Technical Field

[0001] This utility model relates to the field of flatbed vehicle technology, specifically to a telescopic four-wheeled vehicle. Background Technology

[0002] Flatbed trucks are a common type of logistics vehicle, typically used in small-scale logistics transportation. They transport goods by carrying them on their flatbed structure.

[0003] The load-bearing capacity of current flatbed trucks is limited by the surface area of ​​their bodies, and the bodies cannot be adjusted. When the amount of goods to be transported is large, at least two round trips are often required. In addition, flatbed trucks lack limiting structures around them, making it difficult to ensure the stable transport of goods on the vehicle. Utility Model Content

[0004] To address the shortcomings of existing technologies, a telescopic four-wheeled vehicle is proposed, which solves the problems in the background technology where the load-bearing capacity of flatbed vehicles is limited by the surface area of ​​the vehicle body and the vehicle body cannot be adjusted.

[0005] To achieve the above objectives, the present invention proposes the following technologies:

[0006] A telescopic four-wheeled vehicle includes an extension frame located around the periphery of the vehicle body, the distance between the extension frame and the vehicle body being adjustable via a telescopic assembly, and a frame disposed below the vehicle body for connecting wheel assemblies.

[0007] Furthermore, one end of the telescopic component is fixedly connected to the vehicle body, and the other end of the telescopic component is engaged with the extension frame to facilitate adjustment of the distance between the extension frame and the vehicle body.

[0008] Furthermore, the telescopic assembly includes a snap-fit ​​ring, the bottom of which is provided with a first connecting seat for fixing the vehicle body and a second connecting seat for connecting the extension frame.

[0025] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] In this document, terms such as “up,” “down,” “left,” “right,” and “top” indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] like Figures 1 to 6 As shown, a telescopic four-wheeled vehicle includes an extension frame 1 located around the periphery of a vehicle body 2, and the distance between the extension frame 1 and the vehicle body 2 is adjustable via a telescopic assembly. A frame 3 is provided below the vehicle body 2, and the frame 3 is used to connect wheel assemblies.

[0028] By setting an extension frame 1 around the vehicle body 2, the area of ​​the flatbed's load-bearing portion is increased based on the vehicle body 2, thereby greatly increasing the flatbed's capacity. A telescopic component is set to adjust the distance between the extension frame 1 and the vehicle body 2, thereby changing the length of the extension frame 1 extending out of the vehicle body 2 to achieve telescopic adjustment, thus achieving the purpose of adjusting the flatbed's capacity and adjusting the flatbed's load-bearing capacity according to actual needs.

[0029] In this embodiment of the telescopic four-wheeled vehicle, one end of the telescopic component is fixedly connected to the vehicle body 2, and the other end of the telescopic component is engaged with the extension frame 1 to facilitate adjustment of the distance between the extension frame 1 and the vehicle body 2.

[0030] By adjusting the telescopic assembly to engage with the extension frame 1 at different positions, the length of the extension frame 1 extending out of the vehicle body 2 can be adjusted.

[0031] Preferably, the extension frame 1 and the telescopic assembly are detachable. When the extension frame 1 is not required, it can be removed for normal use of the flatbed truck.

[0032] In the telescopic four-wheeled vehicle of this embodiment, the telescopic component includes a snap-fit ​​ring 4, and the bottom of the snap-fit ​​ring 4 is provided with a first connecting seat 5 for fixing and connecting the vehicle body 2, and a second connecting seat 6 for connecting the extension frame 1.

[0033] Specifically, the vehicle body 2 is provided with connecting pipes around its perimeter. The end of the extension frame 1 is inserted into the connecting pipe with an adjustable insertion depth. One end of the snap ring 4 is sleeved on the connecting pipe, and the other end is sleeved on the outside of the extension frame 1. The first connecting seat 5 and the second connecting seat 6 are pressing plates that protrude from the surface of the snap ring 4 and are arranged opposite to each other. The two pressing plates of the second connecting seat 6 tighten the snap ring 4, thereby snapping and fixing the extension frame 1 and limiting its extension length.

[0034] In this embodiment of the telescopic four-wheeled vehicle, the second connecting seat 6 is provided with a locking component for clamping the extension frame 1.

[0035] The locking assembly adjusts the two clamping plates of the second connecting seat 6 to move them closer or further apart, thereby enabling the locking ring 4 to engage or disengage the extension frame 1, facilitating the adjustment of the extension length of the extension frame 1.

[0036] Specifically, the locking assembly includes an adjusting bolt 7 that passes through the second connecting seat 6, and a locking buckle 8 is hinged to the end of the adjusting bolt 7. Rotating the locking buckle 8 can open or tighten the second connecting seat 6.

[0037] The adjusting bolt 7 passes through the two pressure plates. One end of the adjusting bolt 7 is provided with a hinge block that is rotatably connected to the locking buckle 8, and the other end is provided with a limiting structure to prevent it from detaching from the pressure plate. With the above settings, rotating the locking buckle 8 will press the pressure plate sleeved on the adjusting bolt 7, thereby fastening the second connecting seat 6 and limiting the extension frame 1.

