[0039] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0040] In response to the shortcomings or one of the shortcomings raised by the above-mentioned background technology, the embodiments of the present application provide a movable step, a front lower protection assembly and a vehicle, wherein the movable step can adjust the step width and has the advantage of occupying less space when folded, and can solve the problem of large space occupation caused by installing the step on the front lower protection beam.

[0041] See also Figures 1 to 3 As shown, the first aspect of the embodiment of the present application provides a movable step, including:

[0042] A step assembly, comprising a support frame 2 and pedals 1 symmetrically arranged on both sides of the support frame 2;

[0043] The driving assembly connects the supporting frame 2 and the pedals 1 on both sides, and is used to drive the pedals 1 on both sides to move closer to or away from each other.

[0044] The movable step of the embodiment of the present application includes a step assembly and a driving assembly. The step assembly includes a support frame 2 and pedals 1 symmetrically arranged on both sides of the support frame 2. The driving assembly connects the support frame 2 and the pedals 1 on both sides, and can drive the pedals 1 on both sides to move closer to or away from each other, thereby changing the overall width and adjusting the stepping width. When the pedals 1 on both sides are closest to each other, the stepping width is the smallest, and thus it has the advantage of occupying less space when folded.

[0045] Specifically, the support frame 2 of the movable step of this embodiment is rotatably installed at the front end of the front lower protective beam 10. When the movable step is flipped downward and opened to a horizontal state, the pedals 1 on both sides can be driven away from each other by the driving component, thereby widening the stepping width and improving the stepping comfort.

[0046] When the movable step is not in use, the driving assembly drives the pedals 1 on both sides to move closer to each other, thereby reducing the stepping width and further reducing the occupied space, making it convenient to flip the movable step upward and retract it, so that the movable step occupies less space in the Z direction in front of the vehicle and is not limited by the bumper above the front lower protective beam 10, i.e., it does not affect the layout of the components in front of the vehicle.

[0047] Illustratively, in this embodiment, the pedals 1 on both sides of the support frame 2 are arranged parallel to each other, and the driving component can be a telescopic rod or a folding rod connected to the pedals 1. The telescopic rod or the folding rod can drive the pedals 1 on both sides to move closer to or away from each other to adjust the stepping width.

[0048] In some optional embodiments, see Figures 1 to 3 As shown, the embodiment of the present application provides a movable step, the driving mechanism of the movable step includes a motor 3 and a lead screw 4 arranged on a support frame 2, both ends of the lead screw 4 are provided with a slider assembly, and both ends of the pedal 1 are respectively hinged with the slider assemblies on both sides through a connecting rod assembly;

[0049] The motor 3 drives the lead screw 4 to rotate, and the slider assemblies on both sides move closer to and farther from each other on the lead screw 4 synchronously, and the pedals 1 on both sides move closer to and farther from each other through the transmission of the connecting rod assembly.

[0050] The driving mechanism of the movable step in the embodiment of the present application includes a motor 3 and a screw 4, a slider assembly is screwed onto the screw 4, a connecting rod assembly is hinged at the end of the slider assembly, and the end of the connecting rod assembly away from the slider assembly is hinged to the pedal 1 assembly. In this embodiment, both ends of the pedal 1 are hinged with connecting rod assemblies, thereby achieving stable support for the pedal 1.

[0051] Specifically, the motor 3 drives the lead screw 4 to rotate, so that the slider assembly on the lead screw 4 drives the connecting rod assembly to swing, and the connecting rod assemblies hinged at both ends of the pedal 1 swing toward the supporting frame 2, thereby driving the pedals 1 on both sides of the supporting frame 2 to move closer to each other; when the pedals 1 on both sides of the supporting frame 2 need to move away from each other, the motor 3 can be used to drive the lead screw 4 to rotate in the opposite direction.

[0052] Exemplarily, the motor 3 in this embodiment is fixedly mounted on the support frame 2, a main gear is fixedly mounted on the output end of the motor 3, a sub-gear is fixedly mounted on one end of the lead screw 4, the main gear is meshed with the sub-gear, and the motor 3 drives the sub-gear to rotate through the main gear, thereby driving the lead screw 4 to rotate.

[0053] In some optional embodiments, see Figures 1 to 3 As shown, an embodiment of the present application provides a movable step, wherein a slider assembly of the movable step comprises a first slider 5 and a second slider 6 threadedly connected to a lead screw 4, and a connecting rod assembly comprises a first connecting rod 7 hinged to the first slider 5, and a second connecting rod 8 hinged to the second slider 6;

[0054] The first connecting rod 7 and the second connecting rod 8 are both hinged to the pedal 1 at one end away from the lead screw 4 , and the threads on the lead screw 4 respectively adapted to the first slider 5 and the second slider 6 have opposite rotation directions.

