Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0041] Figure 1 This is a schematic structural diagram of a truck-mounted forklift according to an embodiment of the present invention, as shown below. Figure 1 As shown, and refer to Figures 2 to 8 This utility model embodiment provides a truck-mounted forklift. The truck-mounted forklift includes a column 100, a platform 200, outrigger assemblies 300, and support assemblies 400.

[0042] The column 100 is installed vertically.

[0043] The platform 200 is set horizontally. The platform 200 is vertically connected to the front side of the column 100.

[0044] The outrigger assembly 300 includes two outriggers 310 and wheels 320 mounted on the outriggers 310. The two outriggers 310 are respectively mounted on the left and right bottom sides of the column 100 and can be pulled back and forth. The wheels 320 are all rolled in the back-and-forth direction.

[0045] The support assembly 400 includes support rods 410, which are retractably and telescopically spaced at the rear side of the column 100 in the vertical direction, so that the support assembly 400 can support the rear side of the column 100. In some embodiments of this utility model, when the trolley is moving normally, the support assembly 400 can be moved to a storage position, and when the support assembly 400 is needed during getting on and off the vehicle, it can be moved to a working position to support the rear side of the column 100.

[0046] The forklift of this invention can climb onto the truck bed 600 or a higher platform using its structure. In the embodiments of this invention, the forklift needs to get on and off the truck as an example.

[0047] During the loading process on the forklift, such as Figure 2 As shown, the platform 200 needs to be raised first, allowing goods to be loaded. After the bottom of the platform 200 is raised to a height higher than the cargo box 600, the accompanying forklift is moved towards the cargo box 600, causing the platform 200 to fall onto the cargo box 600. Figure 3 As shown, the outrigger 310 is then pulled backward, as... Figure 4 As shown, with the support of the support assembly 400 and the platform 200, the column 100 and the outrigger 310 connected to the column 100 are raised. During the process of raising the column 100, the support assembly 400 is always in contact with the ground. After the column 100 and the outrigger 310 are raised to a suitable height, the outrigger 310 is pushed forward onto the truck bed 600, and the support rod 410 is controlled to retract. Finally, the truck-mounted forklift is pushed forward to a suitable position inside the truck bed 600 so that the truck-mounted forklift can complete the loading process.

[0048] During the unloading process of the truck-mounted forklift, the forklift needs to be moved to the edge of the truck bed 600 first, and then the support assembly 400 is lowered so that it contacts the ground. Next, the outriggers 310 are pulled out of the truck bed 600, and the column 100 and the outriggers 310 connected to the column 100 are lowered. After the outriggers 310 contact the ground, they are pushed forward. Then, the entire truck-mounted trolley is moved backward, and the platform 200 is lowered to the ground, thus completing the unloading process of the truck-mounted forklift.

[0049] During the process of the column 100 rising or falling, the platform 200 remains stationary relative to the carriage 600 or the ground. In other words, the distance that the column 100 moves relative to the platform 200 is always consistent with the distance that the telescopic rod extends or retracts.

[0050] In this embodiment, the truck-mounted forklift can directly carry goods into the truck bed 600, eliminating the need for the forklift to lift the goods and then expend effort to horizontally transfer them into the truck bed 600. This avoids the significant manpower and time consumed during the transfer process, achieving rapid loading and unloading while reducing manpower and time consumption. Furthermore, during the ascent or descent of the upright 100 relative to the ground, the support rod 410 directly or indirectly contacts the ground, providing support to the rear of the truck-mounted forklift and preventing it from tipping backward.

[0051] In some embodiments of this utility model, the outer width of the outriggers of the truck-mounted forklift is between 1.5m and 1.8m, the inner width of the outriggers is between 1.1m and 1.7m, and the width of the outriggers is between 0.1m and 0.4m.

[0052] Preferably, in some embodiments of the present invention, the outriggers of the truck-mounted forklift have an outer width of 1.6m and an inner width of 1.3m.

