The connecting rod mechanism includes an active connecting rod assembly and a driven connecting rod assembly arranged at intervals, and the driven connecting rod assembly includes a driven connecting rod 7 rotatably provided on a sleeve 9, and the sleeve 9 is provided on the vehicle body and is used for the exhaust pipe 1 to pass through.

[0048] The welcome pedal assembly of this embodiment sets the welcome pedal 2 on the vehicle body through a connecting rod mechanism, so that the welcome pedal can be switched between the unfolded state and the stowed state, which can improve the convenience of passengers getting on and off the vehicle. The sleeve 9 for the exhaust pipe 1 to pass through can not only make the exhaust pipe 1 avoid the components inside the connecting rod mechanism better, but also provide a larger layout space for the components inside. At the same time, there is no need to flatten the exhaust pipe 1, so as to solve the problem of increased fuel consumption caused by increased back pressure of the exhaust system due to flattening of the exhaust pipe 1, and also improve the rationality of the layout of the exhaust pipe 1 and the components of the whole vehicle.

[0049] Based on the above overall introduction, an exemplary structure of the welcome pedal assembly of this embodiment is referred to as follows: Figures 1 to 3 As shown in the figure, and for the convenience of explaining this embodiment, the exhaust pipe 1 and the welcome pedal 2 and the connection structure diagram between the two are schematically shown in the figure.

Thus, under the drive of the driving unit 10, the welcome pedal 2 can be driven to switch between the expanded state and the retracted state in a horizontal posture, and the function of the welcome pedal 2 for stepping can also be better guaranteed. At the same time, the driving unit 10 is arranged on the vehicle body, and the driving shaft of the driving unit 10 is connected to the hinge shaft of the active connecting rod 5. Specifically, the driving unit 10 can adopt a motor or a cylinder that outputs rotational power.

The sleeve 9, i.e., the hinge axis between the second transmission connecting rod 8 and the vehicle body, is arranged between the two side plates. Such an arrangement can improve the arrangement stability of the sleeve 9 and the hinge axis, thereby improving the force transmission stability of the driven connecting rod assembly.

[0056] It should be noted that in order to obtain better use effect, such as Figure 1 As shown in FIG. 1 , as a preferred embodiment, the first bracket 3 and the second bracket 4 of this embodiment simultaneously adopt the above structure. Of course, in addition to the first bracket 3 Figure 5 The structure shown in FIG. 1 may also adopt other structures. Similarly, the second bracket 4 may adopt Figure 6 Although the structure shown in FIG. 1 is different from that shown in FIG.

[0057] In addition, in order to facilitate the connection between the welcome pedal 2 and the active connecting rod assembly and the driven connecting rod assembly, as a preferred embodiment, Figure 7 As shown in , the welcome pedal 2 of this embodiment includes a pedal body 201 and connecting parts 202 provided at both ends of the length direction of the pedal body 201. In addition, each connecting part 202 protrudes to one side of the pedal body 201 and has two connecting plates arranged oppositely, and the active connecting rod assembly and the driven connecting rod assembly are respectively connected to the connecting parts 202 at the corresponding ends. Among them, the specific structure of the pedal body 201 can refer to the prior art, and it is generally provided with anti-slip protrusions.

The driven connecting rod 7 and the second transmission connecting rod 8 are located between the two connecting plates of the connecting part 202 at the left end, and are rotatably connected to the two side plates through the rotating shaft.

[0059] Based on the above overall description, when the welcome pedal 2 of this embodiment is in use, the vehicle control unit can control the driving unit 10 to start, so as to drive the active link 5 to rotate, thereby driving the first transmission link 6, the driven link 7 and the second transmission link 8 to move, so that the welcome pedal 2 Figure 1 The expanded state shown and Figure 3 Moreover, the welcome pedal assembly of this embodiment, by providing the sleeve 9 for the exhaust pipe 1 to pass through, does not need to flatten the exhaust pipe 1 to avoid the surrounding parts, thereby solving the problem of increased exhaust back pressure, and at the same time, does not affect the extension and retraction of the welcome pedal 2, and can also improve the rationality of the layout space of the whole vehicle.

[0060] In addition, the present embodiment also relates to a vehicle, which is provided with the above-mentioned welcome pedal assembly, and the exhaust pipe of the vehicle passes through the sleeve 9 .

[0061] Continue to refer to Figures 1 to 3 As shown in the figure, the exhaust pipe 1 of this embodiment is connected to the engine, and is the same as the prior art in that it is mounted on the vehicle body through a rubber hanger. The structure of the rubber hanger can refer to the prior art, and generally includes a rubber hanger, an upper hanger hook, a lower hanger hook and a limit hanger hook, and the upper hanger hook and the lower hanger hook are respectively connected to the upper and lower ends of the rubber hanger, and one end of the limit hanger hook is fixedly connected to the upper hanger hook, and the other end extends into the central through hole of the rubber hanger and is located between the upper limit protrusion and the lower limit protrusion.

Such a configuration not only facilitates the connection of the first part 101 with other components, but also enables the second part 102 to better avoid other components, so as to facilitate the arrangement of other components and the arrangement of the second part 102 on the vehicle body.

[0063] In addition, as a further embodiment, a battery pack is provided at the bottom of the vehicle, and the second part 102 is provided corresponding to the battery pack and is provided on the side of the battery pack close to the outside of the vehicle. This design allows the second part 102 to avoid the battery pack better, allowing the battery pack to have a better volume, thereby improving the vehicle's endurance. The structure of the battery pack and its installation structure can refer to the prior art and will not be repeated here.

[0064] The vehicle of this embodiment combines the exhaust pipe 1 with the welcome pedal 2 and adds a sleeve 9 in the connecting rod mechanism of the welcome pedal 2 so that the exhaust pipe 1 passes through the sleeve 9. This can improve the utilization rate of the layout space of the entire vehicle and avoid the problem of increased exhaust back pressure caused by the exhaust pipe 1 being flattened to avoid surrounding parts. At the same time, it does not affect the extension and retraction of the welcome pedal 2, and can also improve the rationality of the layout space of the entire vehicle.
