... Figure 7 In the vertical position shown, the joint 3 is lifted from both ends to achieve the folding of the base plate.

[0034] like Figures 1-5 As shown, the wheels include front wheels and rear wheels. The front wheels are symmetrically arranged on the front support member 11, and the front wheels are equipped with brakes 15 for braking. The rear wheels are symmetrically arranged at the ends of the rear support member 13. This arrangement ensures that when the trolley is folded up, the four wheels are firmly supported on the ground like four outriggers. The brakes 15 prevent the trolley from starting, whether it is moving or folded; the trolley can only move smoothly by releasing the brakes 15.

[0035] The vehicle frame is equipped with a push handle 4 whose length and height are adjustable. The push handle 4 is rotatably connected to the middle of the front support member 11. During the pushing process, the length and height of the push handle 4 can be adjusted in real time as needed to facilitate smooth pushing of the vehicle.

[0036] In summary, when unfolded, this trolley functions like any other trolley for transporting and holding items. Its biggest improvement lies in its folded state, ensuring it remains usable even when not idle. The trolley can be folded into a rectangular table or bench for convenient use by travelers. Furthermore, the height and width of the folded trolley do not increase, minimizing storage space requirements.

[0037] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are by no means intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description; it is impossible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom still fall within the protection scope of this invention.