[0038] In the telescopic four-wheeled vehicle of this embodiment, the locking buckle 8 includes a handle 9 and a clamping part 10. The handle 9 drives the clamping part 10 to rotate and pushes the second connecting seat 6 to achieve the locking of the extension frame 1.

[0039] Specifically, the locking buckle 8 is L-shaped, and its right angle is rotatably connected to the outside of the hinge block via a pivot. The abutting part 10 is located at its end. By rotating, the abutting part 10 with the protruding shape abuts against the pressure plate at different positions, thereby achieving the pressing or loosening of the two pressure plates and achieving the locking purpose of the locking buckle 8.

[0040] In the telescopic four-wheeled vehicle of this embodiment, the end of the adjusting bolt 7 away from the locking buckle 8 is threaded with an adjusting nut 11. Rotating the adjusting nut 11 causes the adjusting bolt 7 to extend or retract to adjust the tightness of the second connecting seat 6.

[0041] Specifically, the adjusting nut 11 acts as a limiting structure for the adjusting bolt 7. Rotating the adjusting nut 11 causes the adjusting bolt 7 to extend into or out of the adjusting nut 11 through the threaded engagement, thereby changing the extension length of the adjusting bolt 7. Since the other end of the adjusting bolt 7 is limited by the locking buckle 8, the distance between the two clamping plates is further changed, thereby adjusting the clamping degree of the second connecting seat 6 and ensuring the fixing effect of the extension frame 1.

[0042] Preferably, the first connecting seat 5 uses a bolt structure to fix the connecting pipe, so as to achieve the purpose of detachable installation and facilitate the assembly and disassembly of the snap ring 4 and the extension frame 1.

[0043] In this embodiment of the telescopic four-wheeled vehicle, a longitudinal connecting pipe 12 is provided at the front end of the vehicle body 2, and transverse connecting pipes 13 are provided on the left and right sides of the vehicle body 2 respectively. The ends of the longitudinal connecting pipe 12 and the transverse connecting pipe 13 are respectively provided with snap rings 4.

[0044] Specifically, the extension frame 1 is U-shaped and its two ends are respectively inserted into the snap ring 4. Matching it, there are two longitudinal connecting pipes 12 located at the front end, which are symmetrically arranged along the width direction of the vehicle body 2 and are fixedly connected to the vehicle body 2 respectively. Their ends are respectively connected to the two ends of the front extension frame 14 through the snap ring 4. There are two transverse connecting pipes 13, which are fixedly connected to the bottom of the vehicle body 2 and extend along the width direction of the vehicle body 2. The two ends of the transverse connecting pipes 13 extend to the outside of the vehicle body 2 so as to connect to the side extension frame 15 through the snap ring 4.

[0045] Opposite to the front extension frame 14, a mounting base is provided at the rear end of the vehicle body 2, and a pull handle is rotatably connected inside the mounting base.

[0046] Preferably, the front extension frame 14 and the side extension frame 15 each include a horizontal section and an upwardly bent vertical section. The horizontal section is inserted into the snap ring 4 and the connecting tube. With the above arrangement, the vertical section of the extension frame 1 can limit the items carried on the vehicle body 2. In conjunction with the pull handle, it can support and limit the items above the vehicle body 2 from all sides, thereby increasing the capacity while ensuring the stability of the goods during transportation on the vehicle body 2 and reducing the possibility of them falling during transportation.

[0047] Based on the above structure, when the extension frame 1 is not needed, the extension frame 1 can be inserted downwards into the vehicle body 2 for easy storage.

[0048] In the telescopic four-wheeled vehicle of this embodiment, the wheel assembly includes a wheel 16 and an axle 17 for connecting the wheel. The axle 17 is fixedly connected to the lower part of the frame 3. A reinforcing plate 18 is fixedly installed on the frame 3. The axle 17 passes through the reinforcing plate 18 and is fixedly connected to the reinforcing plate 18.

[0049] Specifically, there are two axles 17, located on the front and rear sides of the vehicle body 2 along its length. Each axle 16 is mounted on one end of the axle 17. The axles 17 are fixedly connected to the horizontal parts on the left and right sides of the frame 3. In order to increase the capacity of the vehicle body 2 by extending the frame 1, and to increase the connection strength between the frame 3 and the axles 17 and ensure the load-bearing capacity of large-capacity goods, a reinforcing plate 18 is installed between the frame 3 and the axles 17.

[0050] Preferably, the reinforcing plate 18 is L-shaped, with its top horizontal portion fixedly connected to the frame 3 and its vertical portion fixed to the frame 3 from the outside. The axle 17 passes through the vertical portion and is fixedly connected to the reinforcing plate 18, ensuring the stability of the relative position between the frame 3 and the axle 17, preventing deformation, and thereby increasing the connection strength between the frame 3 and the axle 17.
