[0052] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0053] like Figures 1 to 4 As shown in the embodiment, a high-load-bearing double-layer intelligent telescopic side guard bar is provided, which can be applied to automobiles.

[0054] In some embodiments, the high-load-bearing double-layer intelligent telescopic side guard bar may have a folded state 1001 and an unfolded state 1002. Additionally, the high-load-bearing double-layer intelligent telescopic side guard bar also has intersecting first direction M and second direction N. In some embodiments, the first direction M may be parallel to the height direction of the vehicle, and the second direction N may be parallel to the width direction of the vehicle.

[0055] In some embodiments, the high-load-bearing double-layer intelligent telescopic side guardrail may include a base 100, a drive member 400, a connecting seat 300, a pedal assembly 500, and at least two sets of linkage assemblies 200. The base 100 can be used to connect to the vehicle body. The drive member 400 can be mounted on the base 100. One end of the linkage assembly 200 is rotatably connected to the base 100, and the connecting seat 300 is rotatably connected to the end of the linkage assembly 200 away from the base 100. One set of linkage assemblies 200 can be driveably connected to the drive member 400, and the drive member 400 can drive this set of linkage assemblies 200 to move, and the connecting seat 300 can drive the other sets of linkage assemblies 200 to move synchronously.

[0056] In some embodiments, the pedal assembly 500 includes a first pedal 510 and a second pedal 520. The first pedal 510 can be connected to the base 100, and the second pedal 520 can be connected to the connecting seat 300. When the high-load-bearing double-layer intelligent telescopic side guard bar is in the deployed state 1002, the first pedal 510 and the second pedal 520 can be offset in a first direction M, and the first pedal 510 and the second pedal 520 are also offset in a second direction N.

[0057] During use, the drive unit 400 can drive the linkage assembly 200 connected to it to move, causing the linkage assembly 200 to unfold or fold. During the unfolding and folding of this linkage assembly 200, other linkage assemblies 200 can be simultaneously unfolded or folded. Furthermore, the linkage assembly 200 can drive the connecting seat 300 and the second pedal 520 to move synchronously. When the high-load-bearing double-layer intelligent telescopic side guardrail is in the unfolded state 1002, the first pedal 510 and the second pedal 520 will be misaligned in both the first direction M and the second direction N. This creates a two-stage pedal system, reducing the user's stride and facilitating entry and exit, thus improving user comfort.

[0058] like Figure 3 , Figures 5 to 8 As shown, in some embodiments, the base 100 may include an integral base body 110 and a connecting arm 120. The connecting arm 120 may protrude from one side relative to the base body 110. The base body 110 may be fixedly connected to the vehicle body by means of bolts or welding.

[0059] In some embodiments, a connecting plate portion 121 may be provided at the end of the connecting arm 120 away from the base body 110, and the connecting plate portion 121 may protrude from the side of the connecting arm 120 opposite to the base body 110. The first pedal 510 may be fixedly connected to the connecting plate portion 121 by means of bolt connection or welding.

[0060] like Figure 5 and Figure 6As shown, in some embodiments, the high-load-bearing double-layer intelligent telescopic side guard bar may include two sets of connecting rod assemblies 200. Both sets of connecting rod assemblies 200 are connected between the base 100 and the connecting seat 300, and are both located on the side of the connecting arm 120 opposite to the connecting plate portion 121. Furthermore, an included angle α may be configured between the two sets of connecting rod assemblies 200, wherein 0°≤α≤180°. Preferably, the included angle α between the two sets of connecting rod assemblies 200 may be set to 60°≤α≤120°. This improves the overall load-bearing capacity of the high-load-bearing double-layer intelligent telescopic side guard bar, enabling it to withstand greater loads. In some embodiments, the included angle α between the two sets of connecting rod assemblies 200 may be set to 90°.

[0061] In other embodiments, the included angle between the two sets of linkage assemblies 200 may also be set to 0°, 30°, 45°, 50°, 60°, 75°, 80°, 90°, 105°, 120°, 135°, 155°, 160°, 175°, 180°, or any other angle from 0° to 180°.

[0062] In other embodiments, the high-load-bearing double-layer intelligent telescopic side guard bar may further include three sets of linkage assemblies 200, all of which are connected between the base 100 and the connecting seat 300. Two sets of linkage assemblies 200 may be symmetrically arranged on both sides of another set of linkage assemblies 200, and each set forms a 90° angle with the middle set of linkage assemblies 200.

[0063] like Figure 1 , Figure 7 and Figure 8 As shown, the linkage assembly 200 may include a first link 210 and a second link 220 rotatably connected. The end of the first link 210 away from the second link 220 is rotatably connected to the base body 110 via a first pivot 610. It is understood that the end of each first link 210 away from the second link 220 is rotatably connected to the base 100. The first link 210 and the second link 220 are rotatably connected via a second pivot 620. The end of the second link 220 away from the first link 210 is rotatably connected to the connecting seat 300 via a third pivot 630. It is understood that the end of each second link 220 away from the first link 210 is rotatably connected to the connecting seat 300.

[0064] In some embodiments, one of the first rotating shafts 610 may be connected to the drive member 400 for transmission. Thus, the drive member 400 can drive the first rotating shaft 610 to rotate, and the first rotating shaft 610 can drive the first connecting rod 210 connected to it to rotate, thereby realizing the folding or unfolding action of the connecting rod assembly 200. In some embodiments, the drive member 400 may be a motor.

[0065] like Figure 4, Figure 7 , Figure 8 and Figure 10 As shown, in some embodiments, the structures of the two sets of linkage assemblies 200 can be similar. The following is a detailed description of one set of linkage assemblies 200 as an example.

