However, the work of applying the resin material for forming the seal member to the through holes of the partition member requires not only simply closing the through holes but also improving the appearance, and requires a skilled technique by hand. There is a problem that the man-hours required for this increase. In particular, as the number of industrial vehicles produced increases, the work of applying the resin material forming the seal member tends to become a bottleneck in the manufacturing process. On the other hand, the cover disclosed in Patent Document 1 is merely a member for preventing electronic parts that do not like water from being exposed to water.

The present invention has been made in view of the above problems, and an object of the present invention is to prevent water from entering the driver's seat through the through hole of the partition member and to be suitable for mass production. Is provided.

In order to solve the above problems, the present invention is an industrial vehicle including a partition member for partitioning a driver's seat and an engine room in a vehicle body, and an electronic device attached to the partition member, in the partition member.

An extending plate member is provided, and the plate member has a flowing water guiding portion that guides water flowing down in the engine room so as to be separated from the through hole.

In the present invention, the plate member is located above the through holes of the electronic device and the partition member attached to the partition member, and extends downward on the opposite side of the driver's seat with the partition member interposed therebetween. Therefore, the water flowing down near the partition member in the engine room is guided in the direction away from the through hole by the flowing water guiding portion of the plate member, and the entry of water into the through hole is prevented. As a result, it is possible to prevent water from entering the driver's seat through the through hole of the partition member. Further, the work of providing the plate member is simpler than the work of applying the resin material for forming the seal member, and the work time is short.

Further, in the above industrial vehicle, the plate member may be fixed to the electronic device.
In this case, by fixing the plate member to the electronic device, the plate member can be attached more easily than when the plate member is fixed to the partition plate.

Further, in the above industrial vehicle, an elastic member may be provided above the plate member between the partition member and the plate member.
In this case, the elastic member interposed in the gap can prevent water from entering the through hole through the gap between the partition member and the plate member. Moreover, since a gap may be provided between the partition member and the plate member at the upper portion of the plate member, the plate member can be provided more easily.

Further, in the above industrial vehicle, the lower portion of the plate member may have a folded-back portion that is folded back upward on the opposite side of the driver's seat.
In this case, the folding back at the lower portion of the plate member can weaken the force of the water flowing through the flowing water guiding portion of the plate member. As a result, water is less likely to splash around, and the electronic device can be protected from water.

Further, in the above industrial vehicle, a plurality of the plate members may be arranged in the width direction of the vehicle body.
In this case, by disposing a plurality of plate members in the width direction of the vehicle body, the plate member can be provided above the partition member where the through hole exists, and the plate member can be provided above the place where the through hole does not exist. It is possible to omit the member. Further, by disposing a plurality of plate members, it is possible to provide the plate members in response to the restrictions on the space in the engine room.

The electronic device 36 is, for example, a timer or a relay. As shown in FIG. 3, the electronic device 36 has a main body 37 and a cover 38 that covers the main body 37. The cover 38 has an inverted U-shaped cross section, and prevents foreign matter such as water and dust from entering the body 37. The body portion 37 and the cover portion 38 are fixed to the plate body 32. Further, the plate body 32 has a large number of through holes. A large number of through holes of the plate body 32 are a through hole 40 for inserting the wiring 39 connected to the electronic device 36 and a through hole 42 for inserting a bolt 41 for fixing the electronic device 36 and the wiring 39. .. These through-holes 40 and 42 are for communicating the driver's seat 12 and the engine room 14, but there are a through-hole and a non-used through hole depending on the specifications of the towing tractor 10. For example, when the specifications of the towing tractor 10 are not the standard specifications but the option specifications to which the optional function is added, since the optional equipment is provided, the through holes 40 and 42 not used in the standard specifications are provided in the wiring 39 and the bolts. May be used for 41.

The towing tractor 10 includes a plate member 45 located above the electronic device 36 and the through holes 40 and 42 in the engine room 14. As shown in FIGS. 2 and 4, a right plate member 45R and a left plate member 45L are arranged in the width direction of the vehicle body 11. The right plate member 45R is located on the right side in the width direction of the vehicle body 11, and the left plate member 45L is located on the left side of the right plate member 45R. As shown in FIGS. 4 and 5, a gap G is provided between the right plate member 45R and the left plate member 45L, and the right bonnet damper 46R for opening and closing the bonnet 15 is located in the gap G. (See Figure 2). The through holes 40 and 42 do not exist below the gap G in the partition member 31. The plate members 45 (45R, 45L) are fastened to the cover portion 38 of the electronic device 36 with bolts 41. In FIG. 2, the bonnet 15 is not shown for convenience of description.

