DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] In order to solve the technical problem in the prior art that commercial vehicles are prone to body imbalance during door opening, an embodiment of the present invention provides a step assembly, which drives the step to swing during boarding, making it easier for passengers to open the door, thereby eliminating safety hazards when passengers board the vehicle.

[0020] It should be noted that the step assembly described in the present invention is used for but not limited to commercial vehicles, etc. For the convenience of explanation, in the present invention, only the application of the step assembly to a commercial vehicle is used as an example for explanation, and the principles of the application of the step assembly to other types of equipment are essentially the same as those applied to commercial vehicles, and are not described in detail here.

[0021] The step assembly provided by the embodiment of the present invention is as follows: Figure 1 and 4As shown, it includes a step bracket 10, a swing frame 20, a lower step 30 and a driving member 40. The step bracket 10 is used to be fixedly connected to the vehicle body; the swing frame 20 is hinged to the step bracket 10; the lower step 30 is connected to the swing frame 20; the driving member 40 is connected to the swing frame 20 and the step bracket 10, and is used to drive the swing frame 20 to swing.

[0022] Specifically, the step assembly is provided with a step bracket 10, a swing frame 20, a lower step 30 and a driving member 40. The step assembly is fixedly connected to the vehicle body through the step bracket 10, the swing frame 20 is hinged to the step bracket 10, and the lower step 30 is connected to the swing frame 20. The swing frame 20 is hinged to the step bracket 10 and can swing relative to the step bracket 10. During the swinging of the step bracket 10 toward the door handle, the lower step 30 can be driven to move toward the door handle. The driving member 40 is connected to the swing frame 20, and can drive the swing frame 20 to swing toward the door handle when the occupant gets on the vehicle via the lower step 30, so that the occupant's body can be closer to the door handle, thereby making it easier for the occupant to touch the door handle, avoiding body imbalance in the process of touching the door handle, and eliminating the safety hazard of the occupant falling in the process of opening the door.

[0023] In the present embodiment, in the process of driving the swing frame 20 to swing toward the door handle, in addition to being able to drive the lower step 30 to move toward the door handle, the lower step 30 can also be lifted. On the one hand, it can make it easier for passengers with shorter stature to reach the door handle, and on the other hand, it can increase the ground clearance of the lower step 30 to avoid collision between the lower step 30 and ground obstacles.

[0024] In one embodiment, if Figure 1 As shown, a fixed bracket 11 is provided at the lower end of the step bracket 10, and a hinge shaft is provided at the fixed bracket 11, and a supply and rotation sleeve 21 is provided at the upper end of the swing bracket 20, and the supply and rotation sleeve 21 is sleeved on the hinge shaft, and the swing bracket 20 is hinged to the hinge shaft through the supply and rotation sleeve 21. The end of the fixed bracket 11 is fixedly connected to the vehicle body by three bolts, and the swing bracket 20 and the step bracket 10 are hinged by the cooperation of the supply and rotation sleeve 21 and the hinge shaft.

[0025] In this embodiment, the swing frame 20 can be any frame structure hinged to the step support 10 .

[0026] In one embodiment, if Figure 1 and 3 As shown in FIG. 4 , the swing frame 20 is provided with an air hole 22, which can reduce wind resistance.

[0027] In one embodiment, if Figure 5As shown, the swing frame 20 includes a first articulated frame 24 and a second articulated frame 25, the upper end of the first articulated frame 24 is hinged to the step bracket 10, the second articulated frame 25 is hinged to the lower end of the first articulated frame 24, the lower step 30 is connected to the second articulated frame 25, and the driving member 40 is connected to the first articulated frame 24. Specifically, the driving member 40 is connected to the first articulated frame 24, and by driving the first articulated frame 24 to move toward the door handle, the second articulated frame 25 and the lower pedal 53 can be driven to move toward the door handle. Since the ground clearance of the lower pedal 53 is small, it is easy to collide with ground obstacles. By setting the swing frame 20 as two mutually hinged first articulated frames 24 and second articulated frames 25, the lower end of the swing frame 20 can swing through the second articulated frame 25 when it hits a ground obstacle, so that the step assembly of the swing frame 20 can resist the impact of ground obstacles, and the swing frame 20 can be unaffected by the connection of the driving member 40 and can swing when it hits a ground obstacle.

[0028] In this embodiment, the hinge sleeve 241 of the first hinged frame 24 and the second hinged frame 25 is provided with a torsion spring (marked in the figure), one side of the torsion spring is in contact with the first hinged frame 24, and the other side of the torsion spring is in contact with the second hinged frame 25. The torsion spring can provide a buffer for the swing of the second hinged frame 25 to prevent the second hinged frame 25 from swinging too much when hit by external obstacles. At the same time, it can accelerate the resetting of the second hinged frame 25.

