[0064] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0065] The pedal support for installing a pedal, the pedal mounting assembly, the telescopic pedal device and the vehicle equipment of the embodiments of the present application are described below with reference to the drawings.

[0066] The vehicle device of the embodiment of the present application comprises a vehicle 2000 and a telescopic step device 1000, the telescopic step device 1000 is installed on the vehicle 2000 and is movable between an extended position and a retracted position, and is used for assisting a person to get on or off the vehicle.

[0067] The telescopic step device 1000 can be installed on at least one of the left side and the right side of the vehicle 2000, or can be installed on the rear side of the vehicle 2000. In the following embodiment description, the telescopic step device 1000 is installed on the left side of the vehicle 2000.

[0068] As shown in Figure 13 and Figure 14 , in some embodiments, the vehicle device further comprises a side guard 500 installed on the vehicle 2000, for example, installed on the lower edge of the left side and the right side of the vehicle 2000, used for protecting the side of the vehicle, and optionally, the side guard 500 can be used as a fixed step. The telescopic step device 1000 is installed on the bottom 20001 of the vehicle body of the vehicle 2000, wherein when in the retracted position, the step 200 is located below and inside the side guard 500, and when in the extended position, the step 200 is located below the side guard 500 and at least partially outside the side guard 500. Therefore, not only can the side guard 500 serve as protection for the vehicle and the telescopic step device, but optionally, it can also be used as a fixed step, and the side guard and the telescopic step device form a two-stage step, which is particularly suitable for vehicles with a high chassis.

[0069] As shown in Figures 1 to 3 , the telescopic step device 1000 of the embodiment of the present application comprises a step mounting assembly 100 and a step 200, the step 200 is installed on the step mounting assembly 100 to move between an extended position and a retracted position. The step mounting assembly 100 has a step support 2 connected with the step 200, as shown in Figure 4 , the transverse direction of the step support 2 is parallel to the length direction of the step 200, for example, the transverse direction of the step support 2 is the left-right direction in Figure 4 .

[0070] When the telescopic step device 1000 is installed on the left side or the right side of the vehicle 2000, the transverse direction of the step support 2 is consistent with the front-rear direction of the vehicle 2000, and the left-right direction of the step 200 is consistent with the front-rear direction of the vehicle 2000. The outer side (outer end) of the step support 2 refers to the side of the step support 2 away from the vehicle 2000 along the left-right direction of the vehicle, and the inner side (inner end) of the step support 2 refers to the side of the step support 2 adjacent to the vehicle 2000 along the left-right direction of the vehicle.

[0071] When the extendable pedal arrangement 1000 is mounted to the rear side of the vehicle, the lateral direction of the pedal support 2 coincides with the left-right direction of the vehicle 2000, and the length direction of the pedal 200 coincides with the left-right direction of the vehicle 2000. The outer side (outer end) of the pedal support 2 refers to the side of the pedal support 2 facing away from the vehicle 2000, and the inner side (inner end) of the pedal support 2 refers to the side of the pedal support 2 adjacent to the vehicle 2000.

[0072] In the extended position, the pedal 200 and the pedal support 2 extend outward of the vehicle body outer edge 20002 so that a user can step on the pedal 200. In the retracted position, the pedal 200 and the pedal support 2 are retracted inside the vehicle body outer edge 20002.

[0073] As shown in Figures 1 to 7 , the pedal mounting assembly 100 of the embodiments of the present application comprises a first support arm 3, a second support arm 4, and a pedal support 2. The pedal support 2 has a first side 201 and a second side 202 facing away from each other in the lateral direction thereof. As shown in Figure 4 , the first side 201 is the right side of the pedal support 2, and the second side 202 is the left side of the pedal support 2.

[0074] At least one of the first side 201 and the second side 202 is connectable with the pedal 200, the first support arm 3 is pivotably connected with the pedal support 2, and the second support arm 4 is pivotably connected with the pedal support 2 to move the pedal support 2 and the pedal 200 between the extended position and the retracted position.

[0075] The first support arm 3 and the second support arm 4 are respectively pivotably connected with the vehicle body bottom 20001 of the vehicle 2000.

[0076] For example, the first support arm 3 and the second support arm 4 can be directly pivotably connected with the vehicle body bottom 20001 of the vehicle 2000. In some embodiments, the first support arm 3 and the second support arm 4 are indirectly pivotably connected with the vehicle body bottom 20001 of the vehicle 2000.

[0077] In the example of the present application, the first support arm 3, the second support arm 4, and the pedal support 2 constitute a linkage mechanism, which can be connected with a driving device 400 to drive the pedal support 2 and the pedal 200 to move between the extended position and the retracted position. In other words, the driving device 400 can be connected with the first support arm 3 or the second support arm 4, and in the illustrated embodiment, the driving device 400 is connected with the first support arm 3.

[0078] According to the pedal mounting assembly 100 in the embodiment of the utility model, at least one of the first side 201 and the second side 202 of the pedal support 2 is connectable with the pedal 200, so that the overall thickness of the pedal support 2 and the pedal 200 in the up-down direction after assembly is small in the extended position, especially in the retracted position, the required installation space of the pedal mounting assembly 100 is small, and the pedal mounting assembly 100 is particularly suitable for application to a vehicle 2000 with a low chassis. Therefore, the pedal mounting assembly 100 in the embodiment of the utility model has the advantages of small required space, strong applicability and improved passability of the vehicle.

[0079] In the related art, the pedal 200 is usually mounted on the pedal support 2 along the thickness direction (i.e., the up-down direction of the vehicle 2000), that is, the pedal support and the pedal are stacked in the up-down direction, so that the pedal 200 and the pedal support 2 occupy a large space. For a vehicle with a low chassis, the pedal 200 and the pedal support 2 are prone to knocking against ground obstacles, and have a short service life.

[0080] The pedal mounting assembly 100 in the embodiment of the utility model is connected with at least one of the first side 201 of the pedal support 2 and the second side 202 of the pedal support 2, so that the pedal support 2 and the pedal 200 are located at substantially the same horizontal height. That is, the pedal support 2 and the pedal 200 are arranged side by side in the length direction of the pedal 200, so that the overall thickness of the pedal support 2 and the pedal 200 after assembly can be reduced, and the upper surface of the pedal support 2 can be used for pedaling, so that the pedal mounting assembly 100 has a compact structure, is beneficial to improving the space utilization rate, and has good use effect.

[0081] Compared with the related art in which the support arm is directly connected with the pedal, in the embodiment of the utility model, the pedal mounting assembly 100 is pivotally connected with the pedal support 2 through the first support arm 3 and the second support arm 4, and the pedal 200 is connected with the pedal support 2, which can improve the carrying capacity of the pedal mounting assembly 100 and the pedal 200 after assembly, so that the user can pedal the pedal 200 more stably and the pedal 200 is not prone to damage. On the other hand, the pedal support 2 serves as an adapter and can be pre-assembled with the first support arm 3 and the second support arm 4 into an integral unit before leaving the factory, so that the pedal mounting assembly 100 and the pedal 200 can be packaged and transported separately, thereby reducing the transportation cost and facilitating the subsequent assembly and operation.

