Disclosure of Invention
Problems to be solved by the invention
In the rear panel of the cab disclosed in patent document 1, a reinforcing member is provided below a rear member extending in the vehicle width direction below a rear window. However, since the bead of the rear plate below the rear beam projects rearward in a region of a part of the rear plate (an intermediate portion between the lower end of the rear window and the lower end of the rear plate), it is difficult to sufficiently secure the strength of the rear plate with respect to a load input from above (or below) the cab in the region below the rear beam. Further, since the rear plate above the rear frame is not provided with a reinforcing member or the like, it is difficult to sufficiently secure the strength of the rear plate above the rear frame.
Accordingly, an object of the present disclosure is to provide a rear surface structure of a cab capable of sufficiently securing strength against a load input from the vertical direction.
Means for solving the problems
In order to solve the above problem, a first aspect of the present disclosure is a rear structure of a cab supported from below by a vehicle body frame, the rear structure including a rear panel and a reinforcement pillar. The rear plate has a projecting strip extending in the vertical direction in a state of projecting to one side in the front-rear direction, and stands up in the rear end portion of the cab so as to intersect with the front-rear direction. The reinforcing column has: the reinforcing column extends in the vertical direction so as to define a closed space between the reinforcing column and the ridge of the rear plate. The closed space extends over substantially the entire range of the rear plate in the vertical direction.
In the above configuration, the rib of the rear plate protrudes to one side in the front-rear direction, and the protruding portion of the reinforcement column protrudes to the other side in the front-rear direction, so that a larger cross-sectional area of the closed space between the rib of the rear plate and the reinforcement column can be ensured as compared with a case where one of the rear plate and the reinforcement column is flat. Therefore, the strength of the rear panel with respect to the vertical load input to the cab can be sufficiently ensured.
Further, since the closed space between the bead of the rear panel and the reinforcement column extends over substantially the entire range of the rear panel in the vertical direction, the strength of the rear panel with respect to the vertical load input to the cab can be sufficiently ensured.
Therefore, the strength of the rear surface of the cab with respect to the load input from the vertical direction can be sufficiently ensured.
A 2 nd aspect of the present disclosure is the rear structure of the cab of the 1 st aspect, including a rear mounting rail. The rear mounting rail has a supported surface portion supported from below by the vehicle body frame, and is joined to a lower end edge portion of the rear panel while extending in the vehicle width direction at a rear end lower portion of the cab. The rear mounting rail has a supported region including a supported surface portion within a predetermined range in the vehicle width direction. The lower end of one of the ribs and the reinforcing posts of the rear panel is fixed to the supported area of the rear mounting rail.
In the above configuration, the supported surface portion of the rear mounting rail is supported from below by the vehicle body frame, and the lower end portion of one of the bead of the rear panel and the reinforcing column is fixed to the supported region of the rear mounting rail. Therefore, the load input into the cab from above is transmitted from the bead and the reinforcing column to the vehicle body frame side via the supported region of the rear mounting rail, and the load input into the cab from below is transmitted to the bead and the reinforcing column side via the supported region of the rear mounting rail. In this way, since the load from above (the side of the bead and the reinforcing column) or the load from below (the side of the vehicle body frame) is efficiently transmitted in the vertical direction via the supported region of the rear mounting rail, it is possible to prevent the stress from concentrating on a predetermined portion of the rear surface portion of the cab, and it is possible to ensure the strength of the rear surface portion of the cab with respect to the vertical load input to the cab.
Further, since both the load from above and the load from below are input to the same region (supported region) of the rear mounting rail in the vehicle width direction, the rear mounting rail can be prevented from bending and deforming, and the strength of the rear surface portion of the cab can be ensured.
In the 3 rd aspect of the present disclosure, the protrusion may have right and left inclined surface portions and a front surface portion.
In the 4 th aspect of the present disclosure, the ridge may have right and left inclined surface portions and a rear surface portion.
In the 5 th aspect of the present disclosure, the reinforcing column may be disposed on the front side in the front-rear direction with respect to the bead.
Effects of the invention
According to the present disclosure, the strength of the rear surface of the cab with respect to the load input from the vertical direction can be sufficiently ensured.

Detailed Description
Hereinafter, one embodiment of the present disclosure will be described based on the drawings. IN each of the drawings, FR denotes a front of the vehicle, UP denotes an upper side, and IN denotes a vehicle width direction inner side. In the following description, the left-right direction means a left-right direction in a state of being directed toward the front of the vehicle.