[0029] In this embodiment, Figure 5 As shown, a shaft sleeve 241 is fixed to the side of the first articulated frame 24, and a rotating shaft 251 is fixed to the side of the second articulated frame 25. The rotating shaft 251 is arranged on the inner side of the shaft sleeve 241. The second articulated frame 25 is hinged to the shaft sleeve 241 through the rotating shaft 251. The upper end surface of the second articulated frame 25 can be abutted against the lower end surface of the first articulated frame 24 by rotation. Specifically, by arranging the direction of the swing frame 20, the second articulated frame 25 can be rotated in the direction of the wheel under the impact of a ground obstacle, and when the second articulated frame 25 swings back, the upper end surface of the second articulated frame 25 abuts against the lower end surface of the first articulated frame 24, thereby preventing the second articulated frame 25 from swinging back further, thereby accelerating the reset of the second articulated frame 25.

[0030] In some embodiments, Figure 4 As shown, the lower step 30 is provided with a plurality of anti-skid protrusions 31 and a plurality of drainage holes 32, and the anti-skid protrusions 31 surround the drainage holes 32. Specifically, the anti-skid protrusions 31 can increase the surface friction of the lower step 30, and the drainage holes 32 can be used for drainage of the lower pedal 53 to prevent water from accumulating on the surface of the lower step 30. The anti-skid protrusions 31 surround the drainage holes 32, thereby increasing the strength of the surrounding side of the drainage holes 32 and preventing the lower step 30 from deforming.

[0031] In one embodiment, the driving member 40 includes a hydraulic cylinder (not shown in the figure), one end of the hydraulic cylinder is hinged to the step bracket 10, and the other end of the hydraulic cylinder is hinged to the swing frame 20. Specifically, the hydraulic cylinder drives the swing frame 20 to drive the swing frame 20 to swing.

[0032] In this embodiment, the driving end of the hydraulic cylinder is hinged to the first articulated frame 24 of the swing frame 20 close to the wheel side.

[0033] In another embodiment, Figure 4 As shown, the driving member 40 includes a motor 41, a rotating frame 42 and a driving frame 43. The motor 41 is fixed to the swing frame 20. The swing frame 20 is provided with a supporting frame 23. The rotating frame 42 is rotatably connected to the supporting frame 23. One end of the rotating frame 42 is hinged to the step bracket 10 through a straight groove. The driving frame 43 is fixed to the shaft of the motor 41 and is hinged to the straight groove at the other end of the rotating frame 42. Specifically, during the swinging process of the driving rod swing frame 20, the motor 41 drives the driving frame 43 to rotate. During the rotation process of the driving frame 43, the rotating frame 42 is driven to rotate while sliding along the straight groove by being hinged to one end of the straight groove of the rotating frame 42. During the rotation process of the rotating frame 42, the rotating frame 42 will slide along the step bracket 10 through the straight groove, and at the same time, a force acting on the step bracket 10 is formed. Since the step bracket 10 is fixed, at this time, the rotating frame 42 forms a reverse force, and finally drives the swing frame 20 to swing.

[0034] In this embodiment, the motor 41 is fixed to the first articulated frame 24 of the swing frame 20 at a side away from the wheel.

[0035] In this embodiment, Figure 4 As shown, the rotating sleeve 21 is provided with a connecting frame, and the rotating frame 42 is rotatably connected to the connecting frame through a straight groove. During the rotation of the rotating frame 42, it will slide along the connecting frame through the straight groove.

[0036] In one embodiment, if Figure 4 As shown, the rotating frame 42 is provided with a driving arm 421, and the driving arm 421 abuts against the swing frame 20, and can drive the swing frame 20 as the rotating frame 42 rotates. Specifically, the driving arm 421 abuts against the swing frame 20, and in the process of the motor 41 driving the rotating frame 42 to rotate, the driving arm 421 will form an additional driving force acting on the swing frame 20 to swing, and assist the swing frame 20 to swing, and then the swing frame 20 can be synchronously driven on both sides of the support frame 23, reducing the load of the motor 41.

[0037] In one embodiment, if Figure 1-3As shown, the step assembly also includes an upper step 50, which is fixed to the step bracket 10 and arranged above the lower step 30 along the height direction of the step bracket 10. Specifically, the step assembly forms a multi-level step by combining the lower step 30 and the upper step 50, which is convenient for passengers to get on the bus.

[0038] In this embodiment, Figure 1-3 As shown, there are two upper steps 50, which are spaced apart along the height direction of the pedal 53 bracket. The upper step 50 is combined with the lower step 30 to form a three-step structure.

[0039] In this embodiment, if the occupant is inexperienced, has low proficiency, or is not tall enough, after stepping on the upper step 50, the occupant presses a button to cause the drive member 40 to drive the swing frame 20 to swing, thereby lifting the lower pedal 53 and shifting it toward the door handle. The occupant steps on the lower step 30 again and can easily touch the door handle through the lower step 30. At this time, the body does not need to bend, or the door can be easily opened by turning sideways, thus avoiding body imbalance caused by touching the door handle and ensuring the safety of the occupant. After the door is opened, the occupant can get on the vehicle through the two upper steps 50.