[0066] In some embodiments, a first limiting protrusion 211 protrudes from the periphery of the first connecting rod 210 near the second connecting rod 220. A second limiting protrusion 221 protrudes from the periphery of the second connecting rod 220 near the first connecting rod 210. The first limiting protrusion 211 and the second limiting protrusion 221 can be arranged around the periphery of the second rotating shaft 620. It is understood that the rotation axes of the first connecting rod 210 and the second connecting rod 220 can be coaxial with the second rotating shaft 620. And the first limiting protrusion 211 can be located on the rotation path of the second limiting protrusion 221. When the high-load-bearing double-layer intelligent telescopic side guard bar is in the deployed state 1002, the first link 210 and the second link 220 can be on the same straight line. The second limiting protrusion 221 can abut against the first limiting protrusion 211 and restrict the relative rotation of the first link 210 and the second link 220, realizing the self-locking function of the link assembly 200, that is, the link assembly 200 is in a self-locking state. Correspondingly, the first limiting protrusion 211 and the second limiting protrusion 221 can cooperate to limit the stroke of the link assembly 200 when it is deployed, ensuring that the link assembly 200 can provide a large load-bearing capacity and preventing the drive component 400 from driving the first link 210 to rotate excessively, which would affect the load-bearing capacity of the link assembly 200.

[0067] In other embodiments, the drive member 400 can directly limit the travel distance of the linkage assembly 200 when it is unfolded and when it is folded. That is, after the first link 210 and the second link 220 are unfolded or folded into place, the drive member 400 stops moving, and the linkage assembly 200 stops moving.

[0068] like Figure 3 , Figure 4 , Figure 7 and Figure 9 As shown, the connecting seat 300 may be located on the side of the connecting arm 120 opposite to the connecting plate portion 121. The connecting seat 300 may include an integral connecting seat body 310 and at least two pairs of connecting ears 320. In some embodiments, the connecting seat 300 may include two pairs of connecting ears 320, which are disposed at the same end of the connecting seat body 310 and may be distributed at 90° between them. In the embodiment, in the two sets of connecting rod assemblies 200, the ends of the two second connecting rods 220 away from the first connecting rod 210 can be rotatably connected to the two pairs of connecting ears 320 one-to-one through the third rotating shaft 630.

[0069] In other embodiments, the connector 300 may also include three pairs of connector lugs 320, the same number as the link assembly 200.

[0070] In some embodiments, the second pedal 520 may be fixedly connected to the end of the connector body 310 away from the connector ear 320 by means of screw connection or welding.

[0071] like Figures 1 to 4 As shown, the first pedal 510 may be arranged parallel to the second pedal 520. In some embodiments, the second pedal 520 may be located on the side of the first pedal 510 that is closer to the ground, that is, the second pedal 520 may be arranged close to the ground side 5101 of the first pedal 510.

[0072] In some embodiments, a recessed groove 511 may be provided on the ground-near side 5101 of the first pedal 510. When the high-load-bearing double-layer intelligent telescopic side guard bar is in the folded state 1001, the second pedal 520 can be accommodated in the recessed groove 511 on the first pedal 510, realizing the folding between the first pedal 510 and the second pedal 520, reducing the space occupied by the pedal assembly 500, and preventing the high-load-bearing double-layer intelligent telescopic side guard bar from affecting the user's normal use when in the folded state 1001. At the same time, when the high-load-bearing double-layer intelligent telescopic side guard bar is in the folded state 1001, the second pedal 520 is embedded in the recessed groove 511 on the ground-near side 5101 of the first pedal 510, which can make the first pedal 510 have higher strength and improve the load-bearing capacity of the first pedal 510.

[0073] In some embodiments, the first pedal 510 has a first anti-slip texture 512 on the side facing away from the second pedal 520. The first anti-slip texture 512 may be a raised ridge or other structure. The second pedal 520 has a second anti-slip texture 521 on the side facing the first pedal 510. The second anti-slip texture 521 may be a textured surface or other structure. This increases the friction between the user pedal assembly 500 and the user's shoe sole, reducing the risk of the user slipping or other safety issues.

[0074] When the high-load-bearing double-layer intelligent telescopic side guardrail is in the deployed state 1002, the second pedal 520 can disengage from the mounting slot 511, and the second pedal 520 can separate from the first pedal 510, and be misaligned in both the first direction M and the second direction N. In some embodiments, when the high-load-bearing double-layer intelligent telescopic side guardrail is in the deployed state 1002, the second pedal 520 can be located on the side of the first pedal 510 closest to the ground, so as to achieve misalignment between the first pedal 510 and the second pedal 520 in the first direction M. Simultaneously, when the high-load-bearing double-layer intelligent telescopic side guardrail is in the deployed state 1002, the second pedal 520 can be located on the side of the first pedal 510 away from the vehicle body, that is, the second pedal 520 can extend outwards from the vehicle body, so as to achieve misalignment between the first pedal 510 and the second pedal 520 in the second direction N. When a user gets into the vehicle, they can step on the second pedal 520 first, then the first pedal 510; when getting out of the vehicle, the reverse is true.

[0075] In summary, the high-load-bearing double-layer intelligent telescopic side guardrail provided in this application embodiment can realize the folding and unfolding functions of the double-layer pedals, meeting the diverse usage needs of users. It has high load-bearing capacity, is easy to install, has a stable structure, a long service life, and a fast response speed. At the same time, it has low requirements for the chassis space of the vehicle body, and can meet the requirements of large-stroke movement even in a small space.

[0076] In addition, this application also provides a type of automobile, which may include a vehicle body and a high-load-bearing double-layer intelligent telescopic side guard bar as provided in the embodiments. The high-load-bearing double-layer intelligent telescopic side guard bar provides protection for the vehicle body, reducing the possibility of direct side collisions with the vehicle body. It also provides two-stage steps for convenient entry and exit.
