Description

Technical Field

[0001] The utility model relates to the technical field of vehicles, in particular to a vehicle platform fixing structure and a vehicle with the same. Background Art

[0002] The vehicle walkway fixing structure in the related technology is installed above the longitudinal beam, and the walkway plate needs to be fixedly connected to the wing plate on the longitudinal beam through a connecting bracket. Since the connecting bracket is located at both ends of the walkway plate, there is a lack of limit between the walkway plate and the longitudinal beam when installing the walkway plate, and the assembly is difficult. After the walkway plate is installed, sliding is likely to occur between the connecting bracket and the wing plate on the longitudinal beam, thereby generating metal friction noise. Utility Model Content

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, one purpose of the utility model is to provide a vehicle platform fixing structure, which has the advantages of enhancing structural stability, eliminating noise and facilitating installation.

[0004] The utility model also provides a vehicle with a vehicle platform fixing structure.

[0005] To achieve the above-mentioned purpose, according to an embodiment of the utility model, a vehicle walkway fixing structure is proposed, including: a walkway plate, the bottoms of both ends of the walkway plate are suitable for supporting the upper wing plate of the longitudinal beam, and long holes are constructed on both sides of the walkway plate, and the long holes extend in a direction perpendicular to the upper wing plate of the longitudinal beam; a connecting bracket, the connecting bracket includes an upper supporting edge, a lower supporting edge and a connecting portion, the upper supporting edge is constructed with an upper hook, the upper hook passes through the long hole upward and engages with the edge of the long hole, the upper supporting edge supports and is installed on the bottom of the walkway plate, the lower supporting edge is supported on the bottom of the upper wing plate of the longitudinal beam, the edge of the lower supporting edge is constructed with a flange extending upward, the flange is stopped at the inner side of the upper wing plate of the longitudinal beam, and the connecting portion is connected between the upper supporting edge and the lower supporting edge.

[0006] According to the vehicle walkway fixing structure of the embodiment of the utility model, the bottom of both ends of the walkway is supported on the wing plate of the longitudinal beam, and the connecting bracket forms a stable connection structure through the upper supporting edge, the lower supporting edge and the connecting part. The upper hook of the upper supporting edge is engaged with the long holes on both sides of the walkway, and the position of the upper hook is adjustable within the range of the long hole, so as to fix the walkway in a suitable position. The connecting bracket is tightly connected with the walkway and the wing plate of the longitudinal beam, and the edge of the lower supporting edge is constructed with a flange, which is folded upward and stopped on the inner side of the wing plate of the longitudinal beam on the left and right sides. The wing plate of the longitudinal beam is limited to the flanges on both sides, and the connecting brackets on both sides are fixed to the walkway, thereby limiting the displacement of the wing plate of the longitudinal beam, and providing a limit for the installation of the walkway. The upper hook of the connecting bracket passes through the long hole of the walkway and is engaged, and the lower supporting edge is supported below the wing plate of the longitudinal beam, so that the hook can limit the upper and lower directions of the walkway. The flange is stopped at the inner side of the wing plate on the longitudinal beam. This connection method is relatively simple, so that the connecting bracket is tightly combined with the walkway and the wing plate on the longitudinal beam, and it is convenient to disassemble and install, saving installation time and improving work efficiency.

[0007] In addition, by using the flange structure on the connecting bracket, the flange is stopped on the inner side of the wing plate on the longitudinal beam, which can effectively reduce the back and forth friction and movement of the connecting bracket 200 during driving, thereby reducing noise generation and improving riding comfort. By supporting the flange on the inner side of the wing plate on the longitudinal beam, the connecting part does not need to bear the force in the left and right directions, reducing the stress between the connecting part and the upper support edge and the lower support edge, and the force of the connecting bracket is more reasonable and reliable, and the structural strength is high.

[0008] Therefore, the vehicle platform fixing structure according to the embodiment of the utility model has the advantages of low assembly difficulty, reduced noise, and improved structural strength.

[0009] According to some specific embodiments of the present utility model, the upper hook is located on a side of the upper supporting edge away from the connecting portion, and the upper hook is wider than a width of the long hole.

[0032] The vehicle platform fixing structure 1 according to an embodiment of the present utility model is described below with reference to the accompanying drawings.