[0053] In this embodiment, due to the large distance between the outriggers, the overall width of the truck-mounted forklift is large, which makes it easier for it to tip over when getting on and off the truck. The support component 400 in this invention can effectively reduce the occurrence of tipping over when the truck-mounted forklift is wide.

[0054] In some embodiments of this utility model, a handrail is provided on the rear side of the column 100.

[0055] In some embodiments of this utility model, a handle is provided on the rear side of the support leg 310.

[0056] In some embodiments of this utility model, the bottom of the vehicle platform 200 is provided with a storage space for storing the support leg 310, so that when the vehicle platform 200 is placed alone on the carriage 600 and the support leg 310 needs to be pushed forward, the vehicle platform 200 and the support leg 310 will not interfere with each other.

[0057] Alternatively, in some embodiments of this utility model, the two support legs 310 are located on both sides of the vehicle platform 200 so that when the vehicle platform 200 is placed alone on the carriage 600 and the support legs 310 need to be pushed forward, the vehicle platform 200 and the support legs 310 do not interfere with each other.

[0058] In some embodiments of this utility model, such as Figure 5 As shown, the support assembly 400 is connected to the support leg 310, and the support assembly 400 also includes a support wheel 420, which is disposed at the bottom of the support rod 410.

[0059] In this embodiment, one end of the support rod 410 is fixedly connected to the outrigger 310, and the other end is fixedly connected to the support wheel 420. When the support assembly 400 supports the rear side of the column 100 of the truck-mounted forklift, that is, when the bottom of the support assembly 400 contacts the ground or other supporting surface, the rolling of the support wheel 420 reduces the friction between the support assembly 400 and the ground during the movement, so that the support assembly 400 can move with the movement of the outrigger 310, making the loading and unloading of the truck-mounted forklift simpler.

[0060] In some embodiments of this utility model, such as Figure 5 As shown, there are two support components 400, with two support rods 410 connected to the rear ends of the two legs 310.

[0061] In this embodiment, the rear sides of both outriggers 310 are connected to support components 400 and are located behind the column 100. The two symmetrically arranged support components 400 can make the forklift more stable during the loading and unloading process.

[0062] In some embodiments of this utility model, such as Figure 6 , Figure 7 and Figure 8 As shown, the support assembly 400 also includes a connecting rod 430, one end of which is rotatably connected to the support leg 310 in the front-back or up-down direction, and the other end is hinged to the support rod 410, so that the support rod 410 can be moved to the center position between the two support legs 310.

[0063] In this embodiment, compared to the embodiment where support components 400 are connected to the rear of both outriggers 310 during the loading and unloading process of the forklift, the number of support components 400 is reduced, resulting in cost reduction. Furthermore, by movably positioning the support rod 410 at the center between the two outriggers 310 to support the rear of the column 100, and since the support components 400 only provide auxiliary support and do not normally require significant support force, a single movable support component 400 not only ensures effective support but also allows the support component 400 to be stored to one side of the outrigger 310 when not needed, reducing the risk of the support component 400 being bumped or knocked.

[0064] In some embodiments of this utility model, the support assembly 400 further includes a first telescopic rod, one end of which is fixedly connected to the support leg 310, and the other end is fixedly connected to the support rod 410. The first telescopic rod can extend and retract in the left-right direction so that the support rod 410 can move to the center position between the two support legs 310.

[0065] In this embodiment, compared to an embodiment where support components 400 are connected to the rear of both outriggers 310 during forklift loading and unloading, the number of support components 400 is reduced, resulting in cost reduction. Furthermore, by movably positioning the support rod 410 at the center between the two outriggers 310 to support the rear of the column 100, and since the support components 400 only provide auxiliary support and do not normally require significant support force, a single movable support component 400 not only ensures effective support but also allows the support component 400 to be retracted to one side of the outrigger 310 when not needed, reducing the risk of impact to the support component 400. Additionally, compared to a rotating support component 400, the left-right telescopic structure is more stable.

[0066] In some embodiments of this utility model, the support rod 410 is fixedly connected to the support leg 310 by a fixing rod that is fixedly connected to the support rod 410 and the support leg 310 at both ends, and the support rod 410 is located at the center position between the two support legs 310.