As shown in FIGS. 3 and 5, the plate member 45 (45R, 45L) includes a lower plate portion 47 (47R, 47L) located in the front portion of the electronic device 36 and a top plate member from the upper end of the lower plate portion 47. 33 has an upper plate portion 48 (48R, 48L) extending below the front portion. Plural through holes 49 (49R, 49L) for inserting bolts are formed in the lower plate portion 47. The lower end of the lower plate portion 47 has substantially the same height as the lower end of the cover portion 38. The lower plate portion 47 has an inclination angle along the front portion of the cover portion 38, and the upper plate portion 48 is substantially parallel to the top plate body 33 of the partition member 31. A sponge member 50 as an elastic member is interposed between the upper plate portion 48 and the top plate body 33.

The sponge member 50 is provided as a waterproof dam that prevents water flowing down to the engine room 14 from flowing into the partition member 31. By elastically deforming the sponge member 50, an operator can assemble the plate member 45 to the electronic device 36 without being aware of the clearance between the upper plate portion 48 and the top plate body 33 when the plate member 45 is assembled.

The plate surfaces of the lower plate portion 47 and the upper plate portion 48 on the engine room 14 side correspond to the flowing water guiding portion. The flowing water guiding portion guides the water flowing down to the engine room 14 so as to separate the water from the holes 40 and 42. At the lower end of the plate member 45, a folded back 51 (51R, 51L) that is folded back toward the front is formed. The folding back 51 has a function of improving the strength of the plate member 45 and a function of reducing the flow velocity of water flowing through the plate surfaces of the lower plate portion 47 and the upper plate portion 48 on the engine room 14 side.

As shown in FIGS. 4 and 5, the folding back 51 of the right plate member 45R is formed in the width direction of the lower end. The folding back 51 of the left plate member 45L is formed only on a part of the lower end. The left plate member 45L is provided with a first notch 52 into which the left bonnet damper 46L is inserted, extending from the upper plate portion 48 to the upper portion of the lower plate portion 47. Further, the left plate member 45L is formed with a second cutout 54 for avoiding interference with the brake booster 53 provided in the engine room 14. In the partition member 31, the through holes 40 and 42 do not exist below the first cutout 52 and the second cutout 54.

Next, the operation of the towing tractor 10 according to this embodiment will be described. When precipitation occurs on the towing tractor 10 as in the case of rainy weather, for example, water flowing along the front window 21 reaches the top plate body 33 of the partition member 31. The water reaching the top plate 33 further enters the engine room 14 and flows down along the plate surface of the plate member 45 on the engine room 14 side. In FIG. 3, the flow of water is shown by a white arrow. Since the upper plate portion 48 of the plate member 45 has an inclined surface with a gentler slope than the lower plate portion 47, part of the water reaching the top plate body 33 goes backward depending on the amount of water, but by the sponge member 50. Ingress of water to the rear is blocked.

The water flowing down along the plate surface on the engine room 14 side, which is the flowing water guiding portion of the plate member 45, has an increasing flow velocity as it goes downward, but the flow velocity decreases due to collision with the turnback 51. The water that has collided with the folding back 51 flows forward of the folding back 51, flows in the width direction along the folding back 51, and flows down from the end portion of the folding back 51 in the width direction. Therefore, the water flowing down the plate member 45 is guided in a direction away from the through holes 40 and 42 of the partition member 31, does not reach the through holes 40 and 42, and reaches the driver's seat 12 through the through holes 40 and 42. No water will enter.

The towing tractor 10 of this embodiment has the following effects.
(1) The plate member 45 is located above the electronic device 36 attached to the partition member 31 and the through holes 40 and 42 of the partition member 31, and faces the lower side opposite to the driver's seat 12 with the partition member 31 interposed therebetween. Extend. Therefore, the water flowing down near the partition member 31 in the engine room 14 is guided in the direction away from the through holes 40 and 42 by the flowing water guiding portion of the plate member 45, and the water flowing into the through holes 40 and 42 is discharged. Entry is blocked. As a result, it is possible to prevent water from entering the driver's seat 12 through the through holes 40 and 42 of the partition member 31. Further, the work of providing the plate member 45 is simpler than the work of applying the fluid resin material forming the seal member, and can be completed in a short time.

