[Diagram 3] FIG. 3 is a view showing the bracket in FIG. 2(b) from a different angle. [Figure 4] FIG. 3 is a view showing the bracket in FIG. 2(a) from a different angle. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] A vehicle load fixing structure according to one embodiment of the present invention includes a floor panel of a vehicle, a frame member installed on the floor panel in a state surrounding a predetermined load, and a bracket installed on the floor panel to connect the floor panel and the frame member, wherein the frame member has a frame protrusion protruding downward, and the bracket has a support surface portion that supports the frame member, a bracket sliding portion that protrudes upward from the support surface portion and contacts the frame member, and a bracket insertion portion formed on the support surface portion and into which the frame protrusion can be inserted, and the bracket insertion portion is located on the path of the frame protrusion when the frame member is slid along the bracket sliding portion.

[0010] According to the above configuration, by sliding the frame member along the bracket sliding portion, the frame protrusion portion can be inserted into the bracket insertion portion, making it easy to align the frame member on the floor panel. Therefore, according to the above configuration, the work of assembling the load to the floor panel can be made easier, and it is possible to improve the assembling accuracy and reduce the work effort.

[0011] The support surface portion of the bracket is formed as a top surface of the bracket facing upward in the vehicle, thereby preventing the frame member from colliding with and damaging the floor panel when the frame member is placed on the floor panel. The support surface portion may be configured to support the weight of the frame member while being in contact with the frame member. For example, if the frame member has a rectangular cross section, the support surface portion may be provided in a planar shape. Also, if the frame member has a shape with a curvature, the support surface portion may be provided in a curved shape corresponding to the curvature of the frame member. Furthermore, a plurality of bracket sliding portions may be provided, and in this case, the frame member may be brought into contact with each bracket sliding portion, making it easier to adjust the position of the frame member.

[0012] The bracket sliding portion may have an inclined portion that extends obliquely from the upper end side toward the bracket insertion portion.

[0013] According to the above configuration, by lowering the frame member along the inclined portion of the bracket sliding portion, the frame protrusion portion can be guided to the bracket insertion portion, and the positioning of the frame member on the floor panel can be made easier. In addition, when a plurality of bracket sliding portions are provided, the inclined portions can be arranged to face each other. For example, when two inclined portions are arranged to face each other in the vehicle longitudinal direction, by lowering the frame member between the two inclined portions, the frame member comes into contact with one of the inclined portions and descends along it, and then comes into contact with the other contact portion, thereby adjusting the position in the longitudinal direction, and the frame member can be easily installed at the desired position. In addition, the plurality of inclined portions can be arranged to face each other in the vehicle width direction, which makes it easier to adjust the position of the frame member in the vehicle width direction.

[0014] The bracket may further have a bracket leg portion extending from an edge of the support surface portion towards the floor panel and joined to the floor panel, and the support surface portion may be spaced apart from the floor panel.

[0015] According to the above configuration, when the frame protrusion is inserted into the bracket insertion portion formed on the support surface portion, the tip of the frame protrusion is prevented from interfering with the floor panel, making it possible to precisely join the frame member and the bracket.

[0016] The bracket sliding portion may be bent upward and extend from the support surface portion, and the bracket may further have a bead that bulges upward in a region extending from the bracket sliding portion to the support surface portion and the bracket leg portion.

[0017] According to the above configuration, by increasing the rigidity of the bracket sliding portion by the bead, deformation of the bracket sliding portion can be suppressed, and the assembly precision between the frame member and the bracket can be improved.

[0018] The bracket insertion portion may include a large diameter portion having a predetermined diameter, and a small diameter portion provided continuously with an end portion in the vehicle width direction of the large diameter portion and having a smaller diameter than the large diameter portion.

[0019] According to the above configuration, by sliding the frame member along the bracket sliding portion to insert the frame protrusion into the bracket insertion portion, and then sliding the frame protrusion toward the small diameter portion of the bracket insertion portion to engage it, it becomes easier to align the frame member on the floor panel and also makes it possible to improve assembly accuracy.

