As shown in fig. 1 to 3, in one exemplary embodiment of the lower-turn two-stage electric step of the present invention, the lower-turn two-stage electric step includes a support frame 1, a link assembly 2, a step plate 3, and a driving motor 4.

The supporting frame 1 is fixed on the chassis of the vehicle, and the two connecting rod assemblies 2 are respectively arranged at the left side and the right side of the supporting frame 1. The two step plates 3 are respectively a first-stage step plate 31 and a second-stage step plate 32, and the step plates 3 are both installed between the two connecting rod assemblies 2. The driving motor 4 is arranged on the supporting frame 1 and drives the two connecting rod assemblies 2 to move synchronously, so that the two stepping plates 3 extend out of one side of the chassis to get on or off the chassis or retract to the lower part of the chassis.

The link assembly 2 includes a first swing lever 21, a second swing lever 22, a third swing lever 23, a first support lever 24, and a second support lever 25. The top of the first swing lever 21 is hinged to the rear of the support frame 1 and the bottom is hinged to the rear of the first support bar 24. The second swinging lever 22 is hinged at the top to the front of the support frame 1, at the middle to the middle of the first support bar 24 and at the bottom to the rear of the second support bar 25. The third swing lever 23 is hinged at the top to the front of the first support bar 24 and at the bottom to the middle of the second support bar 25. Both ends of the first-stage step plate 31 are fixed to the front portions of the corresponding first support bars 24, respectively, and both ends of the second-stage step plate 32 are fixed to the front portions of the corresponding second support bars 25, respectively.

The support frame 1, the upper portions of the first and second swing levers 21 and 22, and the rear portion of the first support lever 24 constitute a four-link structure, and the front portion of the first support lever 24, the lower portion of the second swing lever 22, the third swing lever 23, and the rear portion of the second support lever 25 constitute a four-link structure. The connecting rod assembly 2 has two four-connecting rod structures, so that under the condition that the three swinging rods swing downwards, the front parts of the two supporting rods are kept transverse, and the two stepping plates 3 extend or retract transversely.

The first swinging rod 21 or the second swinging rod 22 swings to the front side under the driving of the driving motor 4, so that the two supporting rods move forwards, the two stepping plates 3 move along with the two supporting rods, and the two stepping plates extend out of one side of the vehicle chassis from the lower part of the vehicle chassis, as shown in fig. 2, the downward-rotating two-stage electric stepping is switched to a working state, and the two stepping plates 3 form two stages, so that the high chassis can get on and off; the first swing lever 21 or the second swing lever 22 swings to the rear side under the driving of the driving motor 4, so that the two support plates move backward, the two tread plates 3 move accordingly, and then the tread plates return to the lower part of the vehicle chassis, as shown in fig. 3, the lower-rotation two-stage electric tread is switched to the retracted state, and the vehicle is guaranteed to run. The two connecting rod assemblies 2 move synchronously, so that the two sides of the step plate 3 move synchronously, and the step plate 3 stably extends out and retracts. As shown in fig. 3, in the retracted state, the distance between the three swing levers and the distance between the support rods are reduced to the greatest extent, and the two swing levers are substantially aligned in the vertical direction, the swing levers are both located within the length space range of the support rods, and the connecting rod assembly 2 occupies less space in the front-back direction and the height direction, so that the vehicle trafficability is ensured.

In above-mentioned exemplary embodiment, the electronic link assembly 2 of marking time of second grade of pronating only has five connecting rods, simple structure to having realized receiving and releasing of two flier pronating modes, the during operation forms the two-stage step, satisfies the demand that high chassis got on or off the bus, and the space occupies for a short time when packing up, guarantees vehicle trafficability characteristic, the good demand that has satisfied high chassis vehicle, has solved the problem that current car was marked time and can't well satisfy high chassis demand.

In some embodiments, as shown in fig. 1, the supporting frame 1 is provided with a rotating shaft 5, and two ends of the rotating shaft 5 are respectively connected to the corresponding first swing levers 21. The pivot axis 5 allows the first pivoting levers 21 to be mounted in a hinged manner, while the two first pivoting levers 21 are pivoted synchronously. The driving motor 4 drives the rotating shaft 5 to rotate, so that the first swing rod 21 swings synchronously, the two connecting rod assemblies 2 move synchronously, and the two stepping plates 3 extend out and retract stably.

In some embodiments, the rear portion of the first support bar 24 is bent upward with respect to the front portion, and the rear portion of the second support bar 25 is bent upward with respect to the front portion. The tilting of the rear portions of the two support rods reduces the required length of the first and second swing levers 21 and 22 while ensuring that the step plate 3 can be extended and lowered to a desired height, thereby reducing the space occupation of the swing levers in the front-rear direction in the retracted state.

In some embodiments, when the lower-turn two-stage electric step is in operation, the first bearing seat 26 provided at the bottom end of the first swing lever 21 is pressed against the second swing lever 22, and the second bearing seat 27 provided at the bottom end of the second swing lever 22 is pressed against the third swing lever 23. Under operating condition, first swinging arms 21 can play vertical support to second swinging arms 22 to a certain extent, and second swinging arms 22 also can play vertical support to third swinging arms 23 to a certain extent to improve the stability of two bracing pieces, and then improve the stability of step board.

In some embodiments, the first bearing seat 26 is raised with respect to the end of the first oscillating lever 21 and the second bearing seat 27 is raised with respect to the second oscillating lever 22. Two bellied bearing can separate certain interval between the swinging arms under operating condition, prevent that link assembly 2 moving range is too big to make the anterior downward swing of bracing piece, the 3 levels of footboard when guaranteeing to get on or off the bus, trample steadily.

In some embodiments, the rubber pad 6 is sleeved on each of the second swing lever 22 and the third swing lever 23. When the downward rotation two-stage electric step is in a working state, the first supporting seat 26 and the second supporting seat 27 both prop against the corresponding rubber pads 6. The rubber pad 6 plays a role in buffering, collision is avoided when the supporting seat contacts the swinging rod, friction is prevented from occurring between the supporting seat and the swinging rod, abrasion is avoided, and the service life is prolonged.

In some embodiments, the front portion of the first support bar 24 is flush with the first-level tread plate 31, and the front portion of the second support bar 25 is flush with the second-level tread plate 32, so that the formed tread is flat, and the treadable width is increased. When the electronic mark time of second grade of spiraling is in operating condition, the equal level setting of one-level flier 31 and second grade flier 32 guarantees that getting on or off the bus tramples steadily.

Finally, it should be noted that: the embodiments in the present description are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other.

The above examples are only intended to illustrate the technical solution of the present invention and not to limit it; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art will understand that: modifications to the specific embodiments of the utility model or equivalent substitutions for parts of the technical features may be made; without departing from the spirit of the present invention, it is intended to cover all aspects of the utility model as defined by the appended claims.
