Summary of the Invention

Problems to be Solved by the Invention

[0004] Conventionally, the shape and size of a subframe are generally designed according to, for example, the vehicle type on which the subframe is mounted and the types of accessories held by the subframe. Therefore, since the applicable vehicle types and accessories of conventional subframes are limited, there is room for improvement in terms of versatility.

[0005] An object of one aspect of the present disclosure is to provide a subframe that contributes to an improvement in versatility.

Means for Solving the Problems

[0006] A subframe according to one aspect of the present disclosure is a subframe mounted on a vehicle for holding auxiliary equipment, and includes a lower frame attached to a vehicle body frame located below in the vehicle height direction, and a plurality of upper frames that can be stacked in stages along the vehicle height direction above the lower frame, wherein each of the plurality of upper frames has an upper surface portion that forms a horizontal plane and to which the auxiliary equipment is fixed, and a plurality of legs that extend vertically downward from the upper surface portion and are fixed to the lower frame or the upper frame located directly below, wherein the lowermost of the plurality of upper frames is fixed on the lower frame, and at least one or more of the upper frames are stacked above the upper frame, the upper surfaces of each of the plurality of upper frames are parallel to each other, and the area of ​​the upper surface portion of each of the plurality of upper frames is equal or decreases as you go upward. [Effects of the Invention]

[0007] This disclosure can contribute to improving versatility. [Brief explanation of the drawing]

[0008] [Figure 1] Exploded perspective view of a subframe according to an embodiment of the present disclosure [Figure 2] Partial enlarged view of Figure 1 [Modes for carrying out the invention]

[0009] The subframe 100 of this embodiment will be described below with reference to Figures 1 and 2. Figure 1 is an exploded perspective view of the subframe 100. Figure 2 is an enlarged view of the dotted line portion in Figure 1.

[0010] The subframe 100 is a structural frame mounted on a vehicle (for example, an automobile). The subframe 100 is used to hold various auxiliary components (not shown) mounted on the vehicle.

[0011] As shown in Figure 1, the subframe 100 has one lower frame 10 and two upper frames 20 and 30.

[0012] The lower frame 10 is mounted on the vehicle body frame (not shown) located below the vehicle height direction C. Known techniques (e.g., bolting) can be used for mounting.

[0013] The lower frame 10 has a plurality of first elongated members 11 extending along the vehicle width direction A (an example of a first direction) and a plurality of second elongated members 12 extending along the vehicle length direction B (an example of a second direction perpendicular to the first direction). The cross-sections of the first elongated members 11 and the second elongated members 12 are U-shaped (an example of an R-shape). A U-shape is a shape in which the center is R-shaped and both sides are symmetrical and parallel.

[0014] The first elongated member 11 has a plurality of slits 13 provided at predetermined intervals in the vehicle width direction A. The second elongated member 12 is fitted into the slits 13 and assembled with the first elongated member 11. As shown in Figure 2, when the first elongated member 11 and the second elongated member 12 are assembled, their R shapes face each other. The assembled second elongated member 12 and the first elongated member 11 are fixed together by welding. Part a shown in Figure 2 is the welded portion.

[0015] The upper frames 20 and 30 can be stacked in stages along the vehicle height direction C above the lower frame 10.

[0016] The upper frame 20 has an upper surface portion 21 and leg portions 22. The upper frame 30 has an upper surface portion 31 and leg portions 32. The upper frame 20 and the upper frame 30 are almost identical in shape, but the upper frame 30 is smaller than the upper frame 20.

[0017] The upper surfaces 21 and 31 are horizontally oriented surfaces to which various auxiliary components are fixed.

[0018] The plurality of leg portions 22 extend in a vertically downward direction (downward in the vehicle height direction C) from the upper surface portion 21 and are fixed to the lower-stage frame 10 disposed directly below (specifically, the upper surface portion 14 of the second long member 12). As a fixing method, a method of inserting a bolt (not shown) into a through hole (not shown) provided in the upper surface portion 14 and a through hole (not shown) provided in the leg portion 22 and fastening with a nut (not shown) can be used, but it is not limited thereto.

[0019] The plurality of leg portions 32 extend in a vertically downward direction (downward in the vehicle height direction C) from the upper surface portion 31 and are fixed to the upper-stage frame 20 disposed directly below (specifically, the upper surface portion 21). As a fixing method, a method of inserting a bolt (not shown) into a through hole (not shown) provided in the upper surface portion 21 and a through hole (not shown) provided in the leg portion 32 and fastening with a nut (not shown) can be used, but it is not limited thereto.

[0020] As described above, the upper-stage frame 20 is fixed to the lower-stage frame 10, and the upper-stage frame 30 is fixed to the upper-stage frame 20, whereby the sub-frame 100 is completed. In this state, the upper surface portion 21 of the upper-stage frame 20 and the upper surface portion 31 of the upper-stage frame 30 are parallel to each other. Also, the area of the upper surface portion 31 is smaller than the area of the upper surface portion 21. Thus, in the present embodiment, in the plurality of stacked upper-stage frames, each upper surface portion is parallel to each other, and the area of each upper surface portion becomes smaller as it goes upward.

[0021] In the present embodiment, the case where there is one upper-stage frame (in the present embodiment, only the upper-stage frame 30) stacked on the lowermost upper-stage frame 20 is taken as an example, but two or more may be used.

[0022] Also, in the present embodiment, the case where the area of the upper surface portion becomes smaller as it goes upward is taken as an example, but the areas of the plurality of upper-stage frames may be equal. For example, in FIG. 1, instead of the upper-stage frame​​​As described above, the sub-frame 100 of the present embodiment is a sub-frame mounted on a vehicle for holding accessories, and includes a lower frame attached to a body frame positioned below in the vehicle height direction, and a plurality of upper frames that can be stacked stepwise along the vehicle height direction above the lower frame. The plurality of upper frames each form a surface along the horizontal direction, and have an upper surface portion to which accessories are fixed, and a plurality of leg portions that extend vertically downward from the upper surface portion and are fixed to the lower frame or the upper frame disposed directly below. Among the plurality of upper frames, the lowermost upper frame is fixed on the lower frame, and in a state where at least one or more upper frames are stacked above the upper frame, the upper surface portions of the plurality of upper frames are parallel to each other, and the areas of the upper surface portions of the plurality of upper frames are equal or decrease upward.

[0024] Due to this feature, the number of upper frames can be selected according to the vehicle type and accessories, which can contribute to improving versatility.

[0025] Note that the present disclosure is not limited to the description of the above embodiment, and various modifications are possible without departing from the spirit thereof.

Industrial Applicability

[0026] The sub-frame of the present disclosure is useful for holding auxiliary machines in a vehicle.