As shown in fig. 1, the rear structure of the cab of the present embodiment is applied to a cab 10 of a flathead truck 1 in which the cab 10 is disposed substantially above an engine (not shown).
As shown in fig. 2, the truck 1 includes: a left-right 1-pair side member 2 extending across the front and rear of the vehicle; and a plurality of cross members 3 extending in the vehicle width direction and connecting the left and right side members 2. The left and right side members 2 and the plurality of cross members 3 constitute a body frame 4 of the truck 1. The front lower portion of the cab 10 is rotatably supported at the front end portion of the vehicle body frame 4 via a front cab bracket (not shown). The rear end of the cab 10 is supported from below by the vehicle body frame 4 via the rear cab brackets 5 fixed to the left and right side members 2. The rear cab bracket 5 has a cushion rubber (not shown) on its upper surface, and elastically supports a rear cab attachment bracket 6, which will be described later, from below via the cushion rubber. In addition, in fig. 2, only 1 cross member 3 is shown.
As shown in fig. 2 to 4, the cab 10 includes a rear cab mounting rail (rear mounting rail) 11, a rear panel 12, and left and right 1 pairs of reinforcing pillars 13, and the cab 10 is disposed above the front portion of the body frame 4 of the truck 1 and supported from below by the body frame 4. The rear cab attachment rail 11, the rear plate 12, and the left and right reinforcement pillars 13 constitute a rear portion 7 of the cab 10 (hereinafter referred to as a cab rear portion 7) that defines the rear of the cab 10. In fig. 4, only the reinforcing column 13 on the left side is shown.
As shown in fig. 2 to 5, the rear cab attachment rail 11 is a portion of a floor panel 14 that defines a lower portion of the cab 10, and is formed by bending a rear end side of the floor panel 14 so as to protrude upward, and the rear cab attachment rail 11 extends in the vehicle width direction at a lower portion of a rear end of the cab 10, thereby ensuring rigidity of a rear end edge portion of the floor panel 14. The rear cab attachment rail 11 includes a front plate portion 11a standing on the rear end portion of the floor panel 14, an upper plate portion 11b bent from the upper end edge of the front plate portion 11a and extending rearward, and a rear plate portion 11c bent from the rear end edge 27 of the upper plate portion 11b and extending downward, and is formed in an open cross-sectional shape open downward, and defines a space 8 inside thereof. The upper plate portion 11b of the rear cab attachment rail 11 has left and right 1 pairs of attachment bracket fixing portions (supported surface portions) 15. The left and right rear cab attachment brackets 6 1 to the rear are disposed below the left and right attachment bracket fixing portions 15, and are fixed to the left and right attachment bracket fixing portions 15. The rear cab attachment rail 11 has a pair of left and right 1 supported regions 25, and the pair of left and right 1 supported regions 25 are regions including the attachment bracket fixing portions 15 in a predetermined range in the vehicle width direction. The left and right supported regions 25 are regions stronger in supporting force from the rear cab legs 5 than other regions, and each have a mounting bracket fixing portion 15, a front region 26, and a rear region (not shown). The front region 26 of the supported region 25 is a region extending downward from the front end edge of the mounting bracket fixing portion 15 in the front plate portion 11a of the rear cab mounting rail 11. The rear region of the supported region 25 is a region extending downward from the rear end edge of the mounting bracket fixing portion 15 in the rear plate portion 11c of the rear cab mounting rail 11. The vehicle width direction lengths of the front region 26 and the rear region of the supported region 25 are substantially the same as the vehicle width direction length of the mounting bracket fixing portion 15. That is, the length of the supported region 25 in the vehicle width direction, that is, the length of the predetermined range is substantially the same as the length of the mounting bracket fixing portion 15 in the vehicle width direction.
As shown in fig. 2, 3, and 5, left and right rear cab attachment brackets 6 are formed of plate bodies into a frame shape that penetrates in the front-rear direction, and have locking devices (not shown) that can lock rear cab brackets 5 on the inner sides thereof. The left and right rear cab attachment brackets 6 each integrally include an upper plate portion 6a fixed in a state of surface contact with the attachment bracket fixing portion 15 of the rear cab attachment rail 11 from below and a lower plate portion 6b supported by the rear cab bracket 5 from below, and the left and right rear cab attachment brackets 6 are disposed in the space 8 below the rear cab attachment rail 11. That is, the left and right mounting bracket fixing portions 15 of the rear cab mounting rail 11 are supported from below by the vehicle body frame 4 via the left and right rear cab mounting brackets 6 and the rear cab brackets 5, and the cab rear surface portion 7 is supported from below by the vehicle body frame 4.
