In some embodiments of the present invention, as shown in fig. 2-7, the sliding chute assembly 21 comprises a sliding chute 211, the sliding chute 211 is fixedly connected with the inner surface of the footrest 11, and one end of the sliding chute 211 away from the leg and foot portion 5 of the driver is an open end. As shown in fig. 2 to 5, the linkage assembly 22 includes a bending connecting rod 221, a sliding member 222 and a connecting member 223, the two ends of the bending connecting rod 221 are respectively provided with the sliding member 222 and the connecting member 223, the connecting member 223 is fastened to the position limiting assembly 23, the sliding member 222 is disposed at a position of the sliding slot 211 close to the opening end of the sliding slot 211, and the sliding member 222 can move in a direction away from the opening end of the sliding slot 211 relative to the sliding slot 211 when the vehicle is collided. The bending link 221 includes a first link portion 2211 and a second link portion 2212, wherein an end of the second link portion 2212 away from the first link portion 2211 is bent toward the limiting assembly 23. The slider 222 is disposed on an end of the first link portion 2211 remote from the second link portion 2212, and the link 223 is disposed on an end of the second link portion 2212 remote from the first link portion 2211. The linkage assembly 22 further includes a link bracket 224, the link bracket 224 is disposed at the intersection of the first and

second link portions

2211 and 2212, and the link bracket 224 is fixedly connected to the inner surface of the mounting plate 13. The inner surface of the mounting plate 13 refers to the side of the mounting plate 13 close to the footrest 11. The chute assembly 21 further comprises a chute baffle 212, and the chute baffle 212 is tightly connected with the open end of the chute 211. As shown in fig. 3, 4, and 7, the chute 211 is provided with a chute concave portion 2111, and the snap ring 213 is provided in the chute concave portion 2111. The slider 222 is disposed within the chute 211, and the slider 222 is disposed between the snap ring 213 and the chute shield 212.

Preferably, the sliding member 222 is a spherical sliding member, the spherical sliding member is in point contact with the sliding groove 211, the friction force is small, the force transmission is reliable, and when the sliding member 222 or the sliding groove 211 needs to be replaced, the sliding member is easy to detach and replace, and the maintenance cost is reduced.

As shown in fig. 7, a snap ring limiting protrusion 2131 is provided on the inner side of the snap ring 213, that is, the snap ring limiting protrusion 2131 is located on the side of the snap ring 213 close to the slider 222. The snap ring 213 itself generates an initial movement resistance to the slider 222 that prevents it from sliding along the slide groove 211; the snap ring limiting protrusion 2131 is to add an initial motion resistance to the slider 222 based on the reverse force provided by the snap ring 213, so as to prevent the slider 222 from moving mistakenly due to the force exerted on the footrest 11 by the driver's foot 52 when the collision strength is not reached.

When a collision event occurs, the driver's foot 52 applies a load to the footrest 11, the energy absorbing assembly 12 is extruded and deformed along with the load applied by the driver's foot 52 to absorb the kinetic energy at the driver's leg 5, when the energy absorbing assembly 12 is extruded and deformed downward, the footrest 11 is also moved downward along with the energy absorbing assembly 12, at this time, the sliding member 222 of the linkage assembly 22 is subjected to an acting force extruding toward the snap ring 213, when the energy absorbing assembly 12 is deformed to a certain extent, the sliding member 222 breaks the initial movement resistance of the snap ring 213, and the sliding member 222 is moved away from the opening end of the slide groove 211 relative to the slide groove 211, the first link portion 2211 is also moved along the slide groove 211 under the driving of the sliding member 222, and under the action of the first link portion 2211 and the link bracket 224, the second link portion 2212 drives the limit assembly 23 to move toward the driver's leg 5 according to the lever principle, to limit the displacement of the driver's legs 5 in the forward stroke. Therefore, the link assembly 22 of the blocking device 2 of the driver leg and foot protection structure of the present invention can move relative to the chute assembly 21 of the blocking device 2 when the vehicle is collided, so that the limit assembly 23 of the blocking device 2 approaches to the direction of the driver leg and foot 5, and further the movement of the leg and foot 5 is limited, and the displacement of the driver leg and foot 5 towards the front cabin floor can be limited by the blocking device 2 at the initial stage of the collision event, and the impact force is prevented from being absorbed and damaged when the collision energy is too large at the later stage after the driver leg and foot 5 is displaced in the forward direction, and the damage to the driver leg and

foot

51 and 52 at the time of the vehicle collision can be greatly reduced, and further the driver leg and foot 5 can be effectively protected, and the safety can be improved.

