[0061] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0062] The following describes, in conjunction with the accompanying drawings, an embodiment of the retractable pedal device and a vehicle device having the same.

[0063] like Figures 1 to 4 As shown, the retractable pedal device 100 of this embodiment includes a mounting bracket 1, a drive shaft 2, a pedal 3, a first support arm assembly 4, and a second support arm assembly 5. The retractable pedal device 100 of this embodiment can be installed on a vehicle, for example, at the bottom of the vehicle body and near the lower edge of the side door or tailgate, to assist passengers in getting in and out of the vehicle. Of course, the retractable pedal device 100 can also be applied to other scenarios for users to step on.

[0064] The drive shaft 2 is rotatably mounted on a mounting bracket 1, which is used to connect to the vehicle body. As described above, the mounting bracket 1 can be mounted to the bottom of the vehicle body. The drive shaft 2 can be driven, for example, by a driver (such as a drive motor) mounted on the mounting bracket 1, to rotate in both forward and reverse directions.

[0065] The axis of drive shaft 2 is represented by X in the figure, and the axial direction of drive shaft 2 can be direction A in the figure. In the description of this utility model, direction A can be the left-right direction, and direction B is the front-back direction orthogonal to the left-right direction. When the retractable pedal device is installed near the side door of the vehicle, direction A is the front-back direction of the vehicle, direction B is the left-right direction of the vehicle, also referred to as the inward-outward direction, and the up-down direction is the up-down direction of the vehicle, i.e., the vertical direction. Of course, it can be understood that when the retractable pedal is installed near the tailgate of the vehicle, direction A can be the left-right direction of the vehicle, and direction B can be the front-back direction of the vehicle, also referred to as the inward-outward direction. In the following description of the embodiments, unless otherwise specified, the orientation and direction of the retractable pedal when it is installed near the side door of the vehicle are described.

[0066] The pedal 3 is movable between an extended position and a retracted position. The pedal 3 has a footrest 311 for passengers to step on when getting in and out of the vehicle. In the extended position, the footrest 311 generally faces upwards. It is understood that during the movement of the pedal 3 between the extended and retracted positions, the orientation of the footrest 311 can remain constant upwards, or it can change. Therefore, depending on the orientation of the vehicle's underside, the pedal 3 can be at different angles in the retracted position. For example, when the vehicle's underside is horizontal, the pedal 3 is horizontal, i.e., the footrest 311 faces upwards; when the vehicle's underside is tilted, the pedal 3 is also tilted in the retracted position. This allows the pedal to better conform to the vehicle in the retracted position, improving the vehicle's passability.

[0067] The pedal 3 has a first side and a second side axially on the drive shaft 2. Figures 1-3 In the middle, the first side of pedal 3 is the left side, and the second side of pedal 3 is the right side.

[0068] The first support arm assembly 4 is connected to the first side of the pedal 3. Specifically, the first support arm assembly 4 includes a first drive arm 41 and a first driven arm 42. The first end of the first drive arm 41 ( Figure 2 The upper end of the first drive arm 41 is fixed to the drive shaft 2 so that when the drive shaft 2 rotates, it drives the first drive arm 41 to swing. The second end of the first drive arm 41 ( Figure 2 The lower end of the first driven boom 42 is pivotally connected to the first side of the pedal 3. Figure 2 The upper end of the first driven boom 42 is pivotally connected to the mounting support 1, and the second end of the first driven boom 42 is... Figure 2 The lower end of the pedal 3 is pivotally connected to the first side of the pedal 3.

[0069] The second support arm assembly 5 is connected to the second side of the pedal 3. Specifically, the second support arm assembly 5 includes a second drive arm 51 and a second driven arm 52, the first end of the second drive arm 51 ( Figure 2 The upper end of the second drive arm 51 is fixed to the drive shaft 2 so that when the drive shaft 2 rotates, it drives the second drive arm 51 to swing. Figure 2 The lower end of the second driven boom 52 is pivotally connected to the second side of the pedal 3. Figure 2 The upper end of the second driven boom 52 is pivotally connected to the mounting support 1. Figure 2 The lower end of the pedal 3 is pivotally connected to the second side of the pedal 3.

[0070] like Figure 1As shown, the pivot center between the first driving arm 41 and the first side of the pedal 3 is located at the rear side of the pivot center between the first driven arm 42 and the first side of the pedal 3. The pivot center between the second driving arm 51 and the second side of the pedal 3 is located at the rear side of the pivot center between the second driven arm 52 and the second side of the pedal 3. By adjusting the position relationship of the pivot centers of the first side and the second side of the pedal and the pivot center on the mounting support, the operation trajectory of the pedal can be adjusted.