[0082] As Figure 8 and Figure 9As shown, the pedal support 2 of the embodiment of the utility model comprises a first side wall 22, a second side wall 23 and a connecting portion 24. The first side wall 22 and the second side wall 23 are flat and arranged in parallel with each other. The connecting portion 24 is connected between the outer end of the first side wall 22 and the outer end of the second side wall 23 so as to enclose the pedal support groove 21 which is open inward. The pedal support 2 has a first side 201 and a second side 202 which are away from each other in the width direction of the pedal support groove 21, and at least one of the first side 201 and the second side 202 is provided with a support matching portion 25 which is connectable with the pedal 200.

[0083] It should be noted that the inner end of the pedal support groove 21 refers to the end of the pedal support groove 21 which is adjacent to the vehicle 2000. The outer end of the pedal support groove 21 refers to the end of the pedal support groove 21 which is away from the vehicle 2000.

[0084] The pedal support 2 for mounting the pedal according to the embodiment of the utility model is provided with the support matching portion 25 which is connectable with the pedal 200 at least on one of the first side 201 and the second side 202 of the pedal support 2, and the pedal 200 is connected to the pedal support 2 in parallel in the length direction of the pedal 200, so that the overall thickness of the pedal support 2 and the pedal 200 in the up-down direction after assembly can be reduced, and the space required for installation is further reduced, and the pedal support 2 is particularly suitable for application on a vehicle with a low chassis. Therefore, the pedal support 2 for mounting the pedal according to the embodiment of the utility model occupies a small space and has strong applicability, and the passability of the vehicle is improved.

[0085] Since the pedal support 2 is generally in the shape of a U, the opening of the pedal support groove 21 is towards the inner side of the pedal support 2. Thus, the first support arm and the second support arm of the pedal mounting assembly 100 can be provided with a space for avoiding, and the pedal support 2 and the pedal 200 can be closer to the bottom of the vehicle body in the retracted position, so that the probability of knocking against an obstacle can be reduced, and the passability of the vehicle is improved.

[0086] Optionally, as shown in Figure 8 and Figure 9 , the outer surface (which can also be referred to as the outer surface of the pedal support) 203 of the connecting portion 24 is inclined inwardly in the direction from top to bottom, that is, the cross section of the connecting portion 24 is generally triangular, so that the possibility of knocking against an obstacle on the outer side of the connecting portion 24 can be reduced. As shown in Figure 9 and Figure 15 , the inner surface 204 of the pedal support 2 is generally a vertical surface, so that the processing and manufacturing of the pedal support 2 can be facilitated.

[0087] As shown in Figure 8 and Figure 9As shown, the inner surface 28 of the connecting portion 24 is inclined inwardly along the downward direction, and the inner surface 28 of the connecting portion 24 is the surface of the connecting portion 24 defining the pedal support groove 21. Since the inner surface 28 of the connecting portion 24 is inclined, the first support arm and the second support arm of the pedal mounting assembly 100 can be provided with a clearance, and in the retracted position, the pedal support 2 and the pedal 200 can be closer to the bottom of the vehicle body, reducing the probability of the pedal support 2 and the pedal 200 colliding with protruding obstacles on the ground, and improving the passability of the vehicle. On the other hand, the inclined inner surface 28 can reduce the impact on the structural strength of the pedal support 2.

[0088] In some embodiments, as shown in Figure 8 and Figure 9 , the first side wall surface 211 of the pedal support groove 21 is provided with a first boss 26, and the second side wall surface 212 of the pedal support groove 21 is provided with a second boss 27. The first boss 26 and the second boss 27 are opposite to each other along the transverse direction of the pedal support 2 (i.e., the length direction of the pedal 200), and the outer end of the first boss 26 and the outer end of the second boss 27 are connected to the connecting portion 24. The first boss 26 can be integrally formed with the first side wall 22 and the connecting portion 24, and the second boss 27 can be integrally formed with the second side wall 23 and the connecting portion 24, in other words, the pedal support 2 is integrated, thereby improving the overall structural strength and load capacity of the pedal support 2. Compared with the related art in which the pedal support 2 is thickened in the upward and downward direction and the length is increased, the pedal support 2 of the embodiment of the utility model is thinner, and is farther from the ground in the retracted position.

[0089] In some embodiments, as shown in Figures 19 to 21 , only one side (the first side 201 or the second side 202) of the pedal support 2 is used to connect with the pedal 200. Specifically, there are two pedal mounting assemblies 100, and the pedal 200 is arranged between the two pedal mounting assemblies 100. At this time, one end of the pedal 200 along the length direction is connected to the first side 201 of the pedal support 2 of one pedal mounting assembly 100. The other end of the pedal 200 along the length direction is connected to the second side 202 of the pedal support 2 of the other pedal mounting assembly 100.

[0090] In other embodiments, as shown in Figure 7 , Figure 17 and Figure 18As shown, the first side 201 and the second side 202 of the pedal support 2 are respectively connected with different pedals 200. Specifically, there are three pedal mounting assemblies 100 and two pedals 200, and the three pedal mounting assemblies 100 and the two pedals 200 are arranged alternately along the length direction of the pedals 200. The first side 201 and the second side 202 of the pedal support 2 of the pedal mounting assembly 100 located in the middle position are respectively connected with two pedals 200, so that the telescopic pedal device 1000 can be adapted to vehicles 2000 with different wheelbase, and the application range is wider.

[0091] Optionally, at least one of the first side 201 and the second side 202 is provided with a support matching part 25 connectable with the pedal 200. It can be understood that the support matching part 25 can be used to connect the pedal matching part 2003 of the pedal 200, and the pedal matching part 2003 and the support matching part 25 are engaged with each other to fix the pedal support 2 and the pedal 200. Exemplarily, the engagement mode of the pedal matching part 2003 and the support matching part 25 can be plug-in.

[0092] For example, as shown in Figure 21 and Figure 22 , the support matching part 25 is arranged on one side of the pedal support 2 along the transverse direction thereof. For example, as shown in Figure 8 and Figure 9 , the support matching parts 25 are arranged on both sides of the pedal support 2 along the transverse direction thereof, i.e., the first side 201 and the second side 202 are respectively provided with the support matching part 25. Through the support matching part 25, the pedal support 2 and the pedal 200 are connected, and the structure is more stable.

[0093] Specifically, as shown in Figure 8 , the support matching part 25 can include a plurality of prisms, and the plurality of prisms are arranged at intervals in the longitudinal direction of the pedal support 2. It can be understood that the longitudinal direction of the pedal support 2 is consistent with the width direction of the pedal 200, i.e., the inner-outer direction in Figure 4 . The plurality of prisms are respectively plugged into a plurality of pedal matching parts 2003 of the pedal 200, so that the structural stability can be further improved.

[0094] In the illustrated embodiment, the pedal matching part 2003 of the pedal 200 is a matching hole arranged on the end face of the pedal 200 along the length direction thereof. The number of the matching holes is the same as the number of the prisms and the matching holes are plugged together one by one.