[0020] The vehicle cargo fixing structure further includes a pair of side members extending along the side edges of the floor panel, a cross member spanning the pair of side members on the underside of the floor panel, and a brace spanning the cross member and the side members, and the bracket is preferably installed in an area of ​​the floor panel surrounded by the side members, the cross member, and the brace.

[0021] According to the above configuration, by installing the bracket in a highly rigid area of ​​the floor panel surrounded by the side members, cross members, and braces, it is possible to install cargo on the floor panel with higher rigidity. EXAMPLES

[0022] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The dimensions, materials, and other specific values ​​shown in the embodiments are merely examples for facilitating understanding of the invention, and do not limit the present invention unless otherwise specified. In this specification and drawings, elements having substantially the same functions and configurations are given the same reference numerals to avoid repeated explanations, and elements not directly related to the present invention are not shown.

[0023] Fig. 1 is a diagram showing an overview of a vehicle load fixing structure (hereinafter, fixing structure 100) according to an embodiment of the present invention. Fig. 1(a) is a diagram showing the front of a vehicle to which the fixing structure 100 is implemented. Hereinafter, in Fig. 1 and all other drawings of the present application, the front-rear direction of the vehicle is indicated by arrows F (Forward) and B (Backward), the left and right in the vehicle width direction are indicated by arrows L (Leftward) and R (Rightward), and the up-down direction of the vehicle is indicated by arrows U (Upward) and D (Downward).

[0024] The fixing structure 100 of this embodiment is intended to facilitate the alignment of a load 104 having a certain weight when the load 104 is installed on the floor panel 102. Examples of the load 104 include batteries and CNG (compressed natural gas) gas containers. These loads 104 are large and heavy among vehicle parts, and there is a demand for facilitating the installation work.

[0025] The floor panel 102 in this embodiment is assumed to be a rear panel behind the rear seats. A tire storage section 106 for storing a spare tire is formed on the rear end side of the floor panel 102. A load 104, shown by a dashed line, is installed above the tire storage section 106 via a frame member 108.

[0026] Frame member 108 is a frame-shaped member that surrounds load 104, and is fixed to side members 150a, 150b, etc. after being installed on floor panel 102 and aligned. Frame member 108 has horizontal frame portions 110, 112 that extend in the vehicle width direction along the front and rear sides of load 104, and vertical frame portions 114, 116 that extend in the front-rear direction along the sides of load 104.

[0027] The fixing structure 100 can be adjusted to a desired position on the floor panel 102 by using a bracket 118 for the front horizontal frame portion 110.

[0028] Fig. 2 is an enlarged view of the bracket 118 in Fig. 1. Fig. 2(a) is an enlarged view of the bracket 118 installed on the floor panel 102.

[0029] Bracket 118 is a member that connects frame member 108 (see FIG. 1) and floor panel 102. In this embodiment, bracket 118 is installed on the right side of the upper surface of floor panel 102 in the vehicle width direction, and is used to align the position of the right end side of frame member 108.

[0030] Fig. 2(b) is a view showing only the bracket 118 of Fig. 2(a). The bracket 118 is mainly made of metal, and is attached to the floor panel 102 (see Fig. 2(a)) by welding or the like.

[0031] The support surface portion 120 is a flat portion that forms the top surface of the bracket 118, and a bracket insertion portion 130 (described later) is open at the center. The support surface portion 120 in this embodiment is formed so that its surface faces upward in the vehicle, and the frame member 108 slides from above. The support surface portion 120 is disposed approximately parallel to the floor panel 102 (see FIG. 2(a)), and is configured to be located between the frame member 108 (see FIG. 1) and the floor panel 102.

[0032] By forming the support surface portion 120 as the top surface of the bracket 118 facing upward in the vehicle, it is possible to prevent the frame member 108 (see FIG. 1) from colliding with and damaging the floor panel 102 when the frame member 108 is placed on the floor panel 102.

