Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a structure for mounting a rear lamp unit on a forklift truck, and more particularly to a structure for protecting the rear lamp unit from mud splash and splash caused by rotation of wheels.
[0002]
[Prior art]
In a general forklift truck, a rear weight is occupied by a counterweight, so that a rear lamp unit (rear combination lamp) is mounted directly on the counterweight.
[0003]
For example, as disclosed in Japanese Utility Model Application Laid-Open No. 59-92046, a lamp housing recess is formed from the rear surface of the counterweight toward the front, and a rear lamp unit is housed and arranged in the lamp housing recess. The inner part of the lamp housing recess directly opens into the wheel house.
[0004]
[Problems to be solved by the invention]
In the conventional structure as described above, it is inevitable that mud or splash scattered due to the rotation of the wheel enters the lamp housing recess, thereby causing rust of the mounting bracket and the mounting bolt as well as the metal part of the rear lamp unit. Invitation and improvement in durability cannot be expected.
[0005]
In particular, if the lamp socket, the mounting bracket, or the mounting bolts are rusted, it will not be possible to replace each individual component, such as the bulb, and eventually the entire rear lamp unit, including the mounting brackets and mounting bolts, must be replaced. This has the disadvantage of increasing repair costs.
[0006]
The present invention has been made in view of the above problems, and in particular, protects the rear lamp unit and its attached parts from rusting by preventing intrusion of mud and splash into the lamp accommodating recess, and thereby, the rear lamp unit. It is an object of the present invention to provide a structure that improves the durability of the surroundings and reduces the repair cost.
[0007]
[Means for Solving the Problems]
According to the first aspect of the present invention, there is provided a lamp having a lamp receiving recess having a vertical partition wall at a rear portion thereof on a rear surface of a counterweight, and a lamp mounting wall portion parallel to the partition wall with respect to the lamp receiving recess. The rear lamp unit is accommodated and arranged via a bracket, and a harness insertion hole for inserting a wire harness connected to the rear lamp unit is separately formed in the partition and the lamp mounting wall of the lamp bracket. The position of the harness insertion hole formed in the part and the lamp mounting wall part is offset from each other.
[0008]
The invention described in claim 2 is characterized in that the positions of both harness insertion holes in the invention described in claim 1 are offset from each other in a two-dimensional direction of a height direction and a vehicle width direction.
[0009]
According to a third aspect of the present invention, the lamp bracket according to the second aspect has a lamp mounting wall portion and a leg portion extending rearward from the lamp mounting wall portion to have a substantially L-shaped cross section. Further, the leg piece is bolted to the inner lower surface of the lamp receiving recess.
[0010]
According to a fourth aspect of the present invention, the rear lamp unit according to the third aspect of the invention is elongated in the vehicle width direction, and a lamp mounting wall portion of the lamp bracket is formed by bolts penetrating both ends in the longitudinal direction of the rear lamp unit. And each harness insertion hole is located at the center of the span formed by the bolts.
[0011]
According to a fifth aspect of the present invention, the partition wall and the lamp mounting wall of the lamp bracket according to any one of the first to fourth aspects are surfaces facing each other and the opening of each harness insertion hole. At a position corresponding to the edge, a splash guard is formed so as to protrude toward the mating surface.
[0012]
Therefore, according to the first and second aspects of the present invention, the lamp housing recess formed in the counterweight and the wheel house are separated by the partition, and they are communicated only through the harness insertion hole formed in the partition. As a result, the mud and splash scattered by the rotation of the wheels from the wheel house side to the lamp housing recess side are extremely unlikely to enter, protecting the rear lamp unit, lamp bracket and mounting bolts from rusting. can do.
[0013]
This difficulty in infiltration of mud and splash is further promoted by the fact that the harness insertion holes formed separately in the partition wall and the lamp mounting wall are offset from each other. Even if the splash penetrates, it can hardly penetrate further into the rear side of the rear lamp unit through the harness insertion hole of the lamp mounting wall.
[0014]
In particular, according to the third aspect of the present invention, since the leg portion of the lamp bracket having a substantially L-shaped cross section extends rearward and the leg portion is bolted to the inner and lower surfaces of the lamp accommodating concave portion, the bracket is separated from the partition wall portion. By securing the distance to the mounting bolt as large as possible, it becomes possible to further protect the bracket mounting bolt from adhesion of mud or splash.
[0015]
For the same reason, in the invention according to claim 4, the mounting bolt of the lamp unit is offset with respect to the harness insertion hole of the partition wall, and the distance from the harness insertion hole of the partition wall becomes longer, so that mud or splash is generated. In particular, the mounting bolts of the lamp unit can be protected from the adhesion.
