[0024] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0025] Example 1 A multi-mode warehouse vehicle, such as Figure 2 As shown, it includes a main body 10, a handle 20, a connecting part 30, and an auxiliary part 40.

[0026] Among them, the main stem 10 is the load-bearing foundation and structural skeleton of this utility model. For example... Figure 3 As shown, the main frame 10 includes a main frame 101, a support plate is fixed to the main frame 101, and a shovel plate 12 is hinged to the bottom end of the main frame 101, thus forming the support platform of this utility model. Main wheel seats 102 are fixed to both sides of the lower part of the main frame 101, and the main wheel seats 102 are connected to a main wheel axle 105. Main wheels 13 are fixed to both sides of the main wheel axle 105. Auxiliary fixing members 103 are also fixed to both sides of the lower part of the main frame 101. The auxiliary fixing members 103 are located inside the main wheel seats 102, and the two cooperate to connect to the auxiliary structural tube 401 of the auxiliary part 40. Movable tube connectors 104 are fixed to both sides of the upper part of the main frame 101 to connect to the movable tube 402 of the auxiliary part 40. In addition, several strap buckles 107 are fixed to the sides of the main frame 101, which can be used to fix the goods to the loading platform with straps or ropes, which is beneficial for transporting irregularly shaped goods.

[0027] The connecting part 30 is fixed to the top of the main body 10 and is a mechanism component that enables multi-angle adjustment of the main body 10 and the handle part 20. Specifically, the two connecting seats 306 of the connecting part 30 are bolted to the main frame 101 of the main body 10, and a movable seat 307 is movably connected to the outside of the connecting part 30. The movable seat 307 is bolted to the pusher frame tube 201 of the handle part 20. Figure 5 and Figure 6 The connecting part 30 shown has a connecting locking structure fixed inside. This connecting locking structure is an innovation of this utility model. It includes a hollow locking tube 301, with double-headed locking rods 305 arranged on both sides inside the locking tube. The double-headed locking rods 305 can move along the length of the locking tube 301. A locking spring 303 is arranged between the two double-headed locking rods 305. A locking rod movable hole is provided at one end of the double-headed locking rod 305 near the locking spring 303, and a double-column locking head is provided at the other end near the movable seat 307. A locking switch 302 is fitted in the middle of the outside of the locking tube. The locking tube 301 is provided with a radial tube movable groove, and the locking switch 302 is provided with an inclined switch movable groove. The locking rod movable hole, the tube movable groove, and the switch movable groove are all fitted with a fixing pin 304. In its natural state, the locking spring 303 located between the two double-headed locking rods 305 is in a contracted state. The elastic force of the locking spring 303 forces the double-headed locking rods 305 to protrude from the locking tube 301. At this time, the double-column locking heads of the double-headed locking rods 305 are engaged in the locking holes of the movable seat 307, thereby fixing the connection angle between the movable seat 307 and the connecting seat 306, that is, fixing the setting angle of the main body 10 and the handle part 20.

[0028] Handle section 20 Figure 4 As shown, the upper part of the pusher frame tube 201 of the handle part 20 is fitted with a retractable handle structure. The handle structure includes a handle part 202 and a handle locking part 203 that are locked with tenons and mortises. An upper handle part 207 is fixed above the handle part 202, and a handle torsion spring 206 is provided between the two. The handle locking part 203 is movably fitted onto the lower handle part 205 below, and a handle spring 204 is provided between the two. In the natural state, the handle spring 204 is in a contracted state, and its elastic force drives the handle locking part 203 to abut against the handle part 202. At this time, the tenon of the handle part 202 is engaged into the mortise of the handle locking part 203, thereby realizing the locking of the handle part 202 in the folded / unfolded state.

[0029] The auxiliary part 40 is a structure that assists the load-bearing platform in supporting the cargo, and it is also the key to realizing the inclined loading and four-wheeled loading of this utility model. Figure 7As shown, it includes an auxiliary structure tube 401 and its secondary wheel seat 403, a positioning kit 406, a movable kit 406 connected to a movable tube 402, and an auxiliary locking structure fixed between the two movable kits. The auxiliary locking structure includes a hollow locking tube 301, a locking switch 302, a locking spring 303, a fixing pin 304, and a single-headed locking rod 405. (Reference) Figure 8 In its natural state, the locking spring 303 located between the two single-headed locking rods 405 is in a contracted state. The elastic force of the locking spring 303 forces the single-headed locking rod 405 to protrude from the locking tube 301. At this time, the single-column locking head of the single-headed locking rod 405 is engaged in the lock hole of the auxiliary structure tube 401, thereby fixing the connection position between the movable tube 402 and the auxiliary structure tube 401, that is, fixing the folded / unfolded state of the auxiliary part.

[0030] It should be further explained that locking holes are provided on the inner sides of both the upper and lower parts of the pusher frame tube 201. When the auxiliary locking mechanism is locked in the upper part, the movable tube 402 is perpendicular to the pusher frame tube 201, and the auxiliary part 40 is in the unfolded state. When the auxiliary locking mechanism is locked in the lower part, the movable tube 402 is parallel to the pusher frame tube 201, and the auxiliary part 40 is in the folded state. In addition, the auxiliary locking structure of the auxiliary part 40 and the connecting locking structure of the connecting part 30 have the same working principle and basically the same structural components. The difference is that the auxiliary locking structure uses a single-headed locking rod 405, which passes through the movable kit 406 and locks the pusher frame tube 201. The connecting locking structure 305 uses a double-headed locking rod, which passes through the connecting seat 306 and locks the movable seat 307.