[0033] The supporting surface portion 120 may have any configuration as long as it can support the weight of the frame member 108 while being in contact with the frame member 108. Therefore, for example, if the frame member 108 (see FIG. 1) is a member having a rectangular cross section, the supporting surface portion 120 can be set to a planar shape facing upward toward the vehicle in accordance with the lower surface of the frame member 108. In addition, for example, if the frame member 108 has a shape having a curved shape, the supporting surface portion 120 can also be set to a curved shape corresponding to the curvature of the frame member 108.

[0034] The bracket legs 122, 124 are flange-shaped portions that come into contact with the floor panel 102 (see FIG. 2(a)), and extend from both edges of the support surface portion 120 in the vehicle width direction while bending toward the floor panel 102, and are in surface contact with the floor panel 102. The bracket legs 122, 124 are joined to the floor panel 102 by welding or the like.

[0035] The bracket sliding parts 126, 128 are parts that come into contact with and guide the frame horizontal frame part 110 (see FIG. 1), and are provided so as to protrude upward from the support surface part 120. The front bracket sliding part 126 extends from the front edge of the support surface part 120, bending upward, while the rear bracket sliding part 128 extends from the rear edge of the support surface part 120, bending upward.

[0036] The bracket insertion portion 130 is a portion into which a pin of the frame member 108 (see FIG. 1) is inserted. Specifically, a frame protrusion 132 is provided on the underside of a frame horizontal frame portion 110 (see FIG. 4(b)), which will be described later, and this frame protrusion 132 is inserted into the bracket insertion portion 130.

[0037] Fig. 3 is a diagram showing the bracket 118 in Fig. 2(b) from a different direction. Fig. 3(a) is a diagram showing the bracket 118 in Fig. 2(b) as viewed from above.

[0038] The bracket insertion portion 130 is provided in the shape of an elongated hole with its major axis extending in the vehicle width direction at the center of the support surface portion 120. The bracket sliding portions 126, 128 are provided on the front and rear sides of the bracket insertion portion 130, and guide the frame protrusion portion 132 (see FIG. 4(b)) into the bracket insertion portion 130.

[0039] The bracket sliding portion 126 has a base 136 provided along the front edge of the support surface portion 120, and an end portion 140 formed by bending from the base 136 to the rear side where the bracket insertion portion 130 is located. The bracket sliding portion 128 has a base 138 provided along the rear edge of the support surface portion 120, and an end portion 142 formed by bending from the base 138 to the front side where the bracket insertion portion 130 is located.

[0040] Fig. 3(b) is a view showing the bracket 118 of Fig. 3(a) as seen from the left side of the vehicle. Ends 140, 142 of the bracket sliding parts 126, 128 are formed in a triangle shape protruding from the base parts 136, 138 toward the center of the support surface part 120.

[0041] The bracket sliding portions 126, 128 have inclined portions 144, 146 formed as hypotenuses of the ends 140, 142 of the triangle. The inclined portions 144, 146 have the function of guiding the frame horizontal portion 110 by sliding it down toward the center of the support surface portion 120 when the frame horizontal portion 110 (see FIG. 4(b)) is placed on the bracket 118. The inclined portions 144, 146 make it easier to align the frame member 108 on the floor panel 102.

[0042] In this embodiment, the two inclined portions 144, 146 are disposed to face each other in the front-rear direction. The inclined portion 144 extends from the upper end side of the bracket sliding portion 126 toward the center side of the support surface portion 120 on which the bracket insertion portion 130 is formed, slanting downward toward the rear. The inclined portion 146 extends from the upper end side of the bracket sliding portion 128 toward the center side of the support surface portion 120 on which the bracket insertion portion 130 is formed, slanting downward toward the front.

[0043] Fig. 4 is a diagram showing the bracket 118 in Fig. 2(a) from a different direction. Fig. 4(a) is a diagram showing the bracket 118 in Fig. 2(a) as viewed from above.

[0044] The fixing structure 100 includes side members 150 a and 150 b (see FIG. 1), a cross member 152 , and a brace 154 .

[0045] The side members 150a, 150b are members that extend in the front-rear direction of the vehicle along the side edges of the floor panel 102, and are provided in pair on the left and right sides of the floor panel 102.