The left and right mounting bracket fixing portions 15 of the rear cab mounting rail 11 are portions of the upper plate portion 11b of the rear cab mounting rail 11 that are surface-contacted from below by the upper plate portion 6a of the rear cab mounting bracket 6 and are supported from below by the rear cab brackets 5 via the rear cab mounting bracket 6, and the length of the mounting bracket fixing portions 15 in the vehicle width direction is substantially the same as the length of the upper plate portion 6a of the rear cab mounting bracket 6 in the vehicle width direction. In the present invention, the substantially same concept means the following concept: the term "identical" includes not only completely identical but also a state that is somewhat different due to manufacturing errors and the like.
As shown in fig. 5 and 6, the rear plate 12 is a plate body that defines the rear of the cab 10, has 1 pair of left and right projections 17 extending in the vertical direction, and stands on the rear end of the cab 10 along the rear cab attachment rail 11. The rear panel 12 is formed by being curved such that a central portion in the vehicle width direction protrudes rearward from both end portions in the vehicle width direction. The lower end edge portion of the rear plate 12 is disposed rearward of the rear plate portion 11c of the rear cab attachment rail 11, and is joined to the rear plate portion 11 c. A roof rear rail 16 (see fig. 4) extending in the vehicle width direction is fixed to an upper end edge portion of the rear panel 12 on the front surface 21 side in a state of protruding forward, and defines a closed cross section with the rear panel 12 to reinforce the upper end edge portion of the rear panel 12. A rear end edge portion of a roof panel 18 (see fig. 3 and 4) defining an upper portion of the cab 10 is fixed to an upper end edge portion of the rear panel 12. Both end edge portions of the rear panel 12 in the vehicle width direction are fixed to rear end edge portions of an outer panel 19 and rear end edge portions of an inner panel 20 on both sides of the cab 10 in the vehicle width direction. Both end edge portions of the rear panel 12 in the vehicle width direction, a rear end edge portion of the outer panel 19, and a rear end edge portion of the inner panel 20 are joined to each other in a state of extending in the vertical direction so as to project rearward of the cab 10 and overlapping each other in the vehicle width direction.
The left and right beads 17 extend in the vertical direction over the upper and lower sides of the rear panel 12 in a state of protruding to one side in the front-rear direction (the rear side in the present embodiment), and are provided on both sides of the rear panel 12 in the vehicle width direction in left-right symmetry so as to reinforce the rear panel 12. Each bead 17 has left and right inclined surface portions 17a, 17b and a rear surface portion (flat surface portion) 17c, and is disposed at substantially the same position in the vehicle width direction as the left and right supported regions 25 of the rear cab attachment rail 11. Specifically, the center line of the bead 17 in the vehicle width direction and the center line of the mounting bracket fixing portion 15 of the rear cab mounting rail 11 in the vehicle width direction are arranged at substantially the same position in the vehicle width direction (the position indicated by the two-dot chain line 9 in fig. 2). The left and right inclined surfaces 17a and 17b of the ridge 17 extend obliquely in a direction approaching each other rearward. The rear surface portion 17c of the ridge 17 intersects the front-rear direction and connects the rear end edges of the left and right inclined surface portions 17a, 17 b.
