Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a side panel structure of an industrial vehicle, and particularly to a side panel having a step portion, which is an industry intended to avoid splash intrusion from around the step when the panel is closed. The present invention relates to a vehicle side panel structure.

(Prior Art) Among industrial vehicles, an electric one, for example, an electric forklift uses a motor as a power source, and a plurality of motors are provided for traveling and hydraulics. For example, a hydraulic motor is provided at a position where it can be easily inspected in the vehicle body, and the motor brush is inspected by opening a side panel that also serves as a motor chamber cover. An electric forklift truck of this type generally has a high seat position and requires a step portion on the side surface of the vehicle body on which a foot can be placed to facilitate getting in and out, and the step portion is often provided on the side panel.

10 to 14 are views showing a side panel structure of a conventional industrial vehicle. In FIG. 10, the side panel 1 is attached to the side surface of the industrial vehicle 2 so as to be openable and closable, and the side panel 1 has steps. A section 3 is provided. In addition,
Reference numeral 4 is, for example, a hydraulic motor. 11 to 14 are detailed views of the side panel 1 and a part of the vehicle body to which the side panel 1 is attached. In these drawings, 5 is a side frame on the vehicle body side, and the side frame 5 includes a battery plate 6, a lower panel 7, and these battery plates 6
And two panels provided between the lower panel 7, namely the first panel 8 and the second panel 9, and
The panel 8 is formed with a notch 8a for escaping the step portion 3. Reference numeral 10 denotes a rod with which the hook 11 of the side panel 1 is engaged, a spacer 12 is attached to the side panel 1, and a rubber 13 is bonded to the plate end of the first panel 8 ( (See Figure 12).

In such a configuration, the side panel 1 can be opened with the engagement point between the hook 11 and the rod 10 as a fulcrum, and inspection of the motor 4 (friction inspection and replacement of the motor brush) can be facilitated. Further, when the side panel 1 is closed, it is possible to get on and off while stepping on the step portion 3.

(Problems to be Solved by the Invention) However, in such a conventional side panel structure for an industrial vehicle, the side panel 1 provided with the step portion 3 closes the opening (that is, the motor chamber) of the side frame 5. Therefore, the plate end shape of the first panel 8 becomes complicated including the notch 8a, and therefore, there is a slight gap between the side panel 1 and the first panel 8 in consideration of variations at the time of opening and closing. A gap (α) (see Figure 14) had to be provided.

For this reason, if a splash of muddy water or the like is generated from the wheels during traveling, the splash easily enters the motor chamber through the gap, which causes a problem in terms of environmental resistance of the motor 4. In addition, as a measure against this problem, rubber has been traditionally used.
Although the rubber 13 is provided, the rubber 13 is easily damaged by the interference from the step portion 3 when the side frame 1 is opened / closed or getting on / off, and it is difficult to maintain a good sealing state for a long time.

Therefore, the present invention has an object to stably avoid splash intrusion into the motor chamber when the panel is closed for a long period of time.

(Means for Solving the Problem) In order to achieve the above object, a side panel structure for an industrial vehicle according to the present invention is a side panel which doubles as a door of a motor chamber provided in a vehicle body and which can be opened and closed with a lower end as a fulcrum. A step portion formed by recessing a member fixed to the panel in a box shape toward the motor chamber, a first panel forming one side wall of the motor chamber, and an outer surface of the first panel when the side panel is closed. A support protector of a predetermined shape that is erected on the inner surface of the side panel along the vehicle body, and a surface that is attached to the vehicle body and that can contact the edge of the support protector when the side panel is closed. And a seal rubber attached to at least one of an edge of the support protector and an abutting surface of the plate panel. The edge portion of the heat protector has a shape along a straight line connecting the surface of the step portion on the inner side of the vehicle body and the lower end of the side panel.

(Operation) In the present invention, since the seal rubber is not located on the lower surface side of the step portion, it is less likely to be interfered with by the step portion when opening / closing the side panel or getting on / off the side panel. Therefore, the deterioration of the seal rubber is prevented, and the invasion of the splash is kept stable for a long period of time.

(Example) Hereinafter, the present invention will be described with reference to the drawings.

1 to 7 are views showing a first embodiment of a side panel structure for an industrial vehicle according to the present invention, which is an example applied to an electric forklift.

In FIG. 1, reference numeral 20 denotes a side panel. The side panel 20 is provided with a step portion 21 and a hook 22 on which a foot can be placed, and a support protector 23 is attached. The support protector 23 is attached to a surface 20a of the side panel 20 on the inner side of the vehicle body in an upright state, and an edge portion of the support protector 23 is bent to form a contact surface 23a. Here, the contact surface 23 of the support protector 23
As shown in FIG. 4, the extension of a is substantially the same as the one surface 21a which is the surface of the step portion 21 on the inner side of the vehicle body. The support protector 23 is made of two plates (fourth and fifth plates).
(See the figure), which facilitates the production, but it goes without saying that it may be made of a single plate.

On the other hand, 24 is a side frame on the vehicle body side, and the side frame 24 includes a battery plate 25, a lower panel 26, and a first panel 27 and a second panel 28 provided between the battery plate 25 and the lower panel 26, respectively. A plate panel that has and is supported by the first panel 27
29 and the plate panel 29 have a seal rubber 30 bonded to one surface 29a. Here, the edge portion (contact surface 23a) of the support protector 23 is shown in FIG. 1, FIG. 3, and FIG.
As is clear from FIG. 5 or FIG. 5, the step portion 21 has a shape along a straight line connecting the inward surface of the vehicle body (one surface 21a) and the lower end of the side panel 20. The shape of one surface 29a of the panel 29 is formed so as to be substantially the same as the surface shape formed by the contact surface 23a of the support protector 23 and the one surface 21a of the step portion 21. In addition, 31 is a notch and 32 is a rod.

In such a structure, as shown in FIG. 3, when the side panel 20 is closed, the contact surface 23 of the support protector 23 is closed.
The one surface 21a of the a and the step portion 21 and the one surface 29a of the plate panel 29 are in close contact with each other via the seal rubber 30. Therefore, it is possible to prevent the splash from entering the motor chamber, and since the seal rubber 30 is not located on the lower surface side of the step portion 21, the side panel
It is difficult to receive interference from the step portion 21 when opening and closing the 20 or getting on and off, and it is possible to stably avoid the intrusion of the splash for a long period of time. Further, since the support protector 23 is fixed to the inner surface of the side panel 20 by welding, for example, the side panel 20 can be reinforced. Further, since the airtightness of the motor chamber is improved, the operating noise of the motor can be shielded and the quietness can be improved.

In the above embodiment, the plate panel 29 is attached to the first panel 27.
Although the example in which the seal rubber 30 is adhered to the plate panel 29 is shown, the present invention is not limited to this. For example, as shown in the second embodiment in FIGS.
The plate edge of is suitable shape (preferably the same shape as 29a above)
Then, the seal rubber 41 may be adhered to the plate end.

Although the seal rubber is attached only to the side frame side (vehicle body side) in the first and second embodiments, it may be attached to both the side frame side and the side panel side, or only the side panel side. May be attached to.

(Effect) According to the present invention, it is possible to stably avoid splash intrusion into the motor chamber when the panel is closed for a long period of time.