[0033] like Figure 1-Figure 4 As shown, the vehicle walkway fixing structure 1 according to the embodiment of the utility model includes a walkway plate 100 and a connecting bracket 200 .

[0034] The bottom of both ends of the walkway 100 is suitable for supporting the longitudinal beam upper wing plate 10. Long holes 110 are configured on both sides of the walkway 100. The long holes 110 extend in a direction perpendicular to the longitudinal beam upper wing plate 10. The connecting bracket 200 includes an upper supporting edge 210, a lower supporting edge 220 and a connecting portion 230. The upper supporting edge 210 is configured with an upper hook 211, which passes through the long hole upward and is engaged with the edge of the long hole 110. The upper supporting edge 210 supports and is installed on the bottom of the walkway 100. The lower supporting edge 220 is supported on the bottom of the longitudinal beam upper wing plate 10. The edge of the lower supporting edge 220 is configured with a flange 203 extending upward. The flange 203 stops at the inner side of the longitudinal beam upper wing plate 10. The connecting portion 230 is connected between the upper supporting edge 210 and the lower supporting edge 220.

[0035] For example, the walkway 100 and the upper wing plate 10 of the longitudinal beam are placed vertically and located above the longitudinal beam. The connecting bracket 200 fixedly connects the walkway 100 and the upper wing plate 10 of the longitudinal beam. The long hole 110 extends along the length of the walkway 100. The hook 2221 first extends in the direction of the long hole 110, and then the connecting bracket 200 is rotated 90 degrees to make the hook 221 engage with the edges on both sides of the long hole 110. The upper hook 211 can move back and forth within the length of the long hole 110, thereby adjusting the installation position of the connecting bracket 200. The upper supporting edge 210 fits tightly with the walkway 100, and the connecting bracket 200 can be a metal bending structure. The upper supporting edge 210 and the lower supporting edge 220 extend in opposite directions respectively. The upper supporting edge 210, the connecting portion 230 and the lower supporting edge 220 together form a stepped structure. The upper supporting edge is installed with the walkway 100 through the upper hook 211, and the upper hook 211 can be further fixed with the walkway 100 through fasteners. The upper supporting edge 210 is supported at the bottom of the walkway, and the lower supporting edge 220 is supported at the bottom of the upper wing plate 10 of the longitudinal beam.

[0036] According to the vehicle walkway fixing structure 1 of the embodiment of the utility model, the bottoms of both ends of the walkway 100 are supported on the longitudinal beam upper wing plate 10, and the connecting bracket 200 forms a stable connection structure through the upper supporting edge 210, the lower supporting edge 220 and the connecting portion 230. The upper hooks 211 of the upper supporting edge 210 are engaged with the long holes 110 on both sides of the walkway 100, and the upper hooks 211 are adjustable in position within the range of the long holes 110, so as to fix the walkway 100 in a suitable position. The connecting bracket 200 is tightly connected to the walkway 100 and the longitudinal beam upper wing plate 10. The edge (e.g., front and rear edge) of the lower support edge 220 is constructed with a flange 203. The flange 203 is folded upward and stopped at the inner side of the longitudinal beam upper wing plate 10 on the left and right sides. The longitudinal beam upper wing plate 10 is restricted by the flanges 203 on both sides, and the connecting brackets 200 on both sides are fixed to the walkway 100, thereby limiting the displacement of the longitudinal beam upper wing plate 10, providing a limit for the installation of the walkway 100. The upper hook 211 of the connecting bracket 200 passes through the long hole 110 of the walkway 100 and is engaged, and the lower support edge is supported below the longitudinal beam upper wing plate, so that the hook 211 can limit the walkway 100 in the up and down directions. The flange 203 stops at the inner side of the longitudinal beam upper wing plate 10. This connection method is relatively simple, so that the connecting bracket 200 is tightly combined with the walkway 100 and the longitudinal beam upper wing plate 10, and is convenient for disassembly and installation, saving installation time and improving work efficiency.

[0037] In addition, the flange 203 structure on the connecting bracket 200 is stopped on the inner side of the longitudinal beam upper wing plate 10, which can effectively reduce the back and forth friction and movement of the connecting bracket 200 during driving, thereby reducing noise generation and improving riding comfort. By supporting the flange on the inner side of the longitudinal beam upper wing plate 10, the connecting part 230 does not need to bear the force in the left and right directions, reducing the stress between the connecting part 230 and the upper support edge 210 and the lower support edge 220, and the force of the connecting bracket 200 is more reasonable and reliable, and the structural strength is high.