[0067] In this embodiment, the support structure is more stable than the support rod 410 which can move relative to the support leg 310. However, the support rod 410 cannot be moved after being fixed, which makes it impossible to store the support rod 410. As a result, the support rod 410, which is located in the center between the two support legs 310, is easily bumped.

[0068] In some embodiments of this utility model, the support assembly 400 further includes a second telescopic rod, one end of which is fixedly connected to the column 100 and the other end is fixedly connected to the support rod 410. The second telescopic rod can extend and retract in the front-back direction so that the support assembly 400 can move in the front-back direction.

[0069] In this embodiment, the support rod 410 is connected to the column 100 via a second telescopic rod. The support rod 410 can move independently of the support leg 310, thus making the movement of the support rod 410 more flexible.

[0070] In some embodiments of this utility model, the support rod 410 is a hydraulic lifting rod, and the support assembly 400 further includes a hydraulic drive device for driving the extension and retraction of the hydraulic lifting rod.

[0071] In this embodiment, the hydraulic lifting rod can be used to support a relatively high weight, making its lifting process more stable.

[0072] Alternatively, in some embodiments of this utility model, the support rod 410 may also be a pneumatic telescopic rod.

[0073] In some embodiments of this utility model, the support rod 410 is a lifting screw structure, which includes a lead screw and a turbine. The turbine is threadedly connected to the lead screw. The lifting screw structure is configured to drive the turbine to rotate by turning the handle, thereby driving the lead screw to move.

[0074] In this embodiment, the structure that drives the turbine to rotate by turning the handle, thereby driving the lead screw to move and completing the lifting adjustment function can avoid the use of electricity, thus enabling the truck-mounted forklift to be used in more scenarios, and the fact that it does not use electricity also has the effect of energy saving.

[0075] In some embodiments of this utility model, the vehicle platform 200 is a U-shaped fork.

[0076] In this embodiment, the openings of the U-shaped forks face forward. The U-shaped forks include two forward-facing fork teeth 210. When loading goods onto the truck-mounted forklift, the U-shaped forks can be inserted into the logistics pallet, allowing the goods to be pushed directly away. There is no need to manually move the goods onto the forklift, saving manpower and time.

[0077] In some embodiments of this invention, the thickness at the opening of the U-shaped fork is thinner than the thickness at the connection of the U-shaped fork. When goods need to be loaded, the thinner U-shaped fork at the opening facilitates the insertion of the U-shaped fork under the logistics pallet.

[0078] In some embodiments of this utility model, such as Figure 4 As shown, casters 220 are connected to the platform 200, and the bottom of the casters 220 is lower than the bottom of the platform 200.

[0079] In this embodiment, casters 220 are provided on the platform 200, which provide support for the platform 200. When the platform 200 is alone on the truck bed 600, the position of the forklift can be adjusted without raising the platform 200 to move it away from the truck bed 600.

[0080] In some embodiments of this utility model, the distance between the two fork teeth 210 of the U-shaped fork is adjustable.

[0081] In this embodiment, a telescopic rod is provided between the two fork tines 210. When loading goods is not required, the forklift can adjust the distance between the two fork tines 210 to reduce the distance between them. Reducing the distance between the two fork tines 210 decreases the space occupied by the forklift. Furthermore, the adjustable distance between the two fork tines 210 allows the forklift to be used with more types of logistics pallets.

[0082] In some embodiments of this utility model, such as Figure 2 As shown, the truck-mounted forklift also includes a drive wheel 500, which is located at the bottom of the column 100 and at the center between the two outriggers 310.

[0083] In this embodiment, the drive wheel 500 is connected to the motor and has power. It rotates under the drive of the motor to automatically propel the forklift, saving manpower. Positioning the drive wheel 500 at the center between the two outriggers 310 makes the force on the forklift more even, avoiding the situation where the forklift's walking direction is deviated due to uneven force applied by the drive wheel 500.

[0084] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