[0095] For example, the pedal 200 can be a hollow aluminum alloy profile or a profile of other material. The pedal matching part 2003 can be directly formed in the pedal 200 during production and processing of the pedal 200. The cross-sectional profile of the prism matches the pedal matching part 2003 (the matching hole).

[0096] Exemplarily, the cross section of the at least one prism is non-circular. For example, the prism can be a rectangular prism or a triangular prism. In this way, the relative rotation between the pedal support 2 and the pedal 200 can be avoided. For example, there can be three prisms, which are arranged along the longitudinal direction (i.e. the inner-outer direction) of the pedal support 2.

[0097] Specifically, as shown in Figure 8 the plurality of prisms include a first prism 251, a second prism 252 and a third prism 253 arranged along the inner-outer direction, the third prism 253 being located between the first prism 251 and the second prism 252, and the second prism 252 corresponding to the connecting portion 24 in the width direction of the pedal support groove 21. It can be understood that the second prism 252 is located outside the first prism 251 and is connected to the connecting portion 24, so that the structural strength of the pedal support 2 as a whole can be improved.

[0098] In the example of the utility model, the cross section of the first prism 251 and the third prism 253 is rectangular, and the cross section of the second prism 252 is triangular, so that the structural strength is further improved.

[0099] In an example, as shown in Figure 4 the pedal mounting assembly 100 further includes an end cover 300, the end cover 300 is provided with an end cover matching portion 3001, the first side 201 and the second side 202 are each provided with a support matching portion 25, and the end cover matching portion 3001 is engaged with the support matching portion 25 of one side of the first side 201 and the second side 202 to connect the end cover 300 to the pedal support 2. It can be understood that the support matching portion 25 of one side of the first side 201 and the second side 202 is adapted to be connected to the pedal 200, and the support matching portion 25 of the other side of the first side 201 and the second side 202 is adapted to be connected to the end cover 300.

[0100] By providing the end cover, the first side 201 and the second side 202 of the pedal support 2 are each provided with a support matching portion 25, and the support matching portion 25 of the side of the pedal support connected to the pedal can be connected to the end cover, so that the versatility of the pedal mounting assembly 100 is improved, the number of production molds is reduced, and the manufacturing cost is low.

[0101] In other words, when the support matching portion 25 of the first side 201 of the pedal support 2 is connected, the end cover 300 can be provided on the support matching portion 25 of the second side 202 of the pedal support 2. Similarly, when the support matching portion 25 of the second side 202 of the pedal support 2 is connected, the end cover 300 can be provided on the support matching portion 25 of the first side 201 of the pedal support 2. In this way, the pedal supports 2 of the pedal mounting assemblies 100 at different positions are universal to each other, and a set of molds can be shared, so as to reduce the production and assembly costs.

[0102] As shown in Figure 4As shown, the outer periphery contour of the end face of the end cover 300 (i.e. the surface of the end cover 300 facing the pedal support 2) is substantially flush with the outer periphery contour of the side surface of the pedal support 2, so that there is no step structure between the assembled end cover 300 and the pedal support 2. On the one hand, the appearance of the pedal mounting assembly 100 is more beautiful and the integrity is better. On the other hand, part of the end cover 300 can also be used by the user to step on, thereby improving the space utilization of the pedal mounting assembly 100 and the compactness of the structural design.

[0103] Further, the outer periphery contour of the cross section of the pedal 200 is substantially aligned with the outer periphery contour of the side surface of the pedal support 2, so that the pedal 200 and the pedal support 2 after being connected have better integrity.

[0104] In another example, as shown in Figures 19 to 21 , the pedal mounting assembly 100 includes an end cover 300, one of the first side 201 and the second side 202 is provided with a support matching part 25, and the end cover 300 is connected to the other one of the first side 201 and the second side 202 or is integrally formed with the pedal support 2. It can be understood that the support matching part 25 is only arranged on one side of the pedal support 2 in the transverse direction, which is used to be connected with the pedal 200. The other side of the pedal support 2 in the transverse direction is provided with the end cover 300. The end cover 300 and the pedal support 2 can be connected in a detachable manner, or can be integrally formed with the pedal support 2.

[0105] In some embodiments, as shown in Figures 6 to 9 , the pedal support 2 is a substantially U-shaped pedal support with a pedal support groove 21, and the pedal support 2 includes a first pedal support side wall 22, a second pedal support side wall 23 and a connecting part 24, and the pedal support groove 21 is open inward. In other words, the pedal support 2 is a U-shaped plate with a pedal support groove 21 open inward, and the pedal support 2 has a flat structure, further reducing the occupied space.

[0106] The first support arm 3 has a first end (upper end in Figure 13 ) 301 and a second end (lower end in Figure 13 ) 302 along the length direction thereof, and the second support arm 4 has a first end (upper end in Figure 13 ) 41 and a second end (lower end in Figure 13 ) 42 along the length direction thereof, and the second end 302 of the first support arm 3 and the second end 42 of the second support arm are respectively pivotally connected with the pedal support 2 in the pedal support groove 21, and the pedal support groove 21 can provide a space for the rotation of the first support arm 3 and the second support arm 4.

[0107] Compared with the pivot point of the support arm and the pedal support is arranged on the upper side, the lower side or the front side of the pedal support 2, in the embodiment of the utility model, the pedal mounting assembly 100 can reduce the occupied space in the extended position and the retracted position, and the compact structure is improved.

[0108] As shown in Figure 13 , the third pivot axis X3 of the second end 302 of the first support arm is located inside the fourth pivot axis X4 of the second end 42 of the second support arm, that is, the first support arm 3 is closer to the inside than the second support arm 4.

[0109] In some embodiments, as shown in Figures 5 to 8 , the third pivot axis X3 of the second end 302 of the first support arm 3 is located inside the first boss 26 and the second boss 27 and passes through the first side wall 22 of the pedal support and the first side wall 23 of the pedal support. That is, the third pivot axis X3 does not pass through the first boss 26 and the second boss 27.

[0110] As shown in Figures 5 to 8 , the fourth pivot axis X4 of the second end 42 of the second support arm 2 passes through the first side wall 22 of the pedal support, the first boss 26, the second boss 27 and the second side wall 23 of the pedal support. It can be understood that the third pivot axis X3 and the fourth pivot axis X4 are located in the same horizontal plane, and the second end 42 of the second support arm is arranged between the first boss 26 and the second boss 27.

[0111] Optionally, as shown in Figure 8 , the pedal support 2 has a third hole 205 and a fourth hole 206, and the third hole 205 passes through the first side wall 22 of the pedal support and the second side wall 23 of the pedal support. Specifically, as shown in Figure 4 and Figure 5 , the third hole 205 is used for penetrating the third shaft 8, and the central axis of the third shaft 8 is the same as the third pivot axis X3, and the second end 302 of the first support arm 3 is connected with the third shaft 8. The second end 302 of the first support arm 3 is provided with a sixth hole 3020, and the third shaft 8 penetrates the sixth hole 3020 and the third hole 205 on the pedal support 2, so that the second end 302 of the first support arm is rotatable relative to the pedal support 2.

