DETAILED DESCRIPTION

[0029] In order to solve the risk of the cab shell being torn at the connection due to the relative torsional shaking between the heat-insulating pedal and the left and right cabs, and to enable the maintenance personnel to step directly on the engine during vehicle idling maintenance, this embodiment provides a suspended heat-insulating pedal 10, which is installed in a vehicle with left and right cabs, and the left and right cabs are split cabs, such as Figure 1 As shown, its left and right sides are connected to the left and right cabs respectively.

[0030] In this embodiment, the suspended heat-insulating pedal board 10 is located on the upper part of the engine and is connected to the vehicle body on both sides. It can isolate the heat emitted by the engine, improve the adverse effects of the heat on the upper equipment, and protect the upper equipment. At the same time, its suspended fixed structure can ensure that the pedal board is in a suspended state, avoiding the heat-insulating pedal board and the vehicle body from being torn when the left and right vehicle bodies shake and twist relative to each other.

[0031] Please refer to Figure 2 and Figure 3 , and can be combined with Figure 1 It is understood that the suspended heat-insulating pedal board 10 includes a pedal board assembly 11 and at least two suspended support assemblies 12. The opposite sides of the pedal board assembly 11 are respectively connected to the left and right cabs through the suspended support assemblies 12, and the pedal board assembly 11 is limited to be located above the engine.

[0032] Please refer to Figure 6 and Figure 7 The pedal assembly 11 includes a pedal body 21 and a heat-insulating layer 22 mounted below the pedal body 21. The large-area heat-insulating layer 22 ensures that the pedal assembly 11 has good thermal insulation. Furthermore, first oblong holes 211 are provided on opposite sides of the pedal body 21. These first oblong holes 211 are used to connect the pedal assembly 11 to the suspended support assembly 12.

[0033] Please refer to Figure 4 、 Figure 5 as well as Figures 8 to 11The suspension support assembly 12 includes a support 31, an upper shock-absorbing pad 32, a lower shock-absorbing pad 33, a bolt with a hole 34, a sleeve 35, a slotted nut 36, an upper washer 37, a second locking pin 38, and a lower washer 39. The support 31 includes a first transverse plate 311 and a second vertical plate 312. The second vertical plate 312 is connected to the first transverse plate 311. The first vertical plate is provided with a group of mounting holes 314 for connecting to the left and right cabs. The first transverse plate 311 is provided with a second oblong hole 313. It is defined that the length of the first oblong hole 211 and the length of the second oblong hole 313 are respectively arranged along the front-rear direction and the left-right direction of the vehicle, the hole bolt 34 passes through the upper washer 37, the sleeve 35, the lower washer 39 and the slotted nut 36 in sequence, the sleeve 35 passes through the first oblong hole 211 of the pedal body 21, the upper shock-absorbing pad 32, the second oblong hole 313 of the first cross plate 311 and the lower shock-absorbing pad 33 in sequence, the lower end surface of the sleeve 35 is flush with the lower end surface of the lower shock-absorbing pad 33, and the second locking pin 38 passes through the slot of the slotted nut 36 and the hole of the hole bolt 34.

[0034] The upper shock-absorbing pad 32 isolates the support 31 from the pedal assembly 11, preventing the support 31 and the insulated pedal assembly 11 from shaking relative to each other and causing sharp noises, thereby protecting the anti-corrosion coating. The lower shock-absorbing pad 33 isolates the lower washer 39 from the support 31, preventing the lower washer 39 and the support 31 from shaking relative to each other and causing sharp noises, thereby protecting the anti-corrosion coating. The sleeve 35 isolates the eyelet bolt 34 from the pedal assembly 11 and support 31, preventing the sharp noises caused by relative shaking and protecting the anti-corrosion coating.

[0035] In this embodiment, the second locking pin 38 cooperates with the slotted nut 36 and the eye bolt 34 to prevent the slotted nut 36 from falling off the eye bolt 34. In some embodiments, the eye bolt 34 is a hexagonal head screw eye bolt 34, and the slotted nut 36 is an I-type hexagonal slotted nut 36.

[0036] It should be noted that Figure 6 The length of the first oblong hole 211 is set along the width direction of the pedal body 21. Figure 1 The width direction of the middle pedal body 21 is the front-rear direction of the vehicle; on the other hand, combined with Figure 1 、 Figure 2 and Figure 11 As shown, the length of the second oblong hole 313 is arranged along the left-right direction of the vehicle; that is, the length of the first oblong hole 211 is along the front-to-back direction of the vehicle, and the length of the second oblong hole 313 is along the left-to-right direction of the vehicle, and the length direction of the first oblong hole 211 and the length direction of the second oblong hole 313 are perpendicular to each other. In another embodiment, the length of the first oblong hole 211 is along the left-to-right direction of the vehicle, and the length of the second oblong hole 313 is along the front-to-back direction of the vehicle.

[0037] The suspended heat-insulating pedal board 10 provided in this embodiment works in such a way that when the left and right cabs shake and twist relative to each other, the first oblong hole 211 and the second oblong hole 313 cooperate with the bolt lock pin connection in the suspended support assembly 12, so that the pedal board assembly 11 can be adaptively adjusted in the front and rear and left and right directions of the vehicle. The upper shock-absorbing pad 32 and the lower shock-absorbing pad 33 in the suspended support assembly 12 cooperate with other structural parts to realize a suspended connection, so that the pedal board assembly 11 can be adaptively adjusted in the height direction of the vehicle. On the whole, the suspended structure can ensure that the heat-insulating pedal board is in a suspended state, and the heat-insulating pedal board is well fixed on the left and right vehicle bodies, so as to avoid the suspended heat-insulating pedal board 10 being torn due to the relative shaking and twisting of the left and right vehicle bodies, and ensure that the pedal board assembly 11 does not shake relative to the suspended support assembly 12. In addition, the pedal body 21 provides a pedaling support position for personnel, and the thermal insulation layer 22 installed under the pedal body 21 is used for thermal insulation, specifically isolating the heat of the engine from the upper mounted equipment, avoiding damage to the upper mounted equipment, and ensuring the safety of maintenance personnel when stepping, making it convenient to repair the vehicle.