The left and right reinforcing columns 13 are formed in a hat (hat) shape in cross section having left and right fixing surface portions 13a, 13b, left and right inclined surface portions 13c, 13d, and a front surface portion (flat surface portion) 13e, respectively. The protruding portion of the reinforcing column is formed by the left and right inclined surface portions 13c, 13d and the front surface portion (flat surface portion) 13 e. The left and right reinforcing columns 13 are disposed at positions facing the left and right protrusions 17 from the front in the front-rear direction other surface 21 (front surface 21 in the present embodiment) of the rear plate 12, are fixed to the front surface 21 of the rear plate 12, and extend in the vertical direction. That is, since the center line of the left and right reinforcing pillars 13 in the vehicle width direction and the center line of the mounting bracket fixing portion 15 of the rear cab mounting rail 11 in the vehicle width direction are arranged at substantially the same position in the vehicle width direction (the position indicated by the two-dot chain line 9 in fig. 2) as the left and right projecting portions 17 of the rear panel 12, the left and right reinforcing pillars 13 as a whole and the left and right supported regions 25 of the rear cab mounting rail 11 are arranged at substantially the same position in the vehicle width direction. The upper ends of the left and right reinforcing columns 13 are disposed at the upper end edge of the rear plate 12. The roof rear rail 16 (see fig. 4) is fixed to the rear panel 12 so as to cover the upper ends of the left and right reinforcement pillars 13 from the front. The lower ends of the left and right reinforcing posts 13 are close to the upper surface of the mounting bracket fixing portion 15 of the rear cab mounting rail 11. The left and right fixing surface portions 13a, 13b are joined to regions on the left and right sides of the ridge 17 in the front surface 21 of the rear plate 12. The left and right inclined surface portions 13c and 13d extend in a direction in which end edge portions of the left and right fixing surface portions 13a and 13b on the ridge 17 side approach each other forward. The front surface portion 13e faces the rear surface portion 17c of the ridge 17 at a position spaced forward from the rear surface portion 17c, intersects the front-rear direction, and connects front end edges of the left and right inclined surface portions 13c, 13 d. That is, the left and right inclined surfaces 13c and 13d and the front surface 13e protrude toward the other side (the front side in the present embodiment) in the front-rear direction between the left and right fixing surfaces 13a and 13 b. The front surface portion 13e of the reinforcing column 13 is disposed at substantially the same position as the rear end edge of the mounting bracket fixing portion 15 in the front-rear direction, of the rear end edge 27 of the upper plate portion 11b of the rear cab mounting rail 11. An L-shaped bracket 23, which will be described later, is fixed to a lower end 28 of the front face 13e of the reinforcing column 13. The right and left reinforcing columns 13, in a state of being fixed to the rear panel 12, define a closed space 22 having a substantially hexagonal cross section with the ridge 17 of the rear panel 12, thereby reinforcing the rear panel 12. The closed space 22 between the reinforcement pillar 13 and the rear panel 12 extends in the vertical direction over substantially the entire vertical range of the rear panel 12. In the present disclosure, the closed space 22 extends over substantially the entire range of the rear plate 12 in the vertical direction means the following concept: the closed space 22 extends continuously from the upper end edge to the lower end edge of the rear panel 12, and extends over the entire range in the vertical direction of the middle portion of the rear panel 12 except for the lower end edge portion joined to the rear cab attachment rail 11 and the upper end edge portion joined to the roof rear rail 16. The closed space in the above embodiment is not limited to a completely closed space, and an opening may be formed at the upper end or the lower end of the bead 17 or the reinforcing column 13, or a hole for fixing or attaching a member may be formed in the bead 17 or the reinforcing column 13.
As shown in fig. 4 and 5, the bracket 23 integrally includes: a vertical plate portion 23a extending in the vertical direction as viewed from the vehicle side; and a front plate portion 23b bent from the lower end of the vertical plate portion 23a and extending forward. The upper end of the vertical plate 23a is fixed to the front surface 24 of the front surface 13e of the reinforcing column 13, and the lower end of the vertical plate 23a abuts against the upper surface of the mounting bracket fixing portion 15. The front plate portion 23b extends along the upper surface of the mounting bracket fixing portion 15, and is fixed to the mounting bracket fixing portion 15 by welding or the like. That is, the lower end 28 of the reinforcing column 13 is fixed to the mounting bracket fixing portion 15 of the supported region 25 of the rear cab mounting rail 11 via the bracket 23. The shape of the bracket 23 is not limited to the substantially L shape, and may be other shapes as long as one end side thereof is fixed to the lower end portion 28 of the reinforcement pillar 13 and the other end side thereof is fixed to the supported region 25 of the rear cab attachment rail 11.
In the cab 10 configured as described above, since the left and right ribs 17 of the rear panel 12 project rearward and the left and right inclined surface portions 13c and 13d and the front surface portion 13e of the reinforcement pillar 13 project forward, the cross-sectional area of the closed space 22 between the ribs 17 of the rear panel 12 and the reinforcement pillar 13 can be ensured to be larger than in the case where one of the rear panel 12 and the reinforcement pillar 13 is flat. Therefore, the strength of the rear panel 12 against the vertical load input to the cab 10 can be sufficiently ensured.
Further, since the closed space 22 between the bead 17 of the rear panel 12 and the reinforcement column 13 extends over substantially the entire range of the rear panel 12 in the vertical direction, the strength of the rear panel 12 against the vertical load input to the cab 10 can be sufficiently ensured.
Therefore, the strength of the cab rear surface portion 7 with respect to the load input from the vertical direction can be sufficiently ensured.