[0016]
Further, in the invention according to claim 5, by providing a splash guard at the opening edge of each harness insertion hole, the mounting bolt of the lamp unit is isolated from a region where mud or splash can penetrate, and the mounting bolt of the mounting bolt is separated. Protection can be further enhanced.
[0017]
【The invention's effect】
According to the first aspect of the present invention, the lamp accommodating recess is separated from the wheel house by the partition, and the lamp housing recess is configured to communicate only with the harness insertion hole formed in the partition. By offsetting the harness insertion holes formed in each of the brackets, mud and splash scattered as the wheels rotate are less likely to enter the lamp housing recess side, and the rear lamp unit itself, lamp bracket and mounting Bolts and the like can be protected from rusting due to adhesion of mud or splash. As a result, the service life of each component can be extended, and in the event that a specific component needs to be replaced, it can be dealt with only by replacing a single component, and the repair cost can be reduced. it can.
[0018]
In particular, according to the second aspect of the invention, since the positions of the harness insertion holes are offset in the two-dimensional directions of the height direction and the vehicle width direction, the intrusion of mud and splash is more reliably prevented. Thus, in addition to the same effect as the first aspect of the present invention, there is an effect that the rear lamp unit itself can be particularly protected from the adhesion of mud or splash.
[0019]
According to the third aspect of the present invention, the leg portion extends rearward from the lamp mounting wall portion of the lamp bracket to which the rear lamp unit is fixed, and the leg portion extends to the inner and lower surfaces of the lamp housing recess. Since the bolts are connected to each other, the mounting bolts of the lamp bracket can be moved as far as possible with respect to the direction in which mud or splash can penetrate, and in addition to the same effects as the invention according to claim 2, especially There is an effect that the mounting bolt of the lamp unit can be more reliably protected from the adhesion of mud or splash.
[0020]
According to the fourth aspect of the present invention, since the position of the lamp mounting bolt for fixing the rear lamp unit to the lamp bracket and each wire harness insertion hole are substantially offset, the position of the lamp harness insertion hole in the partition wall portion should be reduced. Even if mud or splash enters, they do not adhere to the lamp mounting bolt, and in addition to the same effect as the invention according to claim 3, in particular, the lamp mounting bolt is more reliably removed from the adhesion of mud or splash. There is an effect that can be protected.
[0021]
According to the invention described in claim 5, the surface of the partition wall portion on the side of the lamp mounting wall portion and the surface of the lamp mounting wall portion on the side of the partition wall portion, and correspond to the opening edge of each harness insertion hole. Since the splash guard protrudes toward the mating surface at the position, even if mud or splash enters through the harness insertion hole of the partition wall, it will prevent it from reaching the position of the lamp mounting bolt. Therefore, in addition to the same effect as the invention according to any one of claims 1 to 4, there is an effect that the lamp mounting bolt can be more reliably protected particularly from the adhesion of mud or splash.
[0022]
BEST MODE FOR CARRYING OUT THE INVENTION
FIGS. 1 to 3 show a typical embodiment of the present invention. In the forklift truck 1, a long rectangular lamp receiving recess 3 is formed from the rear surface of a counterweight 2 toward the front. The rear lamp unit 4 is accommodated and arranged in the accommodation recess 3 via the lamp bracket 5, and a vertical partition wall 6 is formed at the back of the lamp accommodation recess 3. The partition 6 separates the wheel house 8 in which the wheels 7 are housed from the lamp housing recess 3.
[0023]
The rear lamp unit 4 has an elongated shape in the vehicle width direction. The rear lamp unit 4 is fastened and fixed to a lamp mounting wall portion 11 of a lamp bracket 5 described later by a lamp mounting bolt 9 and a nut 10 penetrating both ends in the longitudinal direction. I have.
[0024]
The lamp bracket 5 is formed by bending a predetermined sheet metal material into a lamp mounting wall portion 11 and a leg portion 12 continuous with the lamp mounting wall portion 11 so as to have a substantially L-shaped cross section. The lamp bracket 5 is accommodated in the lamp accommodating recess 3 such that the rear side of the lamp mounting wall 11 to which the rear lamp unit 4 is fixed is parallel to the partition 6 and faces the same. Thus, the lamp bracket 5 has a leg 12 extending rearward from the lamp mounting wall 11, and the rear end of the leg 12 is bolted to the rear end of the lamp bracket 5 with the bracket mounting bolt 13. The whole 5 is fixed to the inner lower surface 3 a of the lamp housing recess 3.