[0046] Cross member 152 is a member extending in the vehicle width direction below floor panel 102, with both ends joined to side members 150a, 150b, respectively, and installed in a state in which it spans side members 150a, 150b.

[0047] The brace 154 is a diagonal member that spans between the cross member 152 and the side member 150b.

[0048] In this embodiment, the bracket 118 is installed in an area of ​​the floor panel 102 that is surrounded by the side member 150b, the cross member 152, and the brace 154. The area of ​​the floor panel 102 that is surrounded by the side member 150a, the cross member 152, and the brace 154 has high rigidity. By installing the bracket 118 in this area, the load 104 (see FIG. 1) can be installed on the floor panel 102 with higher rigidity, and the weight of the load 104 can be distributed to the side member 150b etc. even while driving.

[0049] Fig. 4(b) is a cross-sectional view taken along line AA of bracket 118 in Fig. 4(a). As described above, frame horizontal frame portion 110 is provided with frame protrusion portion 132. Frame protrusion portion 132 is a pin-shaped member that protrudes downward from frame horizontal frame portion 110.

[0050] In this fixing structure 100, when the frame horizontal frame part 110 is placed on the bracket 118, the bracket sliding parts 126, 128 come into contact with the front and rear sides of the frame horizontal frame part 110. In this state, when the frame horizontal frame part 110 is lowered, the frame horizontal frame part 110 is guided by the inclined parts 144, 146 to slide down toward the bracket insertion part 130, and the frame protrusion part 132 is inserted into the bracket insertion part 130.

[0051] Referring again to Figure 3, paths L1 and L2 shown in Figure 3(b) are imaginary views of the path of the frame protrusion 132 when the frame horizontal frame portion 110 (see Figure 4(b)) is caused to slide along the inclined portions 144 and 146. Moreover, path L3 in Figure 3(a) is an imaginary view of the path of the frame protrusion 132 when the frame horizontal frame portion 110 is caused to slide in the vehicle width direction along the bracket sliding portions 126 and 128. The bracket insertion portion 130 is provided so as to be present on these paths L1-L3.

[0052] With the above configuration, simply by lowering the frame horizontal section 110 in Fig. 4(b) onto the bracket 118, its position in the front-to-rear direction is adjusted by the inclined sections 144, 146, and the frame protrusion section 132 is guided along paths L1, L2 (see Fig. 3(b)) and inserted into the bracket insertion section 130. Furthermore, when the frame horizontal section 110 is slid horizontally along the bracket sliding sections 126, 128, the frame protrusion section 132 is guided along path L3 (see Fig. 3(a)), whereby the installation position of the frame member 108 can be finely adjusted.

[0053] As described above, in this embodiment, by providing two bracket sliding portions 126, 128 and bringing the frame member 108 into contact with these bracket sliding portions 126, 128, it is possible to more easily adjust the position of the frame member 108.

[0054] In particular, the bracket sliding parts 126, 128 are arranged so that the inclined parts 144, 146 face each other in the fore-and-aft direction of the vehicle. As a result, when the frame horizontal frame part 110 is lowered between the inclined parts 144, 146, for example, the frame horizontal frame part 110 first comes into contact with the front inclined part 144 and moves down along it, and then the frame horizontal frame part 110 also comes into contact with the rear inclined part 146, thereby adjusting the fore-and-aft position of the frame horizontal frame part 110. In this way, in this embodiment, by using the multiple bracket sliding parts 126, 128 and the multiple inclined parts 144, 146, it is possible to easily install the frame member 108 in a desired position.

[0055] It is also possible to arrange a plurality of inclined portions such as inclined portions 144, 146 so as to face each other in the vehicle width direction. For example, it is also possible to arrange a bracket under the vertical frame portions 114, 116 extending in the front-rear direction of the frame member 110 (see FIG. 1), and to configure the respective inclined portions of the plurality of bracket sliding portions of the bracket to contact the vertical frame portions 114, 116 from both sides in the vehicle width direction. This configuration makes it possible to easily adjust the position of the frame member 108 in the vehicle width direction.

