The front side of the frame 12 has an embedding groove 120 extending vertically, and the inner mast 2 is embedded in the embedding groove 120 of the frame of the outer mast. In addition, the hydraulic cylinder 5 is installed on the base 11 and is coaxial with the inner mast 2. The hydraulic cylinder 5 is used for the relative lifting and lowering of the inner mast 2 and the outer mast 1. Such a design effectively improves the stability and safety of the relative lifting and lowering of the inner mast and the outer mast. Specifically, the hydraulic cylinder 5 includes a cylinder body and a piston rod. The top end of the piston rod is connected to the top end of the inner mast 2. The entire cylinder and the piston rod are embedded in the inner mast 2. The hydraulic cylinder 5 is connected to the hydraulic station 6 through a hydraulic hose to realize the driving of the hydraulic cylinder. The specific structure of the hydraulic cylinder and the hydraulic station can refer to the prior art and will not be repeated here.

[0032] A driving wheel 9 is installed in the middle of the base 11 for bearing weight and driving the forklift. In addition, balance wheels 10 are installed on the left and right sides of the base 11 for assisting in bearing weight and balancing the forklift body to prevent the forklift from tipping over.

[0033] The fork frame 3 of this embodiment is fixedly installed on the front side of the inner mast 2 and is used to carry goods. In this embodiment, the fork frame 3 is lifted and lowered by the inner mast 2 and the outer mast 1, so as to realize the lifting and lowering of the fork frame 3, which effectively solves the defects of instability and insecurity of directly driving the lifting and lowering of the fork frame 3 by the screw rod. Specifically, the fork frame 3 includes a vertical fixing seat 31 and two horizontal leg forks 32 extending forward on its left and right sides. The vertical fixing seat 31 is fixed to the bottom of the front side of the inner mast 2 by bolts or screws, and the horizontal leg fork 32 has a accommodating cavity 320 for pushing the ground movable leg 4.

[0034] The two movable legs 4 of this embodiment are movably connected to the left and right sides of the outer mast base, respectively, to push and pull with the outer mast 1; when the movable legs 4 are pushed into the front side of the outer mast 1, the movable legs 4 are inserted into the accommodating chamber 320 of the horizontal leg fork of the fork frame; when the movable legs 4 are pulled out of the rear side of the outer mast 1, the movable legs 4 and the fork frame 3 are respectively located at the front and rear sides of the outer mast 1; such a design enables the vehicle-mounted forklift to automatically enter the truck compartment with good stability. Among them, the front end of the movable legs 4 is equipped with a load-bearing wheel 13 for bearing weight; the middle part of the movable legs 4 is provided with a guide wheel group 14 for guiding and supporting when the movable legs 4 are pushed and pulled; the rear end of the movable legs 4 is provided with a push-pull handle 40 for easy pushing and pulling of the movable legs 4.

[0035] A control handle 8 is provided above the base 11 of the outer door frame of this embodiment. The control handle 8 is located above the driving wheel 9 and extends upward to control the movement and lifting of the forklift. Specifically, the control handle 8 includes a handle bar and a handle head connected to the top thereof, and is also provided with a lifting button, a lowering button, a forward knob, a backward knob, a power meter, a horn, an accelerator, a keyhole, etc., wherein the forward knob and the backward knob are located on both sides of the handle head, and the remaining buttons are located on the handle bar or the handle head. The specific structure of the control handle can refer to the prior art and will not be described here. A detachable protective cover 15 is provided between the bottom of the control handle 8 and the base 11, such as being fixed and installed by bolts or screws to achieve detachability.

[0036] The left side space of the base 11 of this embodiment is used to install the power supply battery 7. A left cover 16 is set corresponding to the power supply battery 7. The top of the left cover 16 is hinged with a flip cover 160 to facilitate the extraction of the power supply battery; the right side space of the base 11 is used to install the hydraulic station 6. A right cover 17 is set corresponding to the hydraulic station 6. The tops of the right cover 17, the left cover 16 and the detachable protective cover 15 are flush. Among them, the rear side of the base 11 is set with a driving protective cover 18 corresponding to the driving wheel 9 to prevent the driving wheel from being exposed; the above cover has dustproof and waterproof and heat dissipation functions, is made of metal, is not easy to be damaged and is strong and durable. In addition, an emergency switch 19 is set on the top of the base 11 to realize the emergency braking of the forklift; a protective cover plate 20 is set corresponding to the emergency switch 19. The protective cover plate 20 is flush with the tops of the right cover 17, the left cover 16 and the detachable protective cover 15, and the protective cover plate 20 is fixed and installed by a plum handle bolt. The split design of the above cover can be realized by separate disassembly and assembly, which is convenient for maintenance.

[0037] The right cover 17 of this embodiment is also provided with function buttons 22, such as a forward knob, a reverse knob, a mode button, etc. When the forklift enters the truck compartment, the forward and reverse movements of the forklift can be controlled by the function buttons 22 at the bottom of the forklift. When the mode button is pressed, the forward knob and the reverse knob can be activated to control the forward and reverse movements of the forklift inside the truck.

[0038] like Figure 5 As shown, the workflow of the truck-mounted forklift of this embodiment includes the following steps:

[0039] Step 1: The forklift's forklift carries the goods. The forklift approaches the truck compartment and lifts the goods.

[0040] Step 2: After the cargo is lifted slightly above the platform of the truck compartment, operate the forklift to move into the truck compartment;

[0041] Step 3: Lower the forklift so that the cargo falls to the rear end of the carriage platform, and then the forklift moves back so that the cargo is at the front end of the forklift.

[0042] Step 4. Slightly lift the forklift and operate the forklift to move the goods into the truck compartment.

[0043] Step 5. Lower the forklift to the platform of the carriage, slightly lift the outer frame off the ground, and pull out the two movable legs.

[0044] Step 6. Lift the outer mast until the upper plane of the ground-moving legs does not exceed the height of the cargo insertion position, that is, below the cargo, and the fork frame insertion position is higher than the ground-moving legs landing height, so as to push the ground-moving legs in;

[0045] Step 7. Push the movable legs to the fork frame. At this time, the load-bearing wheels and guide wheel assembly are located inside the carriage platform.

[0046] Step 8. Slightly lift the fork frame so that it leaves the carriage platform and does not touch the top position under the cargo;

[0047] Step 9. After pushing the driving wheel to the edge of the carriage, start the forklift and drive it into the carriage until the rear end of the fork frame approaches the cargo to a suitable position;

[0048] Step 10. Slightly lift the fork frame to make it leave the carriage platform and move forward to the appropriate position;

[0049] Step 11. Lower the fork frame so that it lands on the carriage platform and park the forklift.

[0050] The truck-mounted forklift of this embodiment is electrically driven for lifting and traveling, and is labor-saving to operate; the vehicle is compact and has a self-lifting function, so the entire vehicle can enter or exit a truck by itself, and can follow the truck and assist the operator in loading and unloading goods.
