[0018] In order to illustrate the technical scheme of the utility model, the following will be explained by specific embodiments.

[0019] For the convenience of illustration, only parts related to the embodiments of the utility model are shown.

[0020] Combined Figures 1-3 As shown in the figure, the electric stacker truck comprises a vehicle body 1, two walking wheels 2 are arranged at the bottom of the vehicle body 1, a pair of moving bottom plates 3 are arranged at the front bottom of the vehicle body 1, a stacking mechanism is arranged on the moving bottom plate 3, a partition plate 5 is arranged in the vehicle body 1, the partition plate 5 divides the vehicle body into two sections, a driving mechanism for driving the walking wheels 2 is arranged in the front section, a control assembly 6 is arranged in the rear section, a pair of fixed plates 7 are arranged in the vehicle body 1, a pair of slide rods 8 are arranged on the fixed plates 7, a top seat 9 is arranged at the top of the two pairs of slide rods 8, a pair of battery assemblies 10 are arranged on the top seat 9, the driving mechanism comprises a bearing seat 81 which is slidably arranged on the slide rod 8, the walking wheels 2 are arranged on the outer side of the bearing seat 81, a driving motor 11 for driving the walking wheels 2 is arranged on the inner side of the bearing seat 81, a guide rod 12 is arranged at the top of the bearing seat 81, the top of the guide rod 12 penetrates through the top seat 9, and a buffer spring 13 is arranged on the guide rod 12.

[0021] In the field of logistics storage, the electric stacker truck is an indispensable key equipment for cargo handling and stacking operation. The electric stacker truck comprises a vehicle body, a pair of walking wheels is arranged below the vehicle body, a pair of moving bottom plates is arranged at the front side of the vehicle body, each moving bottom plate 3 is rotatably arranged downwardly with a roller 31, and a stacking mechanism is arranged on the moving bottom plate. A partition plate is arranged in the vehicle body, the partition plate divides the vehicle body into two sections, a driving mechanism is arranged in the front section, and a control assembly is arranged in the rear section, and the two sections are arranged to make the whole structure more reasonable.

[0022] As Figure 4 shown, the stacking mechanism comprises a fixed frame 14, a lifting screw rod 15 is rotatably arranged at the middle of the fixed frame 14, a sliding plate 16 is arranged at the front side of the fixed frame 14, a threaded seat 161 is arranged at the back of the sliding plate, the lifting screw rod is arranged in the threaded seat, a fork 17 is arranged on the sliding plate 16 and faces two moving bottom plates 3, a driven gear 18 is arranged at the bottom of the lifting screw rod 15, a lifting motor 19 is arranged in the vehicle body 1, a driving shaft of the lifting motor 19 is provided with a driving gear 20, and the driving gear 20 is meshingly installed with the driven gear 18.

[0023] As Figure 1 shown, a plurality of control buttons 22 are arranged on the top plate of the vehicle body 1, and the control buttons are electrically connected with the driving motor and the lifting motor through the control assembly. The control buttons control the work of the left and right driving motors and the lifting motor through the control assembly. The control assembly is prior art, so it is not described here.

[0024] In the diagram, the forks include a pair of stacking arms, which are located directly above the moving base plate. When the electric stacker is used to stack the goods, the traveling wheels are first driven by the driving mechanism until the electric stacker moves to the stacking position. Then the operator starts the lifting motor through the control button on the top plate of the vehicle body, and the driving shaft of the lifting motor drives the driving gear to rotate, and the lifting screw rod rotates under the linkage of the driven gear. The rotation of the lifting screw rod drives the sliding plate to move up and down along the fixed frame, thereby realizing the lifting of the forks and completing the stacking and carrying operation of the goods.

[0025] In the above stacking process, when the electric stacker is ready to start running, the operator is in place, and the forward movement instruction is sent by pressing the corresponding control button. The signal is transmitted to the driving mechanism of the front partition, and the driving motor starts to drive the same traveling wheels to rotate, thereby realizing the movement of the vehicle. During the driving process, if uneven ground is encountered, the vibration of the traveling wheels will be transmitted to the bearing seat, and the bearing seat will slide up and down on the sliding rod with a small amplitude, and the influence of the vibration on the vehicle body and the goods can be reduced under the action of the buffer spring, thereby ensuring the stability of the vehicle driving.

[0026] As a preferred structure, as Figure 3 The battery assembly 10 includes a pair of C-shaped positioning frames 101 installed on the top seat, and a battery box 102 is placed in the C-shaped positioning frames 101. A pair of pull handles 103 are arranged on the battery box 102. A door 104 is arranged on the top plate of the vehicle body 1 opposite to the battery assembly 10, and a rotating handle 105 is arranged on the door.

[0027] When the batteries in the battery box need to be maintained, the operator first opens the door, then unplugs all the connectors on the battery box, and finally holds the pull handle to take out the battery box from the C-shaped positioning frame for replacement or maintenance. After the maintenance is completed, the battery box is placed back into the C-shaped positioning frame, and the door is closed.

[0028] The above only describes the preferred embodiments of the present application, and is not intended to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principles of the present application shall be included in the protection scope of the present application.