[0112] As shown in Figure 8 , the fourth hole 206 passes through the first side wall 22, the first boss 26, the second boss 27 and the second side wall 23, and the third hole 205 is located inside the fourth hole 206. As shown in Figure 4 and Figure 5As shown, the fourth hole 206 is used to pass through the fourth shaft 9. The central axis of the fourth shaft 9 is the same axis as the fourth pivot axis X4. The second end 42 of the second support arm is provided with an eighth hole 421. The fourth shaft 9 passes through the eighth hole 421 on the second support arm 4 and the fourth hole 206 on the pedal support 2 so that the second end 42 of the second support arm can rotate relative to the pedal support 2.

[0113] like Figures 6 to 8 As shown, the inner surface 28 of the connecting part 24 is inclined to avoid the second support arm 4 in the retracted position, so that the dimensions of the pedal support 2 and the second support arm 4 in the vertical direction are smaller in the retracted position.

[0114] In some embodiments, such as Figure 13 As shown, in the extended position, the length of the first support arm 3 within the pedal support groove 21 is L3a, as... Figure 14 As shown, in the retracted position, the length of the first support arm 3 within the pedal support groove 21 is L3b, where L3a is less than L3b. In other words, the dimension of the first support arm 3 in the retracted position within the pedal support groove 21 is greater than the dimension of the first support arm 3 in the extended position within the pedal support groove 21.

[0115] In the extended position, such as Figure 13 As shown, the length of the second support arm 4 located in the pedal support groove 21 is L4a, as... Figure 14 As shown, in the retracted position, the length of the second support arm 4 within the pedal support groove 21 is L4b, where L4a is less than L4b. In other words, the dimension of the second support arm 4 in the retracted position within the pedal support groove 21 is greater than the dimension of the second support arm 4 in the extended position within the pedal support groove 21.

[0116] Therefore, in the retracted position, the first support arm 3 and the second support arm 4 can make fuller use of the space of the pedal support groove 21, and the pedal support 2 and the pedal can be placed higher, that is, closer to the bottom of the vehicle body, thus improving the vehicle's passability.

[0117] In some embodiments, such as Figures 10 to 13 As shown, the first end 301 of the first support arm 3 is provided with a receiving groove 3011, and the first end 41 of the second support arm 4 is received in the receiving groove 3011. Since the first end 41 of the second support arm 4 is received in the receiving groove 3011, the first pivot axis X1 of the first end 301 and the second pivot axis X2 of the second end 42 can be closer, thereby making the first support arm 3 and the second support arm 4 more compact.

[0118] like Figure 5 , Figure 10 and Figure 11As shown, the first end 41 of the second support arm 4 is provided with a cylindrical portion 411, which is accommodated in the accommodating groove 3011. It can be understood that the cylindrical portion 411 can be rotatably accommodated in the accommodating groove 3011, and when the first end 41 of the second support arm rotates, the cylindrical portion 411 can rotate synchronously in the accommodating groove 3011, thereby the movement track of the first support arm 3 and the second support arm 4 can be constrained, and the linkage mechanism composed of the first support arm 3, the second support arm 4 and the pedal support 2 moves more smoothly.

[0119] As shown in Figure 5 and Figure 10 , the cylindrical portion 411 is provided with a seventh hole 420 penetrating along the axial direction thereof, and the second shaft 7 is arranged in the seventh hole 420, and the second shaft 7 can be connected with the vehicle 2000 or the mounting support 1. Exemplarily, the pedal mounting assembly 100 comprises the mounting support 1, and the mounting support 1 is provided with a second hole 17, and the second shaft 7 is rotatably supported in the second hole 17, so that the second support arm 4 and the mounting support 1 are rotatably connected.

[0120] As shown in Figure 5 , Figure 13 and Figure 14 , the pedal mounting assembly 100 further comprises a baffle 5, which is mounted on the first end 301 of the first support arm 3 and is used to prevent the first end 41 of the second support arm from being pulled out of the accommodating groove 3011. The baffle 5 can rotate with the first support arm 3. The baffle 5 can limit the first end 41 of the second support arm from being pulled out of the accommodating groove 3011, and can also shield and hide the cooperation structure of the first end 41 of the second support arm and the first support arm 3, so as to not only ensure the appearance aesthetics of the pedal mounting assembly 100, but also reduce the probability of sand and other impurities entering the accommodating groove 3011, thereby helping to improve the reliability and stability of the cylindrical portion 411 when rotating in the accommodating groove 3011.

[0121] In an example, as shown in Figure 16 , in the retracted position, the baffle 5 is stopped outside the first support arm 3 and the second support arm 4, so as to not only ensure the appearance aesthetics and integrity of the pedal mounting assembly 100, but also reduce the probability of sand and other impurities entering the accommodating groove 3011, thereby helping to improve the reliability and stability of the cylindrical portion 411 when rotating in the accommodating groove 3011.

[0122] As shown in Figure 11 , the first support arm 3 is provided with a baffle mounting hole 36, and the baffle mounting hole 36 is used to pass through a rivet or a screw to mount the baffle 5.

[0123] In some embodiments, as shown in Figure 5 and Figure 7As shown, the first end 301 of the first support arm 3 is provided with a clamping block mounting hole 3012 extending along the thickness direction of the first support arm 3 and a fifth hole 3010 extending along the width direction of the first support arm 3, the fifth hole 3010 passing through the clamping block mounting hole 3012, a first shaft 6 for driving the first support arm 3 to rotate being fitted in the fifth hole 3010, and a clamping block 62 being fitted in the clamping block mounting hole 3012, the first shaft 6 having a clamping groove 61, a portion of the clamping block 62 being engaged in the clamping groove 61 to prevent the first shaft 6 from rotating in the fifth hole 3010.

[0124] The clamping block 62 is used to limit the rotation of the first shaft 6 relative to the fifth hole 3010. That is, the first shaft 6 rotates together with the first support arm 3.

[0125] As shown in Figure 5 , the first shaft 6 is used to be connected with a driving device 400, so that the driving device 400 drives the first support arm 3 to rotate through the first shaft 6. The driving device 400 can be a motor, or an integrated module of a motor and a speed reducer. The driving device 400 can drive the first shaft 6 to rotate, and the first shaft 6 drives the first support arm 3 to rotate synchronously around the axis of the first shaft 6 (i.e. the first pivot axis X1) under the constraint of the clamping block 62.

[0126] As shown in Figure 5 and Figure 7 , the clamping groove 61 is provided on the outer circumferential surface of the first shaft 6, and the clamping block 62 is fitted in the clamping block mounting hole 3012, a portion of the clamping block 62 being embedded in the clamping groove 61, thereby limiting the rotation of the first shaft 6 relative to the fifth hole 3010, i.e. limiting the rotation of the first shaft 6 relative to the first support arm 3.