(2) By fixing the plate member 45 to the electronic device 36, the plate member 45 can be attached more easily than when the plate member 45 is fixed to the partition member 31.

(3) At the upper part of the plate member 45, the sponge member 50 as an elastic member is interposed between the top plate body 33 of the partition member 31 and the upper plate portion 48 of the plate member 45. Therefore, since a gap may be provided between the top plate body 33 of the partition member 31 and the upper plate portion 48 of the plate member 45, the plate member 45 can be provided more easily. Further, the sponge member 50 interposed in the gap can prevent water from entering the through holes 40 and 42 through the gap between the partition member 31 and the plate member 45. Further, since the elastic member is the sponge member 50, for example, the material cost is lower than that in the case where a weather strip is provided, the number of assembling operations can be reduced, and sheet metal working is not necessary. Therefore, by using the sponge member 50 as the elastic member, the manufacturing cost can be suppressed.

(4) The lower portion of the plate member 45 has the folded back portion 51 that is folded back upward on the opposite side of the driver's seat 12. Therefore, the folding back 51 at the lower portion of the plate member 45 can weaken the force of the water flowing through the flowing water guiding portion of the plate member 45. As a result, water is less likely to splash around the plate member 45, and the electronic device 36 can be protected from water.

(5) A plurality of plate members 45 (45R, 45L) are arranged in the width direction of the vehicle body 11. Therefore, by disposing the plurality of plate members 45 in the width direction of the vehicle body 11, the plate member 45 can be provided above the place where the through holes 40 and 42 exist in the partition member 31, and the through hole 40 can be provided. It is possible to prevent the plate member 45 from being provided above the portion where the electrodes 42 and 42 do not exist. Further, by disposing the plurality of plate members 45, it is possible to provide the plate members corresponding to the restriction of the space in the engine room 14.

(6) By providing the first cutout 52 in the left plate member 45L, it is possible to avoid interference with the left bonnet damper 46L, and at the position where the left plate member 45L overlaps the left bonnet damper 46L. The left plate member 45L can be provided in the width direction without division. Further, by providing the second cutout 54, it is possible to avoid interference between the brake booster 53, which is a device arranged in the engine room 14, and the left plate member 45L.

(Second embodiment)
Next, a towing tractor according to the second embodiment will be described. In the towing tractor of this embodiment, the configuration of the plate member is different from that of the first embodiment. In the present embodiment, the description of the first embodiment is cited for the same configuration as the first embodiment, and common reference numerals are used.

As shown in FIG. 6, the plate member 61 included in the towing tractor 60 of the present embodiment includes a rear extension portion 62 that further extends from the rear end of the upper plate portion 48. The rear extension portion 62 has an inclined surface having a greater slope than the upper plate portion 48. Therefore, the plate member 61 makes it difficult for water to enter rearward from the upper plate portion 48. Further, since the rearward extension portion 62 is formed, the strength of the plate member 61 is further improved.

The towing tractor 60 of the present embodiment has the same effects as the effects (1), (2), (4) to (6) of the first embodiment. Further, by providing the rearward extension portion 62, it is possible to prevent water from entering the rearward side without using the sponge member 50. The strength can be improved. In FIG. 6, the flow of water is shown by an outline arrow.

The present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the invention, and for example, the following modifications may be made.

In the above embodiment, the plate member is fixed to the electronic device, but the present invention is not limited to this. The plate member may be fixed to the partition plate, for example, and in this case, the cover portion of the electronic device can be omitted. The fixing destination of the plate member is not particularly limited.
In the above-described embodiment, the sponge member as the elastic member is interposed between the partition member and the plate member above the plate member, but the elastic member is not limited to the sponge member. The elastic member may be a member that can be elastically deformed without deforming the plate member and the partition plate, such as rubber rubber.
In the above-described embodiment, the lower portion of the plate member has the folded portion that is folded back to the upper side on the opposite side of the driver's seat, but this is not a limitation. The folding back is not an indispensable structure, and a plate member without folding back may be used.
In the above embodiment, the plurality of plate members are arranged in the width direction of the vehicle body, but the present invention is not limited to this. A single plate member may be provided in the width direction of the vehicle body. Further, when a plurality of plate members are arranged in the width direction of the vehicle body, the number of plate members is not limited to two, and three or more plate members may be arranged.
In the above embodiment, an example of a towing tractor as an industrial vehicle has been described, but the industrial vehicle is not limited to a towing tractor.