[0038] Therefore, the vehicle platform fixing structure 1 according to the embodiment of the utility model has the advantages of low assembly difficulty, reduced noise, and improved structural strength.

[0039] In some specific embodiments of the present invention, Figure 4 As shown, the upper hook 211 is located on a side of the upper supporting edge 210 away from the connecting portion 230 , and the upper hook 211 is wider than the width of the long hole 110 .

[0040] Since the upper hook 211 is located on one side of the upper support edge 210 and is wider than the width of the long hole 110, it can ensure that the connection between the walkway 100 and the connecting bracket 200 is more firm and stable. The upper hook 211 is wider than the width of the long hole 110, which can effectively prevent the walkway 100 and the connecting bracket 200 from being misaligned or sliding, and avoid the walkway 100 from loosening or falling off due to vibration or bumps during the operation of the vehicle, thereby improving the stability of the walkway 100, ensuring the safe driving of the vehicle, and also extending the service life of the walkway 100 and the connecting bracket 200.

[0041] In addition, the connection mode between the upper hook 211 and the slot 110 makes it more convenient to install and remove the platform 100. Through this structure, a relatively simple installation and removal mode can be adopted, which improves the convenience and efficiency of operation and saves the time and labor cost of installation and maintenance.

[0042] In some specific embodiments of the present invention, Figure 2-Figure 4 As shown, the upper hook 211 includes an extension portion 201 and a clamping edge 202. The extension portion 201 is connected to the upper support edge 210 and bent upward, and the extension portion 201 is inserted into the long hole 110. The clamping edge 202 is located on both sides of the extension portion 201 in the width direction to be clamped on the two side edges of the long hole 110.

[0043] The clamping edge 202 of the upper clamping hook 211 is located on both sides of the extension part 201 in the width direction, and is fixed with the edges of both sides of the long hole 110. The width of the clamping edge 202 is greater than the width of the long hole 110. The clamping edge 202 can move back and forth within the length of the long hole 110 to adapt to walkways 100 of different sizes or installation positions, ensuring that the walkway 100 is fixed in a suitable position to be connected with the upper wing plate 10 of the longitudinal beam, thereby improving the accuracy and stability of the connection.

[0044] The extension portion 201 is firmly connected to the upper support edge 210 , and can increase the support area by bending upward, thereby improving the fixing stability and ensuring that the walkway 100 will not fall off or move easily.

[0045] In some specific embodiments of the present invention, Figure 2-Figure 4 As shown, the lower support edge 220 includes an upper step portion 221 and a lower step portion 222. The lower step portion 222 is connected to a side of the upper step portion 221 away from the connecting portion 230 and is located below the upper step portion 221. The flange 203 is formed on the upper step portion 221.

[0046] The upper step portion 221 and the lower step portion 222 are transitionally connected. For the longitudinal beam of the structure of the two-layer longitudinal beam upper wing plate 10, the upper step portion 221 is supported on the upper layer of the longitudinal beam upper wing plate 10, and the lower step portion 223 is supported on the lower layer of the longitudinal beam upper wing plate 10, which can provide a stable support for the longitudinal beam upper wing plate 10. The connection between the upper step portion 221 and the lower step portion 222 can increase the contact area with the longitudinal beam upper wing plate 10, fit closely with the longitudinal beam upper wing plate 10, increase the stability of the connection between the connecting bracket 200 and the longitudinal beam upper wing plate 10, and ensure that the longitudinal beam upper wing plate 10 is not easy to shake or loosen during operation.

[0047] At the same time, the angle between the upper step portion 221 and the lower step portion 222 is an obtuse angle, which reduces the stress concentration on the lower support edge 220 and improves the service life and reliability of the connecting bracket 100 .

[0048] In some specific embodiments of the present invention, Figure 2-Figure 4 As shown, a welding nut 223 corresponding to the position of the long hole 110 is constructed at the bottom of the lower supporting edge 220 , and a fastener is passed through the long hole 110 of the walkway 100 to install the connecting bracket 200 .