[0127] Exemplarily, as shown in Figure 5 and Figure 7 , the clamping block 62 is connected with the first support arm 3 through a fastener 63 to prevent the clamping block 62 from being pulled out of the clamping block mounting hole 3012. For example, the fastener 63 can be a screw.

[0128] In some embodiments, as shown in Figure 13 and Figure 14 , the pedal mounting assembly 100 further comprises a first buffer block 35 and a second buffer block 43, the first buffer block 35 being arranged on the first end 301 of the first support arm, and the second buffer block 43 being arranged on the second support arm 4. In the extended position, the first buffer block 35 faces the second support arm 4. In the retracted position, the second buffer block 43 faces the first support arm 3.

[0129] As shown in Figure 13 and Figure 14As shown, in the extended position, the first buffer block 35 abuts against the second support arm 4. In the retracted position, the second buffer block 43 abuts against the first support arm 3. This prevents direct collision between the first support arm 3 and the second support arm 4 when the pedal mounting assembly 100 moves between the extended and retracted positions, reducing noise during operation and preventing scratches and damage to the first and second support arms 3 and 4.

[0130] The first buffer block 35 and the second buffer block 43 can be made of elastic or other soft materials, such as rubber.

[0131] like Figure 11 and Figure 12 As shown, the first support arm 3 has an arm groove 31 extending along its length direction, and the depth of the arm groove 31 can gradually change along its length direction. A portion of the second support arm 4 is accommodated within the arm groove 31. In a cross-section orthogonal to the length direction of the first support arm 3, the cross-sectional profile of the first support arm 3 is generally U-shaped.

[0132] like Figure 11 As shown, the arm groove 31 includes a first side wall 32, a second side wall 33, and a bottom surface 34. The first side wall 32 and the second side wall 33 are respectively arranged on both sides of the bottom surface 34 of the arm groove along the width direction of the first support arm 3 to form a generally U-shaped space.

[0133] Since a portion of the second support arm 4 is housed within the arm groove 31, the pedal mounting assembly 100 has a more compact structure in the retracted position. The first support arm 3 can constrain and protect the second support arm 4, which helps to improve the stability of the pedal mounting assembly's movement.

[0134] In some embodiments, such as Figures 13 to 16 As shown, the pedal mounting assembly 100 also includes a mounting bracket 1 for connection to the vehicle 2000. The first end 301 of the first support arm 3 is connected to the mounting bracket 1 and is pivotable about a first pivot axis X1; the second end 302 of the first support arm is connected to the pedal bracket 2 and is pivotable about a third pivot axis X3; the first end 41 of the second support arm is connected to the mounting bracket 1 and is pivotable about a second pivot axis X2; and the second end 42 of the second support arm is connected to the pedal bracket 2 and is pivotable about a fourth pivot axis X4.

[0135] like Figure 13 and Figure 14 As shown, the mounting bracket 1, the first support arm 3, the second support arm 4 and the pedal bracket 2 constitute a linkage mechanism. When the driving device 400 drives the first support arm 3 to rotate around the first pivot axis X1, the second support arm 4 rotates synchronously as a driven rod, thereby driving the pedal bracket 2 and the pedal connected thereto to extend or retract.

[0136] As shown in Figure 14 , the mounting bracket 1 can protrude out of the vehicle body outer edge 20002 in the horizontal direction, so that the side rod 500 can be mounted to the mounting bracket 1, improving the convenience of mounting the side rod 500. Alternatively, as shown in Figure 15 , the mounting bracket 1 can be located inside the vehicle body outer edge 20002 in the horizontal direction.

[0137] In some examples, as shown in Figure 13 and Figure 14 , the first pivot axis X1 is located inside the second pivot axis X2, and the third pivot axis X3 is located inside the fourth pivot axis X4.

[0138] As shown in Figure 5 , the first shaft 6 passes through the first hole 16 on the mounting bracket 1, and the first shaft 6 is connected to the first end 301 of the first support arm. The first pivot axis X1 is collinear with the central axis of the first shaft 6.

[0139] As shown in Figure 5 , the mounting bracket 1 has a mounting bracket slot 11 extending in the length direction thereof, and the first end 301 of the first support arm is pivotably connected to the mounting bracket 1 within the mounting bracket slot 11, and the first end 41 of the second support arm is pivotably connected to the mounting bracket 1 within the mounting bracket slot 11.

[0140] In the extended position, the length of the first support arm 3 within the mounting bracket slot 11 is L1a, and in the retracted position, the length of the first support arm 3 within the mounting bracket slot 11 is L1b, where L1a is less than L1b.

[0141] As shown in Figures 13 to 16 , in the extended position, the length of the second support arm 4 within the mounting bracket slot 11 is L2a, and in the retracted position, the length of the second support arm 4 within the mounting bracket slot 11 is L2b, where L2a is less than L2b.

[0142] Thus, in the retracted position, the first support arm 3 and the second support arm 4 can make full use of the space of the mounting bracket slot 11, and the pedal bracket 2 and the pedal 200 can be closer to the bottom of the vehicle body, i.e., the pedal bracket 2 and the pedal 200 can be higher.

[0143] Alternatively, as shown in Figure 16 , in the retracted position, the upper surface 29 of the pedal bracket is adjacent to the bottom surface 101 of the mounting bracket. Thus, the size of the pedal mounting assembly 100 in the retracted position can be further reduced, and the pedal bracket 2 and the pedal 200 are closer to the bottom of the vehicle body, which is beneficial to expand the application range of the pedal mounting assembly 100.

[0144] Exemplarily, as shown in Figure 16 , the first pivot axis X1 is located inside the second pivot axis X2, and the third pivot axis X3 is located inside the fourth pivot axis X4.As shown, the distance G between the upper surface 29 of the pedal support and the bottom surface 101 of the mounting support is less than 20 mm. Preferably, the distance G between the upper surface 29 of the pedal support and the bottom surface 101 of the mounting support is greater than 1 mm and less than 8 mm. For example, G can be 1 mm, 2 mm, 4 mm, 6 mm, or 8 mm.

[0145] like Figure 5 As shown, the mounting bracket 1 includes an extension 15 that extends horizontally inward. The extension 15 can be connected to the bottom of the vehicle body 20001 to improve the reliability of the connection between the pedal mounting assembly 100 and the vehicle 2000.

[0146] like Figure 5 As shown, the mounting bracket 1 includes a first sidewall 12, a second sidewall 13, and a top wall 14. The first sidewall 12 and the second sidewall 13 are arranged at intervals along the transverse direction (length direction of the pedal 200) of the mounting bracket 1. The top wall 14 is connected to the first sidewall 12 and the second sidewall 13 to enclose the mounting bracket groove 11.

[0147] In some embodiments, such as Figures 13 to 16 As shown, in the retracted position, in a plane orthogonal to the first pivot axis X1, i.e., along the length of the pedal 200, the outer edge 240 of the pedal support 2 is located inside the second pivot axis X2. That is, when the pedal support 2 is in the retracted position, the outer edge 240 is further inward and closer to the vehicle 2000 than the position of the second pivot axis X2, and the pedal support 2 and the pedal 200 are closer to the bottom of the vehicle body in the retracted position, reducing the possibility of scraping against obstacles.