[0031] Furthermore, a fixing handle 410 is fixed to the auxiliary structure tube 401 of the auxiliary part 40. The fixing handle 410 includes a fixing handle shell, a fixing switch 411 is provided in the fixing handle shell, and a fixing spring 413 is provided between the two. Inclined switch movable grooves are provided on both sides of the fixing switch 411, and the switch movable grooves are connected to a fixing locking rod 412. The fixing locking rod is restricted by the fixing handle shell and can only move along the length direction. In the natural state, the elastic force of the fixing spring 413 in the contracted state forces the fixing switch 411 to protrude from the fixing handle shell, thereby causing the fixing locking rod 412 to protrude from the fixing handle shell. The support plate 11 of the main body 10 is provided with a locking hole that matches the fixing locking rod 412. Therefore, the auxiliary part 40 can fix the fixing handle 410 to the support plate 11, thereby preventing the auxiliary part 40 from falling off when it is in the folded state. In addition, the main frame 101 of the main body 10 is also fixed with two fixing clips 106, which can hold the auxiliary structure tube 401 of the auxiliary part 40 to enhance the stability of the equipment when the auxiliary part is folded.

[0032] Example 2 Based on the multi-mode warehouse vehicle disclosed in Embodiment 1, it has three working modes: a two-wheeled warehouse vehicle, an inclined-load handcart, and a four-wheeled flatbed vehicle, as well as a folding mode for easy storage and transportation. The conversion process between the three modes is as follows: Figure 1 As shown, the details are as follows: Folding mode to four-wheeled flatbed truck: Workers place the cargo truck in its folded-down mode horizontally on the ground, with both the main wheels and casters in contact with the ground. The operator folds the shovel up from its folded state until it is perpendicular to the support plate. Then, the operator presses the locking switch of the connecting locking structure. The double-headed locking rod retracts into the locking tube to release the locking of the movable seat, i.e., releases the locking of the handle. The operator rotates the handle away from the support plate until it is perpendicular to the main body, i.e., the angle between the handle and the main body rotates from 0 degrees to 90 degrees. At this point, the double-headed locking rod, under the elastic force of the locking spring, engages with the locking hole at the 90-degree position of the movable seat, locking the handle back into its fixed position. Simultaneously, the handle locking piece is pulled down, disengaging the handle. Under the elastic force of the torsion spring, the handle pops out from its folded state. The released handle locking piece, under the elastic force of the handle spring, abuts against the handle and locks it again to secure the handle in its unfolded state. This constitutes the four-wheeled flatbed truck of this utility model.

[0033] Four-wheeled flatbed trailers are suitable for open spaces, transporting large / multiple items, and long-distance transport. Both the main wheels and casters are in contact with the ground, and the platform is horizontal, providing good load-bearing capacity. Workers only need to push or pull to move the device, without bearing the weight of the goods, making it suitable for long-distance transport. However, four-wheeled flatbed trailers are generally wide and long, making them difficult to maneuver in confined spaces, and manual loading and unloading is required.

[0034] From four-wheeled flatbed trucks to two-wheeled cargo trucks: Workers place the four-wheeled flatbed cart, which is horizontally positioned on the ground, vertically onto the ground, with only the main wheels of the cart in contact with the ground. Workers then press the locking switch of the connecting locking mechanism again to release the handle, and rotate the handle until it is parallel to the main frame again, that is, the angle between the handle and the main frame rotates from 90 degrees to 180 degrees. At this point, the handle is locked back into its fixed position, thus forming the two-wheeled cargo cart of this utility model.

[0035] Two-wheeled flatbed trucks are suitable for transporting small items and short distances in narrow spaces. Their relatively small width and length allow them to easily navigate confined areas, making them quite flexible. Workers can use the shovel to load and unload goods, which is convenient. However, the shovel is the primary load-bearing structure of a two-wheeled flatbed truck, limiting its capacity to small items. Furthermore, the truck's balance relies on manual labor; if the cargo is too large or heavy, it can shift the truck's center of gravity, increasing the workload and posing safety risks.

[0036] From two-wheeled cargo vans to inclined-load handcarts: The operator presses the fixing switch of the auxiliary part fixing handle to release the lock between the auxiliary part and the support plate, and at the same time presses the locking switch of the auxiliary locking structure to release the lock of the movable kit. The movable kit is then pulled from the lower part of the pusher frame tube to the upper part and locked again, that is, the movable tube, which was parallel to the pusher frame tube, is adjusted to be perpendicular to the pusher frame tube. The operator tilts the cargo truck until the main wheels and the universal wheels of the auxiliary part simultaneously contact the ground, thus forming the inclined loading cargo truck of this utility model.

[0037] Compared to two-wheeled warehouse trucks, inclined-load handcarts have better load-bearing capacity because all four wheels are in contact with the ground simultaneously and an auxiliary part bears the weight. Compared to four-wheeled flatbed trucks, inclined-load handcarts are smaller in overall width and length, enabling them to operate in confined spaces and thus offering greater flexibility. However, inclined-load handcarts are less flexible than two-wheeled warehouse trucks and have lower load-bearing capacity than four-wheeled flatbed trucks.

[0038] There are no "absolute advantages" or "absolute disadvantages" among the three working modes. The key is that the mode conversion can meet the transportation needs of multiple scenarios such as warehousing, workshop, and distribution, and solve the problem of poor adaptability of traditional equipment.

[0039] In summary, the connection locking structure and auxiliary locking structure of this utility model enable switching between three working modes: two-wheeled cargo cart, inclined handcart, and four-wheeled flatbed cart. This adapts to various scenarios such as warehousing, workshops, and distribution, effectively solving the problem of poor adaptability of traditional transportation equipment. Furthermore, the shovel, handle structure, and auxiliary parts of this utility model are all foldable, allowing the device to be folded into a stowed mode when not in use, thus avoiding the occupation of excessive storage space.

[0040] The above embodiments are not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model are also within the protection scope of the present utility model.