[0049] The structure of the welding nut 223 can facilitate the installation of the walkway 100 and the connecting bracket 200 without adding bolts or nuts. The fastener is inserted into the welding nut 223 through the long hole 110, and the connecting bracket can be quickly and conveniently fixed, which simplifies the installation process and improves work efficiency. Similarly, the structure of the welding nut 223 avoids the need for additional bolts, nuts and other additional parts, which can save material costs. In addition, the use of welding nuts also reduces the time and cost required for regular inspection and replacement of fasteners, reducing maintenance costs.

[0050] The structure of the welded nut 223 can increase the connection strength between the fastener and the walkway 100 and the connecting bracket 200. The welded nut can be more firmly fixed to the bottom of the connecting bracket 200, effectively preventing the nut from loosening or falling off, and improving the fixing strength and stability of the vehicle walkway fixing structure 1.

[0051] In some specific embodiments of the present invention, Figure 2-Figure 4As shown, the flange 203 is located at the front and rear sides of the lower support edge 220. Compared with the connection bracket in the prior art, the connection bracket 200 in the embodiment of the utility model can not only limit the displacement of the longitudinal beam upper wing plate 10 in the Y direction, but also limit the displacement of the longitudinal beam upper wing plate 10 in the upper and lower spaces, ensuring that the walkway 100 is firmly connected to the longitudinal beam upper wing plate 10 at a fixed position. By constructing the flange 203 structure on the front and rear sides of the lower support edge 220, the positions of the walkway 100 and the longitudinal beam upper wing plate 10 are restricted, preventing them from unnecessary displacement or shaking during the driving of the vehicle, maintaining the overall stability of the overall structure, and at the same time reducing the relative displacement between the walkway 100 and the longitudinal beam upper wing plate 10, increasing the reliability of the connection, and improving the safety of driving.

[0052] In some specific embodiments of the present invention, Figure 2-Figure 4 As shown, the upper support edge 210 and the lower support edge 220 are arranged in parallel, the angle between the connecting portion 230 and the upper support edge 210 is an obtuse angle, and the angle between the connecting portion 230 and the lower support edge 220 is an obtuse angle.

[0053] The obtuse angle structure can reduce the vertical stress and lateral stress between the connecting portion 230 and the upper supporting edge 210 and the lower supporting edge 220. Compared with the sharp angle connection, the angle formed by the obtuse angle can distribute the stress more evenly, reduce the distortion and pressure of each component during use, and help extend the service life of the connecting bracket 200.

[0054] The obtuse-angle structural connection method can also reduce the transmission of external vibrations to the upper support edge 210 and the lower support edge 220 during use, reduce the transmission of vibrations in the connecting portion 230, and alleviate the impact of vibrations on the connecting bracket 200, which not only extends the service life of the connecting bracket 200, but also improves the stability of the vehicle during driving.

[0055] In some specific embodiments of the present invention, Figure 1 As shown, the two side edges of the walkway 100 are constructed with lower supporting flanges 101 , and the lower supporting flanges 101 are suitable for supporting the upper surface of the longitudinal beam upper wing plate 10 .

[0056] The lower support flange 101 can provide additional support area, stop at the upper surface of the longitudinal beam upper wing plate 10, increase the contact area between the walkway 10 and the longitudinal beam upper wing plate 10, improve the support stability and load-bearing capacity, reduce the shaking and vibration of the walkway 100 during vehicle driving, and ensure the safety and comfort of passengers.

[0057] At the same time, through the connection between the lower support flange 101 and the upper wing plate 10 of the longitudinal beam, the firmness and stability of the connection between the two can be increased, and a damping rubber plate is added between the lower support flange 101 and the upper wing plate 10 of the longitudinal beam to effectively reduce the vibration and friction at the connection and achieve a noise reduction effect.

[0058] In some specific embodiments of the present invention, Figure 1 As shown, a concave portion extending in the length direction is formed on the upper surface of the walkway 100, a convex portion 102 is formed on the back of the concave portion, and a long hole 110 is formed at corresponding positions of the concave portion and the convex portion 102. The design of the concave portion and the convex portion on the back can increase the overall structural strength of the walkway 100. The convex portion can increase the thickness of the walkway 100 to a certain extent, strengthen the strength and rigidity of the plate, and improve the bearing capacity and anti-deformation ability.