[0148] For example, such as Figure 14 As shown, in a plane orthogonal to the first pivot axis X1, the outer edge 240 of the pedal support is located inside the first pivot axis X1. Therefore, in the retracted position, the pedal support 2 and the pedal 200 are further inward and upward, reducing the probability of rubbing against obstacles.

[0149] Optionally, such as Figure 14 As shown, in a plane orthogonal to the first pivot axis X1, the outer edge 240 of the pedal support 2 is aligned with the first pivot axis X1 in the vertical direction. Further optionally, in a plane orthogonal to the first pivot axis X1, the outer edge 240 of the pedal support is located outside and adjacent to the first pivot axis X1. Preferably, the distance between the outer edge 240 of the pedal support and the first pivot axis X1 is less than 5 mm.

[0150] like Figure 14As shown, in a plane orthogonal to the first pivot axis X1, in the retracted position, the angle θ between the first line S1 connecting the first pivot axis X1 and the third pivot axis X3 and the horizontal direction is greater than or equal to 25 degrees and less than or equal to 35 degrees. Through experimental research, the inventors discovered that when the angle θ between the first line S1 and the horizontal plane is within the above range, it can reduce the vertical height of the pedal mounting assembly 100 after retraction and avoid interference between the first support arm 3 and the vehicle 2000, thereby improving the space utilization of the pedal mounting assembly 100 on the vehicle 2000 and making the structure of the pedal mounting assembly 100 more compact.

[0151] For example, the angle θ between the first line S1 and the horizontal plane can be 25 degrees, 28 degrees, 30 degrees, 32 degrees, or 35 degrees.

[0152] Similarly, Figure 14 As shown, in a plane orthogonal to the first pivot axis X1, in the retracted position, the angle θ between the second line S2 connecting the second pivot axis X2 and the fourth pivot axis X4 and the horizontal direction is greater than or equal to 25 degrees and less than or equal to 35 degrees. It can be understood that the angle θ between the second line S2 and the horizontal plane is selected between 25 degrees and 35 degrees. The inventors of this application, through experimental research and verification, discovered that when the angle θ between the second line S2 and the horizontal plane is selected within the above range, it can reduce the height dimension of the pedal mounting assembly 100 after retraction and avoid interference between the retracted second support arm 4 and the vehicle 2000, thereby improving the space utilization rate of the pedal mounting assembly 100 on the vehicle 2000 and making the structure of the pedal mounting assembly 100 more compact.

[0153] It should be noted that the angle between the first line S1 and the horizontal plane and the angle between the second line S2 and the horizontal plane can be equal or unequal. For example, the angle between the second line S2 and the horizontal plane can be 25 degrees, 28 degrees, 30 degrees, 32 degrees, or 35 degrees.

[0154] Preferably, in the retracted position, the second line S2 connecting the second pivot axis X2 and the fourth pivot axis X4 is generally parallel to the first line S1.

[0155] like Figure 14 and Figure 15 As shown, when the pedal mounting assembly 100 is in the retracted position, the first support arm 3 extends downwards and inclines generally toward the inside of the vehicle 2000 in the direction from the first end 301 to the second end 302 of the first support arm. The second support arm 4 extends downwards and inclines generally toward the inside of the vehicle 2000 in the direction from the first end 41 to the second end 42 of the second support arm. In the retracted position, the first support arm 3 is located above the second support arm 4.

[0156] As shown in Figure 13 and Figure 15 , when the pedal mounting assembly 100 is in the extended position, the first support arm 3 extends downwardly generally toward the outside of the vehicle 2000 in the direction from the first end 301 of the first support arm to the second end 302 of the first support arm. Similarly, the second support arm 4 extends downwardly generally toward the outside of the vehicle 2000 in the direction from the first end 41 of the second support arm to the second end 42 of the second support arm. In the extended position, the first support arm 3 is located below the second support arm 4.

[0157] When the pedal mounting assembly 100 moves between the retracted position and the extended position, the first support arm 3 and the second support arm 4 have a certain swing angle. In some examples, the swing angle of the first line S1 is greater than or equal to 105 degrees and less than or equal to 120 degrees from the retracted position to the extended position. Since the first line S1 can be generally parallel to the second line S2, the swing angle of the second line S2 is also greater than or equal to 105 degrees and less than or equal to 120 degrees.

[0158] The inventor found through experimental research that when the swing angle of the first line S1 before the retracted position to the extended position is within the above range, the action process of the pedal mounting assembly 100 is more reasonable, and the mechanical performance is better.

[0159] For example, the swing angle of the first line S1 (the second line S2) can be 105 degrees, 1110 degrees, 115 degrees, 120 degrees.

[0160] As shown in Figures 17 to 20 , the telescopic pedal device 1000 of some other embodiments of the utility model comprises at least one pedal 200 and a plurality of pedal mounting assemblies 100. The pedal 200 has a tread surface 2006, among the pedal supports 2 of adjacent pedal mounting assemblies 100, the first side 201 of one pedal support 2 is opposite to the second side 202 of another pedal support 2, and the pedal 200 is connected between the first side 201 of one pedal support 2 and the second side 202 of another pedal support 2, so as to move the pedal 200 between the extended position and the retracted position of the pedal mounting assembly 100.

[0161] According to the telescopic pedal device 1000 of the utility model embodiment, since the pedal 200 is connected between the first side 201 of one pedal support 2 and the second side 202 of another pedal support 2, the overall thickness of the pedal support 2 and the pedal 200 in the up-down direction after assembly is small, the required installation space is small, and the pedal mounting assembly 100 is particularly suitable for vehicles 2000 with low chassis.

[0162] In an example, as shown in Figure 19As shown, the pedal mounting assembly 100 includes a first pedal mounting assembly 110 and a second pedal mounting assembly 120. The first end 2001 of the pedal 200 is connected to the first side 201 of the pedal support 2 of the first pedal mounting assembly 110, and the second end 2002 of the pedal 200 is connected to the second side 202 of the pedal support 2 of the second pedal mounting assembly 120. In this example, the retractable pedal device 1000 includes only two sets of pedal mounting assemblies 100 (i.e., the first pedal mounting assembly 110 and the second pedal mounting assembly 120), which are respectively arranged on both sides of the pedal 200 along the length of the pedal.

[0163] In another example, such as Figure 17 and Figure 18 As shown, the pedal mounting assembly 100 includes a first pedal mounting assembly 110, a second pedal mounting assembly 120, and at least one intermediate pedal mounting assembly 130 located between the first pedal mounting assembly 110 and the second pedal mounting assembly 120. The pedal 200 includes at least a first pedal 210 and a second pedal 220. A first end 2001 of the first pedal is connected to a first side 201 of the pedal support 2 of the first pedal mounting assembly 110, and a second end 2002 of the first pedal is connected to a second side 202 of the pedal support 2 of an intermediate pedal mounting assembly 130. A first end 2001 of the second pedal is connected to a first side 201 of the pedal support 2 of one or more intermediate pedal mounting assemblies 130, and a second end 2002 of the second pedal is connected to a second side 202 of the pedal support 2 of the second pedal mounting assembly 120.

