Best Mode of the Invention

Embodiment 1 As shown in FIG. 1 and FIG. 2, an industrial vehicle may be different types of vehicles, such as a forklift, a stacker, and a sorting truck. This technical solution uses a forklift as an example. Including the main frame 2, the entire vehicle can be roughly divided into two assembly units, where the assembly A includes a handle 32 and a driving wheel assembly 33. Unlike the prior art, the handle 32 is directly connected to the driving wheel assembly 33 instead of connecting via the pumping station bracket or main frame.

The other, the assembly B, includes a main frame 2 to which the pillar 1 is connected. The lifting device 51, the battery box body 4, the pumping station 53, and the controller 52 are all in this assembly B. Specifically, the lifting device 51 may use components such as oil cylinders, and the pumping station 53 is used to supply oil to the lifting device. Both the pumping station 53 and the controller 52 can be fixedly connected to the main frame 2 through a connecting member. One end of the oil cylinder is also connected to the main frame 2 and the other end, that is, one end of the piston rod is in contact with the pillar body 1. With the lifting device, 51 operation, the column 1 and the fork 31 are lifted in the vertical direction.

In this case, as mentioned above, assembly A contains handle 32 and drive wheel assembly 33, while assembly B contains jacking device 51, controller 52, pumping station 53, main frame 2, and pillar For the first-class components, during the steering operation, relative rotation occurs between assembly A and assembly B, but there is no relative rotation between the various components between assembly B.

This design makes the pumping station 53, the controller 52, and the lifting device 51 not as rotating parts, but as stationary parts during steering, less wear and tear, and it is not easy to cause failure or damage. On the other hand, these parts Without turning, it is not easy to cause the risk of pinching to the operator; again, because the pumping station 53, the controller 52, the lifting device 51, and the battery case 4 do not rotate relative to each other, the components are connected to each other. The wires remain relatively still and the wires are not easily broken or damaged.

As shown in FIG. 1, FIG. 2 and FIG. 3, the pillar body 1 includes an upper top plate 11, two side plates 12 and a back plate 13 on both sides, and a cover 15. The upper top plate 11, the side plate 12, the back plate 13, and the cover 15 cooperate with each other to form a receiving space. The jacking device 51, the controller 52 and the pumping station 53 are all installed in this receiving space. Due to the existence of these wrapping components, the lifting device 51, the controller 52 and the pumping station 53 cannot be seen on the outside, and the overall aesthetics of the vehicle is improved.

Different from the prior art, regarding the spatial arrangement of the jacking device 51, the controller 52, and the pumping station 53, this case has been redesigned. As shown in FIG. 2, in the prior art, the controller 52, the jacking device 51, and the pumping station 53 in the figure are originally arranged in a line, and are sequentially arranged from left to right. However, in this case, first, the jacking device 51 is placed on the far right side of the figure, that is, the position closest to the back plate 13, and the controller 52 and the pumping station 53 are located on the same side. These two components are located away from the back plate The position of 13 is the same.

Such a position design has at least two beneficial effects. On the one hand, the jacking device 51 is closer to the back plate 13, that is, there is an abutment contact between the jacking device 51 and the lower surface of the upper top plate 11, and the position of this abutment contact is closer to the back plate 13. Under the leverage effect, the distance between the abutting contact and the back plate 13 is shorter, and the force arm is shorter. The stability of the entire upper top plate 11 is stronger, and the upper top plate 11 is less likely to be lifted to cause tilting or damage. On the other hand, this space arrangement makes the lifting device 51 located in the space surrounded by the upper top plate 11, the side plate 12, and the back plate 13, and the controller 52 and the pump station 53 are placed on the same side and at the same distance, so that The placement method is more compact, the body length of the entire vehicle is shortened, and the turning radius is smaller.

The pillar 1 is also reinforced. As shown in FIGS. 1, 2 and 3, the upper end of the side plate 12 is connected to the upper top plate 11, and the sides of the side plate 12 are connected to the back plate 13. The side plate 12 increases the structural strength of the upper top plate 11 and prevents the upper top plate 11. Deformation and tilt. A back reinforcing plate 16 is provided on the back of the back plate 13, that is, away from the lifting device 51. The side of the reinforced plate 16 is connected to the back plate 13, and the bottom surface is connected to other connecting plates. Support.

For the positional relationship of space, this case has a special design. As shown in Figure 2, two side plates 12 and an upper roof plate 11 form a semi-enclosed space. The lifting device 51, that is, the oil cylinder and the piston rod are installed in this semi-enclosed space. in. It should be particularly pointed out that the semi-enclosed space referred to here refers to the angle of the jacking device 51 viewed from the side of the trolley, located in this semi-enclosed space, that is, from FIG. 2, at an angle facing the screen. Looking at FIG. 2, the side plate 12 partially or completely blocks the jacking device 51.

It should also be noted here that the side plate 12, the back plate 13, and the upper top plate 11 in this case are all part of the pillar body 1 and are load-bearing components, rather than some shells or covers in the prior art. The shell or cover of the prior art is only a covering component and has no bearing effect, which is fundamentally different from the side plate 12, the back plate 13, and the upper top plate 11 in this case.

The jacking principle of the present case is that the cylinder block of the pumping station 53, the controller 52, and the jacking device 51 is connected to the main frame 2 through a connecting member. The pillar 1 is connected to the fork 31, and the pillar 1 is in contact with the piston rod of the jacking device 51. When the piston rod raises the pillar 1, the fork 31 is lifted accordingly.

In this case, the back reinforcing plate 16 has two functions. One is to give structural support to the back of the entire pillar body 1 during the lifting process to increase its stability; the other is to support and fix the support. battery box.

As shown in FIG. 4, FIG. 5 and FIG. 6, the battery box includes a battery box body 4. A handle groove 41 is provided at the upper position for the convenience of a worker's handle. It also extends vertically.

In order to facilitate the installation and slide-in of the battery case 4, a slide-in device is provided. Specifically, a guide rail 17 is provided on the back reinforcing plate 16, and a slide rail groove 44 matching the guide rail 17 is also provided in the retention groove 42, so that the entire battery box can slide in and out more smoothly.

Furthermore, since the worker will hold the battery box in the lowering process, the field of vision will be blocked by the battery box. In order to increase the smoothness and convenience of installation, a guide slope 171 is provided on the guide rail 17, and the battery box box 4 is close to the retention slot Position 42 is correspondingly provided with a sliding slope 43 as shown in FIG. 4. The guide slope 171 and the slide-in slope 43 are both inclined, and the inclination angles are the same, and the slopes cooperate with each other to play the role of slide-in installation guide.

The battery components in the battery box need to be electrically connected to the components on the main frame 2 such as wires or other connectors. Therefore, the battery box box 4 is provided with a connector opening 45, which is also located at the bottom near the retention slot. 42 position.