[0056] As described above, with the above configuration, the position of the cargo 104 (see FIG. 1) can be fine-tuned by a simple operation such as pushing it in the vehicle width direction after placing the frame horizontal section 110 on the floor panel 102 using the bracket 118 as a guide, making it possible to easily align it to the desired position.

[0057] 3(a), the path L3 extends in the vehicle width direction, but the direction in which the path L3 extends is not limited to the vehicle width direction, and it may extend in the front-rear direction, for example. Regardless of the direction in which the path L3 extends, it is sufficient that the bracket insertion portion 130 is set on the path L3, and the direction in which the path L3 extends can be appropriately set according to the direction in which the frame member 108 slides and slides along the bracket sliding portions 126 and 128.

[0058] As described above, the fixing structure 100 of this embodiment makes it possible to easily align the frame member 108 (see FIG. 1) on the floor panel 102. According to this embodiment, the work of assembling the load 104 to the floor panel 102 becomes easier, and it is possible to improve the assembling accuracy and reduce the work effort.

[0059] As shown in Fig. 4(b), the support surface portion 120 is separated from the floor panel 102 by the bracket legs 122, 124 (see Fig. 2(b)). This prevents the tip of the frame protrusion portion 132 from interfering with the floor panel 102 when the frame protrusion portion 132 is inserted into the bracket insertion portion 130, making it possible to join the frame member 108 (see Fig. 1) and the bracket 118 with high precision.

[0060] As shown in FIG. 3(a), reinforcing beads 134a, 134b, 136a, and 136b are provided at the bases of the bracket sliding portions 126 and 128.

[0061] The beads 134a, 134b are formed by bulging upward from the region extending from the bracket sliding portion 126 to the support surface portion 120 and the bracket legs 122, 124, and support their bases by extending from the bracket sliding portion 126 to both sides in the vehicle width direction. The beads 136a, 136b are formed by bulging upward from the region extending from the bracket sliding portion 128 to the support surface portion 120 and the bracket legs 122, 124, and support their bases by extending from the bracket sliding portion 128 to both sides in the vehicle width direction.

[0062] The beads 134a, 134b, 136a, 136b can increase the rigidity of the bracket sliding parts 126, 128, suppress deformation of the bracket sliding parts 126, 128, and improve the accuracy of assembly between the bracket 118 and the frame member 108 (see FIG. 1). In particular, by reinforcing the bracket sliding parts 126, 128 to which a load is input from the frame horizontal frame part 110 (see FIG. 4(b)) and suppressing deformation, it becomes possible to smoothly guide the frame horizontal frame part 110.

[0063] The bracket insertion portion 130 is formed to include a large diameter portion 130a having a large diameter and a small diameter portion 130b having a small diameter. The large diameter portion 130a is formed in an elliptical shape. The small diameter portion 130b has a smaller diameter than the large diameter portion 130a and is provided continuously with the end portion on the left side in the vehicle width direction of the large diameter portion 130a.

[0064] The frame protrusion 132 (see FIG. 4(b)) is inserted, for example, first into the large diameter portion 130a by lowering the frame horizontal frame portion 110 along the bracket sliding portions 126, 128. Then, the frame protrusion 132 is fitted into the small diameter portion 130b by sliding the frame horizontal frame portion 110 in the vehicle width direction along the bracket sliding portions 126, 128. This makes it possible to determine the position of the frame member 108 simply by lowering the frame horizontal frame portion 110 between the bracket sliding portions 126, 128 and further fine-tuning it by sliding it in the vehicle width direction. This configuration makes it possible to easily align the frame member 108 on the floor panel 102 and also to improve the assembly accuracy of the frame member 108 to the floor panel 102.

[0065] Although the preferred embodiment of the present invention has been described above with reference to the accompanying drawings, it goes without saying that the present invention is not limited to the above-described embodiment. It is clear that a person skilled in the art can think of various modifications or alterations within the scope of the claims, and it is understood that these also naturally belong to the technical scope of the present invention.