[0055] The slider assembly of the movable step in the embodiment of the present application includes a first slider 5 and a second slider 6 threadedly connected to the screw 4, and the connecting rod assembly includes a first connecting rod 7 and a second connecting rod 8; one end of the first connecting rod 7 is hinged to the first slider 5, and the other end is hinged to the end of the pedal 1; one end of the second connecting rod 8 is hinged to the second slider 6, and the other end is hinged to the end of the pedal 1.

[0056] It should be noted that, in this embodiment, the threads on the lead screw 4 that are respectively adapted to the first slider 5 and the second slider 6 have opposite rotation directions, and the first connecting rod 7 and the second connecting rod 8 are hinged at one end away from the supporting frame 2 at the same position at the end of the pedal 1. The first connecting rod 7, the second connecting rod 8 and the supporting frame 2 form a triangle, which can increase the structural stability and ensure the pedaling reliability of the pedal 1.

[0057] Specifically, the motor 3 drives the lead screw 4 to rotate. Since the threads on the lead screw 4 that are respectively adapted to the first slider 5 and the second slider 6 have opposite rotation directions, the first slider 5 and the second slider 6 at the ends of the lead screw 4 can approach each other. The first slider 5 and the second slider 6 respectively drive the first connecting rod 7 and the second connecting rod 8 to swing outward, so that the first connecting rod 7 and the second connecting rod 8 synchronously drive the pedals 1 on both sides away from the supporting frame 2, and the distance between the pedals 1 on both sides becomes larger, thereby widening the pedaling width and improving the pedaling comfort.

[0058] When the movable step is not needed, the motor 3 drives the screw 4 to rotate in the opposite direction. Since the threads on the screw 4 that are respectively adapted to the first slider 5 and the second slider 6 are in opposite directions, the first slider 5 and the second slider 6 at the ends of the screw 4 can move away from each other. The first slider 5 and the second slider 6 respectively drive the first connecting rod 7 and the second connecting rod 8 to swing toward the screw 4, so that the first connecting rod 7 and the second connecting rod 8 synchronously drive the pedals 1 on both sides to approach the supporting frame 2, and the distance between the pedals 1 on both sides becomes smaller, thereby reducing the stepping width and reducing the occupied space.

[0059] In some optional embodiments, see Figures 1 to 3 As shown, an embodiment of the present application provides a movable step, the lead screw 4 of the movable step is rotatably connected to the inside of the support frame 2, and the support frame 2 is respectively provided with strip guide holes 9 for the first slider 5 and the second slider 6 to extend out.

[0060] The interior of the support frame 2 of the movable step in the embodiment of the present application is a hollow structure, and the lead screw 4 is rotatably installed inside the support frame 2 through a bearing, which can increase the strength of the support frame 2 and ensure the reliability of the movable step.

[0061] At the same time, in order to guide and limit the first slider 5 and the second slider 6, strip guide holes 9 are respectively opened at the positions corresponding to the first slider 5 and the second slider 6 on the support frame 2, and the first slider 5 and the second slider 6 respectively extend the strip guide holes 9 at the corresponding positions, thereby facilitating the hinged installation of the first connecting rod 7 and the second connecting rod 8 on the first slider 5 and the second slider 6.

[0062] See also Figures 4 to 8 As shown, the second aspect of the embodiment of the present application provides a front lower protection assembly, including:

[0063] Front lower protective beam 10;

[0064] The movable step of any one of the above items is rotatably mounted on the front lower protective beam 10.

[0065] Any of the above-mentioned movable steps is rotatably mounted on the front lower protection beam 10 of the front lower protection assembly of the embodiment of the present application. Since the movable step can adjust the stepping width, it has the advantage of occupying less space when folded up. When the movable step is flipped up and folded up, the movable step occupies less space front and back and up and down. Therefore, the problem of large space occupation caused by installing a step on the front lower protection beam 10 can be solved.

[0066] Specifically, the support frame 2 of the movable step of this embodiment is rotatably installed at the front end of the front lower protective beam 10. When the movable step is flipped downward and opened to a horizontal state, the pedals 1 on both sides can be driven away from each other by the driving component, thereby widening the stepping width and improving the stepping comfort.

