Description

Vehicle is with the auxiliary device of getting on or off the bus

Technical field

The utility model relates to a kind of auxiliary device of getting on or off the bus, and refers to a kind of being applied on the full size vehicle especially, makes it that pedal auxiliary device that auxiliary people get on or off the bus can be provided.

Background technology

Present known full size vehicle is big because of its car body build, vehicle body is high, climbs up operator's saddle, compartment for ease of people, or goes down from operator's saddle, compartment, needs to install bottom this car body pedal conduct auxiliary device up and down usually.Early stage this pedal is taked the stationary structure design, because of this pedal extends laterally the car body outside, makes the elongated or bottom step-down of whole locomotive body width, and the problem that is unfavorable for vehicle ' is arranged.

For solving the shortcoming of said fixing formula pedal, there is the people promptly to design US5 at present as the U.S., 842, the auxiliary device of getting on or off the bus shown in No. 709 " RETRACTBLE; SWING DOWN STEP ASSEMBLY " patent cases, please cooperate and consult the shown in Figure 6 of this specification sheets, this auxiliary device of getting on or off the bus mainly is one can be fixedly arranged on the pedestal 60 of full size vehicle car body bottom, be provided with one group of power pack 61 in this pedestal 60 in conjunction with transmission component and servomotor 611, and with transmission output shaft 612 windings one first swing arm 62 of this power pack 61, other pivot joint one on pedestal 60 is parallel to second swing arm 63 of this first swing arm 62, and in first,

second swing arm

62,63 bottom mutual group is established a pedal 64, by this, make this auxiliary device of getting on or off the bus controlledly to make these power pack 61 driving first swing arms 62 and second swing arm 63 promote the place, car body below that vehicle is stretched out in pedals 64 swings, or make these pedal 64 side direction swings to pedestal 60 sides.

The use of the above-mentioned known auxiliary device of getting on or off the bus, but mat is controlled the downward swing of its pedal to the car body below, provide people to trample the ladder of usefulness, so that people get on or off the bus, when not required, then can make this pedal make progress swing, keep original width of this vehicle to the pedestal side, and do not cause at the bottom of the car lowly excessively, and then overcome the shortcoming that said fixing formula pedal can influence vehicle '.

Though the mechanism that this auxiliary device of getting on or off the bus of thought has telescopic action, but in this gets on or off the bus auxiliary device, because of its power pack is arranged on the rotary middle spindle of this swing arm and pedal with its transmission shaft, the arm of force length at this power pack point of application place is much smaller than the treadle effort arm lengths that is located at the swing arm end, so motor must provide bigger outputting power, and the big shortcoming of load is arranged, and, the auxiliary device of getting on or off the bus is taked the mechanism of side direction swing, and this swing arm is the design of asymmetric, in the process that auxiliary device advances with garage so this is got on or off the bus, easily, cause pedal and swing arm that the sagging facts is easily arranged because of the vibration of car body.

The utility model content

Main purpose of the present utility model is to provide a kind of vehicle with the auxiliary device of getting on or off the bus, and wishes design by this, in order to overcome shortcomings such as big resistance must be provided when the above-mentioned auxiliary device motor load of getting on or off the bus reaches load capacity greatly.

For reaching above-mentioned purpose, the technical scheme that the utility model proposed is to make this vehicle comprise a pedestal with the auxiliary device of getting on or off the bus, one power pack, two swing arm set and a pedal, this power pack is mounted on the pedestal, and with the transmission gear winding motor spindle of its gear cluster, each is hubbed on the pedestal with wheel shaft with two-phase ingear driven gear in this gear cluster in addition, this two swing arm set symmetry is mounted on outside the pedestal, it is to be articulated by first and second swing arm to form, and on each wheel shaft with this two driven gear of first swing arm upper end difference winding, be connected to this pedal one side with the first swing arm lower end mutual group in addition, by this, formation one can drive the auxiliary device of getting on or off the bus of pedal vertical lift.

The utility model is by the design of technique scheme, and compared to the aforementioned known auxiliary device of getting on or off the bus, advantage of the present utility model includes at least:

1. reduce the load of motor: because of the utility model auxiliary device of getting on or off the bus uses the swing arm set collocation of link-type to close gear cluster to be connected between power pack and the pedal, except that make this auxiliary device of getting on or off the bus have splendid easy to assembly, and use the length of lengthening propulsive effort point of action and pedal rotary middle spindle, make the motor of this power pack can drive this swing arm set and pedal lifting start by less outputting power.

2. be difficult for because of vibration sagging: the utility model auxiliary device of getting on or off the bus is to make this pedal connect the gear cluster that is positioned at pedestal by the swing arm set of two groups of symmetric offset spread, by this, this pedal is folded by this two swing arm set, cause has two swing arm set symmetry and enough bearing capacities of pedal is provided fifty-fifty, when it is advanced with garage, have difficult compared to prior art because of the sagging function of vibration.

3. provide less resistance during load capacity: same as above, the utility model is got on or off the bus after the swing arm set collocation gear cluster of auxiliary device mat link-type is connected between power pack and the pedal, the length of propulsive effort point of action and pedal rotary middle spindle can extend, so when people get on or off the bus and trample in this pedal, the fulcrum that the point of application arm of force of this power pack impedance of mat people pedal force and swing arm articulate has a segment length, so this power pack can provide less resistance can offset the application force that people trample the long-range pedal of swing arm, and then the loss of reduction power pack, prolong its service life.
