Abstract
The utility model relates to a special safety door foot step for a school bus. The special safety door foot step comprises a footboard and is characterized by further comprising a support frame fixedly mounted at the lower end of a rear chassis of the bus, a guide plate fixedly mounted at the tail end of the footboard, a cylinder for driving the footboard to move and a transmission device. The hollow support frame is symmetrically provided with a pair of slide rails inside, pulleys fitted with the slide rails are symmetrically arranged at two ends of the guide plate, a guide rod is disposed in the middle of the guide plate, and guide bearings fitted with the guide rod are arranged in the middle of the guide plate. The special safety door foot step for the school bus is driven by the cylinder, stroke of a piston rod of the cylinder is horizontally enlarged by cross connecting rods, extending direction of the footboard is guaranteed by the guide bearings, the footboard can be extended without need to swing down, and accordingly the defect of insufficient underbody space is overcome, the extending size meets the national standard and the special safety door foot step is convenient to use, simple in structure and low in manufacturing cost.
Description
Technical field
The utility model relates to a kind of school bus Special safety door and marks time.
Background technology
The telescopic assembly of marking time that is applicable at present bus passenger door is mainly the swing telescopic structure, and the installing space that takies is larger, and relatively being applicable to the vehicle body one-level rear portion of marking time has installing space and mark time down and do not have the bus passenger door of obstacle.
Because the design of safety of school bus door is at the afterbody of automobile, the vehicle body one-level is marked time apart from about the about 700mm in ground, and there is not installing space after marking time, mark time down and also have some other car accessories, design the given activity attachment face of marking time and fixedly marking time about lower 270mm, because the height of 4.6.7 among the GB13094-2007 " requirement of passenger vehicle structural safety " between requiring to mark time and mark time must not be greater than 350mm.Therefore original oscillating type is marked time and is not suitable for this, among GB13094-2007 " requirement of the passenger vehicle structural safety " 4.6.7 also the requirement activity mark time must not be greater than 380mm apart from the maximum height on ground, owing to can not be lower than the nadir of passenger-carrying chassis after the safety of school bus door is marked time and installed, otherwise will affect the road crossing ability of passenger vehicle, for the sake of security, school bus tailstock safety door is marked time stretches out size and should be not less than 450mm, more than some all is that the existing yaw formula institute of marking time is unappeasable.
The utility model content
Technical problem to be solved in the utility model provides a kind of simple in structure, easy to use, safe, safety door step device of being applicable to various passenger vehicles and school bus.
The utility model adopts following technical scheme:
The present invention includes pedal, the cylinder and the driving device that characterized by further comprising the bracing frame that is fixedly installed in lower end, automobile tail chassis, the guide plate that is fixedly installed in the pedal end and be used for driving pedal travel, support frame as described above is that hollow structure and inboard are symmetrically arranged with a pair of slide rail, described guide plate two ends are symmetrically arranged with the pulley suitable with described slide rail, the support frame as described above middle part is provided with pilot bar, and described guide plate middle part is provided with the center bearing pilot bearing suitable with described pilot bar; Described driving device by connecting rod mechanism, be fixed in the first chute on the bracing frame and the second chute of being fixed on the guide plate forms, the termination of described connecting rod mechanism left upper portion and bracing frame are hinged, termination and the guide plate of bottom, described connecting rod mechanism left side are hinged, the termination of described connecting rod mechanism right upper portion is provided with pulley and described pulley is embedded in the first chute, and the termination of described connecting rod mechanism lower right side is provided with pulley and described pulley is embedded in the second chute; Described cylinder is fixedly installed on the outer ends of bracing frame by bearing pin, and the wheel shaft of the pulley in the piston rod of described cylinder and the second chute is hinged mutually.
Be provided with anti-skidding boss on the described pedal.
Be provided with alarming sign on the described pedal.
Good effect of the present utility model is as follows:
The utility model is by air cylinder driven, adopt the staggered form connecting rod, the stroke of cylinder piston rod has been carried out the level amplification, and guarantee the flexible direction of step plate with center bearing pilot bearing, make step plate need not both to have overcome the problem of car base space deficiency to the lower swing use of can stretching, stretch out simultaneously size and also reached the requirement of national standard, and easy to use, simple in structure, maintenance cost is low.