[0067] When the movable step is not in use, the driving assembly drives the pedals 1 on both sides to move closer to each other, thereby reducing the stepping width and further reducing the occupied space, making it convenient to flip the movable step upward and retract it, so that the movable step occupies less space in the Z direction in front of the vehicle and is not limited by the bumper above the front lower protective beam 10, i.e., it does not affect the layout of the components in front of the vehicle.

[0068] In the second aspect, in some optional embodiments: see Figures 4 to 8 As shown, an embodiment of the present application provides a front lower protection assembly, a hinge seat 11 is fixedly installed on the front end surface of the front lower protection beam 10 of the front lower protection assembly, a movable step is hinged to the hinge seat 11 through a pin shaft, a positioning block 12 is provided on the hinge seat 11, and when the movable step is flipped downward to open, the movable step rests on the positioning block 12.

[0069] A hinge seat 11 is fixedly installed on the front end surface of the front lower protection beam 10 of the front lower protection assembly of the embodiment of the present application, and the support frame 2 of the movable step is hinged on the hinge seat 11 through a pin shaft. A positioning block 12 is fixedly connected to the hinge seat 11. When the movable step is flipped downward to open, the support frame 2 of the movable step can abut against the positioning block 12, thereby keeping the movable step in a horizontal open position to facilitate people to step on it.

[0070] For example, in this embodiment, the support frame 2 on the movable step is U-shaped, and two hinge seats 11 are fixedly installed on the front end surface of the corresponding front lower protective beam 10. The cross section of the hinge seat 11 is U-shaped. During installation, the two ends of the support frame 2 extend into the inner side of the hinge seats 11 on both sides respectively, and then the pin shaft is installed. The pin shaft passes through the hinge seat 11 and the end of the support frame 2, and then the support frame 2 is hinged to the hinge seat 11.

[0071] The inner side of the hinge seat 11 is fixedly connected with a positioning block 12 located below the pin shaft. The positioning block 12 can limit the downward flipping range of the support frame 2. When the movable step is flipped downward and opened to a horizontal position, the support frame 2 of the movable step just rests on the positioning block 12, thereby keeping the movable step in a horizontal open position for convenience of people stepping on it.

[0072] In the second aspect, in some optional embodiments: see Figures 4 to 8 As shown, an embodiment of the present application provides a front lower protection assembly, wherein the upper end of the hinge seat 11 of the front lower protection assembly is bent in a direction away from the front lower protection beam 10 to form a limiting surface 13, an elastic clamping seat 14 is provided on the limiting surface 13, and a clamping column 15 is provided on the movable step. When the movable step is flipped upward and retracted, the clamping column 15 is clamped into the elastic clamping seat 14.

[0073] The upper end of the hinge seat 11 of the front lower protection assembly of the embodiment of the present application is bent in the direction away from the front lower protection beam 10 to form a limiting surface 13. The limiting surface 13 can limit the range of the movable step to flip upward, thereby preventing the pedal 1 on the movable step from colliding with the front lower protection beam 10 when the movable step is flipped upward and retracted, thereby improving the reliability of the movable step.

[0074] Furthermore, by fixing an elastic clamping seat 14 on the limiting surface 13 and fixing a clamping column 15 on the support frame 2 of the movable step, when the movable step is turned up and retracted, the clamping column 15 can move with the support frame 2 and be clamped into the elastic clamping seat 14, which can solve the problem of fixing the movable step when it is turned up and retracted. When the movable step needs to be used, the clamping column 15 can move with the support frame 2 and be separated from the elastic clamping seat 14 by turning the movable step downward.

[0075] For example, the elastic holder 14 in this embodiment is a U-shaped stainless steel spring sheet, and the two side walls of the stainless steel spring sheet extend inward to form a U-shaped flange, and the stainless steel spring sheet is fixed to the limiting surface 13 by a fastener, and an annular groove is provided at the top of the clamping column 15. After the top of the clamping column 15 is clamped into the elastic holder 14, the U-shaped flange on the elastic holder 14 is clamped into the annular groove at the top of the clamping column 15, thereby temporarily fixing the clamping column 15 and the support frame 2. When the support frame 2 is flipped outward with force, the clamping column 15 can be pulled out of the elastic holder 14.

[0076] Furthermore, a fixing block is fixed on the middle wall surface inside the U-shaped elastic holder 14, which can prevent the two side walls of the elastic holder 14 from excessively deforming and bending inward. At the same time, a clearance hole for avoiding the card column 15 is opened on the fixing block, which does not affect the card column 15 being inserted into the elastic holder 14.