In some embodiments of the present invention, as shown in fig. 6, the position-limiting assembly 23 includes a position-limiting member 231 and a fastening member 232, at least one mounting slot 2310 is disposed on the position-limiting member 231, a connecting member 223 of the linkage assembly 22 is disposed in the mounting slot 2310, and the connecting member 223 is fastened to the position-limiting member 231 by the fastening member 232. When the plurality of mounting grooves 2310 are formed in the limiting member 231, the mounting grooves 2310 for placing the connecting members 223 of the linkage assembly 22 can be selected according to the area, shape and the like of the front cabin floor of the vehicle during actual mounting, so that the vehicle can be adapted to vehicles of more vehicle types, and the compatibility and universality of the leg and foot protection structure of the driver can be improved.

In some embodiments of the present invention, as shown in FIGS. 1, 2, 8 and 9, energy absorber assembly 12 is comprised of two energy absorbing plates 120 symmetrically disposed between footrest 11 and mounting plate 13. The energy absorbing plate 120 has an accordion structure, and when a collision occurs, the energy absorbing plate 120 having the accordion structure sufficiently absorbs collision energy of the vehicle by collapsing and deforming, thereby attenuating collision force to the driver's leg and foot portion 5 and protecting the driver's leg and foot portion 5 from being damaged by fracture or the like.

The energy absorbing plate 120 is formed with a first bend 121, a second bend 122, and a third bend 123 in this order along the footrest 11 toward the mounting plate 13. A first energy-absorbing hole 1210 is arranged on the first bending part 121, a second energy-absorbing hole 1220 is arranged on the second bending part 122, a third energy-absorbing hole 1230 is arranged on the third bending part 123, and the area of the first energy-absorbing hole 1210, the area of the second energy-absorbing hole 1220 and the area of the third energy-absorbing hole 1230 are decreased progressively. Since the area of the first energy-absorbing hole 1210, the area of the second energy-absorbing hole 1220, and the area of the third energy-absorbing hole 1230 decrease, the energy required for the first bent portion 121, the second bent portion 122, and the third bent portion 123 to be deformed by collapsing increases. When a collision occurs, if the driver is of a small size, the driver has little energy due to inertia or the like at the time of the collision, and the first bent portion 121 is deformed to be collapsed first to absorb energy. When the driver is of a medium body type, the energy generated by the driver due to inertia or the like at the time of collision is larger than that of a small body type, and the second bent portion 122 is also deformed to be collapsed and is absorbed in addition to the first bent portion 121. When the driver is a large driver, the driver generates a large amount of energy due to inertia or the like when a collision occurs, and the third bent portion 123 is deformed to be collapsed and absorbed in addition to the first bent portion 121 and the second bent portion 122. Therefore, the leg and foot protection structure for the driver can meet different degrees of collapsing deformation required by drivers with different body types (different heights and weights) under different collision conditions, achieves energy absorption protection for the leg and foot parts 5 of different drivers during collision, and obviously improves the compatibility and universality of protection for the drivers with different body types. Meanwhile, in the collision process, the footrest device 1 of the driver leg and foot protection structure provided by the invention has the energy absorption assembly 12 which can deform adaptively according to the body shape of the driver so as to absorb the kinetic energy of the driver leg and foot 5, and the footrest 11 only plays a role in force transmission in the process, so that the footrest 11 is not easy to damage in the collision process, and further, the secondary damage to the driver leg and foot is avoided.

Of course, in consideration of protection of the driver's leg 5 during a collision, for example, to further reduce the collision force applied to the leg 5, those skilled in the art can flexibly set the number and size of the curved portions and the energy absorbing holes provided in the energy absorbing plate 120, thereby achieving better absorption of the collision force and sufficiently protecting the driver's leg 5. Thus, the driver's leg and foot protection structure according to the present invention has a footrest function to improve the comfort of the vehicle, and also can sufficiently absorb the energy generated during the vehicle collision by the collapsing deformation of the energy absorbing plate 120, thereby attenuating the collision force received by the driver's leg and foot 5 during the collision and protecting the driver's leg and foot 5 from being damaged.

According to a second aspect of the present invention, there is provided a vehicle including the driver's leg and foot protecting structure of any one of the above embodiments.

According to the vehicle provided by the second aspect of the present invention, since the leg and foot protection structure for the driver according to the above embodiment of the present invention has the above technical effects, the vehicle according to the embodiment of the present invention also has corresponding technical effects, that is, the vehicle has the advantages of high compatibility, strong versatility, high safety, strong operability, and strong reliability.