[0025]
Here, a wire harness 14 for energization is connected to the rear lamp unit 4. The wire harness 14 is connected to a harness insertion hole 15 and a partition wall 6 formed in the lamp mounting wall 11 of the lamp bracket 5. After being passed through the formed harness insertion hole 16, it is routed to the wheel house 8 side. The two harness insertion holes 15 and 16 are offset from each other by a predetermined amount in the two-dimensional directions of the height direction and the vehicle direction so that their positions do not coincide with each other.
[0026]
Therefore, according to the present embodiment, the wheel house portion 8 and the lamp accommodating concave portion 3 are substantially separated by the partition wall portion 6, and both are communicated only with the necessary minimum harness insertion hole 16. Absent.
[0027]
Therefore, it is extremely rare that mud M or splash scattered with the rotation of the wheel 7 penetrates into the lamp accommodating recess 3 through the harness insertion hole 16, and the rear lamp unit 4 or the lamp bracket 5 adheres to the mud M or splash. Can be protected from. As a result, it is possible to prevent the rust of the lamp socket part on the rear side of the rear lamp unit 4 as well as the lamp bracket 5, the lamp mounting bolt 9 and the bracket mounting bolt 13, and to prolong the life of each part. become able to.
[0028]
As shown in FIGS. 1 and 3, even if mud M or splash passes through the harness insertion hole 16 of the partition wall 6, the harness insertion hole 16 on the partition wall 6 side faces the lamp mounting wall portion 11. Since the harness insertion hole 15 is offset, the mud M and splash can be prevented from entering the rear side of the rear lamp unit 4 from the harness insertion hole 15 on the lamp mounting wall portion 11 side.
[0029]
The above is exactly the same for the lamp mounting bolt 9. Since the positions of the lamp mounting bolt 9 and the nut 10 are offset with respect to the harness insertion holes 15 and 16, the partition wall 6 is Even if mud M or splash passes through the harness insertion hole 16, it does not reach the lamp mounting bolt 9 or the nut 10.
[0030]
Similarly, since the position of the bracket mounting bolt 13 is set so as to be farthest from the harness insertion hole 16 of the partition wall 6, mud M or splash passes through the harness insertion hole 16 of the partition wall 6. However, it is almost impossible to reach the position of the bracket mounting bolt 13.
[0031]
As described above, according to the present embodiment, the rear lamp unit 4, the lamp bracket 5, and the mounting bolts 9, 13 can be reliably protected from the adhesion of the mud M or the splash, and the rust due to the adhesion of the mud M or the splash can be prevented. Therefore, even when replacement of a specific part such as a lamp (bulb) is required, it can be dealt with only by replacing the single part.
[0032]
FIGS. 4 and 5 are views showing a second embodiment of the present invention. In this embodiment, the mutually facing surfaces of the partition wall 6 and the lamp bracket 5, that is, the lamp mounting wall of the partition wall 6. Splash guards 17, 18 protruding toward the mating side are provided at the opening edges of the harness insertion holes 15, 16 on the surface of the portion 11 and the partition wall 6 side of the lamp mounting wall portion 11. It is formed to protrude integrally. Although the tip of each of the splash guards 17 and 18 is in contact with the surface on the other side, the tip of each of the splash guards 17 and 18 is obliquely cut in consideration of the drawing property of the wire harness 14, and the lamp mounting bolts are cut. The portion near 9 is set to have the highest height.
[0033]
According to the present embodiment, as shown in FIG. 5, even if mud M or splash enters through the harness insertion hole 16 of the partition 6, the secondary rebound is prevented by the splash guards 17 and 18. In particular, the adhesion of mud M or splash to the lamp mounting bolt 9 or the nut 10 can be more reliably prevented.
[0034]
FIGS. 6 and 7 show a third embodiment of the present invention. In this embodiment, each of the harness insertion holes 15 and 16 is replaced with the cylindrical splash guards 17 and 18 shown in FIGS. And plate-like splash guards 19, 20 and 21, 22 having different heights are arranged on both sides of the opening edge of the opening.
[0035]
According to the present embodiment, the tip ends of the splash guards 19 and 21 having a large height are in contact with the lamp mounting wall portion 11 and the partition wall portion 6 which are mating sides, as well as the splash guards 19 and 21. The upper surface and the lower surface are also in contact with the upper and lower inner peripheral surfaces of the lamp accommodating recess 3, and substantially two large splash guards 19, 21 of the lamp accommodating recess 3, the partition wall portion 6 and the lamp mounting wall portion. The space surrounded by 11 is isolated from other spaces.
[0036]
Therefore, there is an advantage that the lamp mounting bolt 9 and the nut 10 can be more reliably protected from the adhesion of the mud M or the splash.