[0071] When the driving shaft rotates forward and reversely, a linkage mechanism is formed between the first support arm assembly, the second support arm assembly, the pedal and the mounting support, the first driving arm and the second driving arm are driven to swing by the driving shaft, and then the first driven arm and the second driven arm are driven to swing synchronously, so as to drive the pedal to move between the extended position and the retracted position. The telescopic pedal device of the embodiment has a compact overall structure, occupies a small space, and can improve the passability of the vehicle, and is especially suitable for vehicles with a low chassis.

[0072] The telescopic pedal device of some specific embodiments of the utility model is described below.

[0073] As Figures 1 to 4 shown, the telescopic pedal device 100 comprises a mounting support 1, a driving shaft 2, a pedal 3, a first support arm assembly 4 and a second support arm assembly 5.

[0074] The mounting support 1 comprises a mounting plate 11, a first mounting lug 12 and a second mounting lug 13. The mounting plate 11 can be a rectangular flat plate, so that the mounting plate 11 has no excessive protruding structure or special-shaped structure, thereby improving the compactness of the telescopic pedal device. The mounting plate 11 is provided with a plurality of mounting holes 111, and the mounting plate 11 can be mounted to the vehicle body through fasteners such as bolts passing through the mounting holes 11. The mounting plate 11 has a first end (left end in Figure 1 and Figure 2 ) and a second end (right end in Figure 1 and Figure 2 ) in the axial direction of the driving shaft 2. The first mounting lug 12 is arranged at the first end of the mounting plate 11, and the second mounting lug 13 is arranged at the second end of the mounting plate 11. The first mounting lug 12 extends downward from the first end of the mounting plate 11, and the second mounting lug 13 extends downward from the second end of the mounting plate 11.

[0075] The first mounting lug 12 is provided with a first shaft hole 121 and a first pivot hole 122 located in front of the first shaft hole 121, and the second mounting lug 13 is provided with a second shaft hole 131 and a second pivot hole 132 located in front of the second shaft hole 131. Wherein, the "front side" can refer to the front, the front upper side or the front lower side.

[0076] The driving shaft 2 is located below the mounting plate 11 and adjacent to the lower surface of the mounting plate 11, so that the structure of the mounting support 1 and the driving shaft 2 is more compact, occupies less space, further reduces the size of the entire telescopic pedal device in the up-down direction, and further improves the compactness.

[0077] The driving shaft 2 is rotatably supported in the first shaft hole 121 of the first mounting lug 12 and the second shaft hole 131 of the second mounting lug 13. The end of the first shaft hole 121 close to the second mounting lug 13 and the end of the second shaft hole 131 close to the first mounting lug 12 are both provided with a bushing 6. One end of the bushing 6 is provided with a flange 61. By providing the bushing 6, the first mounting lug 12 and the second mounting lug 13 can be prevented from being worn, and the maintenance cost in the later period can be reduced. The flange 61 can prevent sand from entering the shaft hole, and reduce the wear caused by sand. The bushing 6 can be made of a material with low friction coefficient and good wear resistance, so as to reduce the wear of the driving shaft, the first shaft hole and the second shaft hole, improve the rotation performance, and prolong the service life of the components.

[0078] The driving shaft 2 can be connected with a driving motor 7 mounted on the mounting support 1. The driving motor 7 can be mounted on the first mounting lug 12 or the second mounting lug 13. Preferably, the driving motor 7 is one, and one driving motor drives the driving shaft to rotate, and then drives the first support arm group and the second support arm group to swing, so as to reduce the number of driving motors, avoid the interference caused by the asynchronization of two driving motors, or the problem of complex structure and control caused by ensuring the synchronization of two driving motors.

[0079] As shown in Figure 1 and Figure 2 , a protruding column 133 is arranged on the side of the second mounting lug 13 away from the first mounting lug 12, and the protruding column 133 is provided with a threaded hole. The driving motor can be fixed on the protruding column 133 by means of bolts or other fasteners. The driving motor 7 is arranged on the side of the second mounting lug 13 away from the first mounting lug 12, which can also prevent sand from entering the second shaft hole 131 from the end of the second shaft hole 131 away from the first mounting lug 12.

[0080] The pedal 3 has a first side (left side in Figure 1 and Figure 2 ) and a second side (right side in Figure 1 and Figure 2 ) in the axial direction of the driving shaft 2. Specifically, the pedal 3 comprises a stepping plate part 31, a first extension beam 32 and a second extension beam 33. The upper surface of the stepping plate part 31 is a stepping surface 311.