[0040] In one embodiment, if Figure 2-3 As shown, the upper step 50 includes a support plate 51 and a step frame 52. Both ends of the support plate 51 and the step frame 52 are fixed to the step bracket 10. The step frame 52 is located on the upper side of the support plate 51 and forms a drainage gap with the support plate 51. Specifically, the step frame 52 can provide support for the passengers. When the passengers get on the vehicle, the step frame 52 slightly deforms downward and contacts the support plate 51, and is supported by the support plate 51, thereby ensuring the structural strength of the upper step 50 and preventing the upper step 50 from deforming. The step frame 52 is a hollow structure, and rainwater can directly enter the drainage gap of the support plate 51 through the step frame 52 and be discharged from the support plate 51, thereby avoiding the formation of water accumulation at the step frame 52, so that the passengers will not step on the water when getting on the vehicle. Therefore, by setting the upper step 50 as a support plate 51 and a step frame 52 structure, the structural strength of the upper step 50 can be effectively ensured, and the passengers can be effectively prevented from stepping on the water when getting on the vehicle.

[0041] In one embodiment, if Figure 2 As shown, the step frame 52 includes a plurality of U-shaped support frames 521 arranged in sequence from the inside to the outside, each adjacent U-shaped support frame 521 is fixedly connected, and the outermost U-shaped support frame 521 is fixed to the step frame 10. Specifically, through the side structure of the U-shaped support frame 521, the stability of the adjacent U-shaped support frames 521 and the stability of the outermost U-shaped support frame 521 and the step frame 10 can be achieved.

[0042] It can be understood that the number of U-shaped support frames 521 can be adaptively set according to actual needs.

[0043] In another embodiment, Figure 3 As shown, the step frame 52 includes an outer support frame 522 and a plurality of inner support frames 523 . The outer support frame 522 is fixed to the step bracket 10 , and the inner support frames 523 are arranged at intervals on the inner side of the outer support frame 522 and fixed to the outer support frame 522 .

[0044] In another embodiment, Figure 1 As shown, the upper step 50 includes a pedal 53, and the pedal 53 is provided with a plurality of drainage grooves 531 arranged at intervals, and friction protrusions are arranged inside the drainage grooves 531. Specifically, the drainage grooves 531 can receive the accumulated water on the surface of the pedal 53, and the friction protrusions can increase the surface friction of the pedal 53 on the one hand, and increase the strength of the pedal 53 on the other hand to prevent the pedal 53 from deforming.

[0045] The present invention also provides a vehicle, including the step assembly. Specifically, the vehicle is provided with the step assembly, so that the passenger can more easily touch the door handle when getting on the vehicle, avoiding the body imbalance caused by touching the door handle, and eliminating the safety hazard of the passenger falling when opening the door.

[0046] The specific working principle of the vehicle provided by the embodiment of the present invention is as follows: the vehicle of the present embodiment is mainly a commercial vehicle, which is provided with the step assembly on the vehicle body, the step assembly is located on one side of the wheel, the step assembly is provided with a step bracket 10, a swing bracket 20, a lower step 30 and a driving member 40, and is fixedly connected to the vehicle body and located on one side of the wheel through the step bracket 10, the swing bracket 20 is hinged to the step bracket 10, the lower step 30 is connected to the swing bracket 20, the swing bracket 20 is hinged to the step bracket 10, and can swing relative to the step bracket 10 toward the wheel direction, the step bracket 10 During the swinging process toward the wheel direction, the lower step 30 can be driven to move toward the door handle. The driving member 40 is connected to the swing frame 20, and can drive the swing frame 20 to swing toward the door handle when the passenger gets on the vehicle through the lower step 30. The driving member 40 can be controlled by a start-stop button on the vehicle body. After the passenger steps on the upper step 50 through the lower step 30, the start-stop button is pressed to drive the driving member 40 to drive the first articulated frame 24 of the swing frame 20, thereby driving the second articulated frame 25 and the lower step 30 to be lifted and moved toward the door handle. Then, the passenger steps on the lower step 30 again. The vehicle door can be easily opened by stepping on the lower step 30, and the body does not need to bend or turn sideways at this time, thus avoiding the body imbalance caused by touching the door handle, ensuring the safety of the occupants, and eliminating the potential safety hazard of falling when the occupants open the door. After the door is opened, the vehicle can be boarded by stepping on the two upper steps 50. Before boarding the vehicle, the start-stop button can be pressed again to start the driving member 40, so that the first articulated frame 24 is reset and the lower step 30 is driven to reset. After the lower step 30 is reset, the ground clearance of the lower step 30 is reduced, so that the lower step 30 can be easily opened. The step 30 is easy to collide with obstacles on the ground. Since the swing frame 20 is also provided with a second articulated frame 25 hinged to the first articulated frame 24, when the lower step 30 collides with a ground obstacle, it can swing through the second articulated frame 25 to avoid the lower step 30 from being deformed under the impact of the ground obstacle, so that the lower step 30 can meet the driving of the driving member 40 while reducing the impact of the ground obstacle. The torsion spring between the first articulated frame 24 and the second articulated frame 25, and the end face limit of the first articulated frame 24 and the second articulated frame 25 can significantly accelerate the resetting of the swing frame.

[0047] The specific implementation of the present invention described above does not constitute a limitation on the protection scope of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the protection scope of the claims of the present invention.