[0038] In some embodiments, the combined thickness of the pedal assembly 11, upper shock absorber 32, first cross plate 311, and lower shock absorber 33 is equal to the length of the sleeve 35. This ensures that after the slotted nut 36 is tightened, only the sleeve 35 is compressed. Specifically, the sleeve 35 abuts against the upper washer 37 at the top and the lower washer 39 at the bottom, while the upper and lower shock absorbers 32, 33 are not compressed. This ensures that the pedal assembly 11, upper shock absorber 32, support 31, and lower shock absorber 33 do not shake or make abnormal noise in the vertical direction. Furthermore, when the vehicle body shakes or twists, the upper and lower shock absorbers 32, 33 have a certain degree of elastic deformation, allowing the pedal assembly 11 to shake relative to the support 31 without tearing the vehicle body.

[0039] In some embodiments, see Figure 5 and Figure 7 The pedal body 21 includes a frame 212 as a frame and a skin 213 covering the frame 212, and the heat insulation layer 22 is installed under the skin 213. In this way, the overall strength and rigidity of the suspended heat-insulating pedal 10 are ensured, and the safety of the personnel is guaranteed.

[0040] Comparison reference Figure 5 and Figure 10 An installation space 40 is formed between the upper washer 37 and the upper shock-absorbing pad 32, and a portion of the pedal body 21 is placed in the installation space 40; in the scheme where the pedal body 21 includes a skeleton 212 and a skin 213, a portion of the skeleton 212 is located in the installation space 40 to smoothly realize the connection between the pedal assembly 11 and the suspension support assembly 12.

[0041] In some embodiments, see Figure 6 and Figure 7 The thermal insulation layer 22 is connected to the pedal body 21 through multiple fixing units 20. The fixing unit 20 includes a pressure plate 23, a pin 24 and a first locking pin 25. The pin 24 passes through the skin 213, the thermal insulation layer 22 and the pressure plate 23 in sequence. The first locking pin 25 is fixed on the pin 24 through the hole at the end of the pin 24. The first locking pin 25 contacts the pressure plate 23, limiting the pressure plate 23 to prevent the pressure plate 23 from falling off, thereby realizing a limited connection between the skin 213 and the thermal insulation layer 22.

[0042] In some embodiments, in order to save costs, the pin 2424 directly adopts industry standard parts.

[0043] In some embodiments, the pin 24 is fixedly connected to the cover 213 of the pedal body 21 .

[0044] In some embodiments, in order to improve the overall strength of the pressing plate 23, please refer to Figure 7 The pressing plate 23 is provided with flanges along the circumference.

[0045] In some embodiments, see Figure 6 The heat insulation layer 22 is connected to the pedal body 21 through a plurality of fixing units 20 arranged at intervals along the circumference of the frame 212 and a fixing unit 20 located at the center of the frame 212. The frame 212 is arranged in a rectangular shape, and fixing units 20 are arranged at the four corners of the frame 212. Figure 6 In the figure, each side of the skeleton 212 corresponds to three fixing units 20, two of the three fixing units 20 are close to the corners of the rectangle, and the other one is located in the middle of the side, so that the insulation layer 22 is connected to the pedal body 21 through a total of nine fixing units 20.

[0046] In some embodiments, the number of holes in the mounting hole group 314 is not less than 3, with no less than 2 holes in the up and down directions and no less than 2 holes in the left and right directions, ensuring the connection strength between the suspended heat-insulating pedal board 10 and the vehicle body.

[0047] In some embodiments, in order to enhance the structural strength of the support 31, please refer to Figure 8 and Figure 11 The support 31 further includes two triangular side panels 315, which are spaced apart from each other. The two triangular side panels 315 are respectively arranged on opposite sides of the first horizontal panel 311, that is, the two triangular side panels 315 are respectively arranged on opposite sides of the second vertical panel 312. One side of the triangular side panel 315 is connected to the first horizontal panel 311, and the other side is connected to the second vertical panel 312. Figure 11Under the condition that there are two right-angled sides, one of the right-angled sides is connected to the first horizontal plate 311, and the other right-angled side is connected to the second vertical plate 312.

[0048] In some embodiments, see Figure 1 and Figure 2 The pedal assembly 11 is arranged in a rectangular shape, and the two wide sides of the pedal assembly 11 are respectively connected to the left and right cabs through two suspension support assemblies 12, and the suspension support assembly 12 is close to the corner of the pedal assembly 11.

[0049] This embodiment also provides a vehicle, including left and right cabs and the above-mentioned suspended heat-insulating pedal 10 for connecting the left and right cabs. The suspended heat-insulating pedal 10 is located on the upper part of the engine, which not only protects the upper equipment, but also meets the pedaling requirements of maintenance personnel to repair the vehicle. The suspended connection structure solves the risk of the cab shell at the connection being torn due to relative torsional shaking between the heat-insulating pedal and the left and right cabs.