[0077] In the second aspect, in some optional embodiments: see Figures 4 to 8 As shown, an embodiment of the present application provides a front lower protection assembly, on which a mounting plate 16 for fixing to a vehicle frame and an anti-shake bracket 17 for fixing to a vehicle bumper are symmetrically mounted.

[0078] A symmetrically arranged mounting plate 16 is fixedly mounted on the front lower protection beam 10 of the front lower protection assembly of the embodiment of the present application. In the length direction of the front lower protection beam 10, two mounting plates 16 are respectively arranged on both sides of the movable step, so that the front lower protection beam 10 can be conveniently fixed to the frame of the vehicle through the mounting plates 16, thereby ensuring the installation reliability and use reliability of the front lower protection beam 10.

[0079] Furthermore, symmetrically arranged anti-shake brackets 17 are fixedly installed on the front lower protection beam 10. The two anti-shake brackets 17 are respectively arranged at the two ends of the front lower protection beam 10. The anti-shake brackets 17 at the two ends of the front lower protection beam 10 can fix the two ends of the front lower protection beam 10 and the upper bumper together, which can improve the rigidity of the lower area of ​​the bumper, prevent the bumper from shaking, and further enhance the practicality of the front lower protection assembly.

[0080] In the second aspect, in some optional embodiments: see Figures 4 to 8 As shown, an embodiment of the present application provides a front lower protection assembly, wherein both ends of the front lower protection cross beam 10 of the front lower protection assembly are fixed with upwardly extending mounting seats 18, a secondary step bracket 19 is fixedly mounted on the mounting seat 18, an anti-shake bent pipe 20 is fixedly connected between the secondary step bracket 19 and the adjacent mounting plate 16, and an anti-shake bracket 17 is fixed on the mounting seat 18.

[0081] Both ends of the front lower protection beam 10 of the front lower protection assembly of the embodiment of the present application are fixedly connected with an upwardly extending mounting seat 18, and a secondary step bracket 19 is fixedly mounted on the mounting seat 18. The mounting seat 18 can increase the installation height of the secondary step bracket 19 to prevent the front lower protection assembly from being too low from the ground after installation and failing to comply with relevant vehicle regulations.

[0082] At the same time, after the secondary step bracket 19 of the embodiment of the present application is raised to the installation position, it can be fixedly connected to the upper bumper, thereby improving the rigidity of the lower area of ​​the side bumper and preventing the bumper from shaking.

[0083] Furthermore, an anti-shake bent pipe 20 is fixedly connected between the secondary step bracket 19 and the adjacent mounting plate 16. The anti-shake bent pipe 20 can be installed or not according to the shaking condition of the bumper. After the anti-shake bent pipe 20 is installed, it can further improve the rigidity of the lower area of ​​the side bumper and prevent the bumper from shaking.

[0084] See also Figures 1 to 8 As shown, a third aspect of the embodiment of the present application provides a vehicle, including:

[0085] The front lower protection assembly of any of the above embodiments.

[0086] The vehicle of the embodiment of the present application adopts the front lower protection assembly of any of the above-mentioned embodiments. Since the movable step on the front lower protection assembly can adjust the step width, it has the advantage of occupying less space when folded up. When the movable step is flipped up and folded up, the movable step occupies less space front and back and up and down. Therefore, the problem of large space occupation caused by installing a step on the front lower protection beam 10 of the vehicle can be solved.

[0087] Specifically, the support frame 2 of the movable step of this embodiment is rotatably installed at the front end of the lower front protective beam 10 of the vehicle. When the movable step is flipped downward and opened to a horizontal state, the pedals 1 on both sides can be driven away from each other by the driving assembly, thereby widening the stepping width and improving the stepping comfort.

[0088] When the movable step is not in use, the driving assembly drives the pedals 1 on both sides to move closer to each other, thereby reducing the stepping width and further reducing the occupied space, making it convenient to flip the movable step upward and retract it, so that the movable step occupies less space in the Z direction in front of the vehicle and is not limited by the bumper above the front lower protective beam 10, i.e., it does not affect the layout of the components in front of the vehicle.

[0089] Exemplarily, in this embodiment, when the movable step on the front lower protective beam 10 of the vehicle is in a downward flipped open state, the length of the pedal area on the movable step is 800 mm, the width of the pedal area after widening is 30 mm, and the height of the pedal area from the ground is 40 mm, which meets the human-machine requirements while ensuring the strength and rigidity of the step. The basic dimensions of the newly added secondary step bracket 19 on the side are 335 mm in length, 170 mm in width, and 35 mm in height. The Z-direction height between the upper and lower pedals on the secondary step bracket 19 is 170 mm, which can provide a comfortable pedaling space.
