Abstract

The invention discloses a cradle baby carriage which comprises a carriage frame with traveling wheels, a cradle swinging mechanism fixed on a carriage frame supporting pipe and a seat frame fixed on the cradle swinging mechanism, wherein the cradle swinging mechanism comprises a seat frame supporting arm, a rotating shaft and a fixed seat, the fixed seat is fixed on the carriage frame supporting pipe, the rotating shaft is obliquely arranged on the fixed seat, the axis direction of the rotating shaft is vertical to the longitudinal direction of the carriage frame, one end of the seat frame supporting arm is fixed on the rotating shaft and swings around the rotating shaft in an arc manner, and the other end of the seat frame supporting arm is hinged to the. The rotating shaft of the invention is obliquely arranged, so that the gravity center of the seat supporting arm connected with the rotating shaft generates height difference, energy conversion between kinetic energy and potential energy is generated in the swinging process, the seat freely swings along the frame along with the seat supporting arm around the rotating shaft, and meanwhile, because one end of the seat supporting arm is hinged at the bottom of the seat, one end of the seat supporting arm is fixed on the rotating shaft, the seat only swings along the front and back direction of the frame, and horizontal dislocation deflection cannot be generated.

Description

The cradle perambulator

Technical field

The present invention relates to a kind of perambulator, be specifically related to a kind of cradle perambulator.

Background technology

Perambulator is as a kind of general apparatus of supplying with children's use, and its comfort level and durability more and more receive publicity.Chinese patent ZL 951115340 discloses a kind of cradle style baby carriage, comprise vehicle frame, be arranged at wheel, the pushing hands connected to ground of vehicle frame bottom and be connected in stand on the vehicle frame, it is characterized in that also comprising a rocking equipment, this device comprises front roll bar, back fork, stand, the front portion of described vehicle frame, rear portion are hinged with front roll bar and back fork respectively, and the bottom of described front roll bar and back fork flexibly connects with the bottom of stand respectively.This cradle style baby carriage has the function of cradle, but it has certain shortcoming: this perambulator mechanism is comparatively complicated, and the speed of waving is very fast, impulsive force is arranged, be unfavorable for pacifying child, and structure is big, the cost height, bad returning the vehicle to the garage and knock off, and this cradle style baby carriage can only wave by manpower.

Summary of the invention

The present invention is big for the structure that overcomes existing cradle perambulator existence, cost is high and need manpower to wave and the degree of stability defect of bad, and a kind of cradle perambulator simple in structure, easy to use is provided.

The present invention can be achieved by taking following technical scheme:

A kind of cradle perambulator, comprise the vehicle frame that has road wheel, be fixed on the cradle swinging gear on the vehicle frame support tube and be fixed on mounting on the cradle swinging gear, described cradle swinging gear comprises mounting hold-down arm, S. A. and permanent seat, described permanent seat is fixed on the support tube of vehicle frame, described S. A. tilts to be installed on the permanent seat, and its axis direction is vertical with the longitudinal direction of vehicle frame, one end of described mounting hold-down arm is fixed on the S. A. and around S. A. does arc swing, and the other end is hinged on the bottom of mounting.

On the basis of the above, seat of the present invention hold-down arm is made of the single armed of a pair of horizontal positioned, S. A. is placed by main rotating shaft and secondary rotating shaft parallel and is constituted, one end of two single armeds all is hinged on the bottom of mounting, the other end is separately fixed on main rotating shaft and the secondary S. A., be with bearing between two single armeds of described seat hold-down arm and S. A.,, make its life-span longer in order to reduce the seat hold-down arm with main drive shaft with assist interaxle friction.

The present invention is further improved: this perambulator also comprises Vidacare corp, described Vidacare corp is fixed in the permanent seat and with main rotating shaft and is connected, described Vidacare corp comprises the motor in the shell with fixed seat, the drive gear casing that is connected with motor and the drive circuit board that links to each other with the motor electricity, described drive gear casing is connected with main rotating shaft, is used for the driven in rotation axle and drives seat hold-down arm swing.

Be provided with grating and sensor in the drive gear casing of the present invention, described grating is connected with the output shaft of motor, sensor is positioned at the side of grating and is electrically connected with the drive circuit board of Vidacare corp, by the detection of sensor and the control of electric circuit plate, the user is operation control panel as required, thus the motion of control perambulator.

The present invention does further to improve: on the support tube of the described vehicle frame relative with permanent seat fixed cover is installed, captive joint by pipe link between the housing of described fixed cover and Vidacare corp, described fixed cover is provided with the seat stay hook, described seat stay hook is buckled in the hold down groove of mounting, make at perambulator in the process that promotes, the seat can oneself wave along with moving of perambulator.

Compared with prior art, the present invention has the following advantages:

The present invention adopts S. A. to tilt to place, make the center of gravity of connection seat hold-down arm in the above produce diff-H, in swing process, produce the transformation of energy between kinetic energy and the potential energy, the seat is done along vehicle frame around S. A. and is freely swung along with the seat hold-down arm, simultaneously, because an end of seat hold-down arm is to be hinged on seat bottom, the one end is fixed on main rotating shaft and the secondary S. A., the seat only can or not produce the horizontal displacement deflection along the fore-and-aft direction swing of vehicle frame.In addition, perambulator of the present invention has also increased Vidacare corp, Vidacare corp is connected with S. A., the energy of seat hold-down arm institute's loss in swing process is replenished, and, be provided with grating and sensor in the Vidacare corp, by the detection of sensor and the control of electric circuit, the user can transfer the frequency and the amplitude of perambulator swing as required.The present invention is provided with stay hook, can make perambulator seat in pushing course can not produce swing.Baby carriage structure of the present invention is simple, and applicability is wide.
