[0031] The specific implementation of the present utility model is described below in conjunction with the accompanying drawings.

[0032] like Figure 1 and Figure 2 As shown, an inlaid pedal structure of this embodiment includes a ferry assembly 1, and supports 2 are respectively installed at both ends of the ferry assembly 1, and vehicle end return assemblies are installed on the outer sides of the supports 2;

[0033] The structure of the single-group vehicle-end return assembly is as follows: it includes a leaf spring seat 6 installed on the corresponding vehicle body, and a leaf spring 5 is pressed between the leaf spring seat 6 and the support 2; the middle part of the leaf spring 5 is fixed on the leaf spring seat 6, and the two ends of the leaf spring 5 abut against the support 2.

[0034] In this embodiment, the leaf spring 5 is press-fitted between the leaf spring seat 6 and the support 2, and the leaf spring 5 applies a pre-tightening force to the ferry assembly 1 through the support 2, so that the ferry assembly 1 is restored to its initial state after being subjected to the force.

[0035] The leaf spring 5 in this embodiment is in a C-shaped structure as a whole. The leaf spring seat 6 is arranged in the middle of the outer side of the C-shaped structure. The end of the C-shaped structure is bent and extended to form an abutment portion in contact with the support 2.

[0036] Pull rings 24 are installed at intervals on the side of the support 2 facing the leaf spring seat 6 , and a pull cable 4 is installed between the pull ring 24 and the leaf spring seat 6 .

[0037] In this embodiment, the arrangement of the cable 4 between the support 2 and the leaf spring seat 6 effectively prevents the support 2 from being separated from the leaf spring 5 and the leaf spring seat 6 , thereby effectively ensuring reliable contact between the leaf spring 5 and the support 2 .

[0038] like Figure 3 As shown, horizontal plates 61 are installed at intervals above and below the side of the leaf spring seat 6 facing the support 2, and the cable 4 is installed between one horizontal plate 61 or two horizontal plates 61 and the pull ring 24; a vertical plate 62 is installed between the two horizontal plates 61, and the leaf spring 5 passes through the interval between the vertical plate 62 and the leaf spring seat 6.

[0039] In this embodiment, the cable 4 is installed on the leaf spring seat 6 via the horizontal plate 61 ; in actual operation, a through hole for the end of the cable 4 to pass through can be opened on the horizontal plate 61 to facilitate the installation of the cable 4 .

[0040] exist Figure 3 In the illustrated embodiment, the cables 4 facing away from each other and facing the two pull rings 24 on the support 2 are installed on the same horizontal plate 61, and the assembled structure is symmetrical, which effectively ensures the stability and consistency of the overall structure.

[0041] In this embodiment, the leaf spring 5 is inserted between the vertical plate 62 and the leaf spring seat 6 and the leaf spring 5 is limited by combining the upper and lower horizontal plates 61 , thereby effectively ensuring the installation reliability of the leaf spring 5 on the leaf spring seat 6 .

[0042] A fastener is locked through the vertical plate 62 toward the leaf spring 5 , thereby further ensuring that the leaf spring 5 is stably and fixedly installed relative to the leaf spring seat 6 .

[0043] like Figure 4 As shown, one end of the ferry assembly 1 is extended at intervals to form a lug 11, and a pair of lugs 21 corresponding to the lug 11 are extended on the support 2. The lug 11 is inserted between the pair of lugs 21, and a rotating structure is installed through the lugs 11 and the lugs 21, forming a rotating installation between one end of the ferry assembly 1 and the corresponding support 2.

[0044] In this embodiment, the ferry assembly 1 is rotatably mounted with the lug 21 of the corresponding support 2 via the lug 11 on the left beam 12 .

[0045] The other end of the ferry assembly 1 is provided with a lock core 16 on both sides, and a support plate 22 for the lock core 16 to be mounted on the corresponding support 2, and the lock core 16 is assembled into the lock hole on the support plate 22 to achieve assembly.

[0046] In this embodiment, the ferry plate assembly 1 is assembled with the support plate 22 of the corresponding support 2 through the lock core 16 on the right beam 17; since the lock core 16 can be retracted or extended relative to the right beam 17, it is locked with the support plate 22 when extended and unlocked when locked, which is not only convenient for assembly and disassembly, but also does not affect the relative rotation of the ferry plate assembly 1 through the assembly between the lock core 16 and the support plate 22 under external force during use.

[0047] A support block 23 extending from the support 2 located on the inner side of the support plate 22 is configured to conform to the end of the ferry assembly 1 .