[0164] like Figure 17 and Figure 18 As shown, multiple pedal mounting assemblies 100 (first pedal mounting assembly 110, second pedal mounting assembly 120, and intermediate pedal mounting assembly 130) and multiple pedals 200 (first pedal 210 and second pedal 220) are arranged alternately along the length of the pedals 200. The intermediate pedal mounting assembly 130 is located between the first pedal mounting assembly 110 and the second pedal mounting assembly 120. The first side 201 and the second side 202 of the pedal support 2 of the intermediate pedal mounting assembly 100 are connected to two pedals 200 (first pedal 210 and second pedal 220) respectively, thereby extending the length of the telescopic pedal device 1000 and expanding its application range.

[0165] like Figure 24 and Figure 25As shown, each of the first pedal mounting assembly 110 and the second pedal mounting assembly 120 comprises an end cover 300, the end cover 300 of the first pedal mounting assembly 110 is connected with the second side 202 of the pedal support 2 of the first pedal mounting assembly 110, and the end cover 300 of the second pedal mounting assembly 120 is connected with the first side 201 of the pedal support 2 of the second pedal mounting assembly 120. That is, when the support matching part 25 of the first side 201 of the pedal support 2 is connected with the pedal 200, the end cover 300 can be arranged on the support matching part 25 of the second side 202 of the pedal support 2. Similarly, when the support matching part 25 of the second side 202 of the pedal support 2 is connected with the pedal 200, the end cover 300 can be arranged on the support matching part 25 of the first side 201 of the pedal support 2. Thus, the pedal supports 2 of the pedal mounting assemblies 100 at different positions are universal to each other, and the production and assembly costs are reduced.

[0166] The second side 202 of the pedal support 2 of the first pedal mounting assembly 110 and the first side 201 of the pedal support 2 of the second pedal mounting assembly 120 are respectively provided with a support matching part 25. The end cover 300 is provided with an end cover matching part 3001 which is engaged with the support matching part 25.

[0167] Further, as shown, Figures 17 to 19 the upper surface 3003 of the end cover, the tread surface 2006 of the pedal 200 and the upper surface 29 of the pedal support are generally flush, and the outer surface 3004 of the end cover, the outer surface 2007 of the pedal and the outer surface 203 of the pedal support are generally flush. On the one hand, the integrity of the pedal 200, the pedal support 2 and the end cover 300 after being connected is good. On the other hand, the user can also step on the end cover 300, thereby the space utilization of the telescopic pedal device 1000 can be improved, and the structure design is compact.

[0168] Some other specific embodiments of the telescopic pedal device 1000 are described below.

[0169] As shown, Figures 1 to 27 the telescopic pedal device 1000 of the embodiment of the utility model comprises a pedal 200 and a plurality of pedal mounting assemblies 100. The pedal 200 has a first end and a second end in the length direction thereof, the pedal 200 has a tread surface 2006, and the pedal 200 is connected between adjacent pedal mounting assemblies 100.

[0170] The pedal mounting assembly 100 comprises a mounting bracket 1, a pedal bracket 2 and at least one pair of support arms (e.g. a first support arm 3 and a second support arm 4). The pedal bracket 2 has an inwardly opening pedal bracket slot 21, and the pedal bracket 2 has a first side 201 and a second side 202 facing away from each other in the length direction of the pedal 200. The at least one pair of support arms are respectively pivotally connected with the mounting bracket 1 and the pedal bracket 2 to move the pedal 200 between an extended position and a retracted position.

[0171] In the adjacent two pedal mounting assemblies 100, the first side 201 of the pedal bracket 2 of one pedal mounting assembly 100 and the second side 202 of the pedal bracket 2 of the other pedal mounting assembly 100 face each other in the length direction of the pedal 200, the first end 2001 of the pedal is connected with the first side 201 of the pedal bracket 2 of one pedal mounting assembly 100, and the second end 2002 of the pedal is connected with the second side 202 of the pedal bracket 2 of the other pedal mounting assembly 100.

[0172] In other words, the adjacent two pedal mounting assemblies 100 are respectively arranged on both sides of the pedal 200 in the length direction of the pedal. Thus, the assembly of the telescopic pedal device 1000 is simple, and the overall thickness of the pedal bracket 2 and the pedal 200 after assembly is small in the extended position, especially in the retracted position, so that the required installation space is smaller, so that the pedal mounting assembly 100 can be better applied to vehicles 2000 with lower chassis.

[0173] As shown in Figures 13 to 16 , in the extended position, the length of the first support arm 3 located in the pedal bracket slot 21 is L3a, and the length of the second support arm 4 located in the pedal bracket slot 21 is L4a, in the retracted position, the length of the first support arm 3 located in the pedal bracket slot 21 is L3b, and the length of the second support arm 4 located in the pedal bracket slot 21 is L4b, wherein L3a is less than L3b, and L4a is less than L4b. Wherein in the retracted position, the tread surface 2006 of the pedal 200 is generally horizontal and adjacent to the bottom surface 101 of the mounting bracket.

[0174] As shown in Figure 14 , in the retracted position, the length of the second support arm 4 located in the pedal bracket slot 21 is L4b, wherein L4a is less than L4b.

[0175] Optionally, as shown in Figure 19 and Figure 20 , the first end 2001 of the pedal 200 and the second end 2002 of the pedal are respectively provided with a pedal matching part 2003, and the first side 201 of the pedal bracket 2 of one pedal mounting assembly 100 and the second side 202 of the pedal bracket 2 of the other pedal mounting assembly 100 are respectively provided with a bracket matching part 25, and the pedal matching part 2003 and the bracket matching part 25 are engaged with each other.

[0176] Optionally, one of the pedal engaging portion 2003 and the support engaging portion 25 comprises at least one engaging hole, and the other of the pedal engaging portion 2003 and the support engaging portion 25 comprises at least one prism, the cross section of the engaging hole and the cross section of the prism are non-circular and adapted to each other, and the prism is inserted and engaged in the engaging hole. In this way, the structural strength of the pedal support 2 as a whole can be improved, so that the pedal support 2 is more reliable in connection with the pedal 200, and is convenient to disassemble and assemble.

[0177] In some embodiments, as shown in Figure 16 the first end 301 of the first support arm is pivotable relative to the mounting support 1 about a first pivot axis X1, the second end 302 of the first support arm is pivotable relative to the pedal support 2 about a third pivot axis X3, the first end 41 of the second support arm is pivotable relative to the mounting support 1 about a second pivot axis X2, and the second end 42 of the second support arm is pivotable relative to the pedal support 2 about a fourth pivot axis X4, wherein in a retracted position, the third pivot axis X3 and the fourth pivot axis X4 are located within an area defined by the outer peripheral contour of the pedal 200 in a plane orthogonal to the length direction of the pedal 200, and the outer edge 2004 of the pedal is located inward of the second pivot axis X2.