The mounting bracket fixing portion 15 of the rear cab mounting rail 11 is supported from below by the vehicle body frame 4, and the lower end portion 28 of the reinforcement column 13 is fixed to the supported region 25 of the rear cab mounting rail 11 via the bracket 23. Therefore, the load input into the cab 10 from above is transmitted from the bead 17 and the reinforcement column 13 to the vehicle body frame 4 side through the supported region 25 of the rear cab attachment rail 11, and the load from below the cab 10 is transmitted to the bead 17 and the reinforcement column 13 side through the supported region 25 of the rear cab attachment rail 11. In this way, since the load from above (the bead 17 and the reinforcing column 13 side) or the load from below (the vehicle body frame 4 side) is efficiently transmitted in the vertical direction via the supported region 25 of the rear cab attachment rail 11, stress can be prevented from concentrating on a predetermined portion of the cab rear portion 7, and the strength of the cab rear portion 7 with respect to the vertical load input to the cab 10 can be ensured.
Further, since both the load from above and the load from below are input to the same region (supported region 25) of the rear cab attachment rail 11 in the vehicle width direction, the bending deformation of the rear cab attachment rail 11 can be prevented, and the strength of the cab rear portion 7 can be ensured.
In the present embodiment, the rear cab attachment rail 11 formed by bending the rear end side of the floor panel 14 so as to protrude upward is provided, but the present invention is not limited to this, and other configurations are possible as long as the rear cab attachment rail extends in the vehicle width direction at the lower portion of the rear end of the cab 10 and is supported from below by the vehicle body frame 4. For example, the rear cab attachment rail may be a tubular body having a rectangular cross section or the like, which is fixed to the rear end edge portion of the floor panel 14 and extends in the vehicle width direction.
In the present embodiment, since the rear cab attachment bracket 6 is fixed to the attachment bracket fixing portion 15 of the rear cab attachment rail 11, the attachment bracket fixing portion 15 is supported from below by the rear cab bracket 5 via the rear cab attachment bracket 6, and the attachment bracket fixing portion 15 functions as a supported surface portion, but is not limited thereto. For example, a predetermined region of the rear cab attachment rail 11 may be directly supported from below by the cushion rubber of the rear cab bracket 5, and the predetermined region may function as a supported surface portion. In this case, a portion of the rear cab attachment rail 11 that contacts the cushion rubber of the rear cab bracket 5 is a supported surface portion, and the length in the vehicle width direction of the predetermined region is the length in the vehicle width direction of the supported region including the supported surface portion.
In the present embodiment, the front plate portion 23b of the bracket 23 is fixed to the mounting bracket fixing portion 15 of the rear cab mounting rail 11, but is not limited to this, and may be fixed to another portion (the front region 26, the rear region, or the like) of the supported region 25.
Although the lower end 28 of the reinforcing column 13 is fixed to the supported region 25 of the rear cab mounting rail 11 via the bracket 23 in the present embodiment, the bracket 23 is not necessarily provided, and may be directly fixed to the supported region 25 of the rear cab mounting rail 11 by welding or the like.
The cross-sectional shape of the closed space 22 defined between the ridge 17 of the rear plate 12 and the reinforcing column 13 is not limited to a hexagonal shape, and may be, for example, a rectangular shape or a circular shape.
Although the present invention has been described above based on the above embodiments, the present invention is not limited to the contents of the above embodiments, and it goes without saying that modifications may be made as appropriate without departing from the scope of the present invention. That is, it is needless to say that other embodiments, examples, application techniques, and the like, which are completed based on the present embodiment by those skilled in the art, are all included in the scope of the present invention.
For example, in the above embodiment, the protrusion 17 of the rear plate 12 is protruded to the rear side, and the reinforcement column 13 is protruded to the front side, but the protrusion 17 of the rear plate 12 may be protruded to the front side (one side in the front-rear direction) and the reinforcement column 13 may be protruded to the rear side (the other side in the front-rear direction). In this case, the lower end portion of the bead 17 of the rear panel 12 may be fixed to the supported region 25 of the rear cab mounting rail 11.
In the above embodiment, the rear structure of the cab according to the present invention is applied to the cab 10 of the truck 1 having a normal roof height, but the present invention is not limited to this, and may be applied to a cab of a high-roof type truck, a cab of a tractor or the like that pulls a trailer, or the like.
The present application is based on Japanese patent application No. 2016 (043753) filed on 7/3/2016, the contents of which are hereby incorporated by reference.