[0048] In this embodiment, while the ferry assembly 1 and the support 2 are rotationally assembled via the lock core 16 and the support plate 22, the ferry assembly 1 is also supported at the contact point via the contoured support block 23, effectively reducing the force at the lock core 16 without affecting its relative rotation when subjected to external force.

[0049] The structure of the ferry assembly 1 is as follows: it includes a left beam 12 and a right beam 17 arranged in parallel at intervals, and the ends of the left beam 12 and the right beam 17 are respectively and jointly rotatably mounted with side beams 15 to form a quadrilateral structure; it also includes a plurality of ferry plates closely arranged along the width direction, and the two ends of a single ferry plate are respectively abutted against the pins 14 of the two side beams 15.

[0050] In this embodiment, the ferry assembly 1 is formed into a quadrilateral structure through the left beam 12, the right beam 17 and the two side beams 15, so that the ferry can move relative to each other when the vehicle passes through a curve, ensuring that passengers can pass safely and smoothly.

[0051] Each ferry plate end is abutted against the corresponding pin shaft 14 of the side beam 15 to form a rotating assembly structure to meet the required deflection movement.

[0052] The ends of the left beam 12 and the right beam 17 are respectively provided with rotating members 13 , and the ends of the side beam 15 are provided with holes for the rotating members 13 to be rotatably mounted.

[0053] In this embodiment, the structure of the rotating part 13 can be: a sleeve is welded on the left beam 12 and the right beam 17, a nut structure is welded at the lower end of the hole of the side beam 15, the sleeve is assembled into the side beam 15, and then the fastener is locked toward the nut structure after passing through the sleeve to realize the rotational installation between the side beam 15 and the left beam 12 or the right beam 17.

[0054] Of course, in actual use, the rotating member 13 may also be other structures that can realize the rotational assembly between the side beam 15 and the left beam 12 or the right beam 17 .

[0055] like Figure 5 As shown, the ferry plate includes a ferry plate 18 and a ferry plate 19 arranged at intervals. The cross-sections of the ferry plate 18 and the ferry plate 19 are both I-shaped structures. The height dimension of the ferry plate 18 is smaller than the height dimension of the ferry plate 19. The edge of the ferry plate 18 is connected and fitted into the ferry plate 19 to achieve a tight fit between adjacent ferry plates. The end of a single ferry plate is provided with an inwardly concave arc structure 181, which is a rotationally fitted structure between the inwardly concave arc structure 181 and the pin shaft 14.

[0056] In this embodiment, the pin shaft 14 may be welded to the side beam 15 .

[0057] In this embodiment, the ferry board 18 and the ferry board 19 can be set to different materials, such as aluminum profiles and plastics, according to actual conditions, which can not only achieve close fitting of adjacent ferry boards, but also does not affect the smooth relative movement between adjacent ferry boards under the action of external forces.

[0058] Rollers 3 are respectively installed at both ends of the support 2. The rollers 3 are arranged vertically axially, and the outer circumferential surfaces of the rollers 3 abut against the vehicle body. The rollers 3 limit the support 2 and the ferry assembly 1 to perform linear motion as a whole.

[0059] like Figure 6 As shown, it also includes a pedal assembly 10, which is arranged in pairs on both sides of the ferry assembly 1, and the pedal assemblies 10 on both sides are freely overlapped on the ferry assembly 1 respectively.

[0060] The pedal assembly 10 is fixed on the vehicle body, and the vehicle end return assembly is shielded by the pedal assembly 10, effectively ensuring the safe passage of passengers.

[0061] The pedal assembly 10 in this embodiment can adopt the existing general pedal assembly structure, for example, it can be composed of aluminum alloy plates, stainless steel hinges, wear strips, etc., to cover the end of the ferry assembly 1 and the vehicle end return assembly.

[0062] When in use, both ends of the ferry assembly 1 are installed on adjacent vehicle bodies. When in a curved state, the quadrilateral structure of the ferry assembly 1 is deformed accordingly under force, and can maintain uniform arrangement between the ferry boards during deformation; when the ferry assembly 1 is in an overheight working condition near a vehicle, due to the rotational assembly between the two ends of the ferry assembly 1 and the support 2, the ferry assembly 1 can swing up and down adaptively with the height difference of the vehicle body.

[0063] The utility model satisfies various functional movements of the bus under specified technical conditions and road conditions, especially has good small curve passing ability; and the overall structure is compact, the layout is simplified, the volume is small, and the installation space is effectively reduced.

[0064] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0065] The above description is an explanation of the utility model, not a limitation of the utility model. The scope of the utility model is defined by the claims. Any form of modification can be made within the protection scope of the utility model.