[0178] As shown in Figure 14 and Figure 16 , in the retracted position, the outer edge 2004 of the pedal is located more inwardly than the position of the second pivot axis X2. Since the third pivot axis X3 and the fourth pivot axis X4 are located within an area defined by the outer peripheral contour of the pedal 200, the structure of the retractable pedal device 1000 can be made more compact, and the overall space occupied is smaller.

[0179] Optionally, as shown in Figure 14 and Figure 16 , in the retracted position, the outer edge 2004 of the pedal is located inward of the first pivot axis X1 in a plane orthogonal to the length direction of the pedal 200 (i.e. in a plane orthogonal to the first pivot axis X1). Alternatively, in the retracted position, the outer edge 2004 of the pedal is located outward of the first pivot axis X1 and adjacent to the first pivot axis X1 in a plane orthogonal to the length direction of the pedal 200. In other words, in the retracted position, the outer edge 2004 of the pedal is generally located between the first pivot axis X1 and the second pivot axis X2. Preferably, the distance between the outer edge 2004 of the pedal and the first pivot axis X1 is less than 5 mm.

[0180] Further specific embodiments of the retractable pedal device 1000 are described below.

[0181] As shown in Figures 1 to 27As shown, the telescopic pedal device 1000 of the embodiment of the present application comprises a pedal 200, a first support arm 3 and a second support arm 4. The pedal 200 has a tread surface 2006 and is movable between an extended position and a retracted position, the first support arm 3 is connectable to the bottom of the vehicle body 20001 of the vehicle 2000 and is pivotable about a first pivot axis X1, the first support arm 3 is connected to the pedal 200 and is pivotable about a third pivot axis X3, the second support arm 4 is connectable to the bottom of the vehicle body 20001 of the vehicle 2000 and is pivotable about a second pivot axis X2, the second support arm 4 is connected to the pedal 200 and is pivotable about a fourth pivot axis X4, wherein in a plane orthogonal to the first pivot axis X1, in the retracted position, the third pivot axis X3 and the fourth pivot axis X4 are located within the area defined by the outer peripheral contour of the pedal 200.

[0182] According to the telescopic pedal device 1000 of the embodiment of the present application, in the retracted position, the third pivot axis X3 and the fourth pivot axis X4 are located within the area defined by the outer peripheral contour of the pedal 200, the distance of the telescopic pedal device 1000 from the ground is farther, thereby the required installation space of the telescopic pedal device 1000 is smaller, and the passability of the vehicle is improved.

[0183] Optionally, as shown in Figure 13 and Figure 14 in the plane orthogonal to the first pivot axis X1, the third pivot axis X3 is adjacent to the inner edge 2005 of the pedal. Thus the telescopic device is more compact in structure and has a smaller height dimension in the retracted position.

[0184] As shown in Figures 4 to 7 the first end 301 of the first support arm 3 is pivotable about the first pivot axis X1, the second end 302 of the first support arm is pivotable about the third pivot axis X3, the first end 41 of the second support arm 4 is pivotable about the second pivot axis X2, and the second end 42 of the second support arm is pivotable about the fourth pivot axis X4.

[0185] The first end 301 of the first support arm is provided with a receiving groove 3011, and the first end 41 of the second support arm is accommodated in the receiving groove 3011, so that the first pivot axis X1 of the first end 301 of the first support arm and the second pivot axis X2 of the second end 42 of the second support arm are closer, thereby the first support arm 3 and the second support arm 4 are more compact in structure.

[0186] In the direction parallel to the first pivot axis X1, the pedal 200 is arranged side by side with the first support arm 3 and the second support arm 4, so that the projection of the pedal 200 in the horizontal plane does not overlap the projection of the first support arm 3 and the second support arm 4 in the horizontal plane. Thus the overall thickness of the telescopic pedal device 1000 after retraction can be reduced.

[0187] The embodiment of the utility model discloses a retractable pedal device 1000, by the projection of pedal 200 in the horizontal plane with the projection of first support arm 3 and second support arm 4 in the horizontal plane does not overlap, to make first support arm 3 (second support arm 4) with the pivot connection structure of pedal 200 with pedal 200 generally be located at the same horizontal height, thereby can reduce the overall thickness of retractable pedal device 1000 after retracting.

[0188] Below some further specific embodiments of the retractable pedal device 1000 are described.

[0189] As Figures 1 to 27 shown, the embodiment of the utility model discloses a retractable pedal device 1000 includes pedal 200, first support arm 3 and second support arm 4. Pedal 200 has the tread surface 2006, and pedal 200 is movable between the extended position and the retracted position, first support arm 3 can be connected to the vehicle body bottom 20001 of vehicle 2000 and pivotable around the first pivot axis X1, first support arm 3 is connected with pedal 200 and pivotable around the third pivot axis X3, second support arm 4 can be connected to the vehicle body bottom 20001 of vehicle 2000 and pivotable around the second pivot axis X2, second support arm 4 is connected with pedal 200 and pivotable around the fourth pivot axis X4.

[0190] The second pivot axis X2 is located outside the first pivot axis X1, and the fourth pivot axis X4 is located outside the third pivot axis X3. In the plane orthogonal to the first pivot axis X1, the outer edge 2004 of the pedal is located inside the second pivot axis X2 in the retracted position.

[0191] According to the embodiment of the utility model discloses a retractable pedal device 1000, because in the plane orthogonal to the first pivot axis X1, the outer edge 2004 of the pedal in the retracted position is located inside the second pivot axis X2, in the retracted position, the first support arm 3 and the second support arm 4 are more compactly overlapped, not only reduce the size of retractable pedal device 1000 along the inside and outside direction, and pedal 200 can be more close to the upper in the retracted position, to be far from the ground.

[0192] Optionally, in the plane orthogonal to the first pivot axis X1, the outer edge 2004 of the pedal is located inside the first pivot axis X1 in the retracted position.

[0193] In the plane orthogonal to the first pivot axis X1, the outer edge 2004 of the pedal is located outside the first pivot axis X1 and adjacent to the first pivot axis X1 in the retracted position. Preferably, the distance between the outer edge 240 of the pedal support and the first pivot axis X1 is less than 5 mm.

[0194] Further, as Figure 19As shown, the telescopic pedal device 1000 further comprises a pedal support 2, the second end 302 of the first support arm is pivotally connected with the pedal support 2, the second end 42 of the second support arm is pivotally connected with the pedal support 2, and the pedal 200 is arranged side by side with the pedal support 2 in the length direction of the pedal 200, so that the projection of the pedal 200 in the horizontal plane and the projection of the pedal support 2 in the horizontal plane do not overlap with each other.

[0195] The pedal support 2 and the pedal 200 are located at the same horizontal height. Therefore, the overall thickness of the pedal support 2 and the pedal 200 after assembly can be reduced, a part of the pedal support 2 can be stepped on by the user, so that the telescopic pedal device 1000 has a compact structure, the space utilization is improved, and the use effect is better.
